UNASSIGNED: Decompressive craniectomy (DC) is a neurosurgical technique that is gaining renewed interest due to the worldwide resurgence of head injuries. We aimed to analyze the quality of management and prognosis of patients who underwent this surgery in the context of limited resources.
UNASSIGNED: This was a prospective, longitudinal, descriptive, and analytical study following STROBE, lasting 36 months at the National Hospital of Niamey in patients who had undergone DC. P ≤ 0.05 was considered significant.
UNASSIGNED: During our study, we collected 74 cases of DC. The mean age was 32.04 years (10-75 years), with male predominance (91.89%). DC was mainly performed following head trauma (95.95%), the main cause of which was road traffic accidents (76%; 54/71). On admission, most patients presented with altered consciousness (95.95%) and pupillary abnormalities (62.16%). The average time between brain damage and brain scan was 31.28 h, with parenchymal contusion being the most frequent lesion (90.54%). The majority of patients (94.59%) underwent decompressive hemicraniectomy. Postoperative complications accounted for 71.62% of all cases, with 33.78% resulting in death. Among survivors, 55.10% had neurological sequelae at the last consultation (27/49). The main factors associated with the risk of death and morbidity were a Glasgow coma score ≤8, pupillary abnormality on admission, the presence of signs of brain engagement, and a long admission delay.
UNASSIGNED: Our study shows that the impact of limited resources on our care is moderate. Future research will concentrate on long-term monitoring, particularly focusing on the psychosocial reintegration of patients post-DC.

UNASSIGNED: Heart disease remains the leading cause of death in developed countries, and cigarette smoking contributes to a significant proportion of cardiovascular-related deaths. Abstaining from tobacco use is associated with a significant reduction in the risk of recurrent myocardial infarctions.
UNASSIGNED: In this cross-sectional study, 384 participants post-acute myocardial infarction (MI) were recruited through random sampling to explore the associations between smoking status and intention to quit smoking. Data collection took place over a 6-month period at a tertiary care hospital, Islamabad, Pakistan.
UNASSIGNED: The majority of participants were male (59.9%) and fell into the age category of 46-50 years (37.5%). Heavy daily smokers comprised the largest smoking group (41.6%), and non-ST-elevated MI was the most common subtype (40.1%). Intention to quit smoking varied among participants, with the pre-contemplation stage having the highest representation (19.3%), followed by contemplation (25.8%). Notably, a significant proportion of participants expressed no intention to quit smoking (35.4%).
UNASSIGNED: Multinomial logistic regression analysis identified current smoking as a significant predictor of intention to quit in the preparation and contemplation stages. Overall, this study underscores the importance of considering smoking behaviour when evaluating the intention to quit smoking post-MI and highlights the need for tailored interventions and support strategies to address smoking cessation in this population. These findings offer valuable insights for the development of effective strategies aimed at reducing persistent smoking following MI and improving patient outcomes.

OBJECTIVE: To investigate the efficacy and safety of tirofiban and low molecular weight heparin (LMWH) in the treatment of patients undergoing acute progressive pontine infarction.
METHODS: Patients with acute progressive pontine infarction who were hospitalized in the Neurology Department from June 2021 to June 2023 were included in the study and randomly divided into two groups, namely the experimental group (tirofiban group) and the control group (LMWH group). All patients in both groups were required to receive conventional comprehensive treatment and dual antiplatelet therapy with aspirin + clopidogrel at the beginning of admission. The National Institutes of Health Stroke Scale (NIHSS) score and Barthel Index (BI) were used to evaluate the neurological deficits on the first day of admission, the next day with stroke progression, and at discharge after treatment with tirofiban and LMWH, respectively in the two groups. The modified Rankin Scale was employed to assess prognosis on the 90th day after treatment. Clinical adverse events were followed up for 90 days, comparing the clinical efficacy and safety of the two treatment methods.
RESULTS: There was no statistical significance in NIHSS score and Barthel Index between the tirofiban group and the LMWH group on the first day of admission and the next day with stroke progression (p > 0.05). After stroke progression, tirofiban and LMWH were separately used for treatment in the two groups. We found that the NIHSS score of the tirofiban group was lower than that of the LMWH group, and the Barthel Index score was higher than that of the LMWH group at discharge (p < 0.05). After three months of follow-up, the mRS score of the tirofiban group was dramatically higher than that of the LMWH group (p < 0.05). No significant harmful or adverse reactions, such as bleeding events, were found in the two groups (p > 0.05).
CONCLUSIONS: Tirofiban may be more effective and safer than LMWH in controlling the progression of acute pontine infarction, but further and large-sample studies are still needed to confirm this finding.

BACKGROUND: Strictly superficial cerebellar microbleeds and cerebellar superficial siderosis have been considered markers of advanced cerebral amyloid angiopathy (CAA), but there are few studies on cerebellar ischemic lesions in CAA. We investigated the presence of superficial small cerebellar infarct (SCI) ≤15 mm and its relation to magnetic resonance imaging (MRI) markers in patients with probable CAA.
METHODS: Eighty patients with probable CAA were retrospectively evaluated. The presence of superficial SCIs was examined, along with cerebellar microbleeds and cerebellar superficial siderosis, using 3-T MRI. Lobar cerebral microbleeds, cortical superficial siderosis (cSS), enlargement of the perivascular space in the centrum semiovale, and white matter hyperintensity were assessed and the total CAA-small vessel disease (SVD) score was calculated.
RESULTS: Nine of the 80 patients (11.3%) had a total of 16 superficial SCIs. By tentatively defining SCI <4 mm as cerebellar microinfarcts, 8 out of 16 (50%) superficial SCIs corresponded to cerebellar microinfarcts. The total CAA-SVD score was significantly higher in patients with superficial SCIs (p = 0.01). The prevalence of cSS (p = 0.018), cortical cerebral microinfarct (p = 0.034), and superficial cerebellar microbleeds (p = 0.006) was significantly higher in patients with superficial SCIs. The number of superficial cerebellar microbleeds was also significantly higher in patients with superficial SCIs (p = 0.001).
CONCLUSIONS: Our results suggest that in patients with CAA, superficial SCIs (including microinfarcts) on MRI may indicate more severe, advanced-stage CAA. These preliminary findings should be verified by larger prospective studies in the future.

OBJECTIVE: Persistent headache attributed to ischemic stroke (PHPIS) is increasingly acknowledged and was added to the 2018 ICHD-3. Intravenous thrombolysis (IVT) is a common treatment for acute ischemic stroke. It remains unknown whether this treatment influences the occurrence of a persistent poststroke headache. We aimed to describe the incidence and clinical characteristics of persistent headaches occurring after acute ischemic stroke in patients with or without IVT and explore the risk factors.
METHODS: A prospective observational study was performed between the 234 individuals who received IVT and 226 individuals without IVT in 5 stroke units from Wuhan, China. Subjects were followed for 6 months after stroke via a structured questionnaire.
RESULTS: Age, gender, vascular risk factors, and infarct location/ circulation distribution did not differ between the groups, although IVT group had higher initial NIHSS scores. At the end of the follow-up, 12.0% (55/460) of subjects reported persistent headaches after ischemic stroke. The prevalence of persistent headache was significantly higher in the IVT group than non-IVT group (15.4% vs. 8.4%, p = .021). Patients with younger age (p = .033; OR 0.97; 95% CI 0.939-0.997), female sex (p = .007; OR 2.40; 95% CI 1.269-4.520), posterior circulation infarct (p = .024; OR 2.19; 95% CI 1.110-4.311), and IVT (p = .005; OR 2.51; 95% CI 1.313-4.782) were more likely to develop persistent headache after ischemic stroke.
CONCLUSIONS: The potential influence of IVT should be considered when assessing persistent poststroke headache. Future studies will investigate the underlying mechanisms.

UNASSIGNED: Inflammatory type focal cerebral arteriopathy (FCA-i) in the anterior circulation (AC) is well characterized, and the focal cerebral arteriopathy severity score (FCASS) reflects the severity of the disease. We identified cases of FCA-i in the posterior circulation (PC) and adapted the FCASS to describe these cases.
UNASSIGNED: In this comparative cohort study, patients from the Swiss NeuroPaediatric Stroke Registry with ischemic stroke due to FCA-i between January 2000 and December 2018 were analyzed. A comparison between PC and AC cases regarding pediatric National Institutes of Health Stroke Scale score and pediatric stroke outcome measure and FCASS was performed. We estimated infarct size by the modified pediatric Alberta Stroke Program Early Computed Tomography Score in children with AC stroke and the adapted Bernese posterior diffusion-weighted imaging score in the PC.
UNASSIGNED: Thirty-five children with a median age of 6.3 (interquartile range, 2.7-8.2 [95% CI, 0.9-15.6]; 20 male; 57.1%) years with FCA-i were identified. The total incidence rate was 0.15/100 000/year (95% CI, 0.11-0.21). Six had PC-FCA-i. Time to final FCASS was longer in the PC compared with AC; the evolution of FCASS did not differ. Initial pediatric National Institutes of Health Stroke Scale score was higher in children with FCA-i in the PC with a median of 10.0 (interquartile range, 5.75-21.0) compared with 4.5 (interquartile range, 2.0-8.0) in those with AC-FCA-i. Different from the anterior cases, PC infarct volume did not correlate with higher discharge, maximum, or final FCASS scores (Pearson correlation coefficient [r], 0.25, 0.35, and 0.54).
UNASSIGNED: FCA-i also affects the PC. These cases should be included in future investigations into FCA-i. Although it did not correlate with clinical outcomes in our cohort, the modified FCASS may well serve as a marker for the evolution of the arteriopathy in posterior FCA-i.

BACKGROUND: Anemia is a common complication of aneurysmal subarachnoid hemorrhage and is associated with unfavorable outcomes. Whether the physiological benefits of transfusion for anemia surpass the risk of blood transfusion remains to be determined.
OBJECTIVE: The primary outcome was to evaluate the impact of peri-operative blood transfusion on the long-term neurological outcome, assessed by Glasgow Outcome Scale Extended at 3 months. The secondary outcomes included the impact of transfusion on the short-term neurological outcome, assessed by Modified Rankin Score at discharge/7 days, and on the incidence of vasospasm, infarction, re-exploration, tracheostomy, and length of hospital stay.
METHODS: This prospective observational study was conducted on 185 patients with aneurysmal subarachnoid hemorrhage undergoing clipping of the aneurysmal neck. In our study, blood transfusion was administered to keep the target Hb around 10 g/dL.
RESULTS: Unfavorable long-term outcome was found in 27/97 (28%) of patients who received a blood transfusion as compared to 13/74 (18%) of patients who did not receive a transfusion (P = 0.116). Patients receiving transfusion had more chances of an unfavorable outcome at discharge/7 days as compared to those not transfused [44/103 (43%) versus 22/80 (27%)], P = 0.025. There were increased chances of vasospasm, infarction, re-exploration, tracheostomy, and increased length of hospital stay in patients receiving transfusion (P < 0.05).
CONCLUSIONS: The use of blood transfusion in patients with aneurysmal subarachnoid hemorrhage was associated with increased neurological complications and hence an unfavorable short-term outcome. However, when used judiciously as per the clinical requirements, blood transfusion did not have a significant effect on long-term neurological outcome.

The study investigated surgical interventions to improve dysphagia in patients with lateral medullary syndrome (LMS), along with optimal scheduling of surgery and prognostic factors. In this retrospective, single-center cohort study, dysphagia patients with LMS who underwent surgery between January 2010 and December 2021 were enrolled. The National Outcomes Measurement System (NOMS) was used to classify swallowing function (level 1: only tube feeding, level 5: without tube feeding). Patients were divided into four groups. Groups 1 and 2, LMS onset within 1 year, and groups 3 and 4, onset after 1 year. Groups 1 and 3 had infarctions confined to the oblongata. Groups 2 and 4 had infarctions extending to the cerebellum. The primary outcome was the time to achieve NOMS ≥ 5. The final NOMS level and pathological findings were considered. Nineteen cases were included. Group 4 comprised one case and was excluded. The mean overall preoperative NOMS was 1.11. The mean time to NOMS ≥ 5 was 9.6 months (95% confidence interval: 5.04-14.2), and that to NOMS ≥ 5 was 1.67 (1.07-2.26), 11.4 (4.71-18.1), and 7.6 (5.15-10.1) months for groups 1, 2, and 3, respectively. Group 1 achieved NOMS ≥ 5 earlier than groups 2 and 3 (P = 0.01 and 0.03, respectively). The overall final NOMS value was 4.68. Fourteen patients had atrophy or fibrosis of the cricopharyngeal muscle. In conclusion, surgery was effective for effective for treating dysphagia in LMS patients. However, improvement is prolonged if > 1 year has passed since onset or the infarction extended to the cerebellum.

BACKGROUND: Two of the main causes for dementia are Alzheimer\'s disease (AD) and vascular pathology, with most patients showing mixed pathology. Plasma biomarkers for Alzheimer\'s disease-related pathology have recently emerged, including Aβ (amyloid-beta), p-tau (phosphorylated tau), NfL (neurofilament light), and GFAP (glial fibrillary acidic protein). There is a current gap in the literature regarding whether there is an association between these plasma biomarkers with vascular pathology and neurodegeneration.
RESULTS: Cross-sectional data from 594 individuals (mean [SD] age: 64 [8] years; 17% female) were included from the SMART-MR (Second Manifestations of Arterial Disease-Magnetic Resonance) study, a prospective cohort study of individuals with a history of arterial disease. Plasma markers were assessed using single molecular array assays (Quanterix). Magnetic resonance imaging markers included white matter hyperintensity volume, presence of infarcts (yes/no), total brain volume, and hippocampal volume assessed on 1.5T magnetic resonance imaging. Linear regressions were performed for each standardized plasma marker with white matter hyperintensity volume, total brain volume, and hippocampal volume as separate outcomes, correcting for age, sex, education, and intracranial volume. Logistic regressions were performed for the presence of lacunar and cortical infarcts. Higher p-tau181 was associated with larger white matter hyperintensity volume (b per SD increase=0.16 [95% CI, 0.06-0.26], P=0.015). Higher NfL (b=-5.63, [95% CI, -8.95 to -2.31], P=0.015) was associated with lower total brain volume and the presence of infarcts (odds ratio [OR], 1.42 [95% CI, 1.13-1.78], P=0.039). Higher GFAP levels were associated with cortical infarcts (OR, 1.45 [95% CI, 1.09-1.92], P=0.010).
CONCLUSIONS: Plasma biomarkers that have been associated with tau pathology, axonal injury, and astrocytic activation are related to magnetic resonance imagingmarkers of vascular pathology and neurodegeneration in patients with manifest arterial disease.

Aneurysmal subarachnoid hemorrhage (aSAH) from a ruptured intracranial aneurysm is a severe, life-threatening condition, with high morbidity and mortality. The current treatment often involves surgical clipping or endovascular treatment within the first 24-48 hours. Although there is ample evidence of complications in treating unruptured aneurysms, similar data in patients with acutely ruptured aneurysms are limited. The recently completed EARLYDRAIN trial showed improved neurologic results from lumbar drainage after aneurysm treatment in patients with aSAH. Using this data set, we aim to study the frequency and effects of complications and identify associated risk factors.
A substudy was carried out of the prospective multicenter randomized controlled EARLYDRAIN trial. We analyzed treatment-associated complications (bleeding and/or infarctions) detected on computed tomography on day 1 after aneurysm occlusion. Outcomes were the occurrence of postprocedural complications, secondary infarctions in the acute phase, and the modified Rankin Scale score after 6 months.
The EARLYDRAIN trial recruited 287 patients in 19 centers. Of these patients, 56 (19.5%) experienced a treatment complication. Twenty-five patients (8.7%) experienced postprocedural intracranial hemorrhage and 34 patients (11.8%) experienced a treatment-associated infarction. Patients with a complication showed more secondary infarctions (P = 0.049) and worse neurologic outcomes after 180 days (P = 0.025) compared with patients with no complication. Aneurysm location, rebleeding before the treatment, number of patients recruited per center, and the day of the treatment were independent risk factors for the occurrence of complications.
The present study shows that patients with aSAH frequently experience intervention-associated complications associated with aneurysm occlusion required to prevent recurrent hemorrhage. Consequently, patients with aSAH with treatment-related complications more often experience a worse clinical course and poor outcome.
