The Impact

The impact of dehydration at admission of patients with spontaneous intracerebral hemorrhage (ICH) on short-term mortality remains ambiguous due to scarce data. All of the consecutive patients with spontaneous ICH, who were referred to our neurovascular center in 2018/19, were assessed for hydration status on admission. Dehydration was defined by a blood urea-to-creatinine ratio > 80. In a cohort of 249 patients, 76 patients (31%) were dehydrated at the time of admission. The following factors were significantly and independently associated with increased 30-day mortality in multivariate analysis: “signs of cerebral herniation” (p = 0.008), “initial midline shift > 5 mm” (p < 0.001), “ICH score > 3” (p = 0.007), and “admission dehydration status” (p = 0.007). The results of the present study suggest that an admission dehydration status might constitute a significant and independent predictor of short-term mortality in patients with spontaneous ICH.

Hba1c Levels

Background: The relationship between glycosylated hemoglobin (HbA1c) and prognosis of spontaneous intracerebral hemorrhage (SICH) patients has not been fully elucidated. This study aimed to reveal the relationship between HbA1c levels and short-term mortality after patient admission with SICH.Methods: It was a large-scale, multicenter, cross-sectional study. From August 1, 2015, to July 31, 2019, a total of 41910 SICH patients were included in the study from the Chinese Stroke Center Alliance (CSCA) program. Finally, we comprehensively analyzed the data from 21,116 patients with SICH. HbA1c was categorized into four groups by quartile. Univariate and multivariate logistic regression analyses were used to assess the association between HbA1c levels and short-term mortality in SICH patients.Results: The average age of the 21,116 patients was 62.8 ± 13.2 years; 13,052 (61.8%) of them were male, and 507 (2.4%) of them died. Compared to the higher three quartiles of HbA1c, the lowest quartile (≤5.10%) had higher short-term mortality. In subgroup analysis with or without diabetes mellitus (DM) patients, the mortality of the Q3 group at 5.60–6.10% was significantly lower than that of the Q1 group at ≤5.10%. After adjustment for potential influencing factors, the ROC curve of HbA1c can better predict the short-term mortality of patients with SICH (AUC = 0.6286 P &lt; 0.001).Conclusions: Therefore, we concluded that low or extremely low HbA1c levels (≤5.10%) after stroke were associated with higher short-term mortality in SICH patients, with or without DM.

Objective: Providing melatonin in animal models with spontaneous intracerebral hemorrhage (SIH) has been associated with beneficial effects. However, to our knowledge, there are no published data on circulating melatonin levels regarding the prognosis of SIH patients. Therefore, the objectives of this study were to determine whether serum melatonin levels in SIH patients were associated with early mortality and whether they could be used as prognostic biomarkers. Methods: This observational and prospective study included patients with supratentorial and clinically severe SIH (defined as Glasgow Coma Scale GCS <9) admitted to the Intensive Care Units of six Spanish hospitals. Serum melatonin levels were determined at the time of severe SIH diagnosis. Mortality at 30 days was the study end-point. Results: Non-surviving patients (n = 46) showed higher serum melatonin levels (p < 0.001) than surviving (n = 54) patients. An area under the curve was found for the prediction of 30-day mortality by serum melatonin levels of 0.89 (95% CI = 0.81–0.94; p < 0.001). Multiple logistic regression analysis showed an association of serum melatonin levels with 30-day mortality (Odds Ratio = 8.16; 95% CI = 2.30–28.95; p = 0.001) after controlling for midline shift, glycemia, early evacuation of SIH, and Intracerebral hemorrhage(ICH) score. Conclusions: The novel findings by our study were the presence of higher serum melatonin levels in non-surviving patients than in surviving patients and the association of these levels with mortality.

The Impact

Introduction: Spontaneous intracerebral hemorrhage (ICH) is associated with a high morbidity and mortality rate despite current medical management. The benefits of open surgical evacuation for ICH remain controversial. Here we present initial results of the effectiveness of stereotactic image-guided endoscopic evacuation of ICH. Methods: Over 9-years, 41 patients with ICH (age 65+−14 years, 66% male, average admission GCS 10 & ICH Score 2, 46% with concurrent intraventricular hemorrhage) were treated. The current technique, which evolved from using direct endoscopic visualization, uses frameless stereotactic guidance alone to aspirate at two specified locations within the hematoma. An endoscope sheath is introduced through a bur hole into the hematoma along its long axis. Suction is applied to the sheath, without endoscopic viewing, at two locations, 1/3 and 2/3 of the way through the long-axis of the ICH. Endoscopic visualization of the cavity is then performed to ensure hemostasis. ICH volume was calculated using pre- and postoperative CT measurements ((length x width x height)/2). Results: Pre- and postoperative ICH volumes averaged 56.5 and 15.9cc, respectively, a reduction of 67.6+−41.9% (p<0.0001) with greater than 50% reduction in 78% of patients. Within 30 days, two patients (5%) developed rebleeding, one with acutely increased hematoma volume on postop CT. Average preop modified Rankin Score (mRS) decreased from 4.4 to 4.1 at follow-up (p=0.17). Seven-day and 30-day mortality occurred in 5 (12%) and 1 (2.4%) patients, respectively. This 30-day mortality compares favorably with the predicted rate of 26% based on average ICH score of 2 for the series. There were 2 surgical complications including ipsilateral ischemic stroke and subdural hematoma. Comparing the current aspiration technique to the previous technique, there were trends towards greater average reduction in hematoma volume (81.7% versus 58.5%, respectively, p=0.08) and greater improvement in clinical outcome (average mRS improvement 0.75 points versus 0 points, respectively, p=0.08). Conclusions: Image-guided endoscopic evacuation is a minimally-invasive approach to reduce ICH volume. Greater than 50% reduction in hematoma volume was achieved in the large majority of patients. Further study is required to evaluate the impact of endoscopic ICH evacuation on clinical outcomes compared to other treatments.

AbstractThe association between early glycemic change and short-term mortality in non-diabetic patients with acute intracerebral hemorrhage (ICH) is unclear. We retrospectively investigated non-diabetic patients with lobar (n = 262) and non-lobar ICH (n = 370). Each patient had a random serum glucose test on hospital admission and a fasting serum glucose test within the following 48 h. Hyperglycemia was defined as serum glucose ≥ 7.8 mmol/l. Four patterns were determined: no hyperglycemia (reference category), persistent hyperglycemia, delayed hyperglycemia, and decreasing hyperglycemia. Associations with 30-day mortality were estimated using Cox models adjusted for major features of ICH severity. Persistent hyperglycemia was associated with 30-day mortality in both lobar (HR 3.00; 95% CI 1.28–7.02) and non-lobar ICH (HR 4.95; 95% CI 2.20–11.09). In lobar ICH, 30-day mortality was also associated with delayed (HR 4.10; 95% CI 1.77–9.49) and decreasing hyperglycemia (HR 2.01, 95% CI 1.09–3.70). These findings were confirmed in Cox models using glycemic change (fasting minus random serum glucose) as a continuous variable. Our study shows that, in non-diabetic patients with ICH, early persistent hyperglycemia is an independent predictor of short-term mortality regardless of hematoma location. Moreover, in non-diabetic patients with lobar ICH, both a positive and a negative glycemic change are associated with short-term mortality.

Spontaneous intracerebral hemorrhage (SICH) has been common in China with high morbidity and mortality rates. This study aims to develop a machine learning (ML)-based predictive model for the 90-day evaluation after SICH. We retrospectively reviewed 751 patients with SICH diagnosis and analyzed clinical, radiographic, and laboratory data. A modified Rankin scale (mRS) of 0–2 was defined as a favorable functional outcome, while an mRS of 3–6 was defined as an unfavorable functional outcome. We evaluated 90-day functional outcome and mortality to develop six ML-based predictive models and compared their efficacy with a traditional risk stratification scale, the intracerebral hemorrhage (ICH) score. The predictive performance was evaluated by the areas under the receiver operating characteristic curves (AUC). A total of 553 patients (73.6%) reached the functional outcome at the 3rd month, with the 90-day mortality rate of 10.2%. Logistic regression (LR) and logistic regression CV (LRCV) showed the best predictive performance for functional outcome (AUC = 0.890 and 0.887, respectively), and category boosting presented the best predictive performance for the mortality (AUC = 0.841). Therefore, ML might be of potential assistance in the prediction of the prognosis of SICH.

Death Count

We introduce a new method for making short-term mortality forecasts of a few months, illustrating it by estimating how many deaths might have happened if some major shock had not occurred. We apply the method to assess excess mortality from March to June 2020 in Denmark and Sweden as a result of the first wave of the coronavirus pandemic, associated policy interventions and behavioral, healthcare, social and economic changes. We chose to compare Denmark and Sweden because reliable data were available and because the two countries are similar but chose different responses to covid-19: Denmark imposed a rather severe lockdown; Sweden did not. We make forecasts by age and sex to predict expected deaths if covid-19 had not struck. Subtracting these forecasts from observed deaths gives the excess death count. Excess deaths were lower in Denmark than Sweden during the first wave of the pandemic. The later/earlier ratio we propose for shortcasting is easy to understand, requires less data than more elaborate approaches, and may be useful in many countries in making both predictions about the future and the past to study the impact on mortality of coronavirus and other epidemics. In the application to Denmark and Sweden, prediction intervals are narrower and bias is less than when forecasts are based on averages of the last five years, as is often done. More generally, later/earlier ratios may prove useful in short-term forecasting of illnesses and births as well as economic and other activity that varies seasonally or periodically.

ABSTRACT ObjectivesTo assess the impact of late presentation (CD4 cell count <200 cells/μl at presentation) for care and treatment on short-term mortality (death within a year of presentation) among HIV-infected adults in rural South Africa. ApproachWe applied deterministic and probabilistic record linkage approaches to link adult patients seeking care and treatment for HIV from a health facility between 2007 and 2013 to population under continuous surveillance by the Agincourt Health and Demographic Surveillance System (HDSS) in rural northeast South Africa. The resulting record-linked dataset was thereafter analysed to estimate short-term mortality (death within a year of presentation) differences in late presenters (initial presentation at health facility with CD4 cell count less than 200 cells/μl) and early presenters (presentation with CD4 cell count of 200 or more cells/μl). In the linked dataset, CD4 cell count was extracted from the health facility database where as date of death came from the HDSS database. ResultsA total of 3,553 patients who sought care and treatment for HIV at Bhubhezi clinic between 2007 and 2013 were linked to the Agincourt HDSS surveillance population. Proportion of patients classified as late presenters was 60.9%. Short-term mortality was 8.9% (317/3,553): 11.1% among those who presented late and 5.5 % among those who presented early (P<0.001). ConclusionRecord linkage facilitated the assessment of the impact of late presentation for care and treatment on short-term mortality among HIV-infected adults in rural South Africa. In the population studied, late presentation is high and is contributing to high mortality among people living with HIV. Strategies that would facilitate early presentation are needed in order to reduce mortality among people living with HIV.

Undetermined Etiology

Objective: We sought to determine the prevalence, radiological characteristics, and clinical outcomes of intracerebral hemorrhage (ICH) of undetermined etiology. Methods: Systematic review and meta-analysis of studies involving patients with spontaneous ICH was conducted to assess the prevalence and clinical-radiological characteristics of undetermined ICH. Additionally, we assessed the rates for ICH secondary to hypertensive arteriopathy (HTN-A) and cerebral amyloid angiopathy (CAA). Subgroup analyses were performed based on the use of a) etiology-oriented ICH classification, b) detailed neuroimaging, and c) Boston criteria among CAA-ICH. Results: 24 studies were included (n=15,828; mean age: 64.8 years, males: 60.8%). The pooled prevalence of HTN-A ICH, undetermined ICH and CAA-ICH were 50% (95%CI: 43-58%), 18% (95%CI: 13-23%), and 12% (95%CI: 7-17%; p<0.001 between subgroups). The volume of ICH was largest in CAA-ICH 24.7mL (95%CI: 19.7-29.8mL), followed by HTN-A ICH 16.2mL (95%CI: 10.9-21.5mL) and undetermined ICH 15.4mL (95%CI: 6.2-24.5mL). Among patients with undetermined ICH, the rates of short-term mortality and intraventricular hemorrhage were 33% (95%CI: 25-42%) and 38% (95%CI: 28-48%), respectively. Subgroup analysis demonstrated a higher rate of undetermined ICH among studies that did not use an etiology-oriented classification (22%; 95%CI: 15-29%). No difference was observed between studies based on the completion of detailed neuroimaging to assess the rates of undetermined ICH (p=0.62). Conclusions: The etiology of spontaneous ICH remains undetermined among one in five patients in studies using etiology-oriented classification and among one in four patients in studies that avoid using etiology-oriented classification. The short-term mortality in undetermined ICH is high despite the relatively small ICH volume. Our findings suggest the use of etiology-oriented classification to approach ICH patients (Figure).
