RESUMEN
The aim of this study was to evaluate self-reported periodontitis (PD) prevalence in migraineurs as well as to investigate the association between both diseases. A cross-sectional survey was carried out including patients diagnosed with migraine attending 12 Spanish Headache Units. We determined diagnosis of PD administering a validated self-reported questionnaire. Socio-demographic, clinical and medical information, comorbidities, daily habits, migraine characteristics and medication were collected using a questionnaire. Of the 651 consecutive migraineurs included in the study, 393 suffered from chronic migraine (CM). Self-reported PD was detected in 327 patients with migraine (50.2%). Migraineurs with self-reported PD were significantly older and had a previous history of fibromyalgia, stress, anxiety, depression, and allodynia (all P < 0.001). Additionally, this group of patients consumed more topiramate (P = 0.008) and simple analgesics (P < 0.001) than patients with migraine and without self-reported PD. Also, they were less active physically and belonged to a low education level (both P < 0.001). Prevalence of self-reported PD was significantly higher in chronic migraineurs compared to those diagnosed with episodic migraine (EM) (53.9% vs. 44.6%, P = 0.019). Logistic regression analyses showed that self-reported PD was associated with CM (OR 1.456; 95% CI 1.062-1.997, P = 0.020). However, after adjusting for significant confounders, the association was attenuated (OR 1.100; 95% CI 0.784-1.543, P = 0.581). We concluded that self-reported PD was significantly more frequent in CM compared to EM. Self-reported PD was associated with the presence of CM, although some comorbidities shared by both diseases could have an effect on this association.

Cognitive difficulties are reported as lasting sequelae within post COVID-19 condition. However, the chronicity of these difficulties and related factors of fatigue, mood, and perceived health have yet to be fully determined. To address this, the current longitudinal study aimed to clarify the trends of cognitive test performance and cognitive domain impairment following COVID-19 onset, and whether hospitalization influences outcomes. 57 participants who reported subjective cognitive difficulties after confirmed COVID-19 infection were assessed at baseline (~6 months post COVID-19) and follow-up (~15 months later) visits. Assessments included measures across multiple cognitive domains and self-report questionnaires of fatigue, mood, and overall health. Analyses were conducted in three stages: at the test score level (raw and adjusted scores), at the cognitive domain level, and stratified by hospitalization status during infection. Results at the test-score level indicate that cognitive performance remains relatively stable across assessments at the group level, with no significant improvements in any adjusted test scores at follow-up. Cognitive domain analyses indicate significant reductions in attention and executive functioning impairment, while memory impairment is slower to resolve. On self-report measures, there was a significant improvement in overall health ratings at follow-up. Finally, those hospitalized during infection performed worse on timed cognitive measures across visits and accounted for a larger proportion of cases with short-term and working memory impairment at follow-up. Overall, our findings indicate that cognitive difficulties persist both at test score and cognitive domain levels in many cases of post COVID-19 condition, but evidence suggests some improvement in global measures of attention, executive functioning and overall self-rated health. Furthermore, an effect of hospitalization on cognitive symptoms post COVID-19 may be more discernible over time.

Fatigue in its many forms of physical, mental, and psychosocial exhaustion is a common symptom of post-COVID-19 condition, also known as "Long COVID." Persistent fatigue in COVID-19 patients is frequently accompanied by cognitive dysfunction and neuropsychiatric symptoms; however, less is known about the relationships between these components of post-COVID-19 condition and fatigue itself. Consequently, the present study sought to (1) distinguish the types of fatigue experienced by participants, and (2) investigate whether cognitive deficits across various domains and neuropsychiatric conditions predicted these different types of fatigue. The study included 136 COVID-19 patients referred for neuropsychological evaluation due to cognitive complaints 8 months on average after SARS-CoV-2 infection. Measures included self-reported fatigue (physical, cognitive, and psychosocial), neuropsychiatric questionnaires (assessing symptoms of depression, anxiety, apathy, and executive functioning), a comprehensive neuropsychological assessment, and self-reported quality of life and everyday functioning. Results showed that reports of clinical significant fatigue were pervasive in our sample (82.3% of participants), with physical fatigue rated highest on average relative to the subscale maximum. Elevated levels of apathy, anxiety, and executive dysfunction in neuropsychiatric measures along with executive and attentional difficulties on cognitive tests were found to be consistently important predictors among different types of fatigue. This implicates both cognitive and neuropsychiatric symptoms as predictors of fatigue in post-COVID-19 condition, and stresses the importance of a holistic approach in assessing and considering potential treatment for COVID-19 patients experiencing fatigue.

BACKGROUND: While much of the scientific focus thus far has been on cognitive sequelae in patients with severe COVID-19, subjective cognitive complaints are being reported across the spectrum of disease severity, with recent studies beginning to corroborate patients' perceived deficits. In response to this, the aims of this study were to (1) explore the frequency of impaired performance across cognitive domains in post-COVID patients with subjective complaints and (2) uncover whether impairment existed within a single domain or across multiple. METHODS: Sixty-three patients with subjective cognitive complaints post-COVID were assessed with a comprehensive protocol consisting of various neuropsychological tests and mood measures. Cognitive test performance was transformed into T scores and classified based on recommended guidelines. After performing a principal component analysis to define cognitive domain factors, distributions of test scores within and across domains were analyzed. RESULTS: Results revealed pervasive impact on attention abilities, both as the singularly affected domain (19% of single-domain impairment) as well as coupled with decreased performance in executive functions, learning, and long-term memory. These salient attentional and associated executive deficits were largely unrelated to clinical factors such as hospitalization, disease duration, biomarkers, or affective measures. DISCUSSION: These findings stress the importance of comprehensive evaluation and intervention to address cognitive sequelae in post-COVID patients of varying disease courses, not just those who were hospitalized or experienced severe symptoms. Future studies should investigate to what extent these cognitive abilities are recuperated over time as well as employ neuroimaging techniques to uncover underlying mechanisms of neural damage.

BACKGROUND AND PURPOSE: Symptomatic intracerebral hemorrhage (ICH) is a major complication of thrombolysis in patients with acute ischemic stroke. We analyzed whether baseline hemostatic markers could predict symptomatic ICH (SICH). METHODS: In a multicenter study of patients treated with intravenous tissue plasminogen activator (t-PA) within 3 hours of stroke onset, we analyzed the following variables: demographic data, vascular risk factors, blood glucose at admission, time from the onset of symptoms to t-PA infusion, blood pressure, neurological deficit measured by the National Institutes of Health Stroke Scale (NIHSS) score, early signs of ischemia on the baseline computed tomography (CT) scan, and protocol deviations. In blood samples, the following markers of coagulation/fibrinolysis were measured before treatment: fibrinogen, prothrombin fragments 1+2, Factor XIII, Factor VII, alpha2 antiplasmin, plasminogen activator inhibitor-1 (PAI-1), and thrombin-activatable fibrinolysis inhibitor. ICH was classified according to the European Cooperative Acute Stroke Study (ECASS) II criteria. SICH was defined as a parenchymal hematoma-1 (PH1) or PH2 type, associated with an increase in > or =4 points on the NIHSS score appearing within 36 hours after infusion. RESULTS: We studied 114 patients. Mean age was 68.4+/-12.7 years, and 61% were men. The median baseline NIHSS score was 14. Mean time to treatment was 153+/-33 minutes. Eight patients had SICH (7%), and 18 patients (15.7%) had asymptomatic ICH. None of the baseline markers of coagulation/fibrinolysis were associated with SICH. In the multivariate analysis, only NIHSS on admission was an independent risk factor for SICH. CONCLUSIONS: None of the hemostatic markers analyzed in our study predicted symptomatic cerebral hemorrhage in patients with ischemic stroke treated with t-PA.

BACKGROUND AND PURPOSE: It would be useful to have a noninvasive test for correlation with CT findings in patients with intracerebral hemorrhage (ICH). We determined which transcranial Doppler (TCD) variables are related to which CT data in patients with ICH. METHODS: We prospectively included 51 patients (age +/- SD, 66.2 +/- 12.4 years; 30 men, 21 women) with first-ever supratentorial, nontraumatic ICH. CT and TCD examination were performed in the acute stage (less than 12 hours from symptom onset). TCD recordings were obtained from the middle cerebral arteries, and the following variables were analyzed: systolic (Vs), diastolic (Vd), mean (Vm) velocities, and pulsatiliy index from the affected (a) and unaffected (u) hemispheres. RESULTS: PIs obtained for both hemispheres were positively correlated with hematoma volume (aPI, r=0.43, P=.001; uPI, r=0.44, P=.001), volume of hypoattenuation (aPI r=0.64, P <.0001; uPI, r=0.39, P=.005), total volume (aPI, r=0.59, P <.0001; uPI, r=0.48, P <.0001), and midline shift (aPI, r=0.28, P=.04; uPI, r=0.29, P=.03). Both PIs were increased in patients with intraventricular hemorrhage (aPI, P=.01; uPI P=.004). No TCD parameter was correlated with ventricular size. CONCLUSION: Most TCD parameters were correlated with CT data in the acute stage of ICH. An increase in PI probably reflects intracranial hypertension and mass effect. Further studies are needed to determine the clinical application of our findings.

INTRODUCCIÓN: La infección por SARS-CoV-2 ha tenido un enorme impacto en los sistemas sanitarios. España, donde la cefalea constituye el motivo principal de consulta ambulatoria en Neurología, es uno de los países con más casos notificados. OBJETIVO: Conocer el impacto de la pandemia COVID-19 en las Unidades de Cefaleas en España y evaluar cómo imaginan el futuro de estas estructuras los neurólogos responsables. MÉTODOS: estudio transversal mediante encuesta online distribuida a los responsables de las Unidades, realizada durante la sexta semana del Estado de Alarma. RESULTADOS: La tasa de respuesta fue del 74%, con participación de centros de diferentes características y de todas las Comunidades Autónomas. El 95,8% describió limitaciones en la actividad presencial, un 60,4% mantuvo la consulta presencial preferente y el 45,8% los procedimientos urgentes. En el 91,7% de los centros la actividad presencial cancelada se sustituyó por consulta telefónica. El 95,8% de los encuestados afirmó que empleará material de protección personal en el futuro y el 86% pretende incorporar en mayor medida la telemedicina. La mayoría prevé un incremento en las listas de espera (93,8% en primeras visitas, 89,6% en revisiones y 89,4% en procedimientos) y una peor situación clínica de los pacientes, pero sólo un 15% cree que su estructura asistencial se verá debilitada. CONCLUSIONES: Como consecuencia de la pandemia, la actividad asistencial e investigadora en cefaleas se ha reducido de manera notable. Esto pone de manifiesto la necesidad de un incremento de la oferta de telemedicina en nuestros centros en un futuro cercano
INTRODUCTION:The COVID-19 pandemic has had a great impact on healthcare systems. Spain, where headache is the main reason for outpatient neurology consultation, is one of the countries with the most reported cases of the disease.Objectives.This study aimed to analyse the impact of the COVID-19 pandemic on headache units in Spain and to evaluate how neurologists see the future of these units. METHODS: We conducted a cross-sectional online survey of headache units during the sixth week of the state of alarm declared in Spain in response to the pandemic. RESULTS:The response rate was 74%, with the participation of centres with different characteristics and from all Autonomous Communities of Spain. Limitations in face-to-face activity were reported by 95.8% of centres, with preferential face-to-face consultation being maintained in 60.4%, and urgent procedures in 45.8%. In 91.7% of centres, the cancelled face-to-face activity was replaced by telephone consultation 95.8% of respondents stated that they woulduse personal protection equipment in the future, and 86% intendedto increase the use of telemedicine. The majority foresaw an increase in waiting lists (93.8% for initial consultations, 89.6% for follow-up, and 89.4% for procedures) and a worse clinical situation for patients, but only 15% believed that their healthcare structures would be negatively affected in the future.Conclusions.As a consequence of the pandemic, headache care and research activity has reduced considerably. This demonstrates the need for an increase in the availability of telemedicine in our centres in the near future

BACKGROUND AND PURPOSE: Ischemic stroke (IS) is a complex disease that involves genetic and environmental factors. In a family-based study (the Genetic Analysis of Idiopathic Thrombophilia [GAIT] Project) that included a genome-wide scan, we demonstrated that a common polymorphism (46 C-->T) in the exon 1 of the F12 gene jointly influences variability of plasma Factor XII levels and susceptibility to thrombotic disease. We have investigated the risk of IS related to this polymorphism in a case-control study. METHODS: We studied 436 individuals: 205 diagnosed with IS and 231 age-gender-ethnic control subjects. We measured Factor VIIIc, fibrinogen, and Factor XIIc levels, and we genotyped the 46 C-->T polymorphism in the F12 gene. RESULTS: There were 91 women and 114 men in the IS group and 109 women and 122 men in the control group. We confirmed our previous observation that individuals with different genotypes for the 46 C-->T polymorphism showed significant differences in Factor XIIc levels. Most importantly, the mutated T allele in the homozygous state (genotype T/T) was associated with an increased risk of IS with an adjusted odds ratio of 4.1 (95% CI, 1.1 to 15.9). CONCLUSIONS: This study suggests that the 46 C-->T polymorphism is a genetic risk factor for IS in the Spanish population. In addition, our results confirm that the use of genetic linkage studies along with a case-control association study is an extremely valuable approach for identifying DNA variants that affect complex diseases.

The efficacy of thrombolysis in clinical stroke subtypes is unclear. We compared the benefit of intravenous rt-PA in 11 patients with lacunar syndrome with that in 33 patients with a non-lacunar syndrome. Patients were matched by NIHSS score and time to treatment. Although no statistically significant differences were detected in outcome, the benefit was greater in the non- lacunar syndrome group.
