Development of an International Standard Set of Outcomes and Measurement Methods for Routine Practice for Infants, Children, and Adolescents with Epilepsy: The International Consortium for Health Outcomes Measurement Consensus Recommendations.

At present, there is no internationally accepted set of core outcomes or measurement methods for epilepsy clinical practice. The International Consortium for Health Outcomes Measurement (ICHOM) convened an international working group of experts in epilepsy, people with epilepsy, and their representatives to develop minimum sets of standardized outcomes and outcome measurement methods for clinical practice. Using modified Delphi consensus methods with consecutive rounds of online voting over 12 months, a core set of outcomes and corresponding measurement tool packages to capture the outcomes were identified for infants, children, and adolescents with epilepsy. Consensus methods identified 20 core outcomes. In addition to the outcomes identified for the ICHOM Epilepsy adult standard set, behavioral, motor, and cognitive/language development outcomes were voted as essential for all infants and children with epilepsy. The proposed set of outcomes and measurement methods will facilitate the implementation of the use of patient-centered outcomes in daily practice.

Development of an International Standard Set of Outcomes and Measurement Methods for Routine Practice for Adults with Epilepsy: The International Consortium for Health Outcomes Measurement Consensus Recommendations.

At present, there is no internationally accepted set of core outcomes or measurement methods for epilepsy clinical practice. Therefore, the International Consortium for Health Outcomes Measurement (ICHOM) convened an international working group of experts in epilepsy, people with epilepsy and their representatives to develop minimum sets of standardized outcomes and outcomes measurement methods for clinical practice that support patient-clinician decision-making and quality improvement. Consensus methods identified 20 core outcomes. Measurement tools were recommended based on their evidence of strong clinical measurement properties, feasibility, and cross-cultural applicability. The essential outcomes included many non-seizure outcomes: anxiety, depression, suicidality, memory and attention, sleep quality, functional status, and the social impact of epilepsy. The proposed set will facilitate the implementation of the use of patient-centered outcomes in daily practice, ensuring holistic care. They also encourage harmonization of outcome measurement, and if widely implemented should reduce the heterogeneity of outcome measurement, accelerate comparative research, and facilitate quality improvement efforts.

Causes and prognosis of adults experiencing a first seizure in adulthood: A pilot cohort study conducted in five countries in Latin America.

There are limited data on first seizure (FS) among adults in low and middle-income countries. We describe findings from a prospective cohort study involving 180 adults presenting with seizures in emergency departments in five Latin American countries. Overall, 102 participants (56.7%) had acute symptomatic seizures (ASyS) while 78 (43.3%) had unprovoked seizures (UPS). Among patients with ASyS, 55 (53.9%) had structural causes, with stroke (n = 24, 23.5%), tumor (n = 10, 9.8%), and trauma (n = 3, 3%) being the most frequent. Nineteen patients (18.6%) had infectious causes, including four (4%) with meningoencephalitis, three (3%) neurocysticercosis, and two (2%) bacterial meningoencephalitis. Twenty patients (19.6%) had metabolic/toxic evidence, including four (4%) with uremic encephalopathy, two (2%) hyponatremia, and three (3%) acute alcohol intoxication. Immune dysfunction was present in seven (7%) patients and neurodegenerative in two (2%). Among participants with UPS, 45 (57.7%) had unknown etiology, 24 (30.7%) had evidence of structural disorders (remote symptomatic), four (5%) were related to infectious etiology (>7 days before the seizure), and five (6.4%) had genetic causes. During the 3- and 6-month follow-up, 29.8% and 14% of patients with UPS, respectively, experienced seizure recurrence, while 23.9% and 24.5% of patients with ASyS had seizure recurrence. Longer follow-up is necessary to assess seizure recurrence for patients with ASyS after the acute cause is resolved and to determine the 10-year risk of recurrence, which is part of the definition of epilepsy. PLAIN LANGUAGE SUMMARY: We monitored 180 adults who presented with their first seizure in emergency departments across five Latin American countries. Among these patients, 57% had acute symptomatic seizures, with structural causes such as stroke (23%), infection (17%), or tumor (10%) being more prevalent. Among the 43% with unprovoked seizures, 58% showed no identifiable acute cause, while 6.4% were due to genetics. Within 3 months after their initial seizure, 26.6% of individuals experienced a second seizure, with 11.9% continuing to have seizures in Months 3-6. Between Months 3 and 6, an additional 20% of patients encountered a second seizure. Research is needed to better understand the cause and prognosis of these patients to improve outcomes.

Cell wall integrity MAPK pathway is essential for lipid homeostasis.

The highly conserved yeast cell wall integrity mitogen-activated protein kinase pathway regulates cellular responses to cell wall and membrane stress. We report that this pathway is activated and essential for viability under growth conditions that alter both the abundance and pattern of synthesis and turnover of membrane phospholipids, particularly phosphatidylinositol and phosphatidylcholine. Mutants defective in this pathway exhibit a choline-sensitive inositol auxotrophy, yet fully derepress INO1 and other Opi1p-regulated genes when grown in the absence of inositol. Under these growth conditions, Mpk1p is transiently activated by phosphorylation and stimulates the transcription of known targets of Mpk1p signaling, including genes regulated by the Rlm1p transcription factor. mpk1Delta cells also exhibit severe defects in lipid metabolism, including an abnormal accumulation of phosphatidylcholine, diacylglycerol, triacylglycerol, and free sterols, as well as aberrant turnover of phosphatidylcholine. Overexpression of the NTE1 phospholipase B gene suppresses the choline-sensitive inositol auxotrophy of mpk1Delta cells, whereas overexpression of other phospholipase genes has no effect on this phenotype. These results indicate that an intact cell wall integrity pathway is required for maintaining proper lipid homeostasis in yeast, especially when cells are grown in the absence of inositol.

The emergence of yeast lipidomics.

The emerging field of lipidomics, driven by technological advances in lipid analysis, provides greatly enhanced opportunities to characterize, on a quantitative or semi-quantitative level, the entire spectrum of lipids, or lipidome, in specific cell types. When combined with advances in other high throughput technologies in genomics and proteomics, lipidomics offers the opportunity to analyze the unique roles of specific lipids in complex cellular processes such as signaling and membrane trafficking. The yeast system offers many advantages for such studies, including the relative simplicity of its lipidome as compared to mammalian cells, the relatively high proportion of structural and regulatory genes of lipid metabolism which have been assigned and the excellent tools for molecular genetic analysis that yeast affords. The current state of application of lipidomic approaches in yeast and the advantages and disadvantages of yeast for such studies are discussed in this report.

Prevalence of migraine in Latin America.

OBJECTIVE: To determine the 1-year point prevalence of migraine among residents > or =15 years old in 12 Latin American urban communities, and record medical consultation preferences of the identified migraineurs. BACKGROUND: Prevalence of migraine with or without aura in Latin American urban communities has not been established by large-scale population studies. METHODS: A validated face-to-face interview questionnaire based on International Headache Society criteria was completed for all headache sufferers within selected households, in a cross-sectional study. The randomly selected populations were representative of urban communities from the six participating Latin American countries. The questionnaire used was identical in each of the six participating countries. RESULTS: Of the 8618 people available for screening, 62% reported headache and 2637 completed interview questionnaires. Age-adjusted 1-year prevalence of migraine with or without aura for each country was (female/male, %): Argentina 6.1/3.8, Brazil 17.4/7.8, Colombia 13.8/4.8, Ecuador 13.5/2.9, Mexico 12.1/3.9, and Venezuela 12.2/4.7. Migraine prevalence was highest in women aged 30 to 50 years. In the year prior to the study, 42% of individuals interviewed and identified with migraine reported consulting a health professional about their headaches, most frequently (14%) a general practitioner. No previous diagnosis of migraine was reported by 65% of individuals with headache. CONCLUSIONS: In agreement with previous epidemiologic reports, migraine is also a common disorder in Latin American urban communities and predominantly affects women aged 30 to 50 years. Consultation preferences are also similar to those of previous reports.

Clinical characteristics and patterns of medication use of migraneurs in Latin America from 12 cities in 6 countries.

OBJECTIVE: The objective of this study was to document the clinical characteristics of migraine and patterns of medication use in residents > or =15 years old in 12 Latin American urban communities. BACKGROUND: Few large-scale population studies have established the symptoms and disability associated with migraine with or without aura in Latin American urban communities or the pattern of medication use in these regions. METHODS: In this study, subjects in 12 urban communities, from 6 Latin American countries, were surveyed with a validated face-to-face interview questionnaire based on International Headache Society criteria for migraine. The questionnaire was completed during face-to-face interviews with headache sufferers within selected households and included questions about migraine symptoms, migraine-related disability, and the use of health-care resources and medications to treat migraines. RESULTS: Of the 8618 people available for screening, 62% suffered from headaches. Of individuals with migraine, 42% reported consulting a health-care professional about their headaches. Of the migraineurs, 94.2% reported moderate to severe pain. Associated symptoms of nausea or vomiting, photophobia, phonophobia, and osmophobia were common during migraine attacks in 30.3, 76.4, 85.1, and 47.7% of subjects, respectively. The majority of subjects suffered between one and eight migraines each month. Although no previous diagnosis of migraine was reported by 65% of headache sufferers, migraineurs lost an average of 8 days in the preceding 3 months in any of the following areas: school, work, household chores, and/or social, family, or leisure activities. The agents used most widely to treat migraine were paracetamol and salicylates, while nonsteroidal anti-inflammatory drugs, dypirone, and ergotamines were also commonly used. Medication use varied widely among countries, but was predominantly nonprescription. CONCLUSIONS: Migraine is a common disorder in Latin American urban communities imposing significant burden on individuals, families, and communities. The magnitude of the impact and the range of activities affected by migraine are similar to those of previous reports in other regions. The preponderance of nonprescription medications and the scarcity of migraine-specific triptans from the study findings are especially striking.

Olfactory dysfunction in hereditary ataxia and basal ganglia disorders.

In the present study the olfactory system of hereditary ataxia patients was tested using the smell identification test. Two previous findings suggested a possible olfactory impairment in these patients. First, an olfactory dysfunction has been found in different neurodegenerative diseases, and second, human functional imaging has shown cerebellar activation during olfaction. As an initial approach to determine if cerebellar ataxia impairs the olfactory process, cerebellar ataxia patients, along with basal ganglia patients, were tested. The results show an olfactory deficit in both basal ganglia and hereditary ataxia patients. Further exploration of the olfactory capacities in hereditary ataxia is necessary to elucidate the specific nature of the deficits.
