Independent Predictor Of Poor Outcome Research Articles

Clinical factors associated with functional outcomes in patients with single subcortical infarction with neurological deterioration.

Factors that predict poor outcomes in patients with single subcortical infarction (SSI) may differ from those that predict poor outcomes in the SSI subgroup with neurological deterioration (ND). This study aimed to investigate the effect of ND on functional outcomes in patients with SSI and the clinical factors that predict poor outcomes in patients with SSI with ND (SSI-ND) and in all patients with SSI. Patients with SSI were consecutively enrolled in this study. ND was defined as an increase of ≥2 points in the National Institutes of Health Stroke Scale (NIHSS) total score, an increase of ≥1 point in the NIHSS subscore of consciousness or motor function, or any new neurological deficit. A total of 255 patients were enrolled, and nine (3.53%) were lost to a follow-up. ND [adjusted relative risk (aRR) = 1.37, 95% confidence interval (CI) = 1.22-1.55, p < 0.001], female sex (aRR = 1.13, 95% CI = 1.03-1.24, p = 0.12), initial NIHSS (aRR = 1.08, 95% CI = 1.07-1.10, p < 0.001), and parental arterial disease (PAD) (aRR = 1.16, 95% CI = 1.07-1.26, p = 0.038) were associated with a poor 90-day outcome (the modified Rankin scale (mRS) > 2 points) in patients with SSI. In the SSI-ND subgroup, PAD (aRR = 2.15, 95% CI = 1.20-3.86, p = 0.01), glycosylated hemoglobin (aRR = 1.17, 95% CI = 1.01-1.35, p = 0.035), and severe NIHSS (aRR = 1.15, 95% CI = 1.06-1.25, p = 0.001) were predictive of a poor outcome, and PAD (aRR = 1.87, 95% CI = 1.19-2.95, p = 0.007) was correlated with higher/worsened NIHSS [> 2 points (median)]. For predicting poor outcomes in patients with SSI-ND with PAD, a more severe NIHSS (aRR = 1.09, 95% CI = 1.02-1.17, p = 0.01) was the only determinant, with a cutoff of 4.5 points, a sensitivity of 94.0%, and a specificity of 83.3%. ND is an independent predictor of poor outcomes in patients with SSI, and poor outcome determinants in the SSI-ND subgroup and in all patients with SSI are not identical. For patients with SSI-ND, PAD could aggravate ND and was therefore an essential predictor of poor outcomes.

A nomogram for predicting the risk of poor prognosis in patients with poor-grade aneurysmal subarachnoid hemorrhage following microsurgical clipping.

Aneurysmal subarachnoid hemorrhage (aSAH) is a common and potentially fatal cerebrovascular disease. Poor-grade aSAH (Hunt-Hess grades IV and V) accounts for 20-30% of patients with aSAH, with most patients having a poor prognosis. This study aimed to develop a stable nomogram model for predicting adverse outcomes at 6 months in patients with aSAH, and thus, aid in improving the prognosis. The clinical data and imaging findings of 150 patients with poor-grade aSAH treated with microsurgical clipping of intracranial aneurysms on admission from December 2015 to October 2021 were retrospectively analyzed. Least absolute shrinkage and selection operator (LASSO), logistic regression analyses, and a nomogram were used to develop the prognostic models. Receiver operating characteristic (ROC) curves and Hosmer-Lemeshow tests were used to assess discrimination and calibration. The bootstrap method (1,000 repetitions) was used for internal validation. Decision curve analysis (DCA) was performed to evaluate the clinical validity of the nomogram model. LASSO regression analysis showed that age, Hunt-Hess grade, Glasgow Coma Scale (GCS), aneurysm size, and refractory hyperpyrexia were potential predictors for poor-grade aSAH. Logistic regression analyses revealed that age (OR: 1.107, 95% CI: 1.056-1.116, P < 0.001), Hunt-Hess grade (OR: 8.832, 95% CI: 2.312-33.736, P = 0.001), aneurysm size (OR: 6.871, 95% CI: 1.907-24.754, P = 0.003) and refractory fever (OR: 3.610, 95% CI: 1.301-10.018, P < 0.001) were independent predictors of poor outcome. The area under the ROC curve (AUC) was 0.909. The calibration curve and Hosmer-Lemeshow tests showed that the nomogram had good calibration ability. Furthermore, the DCA curve showed better clinical utilization of the nomogram. This study provides a reliable and valuable nomogram that can accurately predict the risk of poor prognosis in patients with poor-grade aSAH after microsurgical clipping. This tool is easy to use and can help physicians make appropriate clinical decisions to significantly improve patient prognosis.

Right Ventricular Strain in Patients With Ductal-Dependent Tetralogy of Fallot

Right ventricular (RV) dysfunction is an independent predictor of poor outcomes in patients with tetralogy of Fallot (TOF), and global longitudinal strain (GLS) is a well-validated echocardiographic technique to measure RV function. Although trends in RV GLS have been examined in patients with TOF, they have not been studied specifically in those with ductal-dependent TOF, a group in which there is not a clear consensus on the best surgical strategy. The aim of this study was to assess the midterm trajectory of RV GLS in patients with ductal-dependent TOF, drivers of this trajectory, and differences in RV GLS between repair strategies. This was a retrospective two-center cohort study of patients with ductal-dependent TOF who underwent repair. Ductal dependence was defined as being initiated on prostaglandin therapy and/or undergoing surgical intervention on or before 30days of life. RV GLS was measured on echocardiography preoperatively, early after complete repair, and at 1 and 2years of age. RV GLS was trended over time and compared between surgical strategies and with control subjects. Mixed-effects linear regression models were used to evaluate the factors associated with changes in RV GLS over time. Forty-four patients with ductal-dependent TOF were included in the study, of whom 33 (75%) underwent primary complete repair and 11 (25%) underwent staged repair. Complete TOF repair was performed at a median of 7days in the primary-repair group and 178days in the staged-repair group. RV GLS improved over time from post-complete repair echocardiography through 2years of age (-17.4% [interquartile range, -15.5% to -18.9%] vs -21.5% [interquartile range, -18.0% to -23.3%], P<.001). However, compared with age-matched control subjects, patients had worse RV GLS at all time points. There was no difference in RV GLS between the staged and primary complete repair groups at 2-year follow-up. Shorter intensive care unit length of stay after complete repair was independently associated with improvement in RV GLS over time. Strain improved by 0.07% (95% CI, 0.01 to 0.12) for each fewer day in the intensive care unit (P=.03). RV GLS improves over time among patients with ductal-dependent TOF, though it is consistently reduced compared with control subjects, suggesting an altered deformation pattern in patients with ductal-dependent TOF. There was no difference in RV GLS between the primary- and staged-repair groups at midterm follow-up, suggesting that repair strategy is not a risk factor for worse RV strain in the mid postoperative period. A shorter complete-repair intensive care unit length of stay is associated with an improved trajectory of RV GLS.

Postoperative clinical outcomes of patients with thymic epithelial tumors after over-3-year follow-up at a single-center

BackgroundTo evaluate postoperative clinical outcomes and analyze influencing factors for patients with thymic epithelial tumors over 3 years after operation.MethodsPatients with thymic epithelial tumors (TETs) who underwent surgical treatment in the Department of Thoracic Surgery at Beijing Hospital from January 2011 to May 2019 were retrospectively enrolled in the study. Basic patient information, clinical, pathological, and perioperative data were collected. Patients were followed up by telephone interviews and outpatient records. Statistical analyses were performed using SPSS version 26.0.ResultsA total of 242 patients (129 men, 113 women) with TETs were included in this study, of which 150 patients (62.0%) were combined with myasthenia gravis (MG) and 92 patients (38.0%) were not. 216 patients were successfully followed up and their complete information was available. The median follow-up period was 70.5 months (range, 2–137 months). The 3-year overall survival (OS) rate of the whole group was 93.9%, and the 5-year OS rate was 91.1%. The 3-year relapse-free survival (RFS) rate of the whole group was 92.2%, and the 5-year relapse-free survival rate was 89.8%. Multivariable COX regression analysis indicated that recurrence of thymoma was an independent risk factor for OS. Younger age, Masaoka-Koga stage III + IV, and TNM stage III + IV were independent risk factors for RFS. Multivariable COX regression analysis indicated that Masaoka-Koga staging III + IV, WHO type B + C were independent risk factors for postoperative improvement of MG. For patients with MG, the postoperative complete stable remission (CSR) rate was 30.5%. And the result of multivariable COX regression analysis showed that thymoma patients with MG with Osserman staging IIA + IIB + III + IV were not prone to achieving CSR. Compared with patients without MG, MG was more likely to develop in patients with WHO classification type B, and patients with myasthenia gravis were younger, with longer operative duration, and more likely to develop perioperative complications.ConclusionsThe 5-year overall survival rate of patients with TETs was 91.1% in this study. Younger age and advanced stage were independent risk factors for RFS of patients with TETs, and recurrence of thymoma were independent risk factors for OS. In patients with MG, WHO classification type B and advanced stage were independent predictors of poor outcomes of MG treatment after thymectomy.

The Switch/Sucrose Non-Fermentable (SWI/SNF) protein complex functions as a tumour suppressor through chromatin remodelling. Mutations in genes that encode complex subunits have been identified in a rare subset of aggressive poorly differentiated malignancies across anatomical sites, including thorax, gastrointestinal, genitourinary and sinonasal tracts.1,2 The mutations are independent predictors of poor outcome. Cases presenting as isolated lymphadenopathy are uncommon.3

Outcome of COVID-19-Associated Acute Stroke: A Study from South India.

Coronavirus 2019 (COVID-19) infection is prevalent worldwide. COVID-19 infection can lead to various neurological disorders including acute stroke. We investigated the functional outcome and its determinants among our patients with acute stroke associated with COVID-19 infection in the present setup. This study is a prospective study in which we recruited acute stroke patients with COVID-19 positivity. Data on duration of COVID-19 symptoms and type of acute stroke were recorded. All patients underwent stroke subtype workup and measurement of D-dimer, C-reactive protein (CRP), lactate-dehydrogenase (LDH), procalcitonin, interleukin-6, and ferritin levels. Poor functional outcome was defined by modified Rankin score (mRS) ≥3 at 90 days. During the study period, 610 patients were admitted for acute stroke, of whom 110 (18%) tested positive for COVID-19 infection. Majority (72.7%) were men with a mean age of 56.5 years and mean duration of COVID-19 symptoms for 6.9 days. Acute ischemic and hemorrhagic strokes were observed in 85.5% and 14.5% patients, respectively. Poor outcome was observed in 52.7%, including in-hospital mortality in 24.5% patients. COVID-19 symptoms ≤5 days (odds ratio [OR]: 1.41, 95% confidence interval [CI]: 1.20-2.99), CRP positivity (OR: 1.97, 95% CI: 1.41-4.87), elevated levels of D-dimer (OR: 2.11, 95% CI: 1.51-5.61), interleukin-6 (OR: 1.92, 95% CI: 1.04-4.74), and serum ferritin (OR: 2.4, 95% CI: 1.02-6.07), and cycle threshold (Ct) value ≤25 (OR: 8.8, 95% CI: 6.52-12.21) were independent predictors of poor outcome. Poor outcomes were relatively higher among acute stroke patients with concomitant COVID-19 infection. In the present study, we established the independent predictors of poor outcome to be onset of COVID-19 symptoms (<5 days) and elevated levels of CRP, D-dimer, interleukin-6, ferritin, and Ct value ≤25 in acute stroke.

Naples Prognostic Score Predicts 6-Month Outcomes in Patients with Severe Traumatic Brain Injury: A Single-Center Retrospective Study.

To examine how Naples prognostic score (NPS) relates to 6-month outcomes in patients with severe traumatic brain injury (STBI). We retrospectively analyzed the clinical data of 94 patients with STBI between September 2018 and September 2021. Galizia?s method was used to calculate NPS, and patients were categorized as high (NPS > 3) or low (NPS?3) NPS according to their NPS scores based on receiver operating characteristic curve analysis. In addition, the controlling nutritional status score (CONUT) and prognostic nutrition index (PNI) were calculated. Based on the modified Rankin scale (mRS), the outcome for 6-months was evaluated. The mRS score for unfavorable outcomes was ?3. In the univariate analyses, patients in the unfavorable group had higher NPS scores (p < 0.001). The multivariate analysis demonstrated that NPS was an independent predictor of poor outcomes after adjusting for potential confounding factors (adjusted odds ratio = 7.463, 95% confidence interval [CI]: 1.131?49.253, p < 0.05). The area under the NPS curve for predicting poor outcomes was 0.755 (95% CI: 0.655?0.837, p < 0.001), which was significantly higher than Glasgow coma score (GCS), CONUT, and PNI (NPS vs. GCS, p=0.013; NPS vs. CONUT, p=0.029; NPS vs. PNI, p=0.015). NPS can be considered to be a novel and better independent predictor of poor outcomes in patients with STBI.

Advanced nurse specialist-managed pediatric extracorporeal membrane oxygenation: A 35-year single center experience

Aim: To investigate the feasibility, safety, and clinical outcomes of a solely registered nurse (RN)-managed extracorporeal membrane oxygenation (ECMO) program in a community hospital over a 35-year period. Material and Methods: A retrospective single-center review was conducted on all patients who received at least 24 hours of ECMO support in our pediatric intensive care unit (PICU) between August 1987 and August 2021. An integrated study of ECMO support type, ECMO duration, and patient survival to discharge was systematically performed. Results: 321 ECMO runs were initiated on 319 patients. 273 (85.0%) runs were for elective pulmonary support, 34 (10.6%) were for elective cardiac support, and 14 (4.36%) were for emergent cardiac support in extracorporeal cardiopulmonary resuscitation (ECPR). Of the 321 ECMO runs, 279 (86.9%) were performed on neonatal patients, 37 (11.5%) on pediatric patients, and 5 (1.56%) on adult patients (excluded from analysis). The median duration of ECMO was 120 hours for neonatal patients and 134 hours for pediatric patients. 69.5% of all patients on ECMO survived to discharge. ECPR was an independent predictor of poor outcomes, in which 28.6% of the 14 patients survived to discharge. Conclusion: A pediatric ECMO program fully managed by advanced nurse specialists was successfully implemented, maintained, and expanded. This model produced safe and efficacious outcomes that were comparable to data from the Extracorporeal Life Support Organization (ELSO) registry. Such an ECMO model is feasible even in a resource-limited setting like a community hospital. Nevertheless, for the most critical patients, the support of neonatologists, intensivists, and surgeons is imperative for enhancing favorable outcomes.

Profile of pulmonary hypertension amongst patients seen with left heart failure in a Ghanaian hospital

We assessed the burden and predictors of pulmonary hypertension amongst patients with left heart failure presenting to the cardiology unit of Korle Bu Teaching Hospital, Ghana.

Spontaneous Intracerebral Hemorrhage in the Young: An Institutional Registry Analysis

Abstract Background: Spontaneous intracerebral hemorrhage (SICH) accounts for about 10–15% of all strokes. Generally, it is a disease of the elderly; worldwide, the incidence of SICH in the young is showing an increasing trend, especially in India and the Asian continent. An attempt is also made to analyze the presence of factors, which may predict the risk of SICH among young hypertensives. Methods: A six-year retrospective review of patients aged below 50 years who presented with SICH was included in the study. Patients with bleeds secondary to an identifiable cause such as tumor, trauma, vascular malformations, and coagulopathy-induced bleeds were excluded from the study. The outcome was measured at 90 days using the modified ranking scale, and predictors of outcome (good outcome modified ranking score (mRS): 0–3; poor outcome mRS: 4–6) were analyzed. Results: SICH in the young accounted for 28.4% of all intracerebral hemorrhage (ICH) patients admitted during the study period (344/1210). The mean age of our male-dominant (78.5%) cohort was 42.9 ± 6.24 years, and the median Glasgow coma score (GCS) on presentation was 11 (IQR: 8–14). A prior history of hypertension (HTN) was obtained in 51.2% (176), and left ventricular hypertrophy (LVH) was documented in 237 (68.9%) patients. The basal ganglia was the most common location of the bleed (62.2%). At 90 days, 200 patients (58.1%) had good outcome and 144 (41.9%) had poor outcome with an overall mortality of 75 (21.8%). Independent predictors of poor outcome were poor GCS, larger volume, and high serum creatinine values. Conclusion: The incidence of SICH among the young accounts for nearly 30% of admitted ICH. Poor outcome and mortality are high with HTN being the single most important modifiable risk factor in the cohort.

Prehospital Ultra-Early Neurological Deterioration in Intracerebral Hemorrhage: Definition, Prevalence, and Association with Outcomes

Introduction: The objective of this study was to define prehospital ultra-early neurological deterioration (UND) and to investigate the association with functional outcomes in patients with intracerebral hemorrhage (ICH). Methods: We conducted a prospective cohort study of consecutive acute ICH patients. The stroke severity at onset and hospital admission was assessed using the Chongqing Stroke Scale (CQSS), and prehospital UND was defined as a CQSS increase of ≥2 points between symptoms onset and admission. Early neurological deterioration (END) was defined as the increase of ≥4 points in NIHSS score within the first 24 h after admission. Poor outcome was defined as a modified Rankin Scale (mRS) of 4–6 at 3 months. Results: Prehospital UND occurred in 29 of 169 patients (17.2%). Patients with prehospital UND had a median admission NIHSS score of 17.0 as opposed to those without prehospital UND with a median NIHSS score of 8.5. There were three patterns of neurological deterioration: prehospital UND only in 21 of 169 patients (12.4%), END but without prehospital UND in 20 of 169 patients (11.8%), and continuous neurological deterioration in both phases in 8 patients (4.7%). Prehospital UND was associated with worse 3-month outcomes (median mRS score, 4.0 vs. 2.0, p = 0.002). After adjusting for age, time from onset to admission, END, and systolic blood pressure, prehospital UND was an independent predictor of poor outcome (odds ratio [OR] 3.27, 95% confidence interval [CI] 1.26–8.48, p = 0.015). Conclusion: Prehospital UND occurs in approximately 1 in 7 patients between symptom onset and admission and is associated with poor functional outcome in patients with ICH. Further research is needed to investigate the prehospital UND in the prehospital phase in the triage of patients with ICH.

A clinical analysis of hemophagocytic syndrome secondary to autoimmune diseases.

This study aimed to analyze the differences of etiologies and clinical features between patients with autoimmune-associated hemophagocytic syndrome (AAHS) and those with other underlying diseases of hemophagocytic syndrome (HPS). The retrospective study was performed with 130 HPS patients (70 males, 60 females; mean age: 50.4±18.1 years; range, 13 to 85 years) between January 1st, 2011, and April 1st, 2022. The patients fulfilled at least five of the eight criteria proposed by the Histiocytosis Society in 2004. The underlying diseases related to HPS were divided into four categories: autoimmune, infection, malignancy and idiopathic diseases. And the clinical manifestations, laboratory examinations, treatments, and prognosis were analyzed respectively. Nineteen (14.6%) patients had AAHS, 45 (34.6%) had infection-associated HPS, 57 (43.8%) had malignancy-associated HPS, and nine (6.9%) had idiopathic HPS. The most common symptoms of HPS were unremitting fever in 123 (94.6%) of 130 patients and splenomegaly in 92 (70.8%). All patients manifested a decline of at least two lineages of hematopoietic cells. The absolute values of T cells and B cells of AAHS were significantly higher than that of malignancy-associated HPS. The levels of soluble CD25 (interleukin-2 receptor) of AAHS were the lowest among all-cause HPS (p<0.05). The all-cause mortality rate of hospitalized patients with HPS was 46.2%. The patients with AAHS had a better prognosis compared to other etiologies (odds ratio [OR]=0.091, 95% confidence interval [CI]: 0.011-0.775, p=0.028). Epstein-Barr virus infection (OR=4.761, 95% CI: 1.619-14.004, p=0.005) and pulmonary involvement (OR=4.555 95% CI: 1.524-13.609, p=0.007) were independent predictors of poor outcome in HPS. Thrombocytopenia (OR=0.978, 95% CI: 0.968-0.999, p=0.040) had a boundary effect on prognosis. Patients with HPS secondary to autoimmune disease have better outcomes compared to patients complicated with Epstein-Barr virus infection or pulmonary involvement.

Systemic immune-inflammation index for predicting poor outcome after carotid endarterectomy: A novel hematological marker.

To investigate the predictive role of systemic immune-inflammation index (SII) on postoperative poor outcome in patients undergoing carotid endarterectomy (CEA). A total of 347 patients undergoing elective isolated CEA between March 2010 and April 2022 were included in this multicenter retrospective observational cohort and risk-prediction study and were divided into two groups as poor outcome group (n = 23) and favorable outcome group (n = 324). Poor outcome was defined as the presence of at least one of the complications within 30 days of surgery including stroke, myocardial infarction, and death. The patients' baseline clinical characteristics, comorbidities, and hematological indices were derived from the complete blood count (CBC) analysis, and perioperative data, outcomes, and complications were screened, recorded, and then compared between the groups. Multivariate logistic regression and receiver-operating characteristic (ROC) curve analyses were conducted following univariate analyses to detect the independent predictors of poor outcome as well as the cutoff values with sensitivity and specificity rates. A total of 23 patients out of 347 (6.6%) manifested poor outcome; and stroke, myocardial infarction, and death occurred in 13, 3, and 7 cases, respectively. There were no significant differences between the groups in terms of basic clinical characteristics, comorbidities, and perioperative data, except for lengths of intensive care unit and hospital stays. Although the median values of PLT, PLR, NLR, and SII of the poor outcome group were found to be significantly higher than the favorable outcome group in univariate analysis, only SII was detected to be a significant and independent predictor of poor outcome in multivariate logistic regression analysis (OR = 1.0008; 95% CI: 1.0004-1.0012; p = 0.002). ROC curve analysis revealed that SII of 1356 × 103/mm3 constituted the cutoff value for predicting poor outcome with 78.3% sensitivity and 64.5% specificity (AUC = 0.746; 95% CI: 0.64-0.851). Our study revealed for the first time in the literature that SII significantly predicted poor outcome after CEA.

COVID-19 independently predicts poor outcomes in Acute Ischemic Stroke- Insights from a multicenter study from Pakistan and United Arab Emirates

BackgroundIschemic stroke associated with coronavirus 2019 (COVID-19) has been well recognized by now. Few studies have compared COVID related versus unrelated strokes. We intend to report on a large group of Asian patients from two countries and compare COVID with non-COVID strokes admitted during the same time period. MethodsConsecutive cases of acute ischemic stroke either presenting or developing, between March 2020 and December 2021 in four tertiary care hospitals (1 in Dubai, UAE and 3 in Karachi, Pakistan) and testing positive for COVID-19 were included in the study. Patients admitted with ischemic stroke during the same time period and who tested negative for COVID-19 were also randomly selected from the four hospitals. All data was collected from the medical records of the patients and recorded on a standard questionnaire before it was entered in SPSS version 21 for analysis. ResultsThere were 139 COVID positive and 271 COVID negative patients with acute ischemic stroke included in the current study. There were significantly more males (80.6% vs 64.9%, p=0.001) and more large vessel strokes in the COVID positive group (41% vs 21.8%, p<0.001). Being COVID positive was an independent predictor of poor outcome at discharge, defined as a modified Rankin score of 3-6 (OR 3.87, 95% CI 2.21-6.77) after adjusting for country, age, sex, vascular comorbid conditions and stroke subtype. ConclusionsIn this largest series of patients with COVID related strokes from Asia, COVID-19 was an independent predictor of poor outcomes at discharge after adjusting for other variables.

Admission maximum amplitude-reaction time ratio: Association between thromboelastography values predicts poor outcome in injured children.

Thromboelastography (TEG)-derived maximum amplitude-reaction time (MA-R) ratio that accounts for both hypocoagulable and hypercoagulable changes in coagulation is associated with poor outcomes in adults. The relationship between these TEG values and outcomes has not been studied in children. In a retrospective cohort study, a level I pediatric trauma center database was queried for children younger than 18 years who had a TEG assay on admission between 2016 and 2020. Demographics, injury characteristics, and admission TEG values were recorded. The MA-R ratio was calculated and divided into quartiles. Main outcomes included mortality, transfusion within 24 hours of admission, and thromboembolism. A logistic regression model was generated adjusting for age, Injury Severity Score, injury mechanism, admission shock, and Glasgow Coma Scale. In total, 657 children were included, of which 70% were male and 75% had blunt mechanism injury. The median (interquartile range) age was 11 (4-14) years, the median (interquartile range) Injury Severity Score was10 (5-22), and in-hospital mortality was 7% (n = 45). Of these patients, 17% (n = 112) required transfusion. Most R and MA values were within normal limits. On unadjusted analysis, the lowest MA-R ratio quartile was associated with increased mortality (15% vs. 4%, 5%, and 4%, respectively; p < 0.001) and increased transfusion need (26% vs. 12%, 16%, and 13%, respectively; p = 0.002) compared with higher quartiles. In the logistic regression models, a low MA-R ratio was independently associated with increased in-hospital mortality (odds ratio [95% confidence interval], 4.4 [1.9-10.2]) and increased need for transfusion within 24 hours of admission (odds ratio [95% confidence interval], 2.0 [1.2-3.4]) compared with higher MA-R ratio. There was no association between MA-R ratio and venous thromboembolic events (venous thromboembolic event rate by quartile: 4%, 2%, 1%, and 3%). Although individual admission TEG values are not commonly substantially deranged in injured children, the MA-R ratio is an independent predictor of poor outcome. Maximum amplitude-reaction time ratio may be a useful prognostic tool in pediatric trauma; validation is necessary. Therapeutic/Care Management; Level III.

A potential novel inflammation biomarker for predicting the prognosis of decompensated liver cirrhosis

Objective This study aimed to explore the prognostic value of the lymphocyte (LYM)-to-white blood cell (WBC) ratio (LWR) in patients with decompensated liver cirrhosis (DLC). Methods This study was conducted by recruiting 214 patients with DLC with different aetiologies (development cohort). Receiver operating characteristic (ROC) curve analyses were used to assess the predictive accuracy of the LWR, and Youden’s index was used to determine the optimal cut-off values of the LWR based on the ROC curve. Next, patients were divided into high- and low-LWR groups according to the cut-off values. Multivariate logistic analyses were performed to determine the independent predictors for the 1-, 3- and 6-month mortality. Restricted cubic spline (RCS) was used to determine and visualize the association between LWR and the risk of death. We verified the predictive ability of LWR in the validation cohort of 139 patients. Results In the development cohort, there were 16 (7.5%), 22 (10.3%) and 30 patients (14.0%) who died at 1, 3 and 6 months, respectively. The LWR was significantly lower in non-survivors than in survivors and was an independent predictor of poor outcomes. The ROC analyses with the Delong test showed that the LWR had comparable predictive power with the Model for End-Stage Liver Disease (MELD) score, neutrophil-to-LYM ratio (NLR) and Chronic Liver Failure consortium score for acute decompensated (CLIF-C ADs). RCS showed a non-linear relationship between the LWR and the risk of death at 1 and 3 months, whereas a linear relationship was observed between the LWR and the risk of death at 6 months. We verified that the decreased LWR was an independent predictor of adverse outcomes at 3-, and 6-month follow-up endpoints in the validation cohort. Conclusions Our findings indicate that a lower LWR is an independent factor for unfavourable outcomes and may serve as a potential novel prognostic predictor in patients with DLC. KEY MESSAGES This study is the first report on the prognostic value of the lymphocyte (LYM)-to-white blood cell (WBC) ratio (LWR) in patients with decompensated liver cirrhosis (DLC). Decreased LWR is an independent factor for adverse outcomes in patients with DLC.

Predictors of Outcome of Aneurysmal Subarachnoid hemorrhage

Introduction: Aneurysmal Subarachnoid Hemorrhage (aSAH) is a devastating condition with high mortality and morbidity. Significant factors influencing the prognosis of aneurysmal subarachnoid hemorrhage (SAH) include the severity at presentation of the disease and delayed cerebral ischemia (DCI).&#x0D; Methods: This is a prospective study conducted in Upendra Devkota Memorial National Institute of Neurological and Allied Sciences (UDM-NINAS), Bansbari, Kathmandu, Nepal among patients who underwent clipping of aneurysm for subarachnoid hemorrhage. Various clinical and radiological prognostic factors were registered on admission and during the intensive care stay. Outcome was recorded. GOS&gt;3 was considered good outcome and GOS ≤3 was considered poor outcome.&#x0D; Results: Seventy-two patients with ruptured aneurysm were surgically clipped. Good outcome was observed in 51 (70.83%) patients while poor outcome was seen among 21 (29.17%) patients including death among 16 (22.2%) patients. In univariate analysis, WFNS&gt;2, Fisher grade &gt;2, EVD placement for hydrocephalus and delayed cerebral ischemia (DCI) were found to have statistically significant in poor outcome. On Multivariate logistic regression model showed delayed cerebral ischemia was statistically significant predictor of poor outcome at p= 0.032 (OR= 7.34; 95% CI=1.280 to 17.702).&#x0D; Conclusion: WFNS &gt;2, Fisher grade&gt;2, EVD placement and DCI were found to have statistical significance in poor outcome while only DCI was an independent predictor of poor outcome following aneurysmal Subarachnoid Hemorrhage (aSAH).

Intramural Component of Venous, Lymphatic, and Perineural Invasion in Colon Cancer: A Threat or an Illusion?

Extramural venous invasion is an independent predictor of poor outcome in colorectal cancer, whereas the significance of the intramural component of venous and lymphatic and perineural invasion is unclear. To evaluate the prognostic impact of intramural components for venous, lymphatic, and perineural invasions and the relation of these invasion patterns with clinicopathological features in patients with colon cancer. A retrospective cross-sectional study. The analysis included 626 patients with colon cancer in stages II and III. All patients were divided into four categories (no invasion, intramural invasion only, extramural invasion only, or both intramural and extramural invasions) for vascular invasion, lymphatic invasion and perineural invasion. The primary outcomes were 5-year disease-free and overall survival. Right-sided (for vascular invasion, 24.7% vs. 33.9%, p = 0.007; for perineural invasion, 34.5% vs. 41.5%, p = 0.034) and dMMR tumors (for vascular invasion, 13.5% vs. 33.5, p < 0.001; for perineural invasion, 25% vs. 41.4%, p = 0.004) exhibited less venous and perineural invasion. Compared with no invasion, presence of intramural invasion only, did not exert any effect on disease-free or overall survival for vascular invasion, lymphatic invasion, and perineural invasion. Multivariate analyses revealed that the presence of both intramural and extramural invasion was independently associated with poor disease-free and overall survival for venous (hazard ratios: 2.39, p = 0.001; hazard ratios: 2.46, p = 0.001), lymphatic (hazard ratios: 2.456, p < 0.001; hazard ratios: 2.13, p = 0.02) and perineural invasion (hazard ratios: 2.99, p < 0.001; hazard ratios: 2.68, p < 0.001), respectively. Our data strongly advocates the importance of reporting intramural and extramural components of invasion since the presence of intramural invasion alone may not be considered as a high-risk factor for systemic recurrence.

Patterns and Predictors of Timely Presentation and Outcomes of Polytrauma Patients Referred to the Emergency Department of a Tertiary Hospital in Tanzania

Polytrauma patients require special facilities to care for their injuries. In HICs, these patients are rapidly transferred from the scene or the first-health facility directly to a trauma center. However, in many LMICs, prehospital systems do not exist and there are long delays between arrivals at the first-health facility and the trauma center. We aimed to quantify the delay and determine the predictors of mortality among polytrauma patients. Methodology. We consecutively enrolled adult polytrauma patients (≥18 years) with ISS >15 referred to the Emergency Medicine Department of Muhimbili National Hospital, a major trauma center in Tanzania between August 2019 and January 2020. Based on a pilot study, the arrival of >6 hours after injury was considered a delay. The outcome of interest was factors associated with delayed presentation and the association of timeliness with 7-day mortality. We enrolled 120 (4.5%) referred polytrauma adult patients. The median age was 30 years (IQR 25-39) and the ISS was 29 (IQR 24-34). The majority (85%) were males. While the median time from injury to first-health facility was 40 minutes (IQR 33-50), the median time from injury to arrival at EMD-MNH, was 377 minutes (IQR 314-469). Delayed presentation was noted in more than half (54.2%) of participants, with the odds of dying being 1.4 times higher in the delayed group (95% CI 0.3-5.6). Having a GCS <8 (AOR 16.3 (95% CI 3.1-86.3), hypoxia <92% (AOR 8.3 (95% CI 1.4-50.9), and hypotension <90 mmHg (R 7.3 (95% CI 1.6-33.6) were all independent predictors of mortality. The majority of polytrauma patients arrive at the tertiary facilities delayed for more than 6 hours and a distance of more than 8 km between facilities is associated with delay. Hypotension, hypoxia, and GCS of less than 8 are independent predictors of poor outcome. In the interim, there is a need to expedite the transfer of polytrauma patients to trauma care capable centers.

ODP632 Preadmission Use Of Antidiabetic Medications And Mortality Among Patients With Covid-19 Having Type 2 Diabetes: A Meta-analysis

Abstract Introduction Diabetes is an independent predictor of poor outcomes in patients with COVID-19. We compared the effects of the preadmission use of antidiabetic medications on the in-hospital mortality of patients with COVID-19 having type 2 diabetes. Methods A systematic search was performed until November 30, 2021. We used a random-effects meta-analysis to calculate the pooled OR (95% CI). Results We included 61 studies (3,061,584 individuals). We found some medications protective against COVID-related death, including metformin, GLP-1RA and SGLT-2i. DPP-4i and insulin users were more likely to die during hospitalization. SU, TZD, and AGI were mortality neutral. Metformin use was associated with better outcome in a dose-response manner. Conclusions Metformin, GLP-1RA, and SGLT-2i were associated with lower mortality rate in patients with COVID-19 having type 2 diabetes. DPP-4i and insulin were linked to increased mortality. SU, TZD and AGI were mortality neutral. Presentation: No date and time listed
