Longitudinal health-related quality of life (QoL) data in Guillain-Barré (GBS) patients are still scarce. We, therefore, investigated health- related QoL in GBS patients from Serbia and surrounding countries during a six-month follow-up period, and analyzed its association with patients' disability. Our study comprised 74 adult patients diagnosed with GBS from May 2017 until May 2018 in seven tertiary healthcare centers. Health-related QoL was investigated using the SF-36 questionnaire, and compared with functional disability assessed by the GBS disability scale (GDS). Tests were performed at day 14, day 28, month 3 and month 6 from disease onset. GDS and SF-36 scores improved over time (p < 0.01). GDS scores were different at all four time points, while SF-36 did not differ between day 14 and day 28. Pooled SF-36 scores (especially physical ones) correlated with pooled GDS scores, except for Bodily Pain and Role Emotional scores. We found that GDS score at day 14 was an independent predictor of GDS score at month 6 (β = +0.52, p < 0.01), while SF-36 score at day 14 was an independent predictor of SF-36 score at month 6 (β = +0.51, p < 0.01). Neurologists should look not only on disability but also on QoL in GBS patients, since these two measures provide us with important complementary items of information. © 2020 Elsevier Ltd

Background Data based on randomized clinical trials regarding the efficacy and safety of intravenous thrombolysis (IVT) versus placebo or any other antithrombotic agent in the treatment of stroke associated with atrial fibrillation (AF) are unavailable.; Methods Prospectively collected data on AF-associated stroke patients treated in a 3-year period were analyzed to assess the effect of IVT treatment. Outcome measures were modified Rankin Scale (mRS) score for functional outcome, death, and symptomatic intracerebral hemorrhage (sICH).; Results Of 787 patients diagnosed with an acute ischemic stroke in the observed period, 131 (16.6%) had AF. Multivariate logistic regression analysis after adjustment for confounders demonstrated that independent predictors of excellent outcome (mRS 0-1) in patients with AF-associated stroke were lower baseline National Institutes of Health Stroke Scale [NIHSS] score (adjusted odds ratio [adjOR],.87; 95% confidence interval [CI], 0.81-.94; P =.000) and the use of IVT (adjOR, 5.31; 95% CI, 1.90-14.82; P =.001), whereas independent predictors of death were higher baseline NIHSS score (adjOR, 1.07; 95% CI, 1.02-1.12; P =.003), previous stroke (adjOR, 4.11; 95% CI, 1.49-11.35; P =.006), absence of IVT use (adjOR,.19; 95% CI,.05-.77; P =.021), sICH (adjOR, 18.52; 95% CI, 1.59-215.37; P =.020), and higher serum glucose levels (adjOR, 1.26; 95% CI, 1.06-1.50; P =.008). Thrombolyzed patients with AF were less severe at baseline and were less likely to have NIHSS >18. They were more likely to have excellent and good functional outcome (mRS 0-2) whereas less likely to have death as outcome at 3 months. Thrombolyzed AF patients had constantly lower probability of death regardless of the baseline NIHSS score values.; Conclusions These results should encourage the use of IVT in AF-associated strokes. © 2014 National Stroke Association.

Objective: Headache is a common symptom of cerebrovascular events, particularly of intracerebral hemorrhage (ICH), where it can occur at the onset or at some time in the course of the disease. The aim of this paper is to evaluate the important characteristics for the clinical course and outcome in a group of patients with headache at the onset of ICH. Patients and Methods: A prospective analysis of 144 patients with non-traumatic ICH, conservatively treated in a 2 1/4 year period at the Clinical Center of Serbia, Department of Emergency Neurology, Belgrade, was performed. The patients were divided in two groups based on the first symptoms of ICH. The first group consisted of patients in whom the ICH began with headache, nausea, and vomiting, while the second group included patients who had loss of consciousness, seizures, or focal neurological deficit. The groups were compared by age and gender, the existence of chronic hypertension, and the results of the first physical and neurological examination performed at admission. The results of these first examinations were scored by GCS and NESS. The location and size of the hematoma, the presence of edema, hydrocephalus, displacement of the medial brain structures, and intraventricular or subarachnoidal blood propagation was established by CT scan. The patients were followed for 30 days. Mortality and functional outcome of the surviving patients was then determined. These characteristics ware analyzed by Student-T and χ2 test. The significance was placed at p ≤ 0.05. Results: Of 144 patients with ICH, 43 (29.9 per- cent) had headache at the onset, 29 (20.1 percent) had loss of conscious- ness, 10 (6.9 percent) had epileptic seizures, and 62 (43.1 percent) had a focal neurological deficit. When clinical characteristics were compared, only the values of NESS were significantly lower in the headache group (13 ± 6.7), in comparison with the other patients (17 ± 6.4). When CT characteristics were compared, only the localization of the hematoma was significantly different Forty- seven percent of patients with lobar hematoma had headache, in comparison to 24 percent of the patients with basal-ganglion hematoma, in whom ICH more frequently began in another manner (76 percent). Conclusion: We conclude that almost one-third of patients with ICH have headache as a first symptom, which in some cases prolongs the time of recognition and appropriate treatment. The testing of clinical and CT characteristics showed that them are no features that differ in this group of patients in comparison with patients in whom ICH begins in another manner. A somewhat higher incidence of headache in the lobar hematoma group indicates arteriography is needed to fulfill the diagnosis. Although the patients with headache have a less dramatic onset of ICH than patients with loss of consciousness or hemiparesis, a similar mortality rate between these two groups of patients indicates that head- ache cannot be used as an element of prognosis in ICH.

Guillain-Barré syndrome (GBS) is an acute auto-immune polyradiculoneuropathy. A huge variety of GBS incidence and mortality rates has been noted across the world. The objective of the present multi-centric study was to assess the incidence and mortality rates of GBS during a 10-year period in Serbia. We collected data of adult GBS patients who were hospitalized from 2009 to 2018 in all five tertiary healthcare centers in Serbia. The incidence rates per 100 000 inhabitants with 95% confidence intervals (CI) were calculated and further corrected for the estimated number of patients hospitalized in secondary centers. Mortality rates were also assessed. GBS was considered severe if patients were not able to walk at least 10 m without assistance. Six hundred and forty GBS patients were registered in tertiary centers in a 10-year period. The proportion of severe cases was 75% at nadir, and 52% on discharge. GBS incidence rate in Serbia was 1.1 per 100 000 inhabitants, and estimated incidence if patients from secondary centers included 1.2 per 100 000. Peak incidence was observed during the sixth decade of life. During the acute phase, 5.6% of GBS patients died, while overall 9.7% of them died during 6-month period from disease onset. This study contributes to our knowledge about GBS epidemiology. Results will allow us to improve the diagnosis and treatment of GBS patients in Serbia. © 2020 Peripheral Nerve Society.

Recurrent Guillain-Barré syndrome (RGBS) episodes appear in up to 6% of Guillain-Barré syndrome (GBS) patients. The purpose of this study was to identify patients with previous episodes of GBS and to assess their clinical features in a large cohort of adult GBS patients. GBS patients hospitalized at tertiary centers in three Balkan countries were included in the study (n = 404). We identified 13 (3.2%) patients with recurrent GBS (RGBS). The male to female ratio was 3: 1. All RGBS patients had two episodes of the disease. The most common GBS subtype in both episodes of the disease was acute inflammatory demyelinating polyradiculoneuropathy (AIDP) (77%, first episode; 85%, second episode). Around 23% of patients presented with a different variant during the second GBS attack. Disability seems to be equally severe at both episodes (P > 0.05). Recurrent GBS was registered in 3% of our GBS patients. The majority of them were younger males. Different GBS subtypes were found to recur. © 2019 Neurology India, Neurological Society of India.

Objective: Sex differences regarding the safety and efficacy of carotid revascularization in carotid artery stenosis have been addressed in several studies with conflicting results. Moreover, women are underrepresented in clinical trials, leading to limited conclusions regarding the safety and efficacy of acute stroke treatments. Methods: A systematic review and meta-analysis was performed by literature search including four databases from January 1985 to December 2021. Sex differences in the efficacy and safety of revascularization procedures, including carotid endarterectomy (CEA) and carotid artery stenting (CAS), for symptomatic and asymptomatic carotid artery stenoses were analyzed. Results: Regarding CEA in symptomatic carotid artery stenosis, the stroke risk in men (3.6%) and women (3.9%) based on 99,495 patients (30 studies) did not differ (P =.16). There was also no difference in the stroke risk by different time frames up to 10 years. Compared with men, women treated with CEA had a significantly higher stroke or death rate at 4 months (2 studies, 2565 patients; 7.2% vs 5.0%; odds ratio [OR], 1.49; 95% confidence interval [CI], 1.04-2.12; I2 = 0%; P =.03), and a significantly higher rate of restenosis (1 study, 615; 17.2% vs 6.7%; OR, 2.81; 95% CI, 1.66-4.75; P =.0001). For CAS in symptomatic artery stenosis, data showed a non-significant tendency toward higher peri-procedural stroke in women, whereas for asymptomatic carotid artery stenosis, data based on 332,344 patients showed that women (compared with men) after CEA had similar rates of stroke, stroke or death, and the composite outcome stroke/death/myocardial infarction. The rate of restenosis at 1 year was significantly higher in women compared with men (1 study, 372 patients; 10.8% vs 3.2%; OR, 3.71; 95% CI, 1.49-9.2; P =.005). Furthermore, CAS in asymptomatic patients was associated with low risk of a postprocedural stroke in both sexes, but a significantly higher risk of in-hospital myocardial infarction in women than men (8445 patients, 1.2% vs 0.6%; OR, 2.01; 95% CI, 1.23-3.28; I2 = 0%; P =.005). Conclusions: A few sex-differences in short-term outcomes after carotid revascularization for symptomatic and asymptomatic carotid artery stenosis were found, although there were no significant differences in the overall stroke. This indicates a need for larger multicenter prospective studies to evaluate these sex-specific differences. More women, including those aged over 80 years, need to be enrolled in randomized controlled trials, to better understand if sex differences exist and to tailor carotid revascularization accordingly. © 2023 The Authors

A majority of patients with Guillain-Barré syndrome (GBS) have tendency of a good recovery. Our aim was to evaluate the outcome of the disease 1 and 3 years after GBS symptom onset. Methods: During 2014, GBS was diagnosed in 82 patients in seven tertiary healthcare centers. Neurological follow-up was conducted in 57 (70%) patients after 1 year, and in 54 (66%) after 3 years. Functional disability was estimated according to the GBS disability scale (GDS), with a score of 0-3 indicating mild disability and a score of 4-6 indicating severe disability during acute phase, whereas a score >1 indicated poor recovery on follow-ups. Visual analog scale was used to assess sensory symptoms and musculoskelatal pain, and Krupp's Fatigue Severity Scale was used to asses fatigue. Results: Poor functional outcome was found in 39% of GBS patients at year 1 and 30% at year 3. Paresthesias/dysesthesias were detected in 60% of patients after 1 year and 43% after 3 years. Musculoskeletal pain was present in 40% of patients at year 1 and 33% at year 3. Significant fatigue after 1 year was found in 21% of subjects and after 3 years in 7%. Parameters associated with poor functional outcome after 1 year were age >55 years (p=0.05), severe disability at admission (p<0.05), and on discharge (p<0.01). Poor functional outcome after 3 years was associated with male gender (p<0.05) and severe disability on discharge (p=0.06). Conclusion: One and even three years after GBS onset, a substantial number of patients had neurological sequelae, including functional disability, sensory symptoms, pain, and fatigue. © 2018 The Canadian Journal of Neurological Sciences Inc.
