Acute evacuation of 54 intracerebral hematomas (aICH) during the microsurgical clipping of a ruptured middle cerebral artery bifurcation aneurysm-illustration of the individual clinical courses and outcomes with a serial brain CT/MRI panel until 12 months.

PURPOSE: In aneurysmal intracerebral hemorrhage (aICH), our review showed the lack of the patient's individual (i) timeline panels and (ii) serial brain CT/MRI slice panels through the aICH evacuation and neurointensive care until the final brain tissue outcome. METHODS: Our retrospective cohort consists of 54 consecutive aICH patients from a defined population who acutely underwent the clipping of a middle cerebral artery bifurcation saccular aneurysm (Mbif sIA) with the aICH evacuation at Kuopio University Hospital (KUH) from 2010 to 2019. We constructed the patient's individual timeline panels since the emergency call and serial brain CT/MRI slice panels through the aICH evacuation and neurointensive care until the final brain tissue outcome. The patients were indicated by numbers (1.-54.) in the pseudonymized panels, tables, results, and discussion. RESULTS: The aICH volumes on KUH admission (median 46 cm3) plotted against the time from the emergency call to the evacuation (median 8 hours) associated significantly with the rebleeds (n=25) and the deaths (n=12). The serial CT/MRI slice panels illustrated the aICHs, intraventricular hemorrhages (aIVHs), residuals after the aICH evacuations, perihematomal edema (PHE), delayed cerebral injury (DCI), and in the 42 survivors, the clinical outcome (mRS) and the brain tissue outcome. CONCLUSIONS: Regarding aICH evacuations, serial brain CT/MRI panels present more information than words, figures, and graphs. Re-bleeds associated with larger aICH volumes and worse outcomes. Swift logistics until the sIA occlusion with aICH evacuation is required, also in duty hours and weekends. Intraoperative CT is needed to illustrate the degree of aICH evacuation. PHE may evoke uncontrollable intracranial pressure (ICP) in spite of the acute aICH volume reduction.

Prevalence of pre-eclampsia in 265 patients with an intracranial aneurysm, 393 female relatives versus a control cohort: A case-control study.

BACKGROUND AND OBJECTIVES: There is emerging evidence on the connection between pre-eclampsia and saccular intracranial aneurysms (sIAs). Our aim was to study the prevalence of pre-eclampsia in sIA patients, their female relatives, and matched controls, and to examine familial sIA disease and familial pre-eclampsia in sIA patients' families. METHODS: We included all female sIA patients in the Kuopio Intracranial Aneurysm Patient and Family Database from 1995 to 2018. First, we identified the sIA patients, their female relatives, and matched population controls with the first birth in 1987 or later and studied the prevalence of pre-eclampsia. Second, all female sIA patients and all female relatives were analyzed for familial sIA disease and familial pre-eclampsia. Using the Finnish nationwide health registries, we obtained data on drug purchases, hospital diagnoses, and causes of death. RESULTS: In total, 265 sIA patients, 57 daughters, 167 sisters, 169 nieces, and 546 matched controls had the first birth in 1987 or later. Among them, 29 (11%) sIA patients, 5 (9%) daughters, 10 (6%) sisters, 10 (6%) nieces, and 32 (6%) controls had pre-eclampsia. Of all the 1895 female sIA patients and 12,141 female relatives, 68 sIA patients and 375 relatives had pre-eclampsia, including 32 families with familial pre-eclampsia. CONCLUSIONS: Pre-eclampsia was significantly more common in the sIA patients than in their matched controls. Familial sIA disease and familial pre-eclampsia co-occurred in seven families. Further studies of the mechanisms by which pre-eclampsia could affect the walls of brain arteries and increase the rupture risk in sIA disease are indicated.

Long-term Risk of Epilepsy in Subarachnoid Hemorrhage Survivors With Positive Family History: A Population-Based Follow-up Study.

BACKGROUND AND OBJECTIVES: Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating form of stroke affecting the working-age population, where epilepsy is a common complication and major prognostic factor for increased morbidity in aSAH survivors. The objective of this analysis was to assess whether epilepsy in first-degree relatives is a risk of developing epilepsy after aSAH. METHODS: We used a region-specific database that includes all cases of unruptured and ruptured saccular intracranial aneurysm admitted to Kuopio University Hospital from its defined Eastern Finnish catchment population. We also retrieved data from Finnish national health registries for prescription drug purchases and reimbursement, hospital discharge, and cause of death and linked them to patients with aSAH, their first-degree relatives, and population controls matched 3:1 by age, sex, and birth municipality. Cox regression modeling and Kaplan-Meier survival curves were used for analysis. RESULTS: We examined data for 760 consecutive 12-month survivors of aSAH, born in 1950 or after, with a first aSAH from January 1, 1995, to December 31, 2018. Of the 760 patients (median age, 47 years; 53% female; median follow-up, 11 years), 111 (15%) developed epilepsy at a median of 7 months (interquartile range, 2-14 months) after admission for aSAH. Of the 2,240 population controls and 4,653 first-degree relatives of patients with aSAH, 23 (0.9%) and 80 (1.7%), respectively, developed epilepsy during the follow-up period. Among 79 patients with epilepsy in first-degree relatives, 22 (28%) developed epilepsy after aSAH; by contrast, among 683 patients with no epilepsy in first-degree relatives, 89 (13%) developed epilepsy after aSAH. Having at least 1 relative with epilepsy was an independent risk factor of epilepsy after aSAH (hazard ratio, 2.44; 95% CI 1.51-3.95). Cumulative 1-year rates by first-degree relationship were 40% with 1 or more children with epilepsy, 38% with 1 or more affected parents, 5% with 1 or more affected siblings, and 10% with no relatives with epilepsy. DISCUSSION: Patients who developed epilepsy after aSAH were significantly more likely to have first-degree relatives with epilepsy than those who did not develop epilepsy after the aSAH.

Should individual timeline and serial CT/MRI panels of all patients be presented in acute brain insult cohorts? A pilot study of 45 patients with decompressive craniectomy after aneurysmal subarachnoid hemorrhage.

PURPOSE: Our review of acute brain insult articles indicated that the patients' individual (i) timeline panels with the defined time points since the emergency call and (ii) serial brain CT/MRI slice panels through the neurointensive care until death or final brain tissue outcome at 12 months or later are not presented. METHODS: We retrospectively constructed such panels for the 45 aneurysmal subarachnoid hemorrhage (aSAH) patients with a secondary decompressive craniectomy (DC) after the acute admission to neurointensive care at Kuopio University Hospital (KUH) from a defined population from 2005 to 2018. The patients were indicated by numbers (1.-45.) in the pseudonymized panels, tables, results, and discussion. The timelines contained up to ten defined time points on a logarithmic time axis until death ([Formula: see text]; 56%) or 3 years ([Formula: see text]; 44%). The brain CT/MRI panels contained a representative slice from the following time points: SAH diagnosis, after aneurysm closure, after DC, at about 12 months (20 survivors). RESULTS: The timelines indicated re-bleeds and allowed to compare the times elapsed between any two time points, in terms of workflow swiftness. The serial CT/MRI slices illustrated the presence and course of intracerebral hemorrhage (ICH), perihematomal edema, intraventricular hemorrhage (IVH), hydrocephalus, delayed brain injury, and, in the 20 (44%) survivors, the brain tissue outcome. CONCLUSIONS: The pseudonymized timeline panels and serial brain imaging panels, indicating the patients by numbers, allowed the presentation and comparison of individual clinical courses. An obvious application would be the quality control in acute or elective medicine for timely and equal access to clinical care.

Metabolomics of Synovial Fluid and Infrapatellar Fat Pad in Patients with Osteoarthritis or Rheumatoid Arthritis.

Osteoarthritis (OA) and autoimmune-driven rheumatoid arthritis (RA) are inflammatory joint diseases with complex and insufficiently understood pathogeneses. Our objective was to characterize the metabolic fingerprints of synovial fluid (SF) and its adjacent infrapatellar fat pad (IFP) obtained during the same surgical operation from OA and RA knees. Non-targeted metabolite profiling was performed for 5 non-inflammatory trauma controls, 10 primary OA (pOA) patients, and 10 seropositive RA patients with high-resolution mass spectrometry-based techniques, and metabolites were matched with known metabolite identities. Groupwise differences in metabolic features were analyzed with the univariate Welch's t-test and the multivariate linear discriminant analysis (LDA) and principal component analysis (PCA). Significant discrimination of metabolite profiles was discovered by LDA for both SF and IFP and by PCA for SF based on diagnosis. In addition to a few drug-derived substances, there were 16 and 13 identified metabolites with significant differences between the diagnoses in SF and IFP, respectively. The pathways downregulated in RA included androgen, bile acid, amino acid, and histamine metabolism, and those upregulated included biotin metabolism in pOA and purine metabolism in RA and pOA. The RA-induced downregulation of androgen and bile acid metabolism was observed for both SF and IFP. The levels of 11 lipid metabolites, mostly glycerophospholipids and fatty acid amides, were also altered by these inflammatory conditions. The identified metabolic pathways could be utilized in the future to deepen our understanding of the pathogeneses of OA and RA and to develop not only biomarkers for their early diagnosis but also therapeutic targets.

Pre-eclampsia, gestational diabetes and hypertensive disorders in patients with intracranial aneurysms: A case-control study.

BACKGROUND AND PURPOSE: The aim of this study was to define the prevalence of pre-eclampsia, gestational hypertension (HT), chronic HT, and gestational diabetes during pregnancy in a defined population of patients with saccular intracranial aneurysms (sIAs). METHODS: We included all patients with sIA, first admitted to the Neurosurgery Department of Kuopio University Hospital from its defined catchment population between 1990 and 2015, who had given birth for the first time in 1990 or later. The patients' medical records were reviewed, and clinical data were linked with prescription drug usage, hospital diagnoses and causes of death, obtained from nationwide registries. The prevalences of pre-eclampsia, other hypertensive disorders and gestational diabetes in patients were compared with a matched control population (n = 324). In addition, the characteristics of sIA disease in patients with pre-eclampsia were compared to those of sIA patients without pre-eclampsia. RESULTS: A total of 169 patients with sIA fulfilled the inclusion criteria. Of these, 22 (13%) had pre-eclampsia and 32 (19%) had other hypertensive disorders during pregnancy. In 324 matched controls who had given birth, the prevalence of pre-eclampsia was 5% (n = 15) and other hypertensive disorders were diagnosed in 10% (n = 34). There was no significant difference in prevalence of gestational diabetes (12% vs. 11%). Patients with sIA with pre-eclampsia more frequently had irregularly shaped aneurysms (p = 0·003). CONCLUSIONS: Pre-eclampsia was significantly more frequent in patients with sIA than in their population controls. Irregularly shaped aneurysms were more frequent in sIA patients with pre-eclampsia. Further studies are required to determine whether history of pre-eclampsia may indicate an elevated risk for sIA formation or rupture.

Clinical condition of 120 patients alive at 3 years after poor-grade aneurysmal subarachnoid hemorrhage.

BACKGROUND: To study the clinical condition of poor-grade aneurysmal subarachnoid hemorrhage (aSAH) patients alive at 3 years after neurointensive care. METHODS: Of the 769 consecutive aSAH patients from a defined population (2005-2015), 269 (35%) were in poor condition on admission: 145 (54%) with H&H 4 and 124 (46%) with H&H 5. Their clinical lifelines were re-constructed from the Kuopio Intracranial Aneurysm Database and Finnish nationwide registries. Of the 269 patients, 155 (58%) were alive at 14 days, 125 (46%) at 12 months, and 120 (45%) at 3 years. RESULTS: The 120 H&H 4-5 patients alive at 3 years form the final study population. On admission, 73% had H&H 4 but only 27% H&H 5, 59% intracerebral hematoma (ICH; median 22 cm3), and 26% intraventricular blood clot (IVH). The outcome was favorable (mRS 0-1) in 45% (54 patients: ICH 44%; IVH clot 31%; shunt 46%), moderate (mRS 2-3) in 30% (36 patients: ICH 64%; IVH clot 19%; shunt 42%), and unfavorable (mRS 4-5) in 25% (30 patients: ICH 80%; IVH clot 23%; shunt 50%). A total of 46% carried a ventriculoperitoneal shunt. ICH volume was a significant predictor of mRS at 3 years. CONCLUSIONS: Of poor-grade aSAH patients, 45% were alive at 3 years, even 27% of those extending to pain (H&H 5). Of the survivors, 75% were at least in moderate condition, while only 2.6% ended in hospice care. Consequently, we propose non-selected admission to neurointensive care (1) for a possibility of moderate outcome, and (2), in case of brain death, possibly improved organ donation rates.

Antipsychotic Use Among 1144 Patients After Aneurysmal Subarachnoid Hemorrhage.

Background and Purpose- At acute phase and neurointensive care, patients with aneurysmal subarachnoid hemorrhage (aSAH) may become agitated or delirious. We found no previous studies on psychotic disorders or antipsychotic drug (APD) use by long-term aSAH survivors. We defined the APD use and its risk factors among 12-month survivors of aSAH in an Eastern Finnish population-based cohort with long-term follow-up. Methods- We analyzed APD use in 1144 consecutive patients with aSAH alive at 12 months of the Kuopio intracranial aneurysm patient and family database and their age, sex, and birth municipality matched controls (3:1; n=3432) from 1995 to 2013 and median follow-up of 9 years. Using the Finish nationwide health registries, we obtained drug purchase and hospital discharge data. Results- In total, 140 (12%) of the 1144 patients started APD use first time after aSAH (index date), in contrast to 145 (4%) of the 3432 matched population controls. The cumulative rate of starting APD was 6% at 1 year and 9% at 5 years, in contrast to 1% and 2% in the controls, respectively. The rates at 1 and 5 years were only 1% and 2% in the 489 patients with a good condition (modified Rankin Scale score, 0 or 1 at 12 months; no shunt, intracerebral hemorrhage, or intraventricular hemorrhage). Instead, the highest rate of APD use, 23% at 5 years was among the 192 patients shunted for hydrocephalus after aSAH. Eighty-eight (63%) of the 140 aSAH patients with APD use had also concomitant antidepressant or antiepileptic drug use. Conclusions- The 12-month survivors of aSAH were significantly more likely to be started on APD after aSAH than their matched population controls. These patients often used antidepressant and antiepileptic drugs concomitantly. The use of APDs strongly correlated with signs of brain injury after aSAH, with low use if no signs of significant brain injury were present.

Analgesic Use after Aneurysmal Subarachnoid Hemorrhage: A Population-Based Case-Control Study of 1187 Patients.

BACKGROUND: The purpose of this population-based case-control study was to evaluate analgesic use after subarachnoid hemorrhage (SAH) caused by rupture of a saccular intracranial aneurysm (sIA). METHODS: The study consisted of 1187 patients alive 12 months after an sIA-SAH who were admitted to Kuopio University Hospital (KUH) between 1995 and 2014. Three controls, matched with age, sex, and birthplace, were included for each patient. Data on ruptured sIA cases admitted to KUH from a defined catchment population in Eastern Finland were obtained from the KUH intracranial aneurysm database. Analgesics were classified according to the Anatomical Therapeutic Chemical Classification system. Data on analgesic medication were retrieved from the Finnish national registry of prescribed medicines of the Social Insurance Institution of Finland. RESULTS: Among 1187 patients with sIA-SAH who were alive 12 months after admission, 83 (7.0%) commenced analgesics use within 12 months after the sIA-SAH versus 53 (1.5%) of the 3561 population controls. The results revealed significantly greater initiation rate of analgesic use among patients with sIA-SAH within a year after sIA-SAH as compared with that of matched population controls (odds ratio 5.0; 95% confidence interval 3.5-7.0; P < 0.001). Analgesic use commencement within 12 months of an sIA-SAH was independently associated with the presence of an intracerebral hematoma. Among patients, commencing analgesic use increased 11% when we compared a year before and a year after sIA-SAH. CONCLUSIONS: Our results indicate that patients with sIA-SAH had an increased risk for new pain after sIA-SAH as compared with that of matched control population.
