Background. As for now, the level of C-reactive protein (CRP), which may be present in donors with traumatic and non-traumatic brain injuries, has not been reliably established, and its dynamics in patients upon the occurrence of brain death (BD) have not been studied. Objective of this study is to investigate the dynamics of CRP levels in patients with severe irreversible brain damage, which subsequently led to brain death. Material and methods. The prospective study included 106 patients with severe brain damage who were diagnosed with BD despite treatment. The CRP level was determined for patients on the 1st to 10th days of intensive therapy. Results. The CRP level upon admission to the ICU was 13.3 (3.86; 29.1) mg/l. CRP values were within normal limits only in 14 (13.2%) patients. On the 2nd day of intensive therapy, the level of CRP was higher statistically significant – 85 (45.4; 140.6) mg/l, p =0.00004 vs 1 day. On the 3rd day of intensive therapy, the level of CRP was also higher statistically significant – 135.3 (73.6; 238.2) mg/l, p =0.00001 vs 2 days. The CRP values in all patients were higher than the reference values. On the 4th day, the level of CRP in patients became 219.7 (112.7; 326.4) mg/l (p=0.00006 vs 3 days) and did not significantly change in the following days in terms of statistics. Conclusion. The dynamics of CRP levels in patients with severe brain damage can be used as a predictor of unfavorable outcome of intensive care and brain death.

Results of surgical treatment for drug-resistant temporal epilepsy and related predictors of negative post-surgery outcome

Objective: to evaluate the results of surgical treatment and identify related predictors of unfavorable outcome in patients with temporal drug-resistant epilepsy (DRE) in long-term postoperative period.Material and methods. Fifty-one patients with temporal lobe DRE were examined using clinical, neuroimaging, electro- physiological, and laboratory research methods from June 2020 to June 2023. Anteromedial temporal lobectomy (AMLE) and selective amygdalohippocampectomy (SAHE) were performed in 38 (74.5%) and 13 (25.5%) cases, respectively. Postsurgery outcomes were evaluated in 51 patients 6 months later, continued in 43 and 20 patients 1 year and 2 years, respectively, afterwards.Results. The percentage of patients with significant improvement (Engel I/II) 6 months, 1 year and 2 years post-surgery was 82.4%, 72.1%, and 55.0%, respectively. After AMLE vs. SAHE, patients had a more favorable outcome while assessing seizure control. The predictors of unfavorable post-surgery outcome included a prolonged epilepsy course before surgery, the presence of electroencephalography-verified epileptiform activity in postoperative period, and repeated surgical intervention. Patient age, the presence of focal seizures evolving into bilateral tonic-clonic seizures as well as more frequent seizures before surgery were considered as potential predictors.Conclusion. The study results show that quite high effectiveness of seizure control in postoperative period in temporal DRE is quite high that may be accounted for by probability of removing epileptogenic foci and suppression of the mechanisms ensuring emergence and irritation of epileptic discharges. Nevertheless, effectiveness of surgical treatment fades off with time, which requires to further investigate the negative factors countering long-term post-surgery effect. In connection with this, a special attention should be paid to factors such as the presence of electroencephalography-verified epileptiform activity in postoperative period, repeated surgical intervention as well as prolonged epilepsy before surgery.

Predictors of polytrauma outcome in children on the first day of treatment in ICU

The objective was to identify predictors of polytrauma outcome in children on the first day of treatment in ICU.Materials and methods. Design – multicenter, cohort, retrospective, observational study. 225 children with polytrauma were examined. The average age of children was 10 (4–14) years. There were 148 (65.8%) boys. In 65.2% of cases, the injury was received as a result of a traffic accident, catatrauma occurred in 32.6% of polytrauma. The AIS score was 34 (25–48) and the PTS score was 5 (2.0–8.0). The duration of artificial lung ventilation was 12 (0–97) hours, and treatment in ICU – 5 (2–8) days. Death was in 14.2% of cases. Results. An increase in Glasgow Coma Scale (GCS) and SpO2 by one unit (1 point, 1%) was found to reduce the risk of adverse outcome by 44% and 9%, respectively, and an increase in creatinine concentration and international normalized ratio by one unit increased the probability of patient death by 4.3 and 15.8 times, respectively. A mathematical formula was developed to assess the risk of an unfavorable outcome of polytrauma in children at the time of admission to the ICU: OR = exp (3.74–0.58 · [GCS score] – 0.09 · [SpO2] + 0.06 · [Creatinine] + 2.62 · [INR]. Its accuracy is 96.4%; sensitivity 83.4%; specificity 98.7%.Conclusion. Predictors of unfavorable outcome of polytrauma in children at admission to ICU are low scores on the Glasgow Coma Scale, severe hypoxemia, coagulopathy and kidney damage.

Factors Associated With Unfavorable Treatment Outcomes Among Persons With Pulmonary Tuberculosis: A Multicentric Prospective Cohort Study From India.

In this prospective cohort of 2006 individuals with drug-susceptible tuberculosis in India, 18% had unfavorable treatment outcomes (4.7% treatment failure, 2.5% recurrent infection, 4.1% death, 6.8% loss to follow-up) over a median 12-month follow-up period. Age, male sex, low education, nutritional status, and alcohol use were predictors of unfavorable outcomes.

Genetic Variants ε2 and ε4 of APOE Predict Mortality and Poor Outcome Independently in Spontaneous Intracerebral Hemorrhage Within the Chinese Han Population.

The heightened mortality and disability rates, coupled with restricted neurological recovery post intracerebral hemorrhage (ICH), have sparked considerable attention toward its treatment and results. Simultaneously, the influence of the APOE gene on ICH prognosis has been well-documented. This research aimed to explore the relationship between specific APOE alleles in the present cohort and the incidences of mortality, recurrence, and adverse prognosis, as determined by neurological function assessments in ICH patients. Data on patients diagnosed with ICH and hospitalized in the Department of Neurology at our institution from October 2021 to March 2022 were collected, including determining their APOE genotypes. A 1-year follow-up was conducted to evaluate mortality, ICH recurrence, and modified Rankin Scale (mRS) scores at 3 and 12 months. Poor prognosis was defined as an mRS score of ≥ 3. Initially, we analyzed the relationships between different APOE alleles and mortality, recurrence, and poor prognosis. Subsequently, we explored additional factors influencing each prognostic outcome and conducted multivariate analysis to identify independent risk factors. An analysis was conducted on 289 patients diagnosed with ICH. The presence of the ε2 allele was found to be a significant independent predictor for unfavorable outcomes at both 3 months (p = 0.022, OR = 2.138, 95% CI [2.041, 3.470]) and 1 year (p = 0.020, OR = 5.116, 95% CI [5.044, 5.307]). Moreover, the ε4 allele was established as an independent risk factor for ICH recurrence within 1 year (p = 0.025, OR = 2.326, 95% CI [1.163, 2.652]), as well as for mortality at 3 months (p = 0.037, OR = 4.250, 95% CI [4.068, 4.920]) and 1 year (p = 0.023, OR = 4.109, 95% CI [4.016, 4.739]). In conclusions, Both APOE ε2 and ε4 variants independently heighten mortality risk, recurrence, and poor prognosis after ICH. The substantial influence underscores the need for additional investigation into the impact of APOE genotype on ICH prognosis.

Postoperative seizure outcomes and antiseizure medication utilization based on histopathological diagnosis: A retrospective cohort study

ObjectiveAnalyze the association between histopathology, seizure outcomes, and drug load of antiseizure medications (ASMs) 5–8 years after epilepsy surgery to inform preoperative decision-making and consultation. MethodsIn this retrospective, non-interventional, single-center study, patients who visited the epilepsy clinic at West China Hospital, Sichuan University from Jan 1, 2015 to Dec 31, 2020 were assessed. Patients with postoperative histopathology after epilepsy resection were included and categorized into 13 etiological groups. The primary outcomes were achieving Engel class 1 at 1, 2, 3, 5, and 8 years postoperative. Secondary outcomes included the use of ASMs and comparison of postoperative seizure outcomes between adults and children. Univariate and multivariable analyses were conducted to explore the association between clinical characteristics such as histopathology and seizure outcomes. ResultsA total of 315 patients were include. Patients with embryonic dysplastic neuroepithelial tumor (DNT) achieved the best seizure outcomes (84.6 % Engel class 1). DNT (odds ratio, OR=0.103, 95 %CI=0.012–0.899), cavernous hemangiomas (OR=0.140, 95 %CI=0.024–0.819) and meningioma (OR=0.137, 95 %CI=0.021–0.910) were independently associated with a higher probability of seizure-free outcome. The results of epileptic seizures in adult and pediatric groups with different pathologies were significantly different, and the preoperative and postoperative ASM dosages were also different among adult patients with various etiologies. Additionally, multivariate analysis showed that early age at onset (adjusted hazard ratio (HR) = 1.754, 95 % CI=1.049–2.934, P=0.032), late surgical age (HR=0.569, 95 %CI=0.339–0.954, P=0.032), and longer duration from seizure onset to surgery (HR=1.735, 95 % CI=1.028–2.928, P=0.039) were independent predictors of unfavorable outcomes in epileptic seizures. Conclusionswe demonstrated that the seizure outcomes of focal epilepsy have high pathological specificity, with histopathological diagnosis serving as a crucial and independent determinant of seizure outcome. Surgical assessment should be contemplated for all patients with presumed refractory focal epilepsy, irrespective of their age.

Analysis of the course and outcomes of COVID-19 at different stages of the pandemic in hemodialysis patients

The purpose of this study was a comparative analysis of the characteristics of the course and outcomes of COVID-19 in HD patients at different stages of the pandemic, focusing on the of the use of immunomodulatory therapy.Materials and methods. The retrospective study included 897 HD patients with COVID-19 (mean age 60.7 years, M 58.5%) who were hospitalized at Moscow City Hospital № 52. Group 1 (n=720) consisted of patients infected between the end of March 2020 and April 2021, group 2 (n=177) included patients hospitalized in May-December 2021. Each of group was divided into 2 subgroups based on treatment approaches. Subgroup 1a (n=231) included patients of the initial period of the pandemic who did not receive adequate immunomodulatory therapy, while Subgroup 1b (n=489) included patients of the late stage, were treated with IL-6 receptor blockers and corticosteroids. In group 2, 108 patients in Subgroup 2a received similar therapy, while 69 patients in Subgroup 2b were treated with neutralizing monoclonal antibodies in the early stages of the disease.Results. Mortality rates in Group 1 and Group 2 was 20.1% and 14.7%, respectively (p<0.09). The incidence of unfavorable outcome was highest in Subgroup 1a and lowest in Subgroup 2b (31.2% vs 5.8%, p<0.01). Mortality in Subgroups 1b and 2a was comparable (14.9% and 20.4%), despite more severe initial lung damage according to CT data in Subgroup 2a. In these patients, immunomodulators was more frequently combined with therapeutic plasma exchange (TPE). Independent risk factors for an unfavorable outcome were the progression of pulmonary pathology, with the transformation of stages CT 1-2 to CT 3-4, and a high comorbidity index.Conclusions. The use of immunomodulatory drugs imprtoved the effectiveness of COVID-19 treatment in patients with CKD5D. In severe cases, the most favorable outcomes were achieved with a combination of immunobiological drugs, corticosteroids, and TPE. An even more significant reduction in mortality was observed following the introduction of neutralizing monoclonal antibodies into clinical practice. Independent predictors of unfavorable outcome of COVID-19 in HD patients were a high comorbidity index and the progression of CT 1-2 into CT 3-4.

Factors associated with unfavorable outcome of anterior circulation ischemic stroke following emergency endovascular therapy after complete recanalization

Objective: Endovascular thrombectomy (EVT) improves long-term patients outcomes and decreases mortality among ischemic stroke patients. However, not all patients can benefit from EVT recanalization. The present study aims to evaluate the predictors of unfavorable outcomes associated with emergency endovascular therapy despite complete recanalization. Methods: We investigated 74 eligible patients receiving EVT from January 2019 to January 2022 at a comprehensive stroke center. Demographics, clinical, radiological and treatment characteristics, safety, and functional outcomes were collected. Modified Rankin scale (mRS) score ≤ 2 at 90 days was defined as a good functional outcome. Results: A total of 111 patients were initially eligible for the study, of which 37 were excluded, resulting in 74 patients in the final study. The mean age was 69.08±12.12 years old, 67.57% patients were male, 44.59% patients with atrial fibrillation, 64.86% with hypertension, 21.62% patients with diabetes mellitus, 16.22% patients with coronary artery diseases, 6.76% with parenchymal hematoma. Median pre-EVT NIHSS (IQR) was 15.5 (12.0, 19.25). Median door-to-recanalization time (DRT) (IQR) was 208.0 (160.0,278.5) minutes and median last known norma to puncture time (LKNPT) (IQR), was 362.0 (280, 452.5) minutes. Individuals with a poorer outcome were older [73.56±9.29 vs. 65.28±13.02 years old, P=0.002], had a higher prevalence of atrial fibrillation (AF) [58.82 vs. 13%, P=0.023] and a higher National Institute of Health Stroke Scale (NIHSS) [median 16 (IQR 12.0-22.3) vs median 15 (IQR 10.0-18.0), P=0.143]. Female sex, hypertension, diabetes mellitus, coronary artery disease, and a slightly longer door-to-recanalization time were more prevalent in the unfavorable prognosis group; however, statistical analysis did not show any significant differences. Logistics binary regression model showed that older age [OR: 0.1.160 (1.011 to 1.112, P=0.031)] and AF [OR: 3.190 (1.111 to 9.164, P=0.031)] were associated with an unfavorable outcome. Conclusion: Older age, and atrial fibrillation were factors associated with the unfavorable outcome despite complete recanalization after emergency EVT of ischemic stroke.

Cerebrovascular Complications in Bacterial Meningitis

The objective is to describe a comprehensive analysis of patients with bacterial meningitis exacerbate by cerebrovascular complications. We reviewed the literature on cerebrovascular complications in adult patients with bacterial meningitis. Cerebrovascular complications occur in one fourth of patients with bacterial meningitis. The most common cerebrovascular disease complicating bacterial meningitis are cerebral infarctions (9%–25%), intracerebral hemorrhage (1%–7%), cerebral venous thrombosis (1%–10%), and subarachnoid hemorrhage (1%–5%). Streptococcus pneumoniae and Staphylococcus aureus are the primary causative pathogens leading to these complications. The pathophysiological mechanisms have not completely been elucidated but involve vasculitis, endothelial dysfunction, hypercoagulability, aggregation, and complement activation. Cerebrovascular complications are important predictors of unfavorable outcome and death, and the use of adjunctive dexamethasone has been described to reduce the incidence. In conclusion, cerebrovascular complications are common in bacterial meningitis and are strongly associated with unfavorable outcomes and death. Although our understanding of the pathophysiology is evolving, there remains a need for novel treatment strategies to address these complications.

Association of Systemic Inflammatory Response Index and Neutrophil-to-Lymphocyte Ratio on Unfavorable Functional Outcomes in Acute Ischemic Stroke Patients After Endovascular Therapy

BACKGROUNDInflammatory markers for the prognosis of acute ischemic stroke (AIS) with endovascular therapy remain unclear. The purpose of this study was to investigate the association between the Systemic Inflammatory Response Index (SIRI) and Neutrophil-to-Lymphocyte Ratio (NLR) with unfavorable functional outcomes at 90-day in individuals of AIS who underwent endovascular therapy. METHODS128 AIS patients who had endovascular therapy were enrolled from the Nanjing Stroke Registry between September 2019 and November 2022. Peripheral venous blood was collected from patients within 24 h of admission for information on the following parameters: neutrophil count, lymphocyte count, monocyte count. Then, the SIRI and NLR values were calculated, and the association among SIRI, NLR, and modified Rankin Scale (mRS) scores 90 days after endovascular therapy was examined via univariate and multivariate logistic analyses. ROC curves were utilized to determine the best threshold for SIRI and NLR in predicting negative neurological outcomes following endovascular treatment for patients with AIS. RESULTS128 participants were evaluated, among which 50% had unfavorable outcomes. Linear regression analysis showed that the best threshold for SIRI was >1.407 (OR = 1.265; 95% CI, 1.071-1.493; P = 0.006), and for NLR it was >5.347 (odds ratio; OR = 1.088; 95% confidence interval [CI], 1.007-1.175; P = 0.033). These results revealed NLR and SIRI as significant predictors of unfavorable outcomes at 90 days. The AUC for SIRI and NLR in predicting 90-day adverse outcomes was 0.643 and 0.609, respectively. CONCLUSIONSHigher SIRI and NLR levels at admission may lead to unfavorable outcomes at 90 days for AIS patients with endovascular therapy.

Evaluation of two-stage hepatectomy using portal vein embolization for colorectal liver metastasis: a retrospective nationwide cohort survey in Japan.

Two-stage hepatectomy (TSH) enables patients to undergo surgery for colorectal liver metastasis (CRLM) which one-stage hepatectomy cannot remove. Although the outcome of TSH has been reported, there is no original report from Japan. The aim of this retrospective study was to evaluate the outcome of TSH in Japanese patients with CRLM. We conducted a retrospective cohort study using the nationwide database that included clinical information of 12,519 patients treated with CRLM between 2005 and 2017 in Japan. The primary outcome measure was overall survival. The second outcome measure was progression-free survival. Fisher's exact test, chi-squared test and Mann-Whitney U test were conducted to examine an intergroup difference. Univariate and multivariate analyses were performed using Cox regression model. Survival analysis was performed by Kaplan-Meier method and log-rank test. Of the database, 53 patients undergoing TSH using portal vein embolization (PVE) were identified and analyzed. Their morbidity and in-hospital mortality rate at the second hepatectomy were 26.4% and 0.0%. The mean observation period was 21.8 months. The estimated 1-, 3- and 5-year overall survival rate were 92.5%, 70.8% and 34.7%. Multivariate analyses showed that more than 10 liver nodules significantly increased the mortality risk by 4.2-fold (95%CI 1.224-14.99, P= 0.023). Survival analysis revealed that repeat hepatectomy for disease progression after TSH was superior to chemotherapy in overall survival (mean: 49.6 vs. 18.7, months, P= 0.004). In the Japanese cohort, TSH was confirmed to be a safety procedure with acceptable survival outcome. More than 10 liver nodules may be a predictor for unfavorable outcome of patients with CRLM undergoing TSH. Furthermore, repeat hepatectomy can be a salvage treatment for resectable intrahepatic recurrence after TSH.

Predicting Role of GFAP and UCH-L1 biomarkers in Spontaneous Subarachnoid Hemorrhage: a preliminary study to evaluate in the short-term their correlation with severity of bleeding and prognosis

BackgroundSpontaneous non-traumatic subarachnoid hemorrhage (sSAH) is a severe brain vascular accident. Glial fibrillary acidic protein (GFAP) and ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) can be theoretically assayed to predict a patient’s progression, picturing different aspects of clinical failure after sSAH. The study aims to: a) explore the correlation between sSAH blood volume and biomarkers variation; b) evaluate if these can be predictive of the neurogenic response after sSAH and be prognostic of patient outcome; c) establish eventual threshold levels of biomarkers to define patients’ clinical outcome. MethodsBlood volumetry at CT scan upon admission, GFAP and UCH-L1 were collected at 24 h, at 72 h, and after 7 days from hemorrhage. Trends and cut-off serum sampling were determined. Clinical outcome was assessed with mRS scale at 14 days. ResultsA strong correlation between GFAP and UCH-L1 and blood diffusion volume in all explored serum intervals related to unfavorable outcome. GFAP and UCH-L1 were very early predictors of unfavorable outcomes at 24 h from sSAH (p = 0.002 and 0.011 respectively). Threshold levels of UCH-L1 apparently revealed a very early, early and late predictor of unfavorable outcomes. ConclusionGFAP and UCH-L1 represent a potential tool for prompt monitoring and customization of therapies in neurosurgical patients.

Hospital challenges faced by frail patients with ovarian cancer and the adverse outcomes: A nationwide study.

5572 Background: Ovarian cancer is a leading cause of gynecological cancer-related deaths and one of the most common causes of cancer-related fatalities among women. Frailty has been identified as a predictor of unfavorable outcomes for cancer patients, but there is limited research on its impact on individuals with ovarian cancer. We examined the effects of Frailty in hospitalized ovarian cancer patients and the associated outcomes. Methods: National Inpatient Sample (NIS) 2020 was used to identify the patients with a primary diagnosis of ovarian cancer (local/regional and advanced metastatic) and was stratified into patients with and without Frailty. The primary outcome was mortality, and secondary outcomes included length of stay, the total cost of hospitalization, and other in-hospital adverse outcomes. Multivariate logistic regression analysis was used to calculate the outcomes after adjusting for confounding variables. Results: A total of 19790 patients were hospitalized with a primary diagnosis of Ovarian cancer, among which 3215 (16.24%) patients had the concurrent diagnosis of Frailty. The mean age of patients with and without Frailty was 65.76 (+/-13.10) and 60 (+/-14.45),p<0.001, respectively. After adjusting for confounding variables, Frailty was associated with an increased risk of mortality in patients with ovarian cancer (OR=3.01(1.83-4.95); p<0.001). Patients with Frailty were also at risk of increased length of stay (+3.80 Days (3.09-4.50; p<0.001) and total cost of hospitalization (+ $ 34662 (22973-46351); p<0.001). Frail patients also had an increased likelihood of Acute respiratory failure (OR=1.72 (1.22-2.42); p=0.002), Acute kidney injury (OR=2.40 (1.88-3.05); p<0.001), Sepsis (OR=4.97 (3.19-7.75); p<0.001), ICU admission (OR=2.23 (1.44-3.45); p<0.001), Pneumonia (OR=2.63 (1.69-4.10); p<0.001), total parenteral nutrition (OR=14.20 (7.80-25.83); p<0.001) and Intubation (OR=2.11 (1.21-3.69); p=0.008). However, there was no difference in the risk of noninvasive mechanical ventilation (OR=2.07 (0.95-4.52); p=0.48) or enteral feeding (OR=32.73 (0.63-1696); p=0.08). Conclusions: Frailty in ovarian cancer patients is considered an independent predictor of mortality. It is also associated with increased healthcare resource utilization and adverse in-hospital outcomes.[Table: see text]

The impact of comorbidities on prolonged mechanical ventilation in patients with chronic obstructive pulmonary disease

BackgroundIn patients with chronic obstructive pulmonary disease (COPD) and acute respiratory failure, approximately 10% of them are considered to be at high risk for prolonged mechanical ventilation (PMV, > 21 days). PMV have been identified as independent predictors of unfavorable outcomes. Our previous study revealed that patients aged 70 years older and COPD severity were at a significantly higher risk for PMV. We aimed to analyze the impact of comorbidities and their associated risks in patients with COPD who require PMV.MethodsThe data used in this study was collected from Kaohsiung Medical University Hospital Research Database. The COPD subjects were the patients first diagnosed COPD (index date) between January 1, 2012 and December 31, 2020. The exclusion criteria were the patients with age less than 40 years, PMV before the index date or incomplete records. COPD and non-COPD patients, matched controls were used by applying the propensity score matching method.ResultsThere are 3,744 eligible patients with COPD in the study group. The study group had a rate of 1.6% (60 cases) patients with PMV. The adjusted HR of PMV was 2.21 (95% CI 1.44–3.40; P < 0.001) in the COPD patients than in non-COPD patients. Increased risks of PMV were found significantly for patients with diabetes mellitus (aHR 4.66; P < 0.001), hypertension (aHR 3.20; P = 0.004), dyslipidemia (aHR 3.02; P = 0.015), congestive heart failure (aHR 6.44; P < 0.001), coronary artery disease (aHR 3.11; P = 0.014), stroke (aHR 6.37; P < 0.001), chronic kidney disease (aHR 5.81 P < 0.001) and Dementia (aHR 5.78; P < 0.001).ConclusionsAge, gender, and comorbidities were identified as significantly higher risk factors for PMV occurrence in the COPD patients compared to the non-COPD patients. Beyond age, comorbidities also play a crucial role in PMV in COPD.

Constitutive type-1 interferons signaling activity in malignant gliomas.

Recent studies revealed a pro-tumor effect of constitutive Type-1 interferons (IFN-I) production and the downstream signaling activity in several malignancies. In contrast, heterogeneity and clinical significance of the signaling activity in gliomas remain unknown. Thus, we aimed to depict the heterogeneity and clinical significance of constitutive Type-1 interferon (IFN-I) production and the downstream signaling activity in gliomas. We utilized multiplex immunofluorescence (mIF) on a 364 gliomas tissue microarray from our cohort. Moreover, we conducted bioinformatic analyses on the Cancer Genome Atlas (TCGA) and the Chinese Glioma Genome Atlas (CGGA) databases to investigate the heterogeneity and clinical significance of constitutive IFN-I signaling activity in gliomas. We observed high heterogeneity of the constitutive IFN-I signaling activity among glioma subtypes. Signaling increased with the WHO malignancy grade while decreasing in the gliomas with IDH mutations. Additionally, high IFN-I activity served as an independent predictor of unfavorable outcomes, and global DNA hypermethylation in IDH-mutant gliomas was associated with decreased IFN-I signaling activity. Positive correlations were observed between the IFN-I activity and glioma-associated inflammation, encompassing both anti-tumor and pro-tumor immune responses. Furthermore, the IFN-I activity varied significantly among tumor and immune cells in the glioma microenvironment (GME). Notably, a distinct pattern of IFN-I signaling activity distribution in GME cells was observed among glioma subtypes, and the pattern was independently associated with patient overall survival. Constitutive IFN-I signaling activity varies significantly among glioma subtypes and represents a potential indicator for increased glioma inflammation and unfavorable clinical outcomes.

Shock Index is a Stronger Predictor of Outcomes in Older Compared to Younger Patients

IntroductionThe shock index (SI) is a known predictor of unfavorable outcomes in trauma. This study seeks to examine and compare the SI values between geriatric patients and younger adults. MethodsWe conducted a retrospective study of the Trauma Quality Improvement Program database from 2017 to 2019. All patients≥ 25 y with injury severity score ≥ 16 were included. Age groups were defined as 25-44 y (group A), 45-64 y (group B), and ≥65 y (group C). SI was calculated for all patients. The primary outcome was mortality and secondary outcomes were need for blood transfusion and need for major surgical intervention (consisting angiography, exploratory laparotomy, and thoracotomy). ResultsA total of 244,943 patients were studied. The SI was highest in group A (0.82 ± 0.33) and lowest in group C (0.62 ± 0.30) (P < 0.001). Mortality rate of group C (17%) was significantly higher than group A (9.7%) and B (11.3%) (P < 0.001). In group A, each 0.1 increase in SI was associated with mortality (odds ratio [OR] = 1.079), need for blood transfusion (OR = 1.225) and need for major surgical intervention (OR = 1.347) (P < 0.001 for all). In group C, each 0.1 increase in SI was associated with mortality (OR = 1.126), need for blood transfusion (OR = 1.318), and need for major surgical intervention (OR = 1.648) (P < 0.001 for all). The area under the curve of SI was significantly higher in group C compared to other groups for needing a major surgical intervention and need for blood transfusion (P < 0.05 for both). ConclusionsThese results highlight the significance of the SI as a valuable indicator in geriatric patients with severe trauma. The findings show that SI predicts outcomes in geriatrics more strongly than in younger counterparts.

Review of the Diagnostic and Prognostic Values of Cardiac Markers in Diabetes

Abstract Introduction Cardiovascular disease is a leading cause of mortality in people with diabetes (PWD). We aimed to explore the role of troponin T (TnT) and probrain natriuretic peptide (proBNP) as screening and prognostic indicators of cardiovascular morbidity and mortality in PWD in the existing literature. Methods This review paper is a focused narrative nonsystematic review of the literature which examined relevant publications pertinent to the significance of cardiac biomarkers. We aimed to investigate the diagnostic value of cardiac TnT (cTnT) and cTnI in addition to proBNP in diabetes and the prognostic value of cTnT and proBNP in diabetic and nondiabetic patients. The process of searching through literature was conducted from December 2022 to April 2023. Searches were done across PubMed and Google Scholar databases to identify relevant articles published from January 2001 to April 2023. The selected were entered into EndNote 20 software to extract the title and abstract. Results A total of 75 articles were identified in Google Scholar in addition to 32 articles from PubMed. After a thorough review, only a total of 22 articles were selected, pointing out those which discussed the pathophysiology and diagnostic, prognostic, and screening values of the types of Tn and proBNP markers. The value of TnT in PWD, specifically T2D, is threefold higher than in healthy patients. Individuals with high levels of high-sensitivity (hs) cTnI or cTnT were at the highest mortality risk. Nonetheless, N-terminal (NT)-proBNP and TnT function independently as predictors of unfavorable outcomes. Conclusions TnT is an important early screening tool prognostic indicator. Elevated TnT was associated with an increased risk of cardiovascular events in PWD. hs-cTn may help diabetes-related clinical care for older persons by identifying those at high mortality risk; furthermore, in diabetic individuals, NT-pro-BNP appears to be 92% sensitive and 90% specific for the diagnosis of heart failure.

Diabetes-associated factors in hospitalized COVID-19 patients with concomitant type 2 diabetes mellitus: focus on mean in-hospital glycemic values

Aim of the study: to evaluate the significance of mean glycemic values during hospitalization as a potentially important diabetes-associated risk factor of unfavorable outcomes in inpatients with COVID-19 and type 2 diabetes mellitus (T2DM).Materials and methods. 139 patients with COVID-19 were observed in the hospital, 42 of them had concomitant type 2 diabetes mellitus (DM2). In patients with COVID-19 and type 2 diabetes, the relationship between mean glycemic values during hospitalization and adverse outcomes (death and/or transfer of the patient to the intensive care unit (ICU)) was assessed. The average number of tests to assess glycemia in the hospital was 38.4 ± 15.68 per patient.Results and discussion. According to correlation analysis data, an increase in mean in-hospital glycemia correlated with the severity of lung damage by computed tomography (R = 0.54, p = 0.002), the need for respiratory support by SMRT-CO score (R = 0.29, p = 0.070) and hypercoagulation by the international normalized ratio (R= –0.42, p=0.008). According to regression analysis, predictors of unfavorable outcomes included mean in-hospital glycemia (OR 1.4 [0.93; 2.12], p=0.073) and the percentage of tests with hypoglycemia in the hospital (OR 2.09 [0.89; 5 .40], p=0.016) as well as a history of diabetes (OR 5.5 [0.95, 31.60], p=0.029).Conclusion. Impaired glycemic control during the whole hospitalization period negatively affects disease severity and the risk of adverse outcomes in patients with COVID-19 and type 2 diabetes.

Performance of several clinical scoring systems as predictors of adverse outcomes in acute exposure to toxic alcohols.

Toxic alcohols are chemicals with common metabolic characteristics resulting in severe morbidities and mortalities. The current study aimed to assess the efficacy of six scoring systems: The Poison Severity Score (PSS), Acute Physiology and Chronic Health Evaluation (APACHE) II score, Sequential Organ Failure Assessment (SOFA) score, Rapid Acute Physiology Score (RAPS), Rapid Emergency Medicine Score (REMS), and Modified Early Warning Score (MEWS) in stratifying the patients exposed to toxic alcohol based on liability of organ failure, prolonged hospital stay, and need for an antidote. A seven-year retrospective cross-sectional study was conducted using medical records of adult patients admitted to a poison control center. About 42.6% were complicated with adverse outcomes. Methanol was the worst toxic alcohol and the only cause of blindness and death. About 27.1% of methanol-exposed patients suffered from acute kidney injury, 15.3% suffered from hemodynamic instability and neurological dysfunction, and 8.5% suffered from respiratory failure. An APACHE II score above 8 was the best predictor of unfavorable outcomes, exhibiting the highest area under the curve (0.972), followed by the SOFA score. The APACHE II score was praised for being the best discriminator of an expected prolonged hospital stay. Yet, the simple scores, including RAPS and REMS, showed good performance as unfavorable outcome predictors with no significant variations to PSS, APACHE II score, and SOFA scores. The current study concluded that though the APACHE II and SOFA scores were superior to others, the RAPS and REMS are good, simple, and effective alternatives, particularly when resources are restricted.
