Objective: To determine the parameters for providing primary care in cardiovascular health, with an ethnic and gender focus through telemedicine., Study Design: Systematic Literature Review., Methods: A systematic review was conducted using databases including PUBMED, Cochrane Library, CINAHL, EMBASE VHL, and other relevant sources. We included articles published in the last 15 years on parameters of telemedicine care with a differential approach focusing on ethnicity and gender. Screening, full-text reading, and information extraction were performed in duplicate and independently, though methodological quality assessment was not conducted., Results: Twenty-eight studies were included, with 46.43% originating from Australia and 50.00% employing a qualitative approach. Thirty-five point seventy-one percent provided operational recommendations, and 32.14% related to the ethnic approach. Seven operational categories were identified: holistic approach to health, flexible approach to health, accessible health services, continuous improvement in service quality, culturally appropriate and qualified workforce, self-determination and empowerment, and community participation. Additionally, five categories were identified pertaining to the ethnic approach: public policy in favor of ancestral knowledge in primary health care, training of community agents and health personnel from an intercultural perspective, complementarity between traditional and western health practices, and the recognition of telehealth's value in intercultural approaches., Conclusions: There is a need to adjust operational aspects related to the implementation of indigenous public policy, and to increase the number of qualified community human resources to provide holistic, comprehensive, and culturally appropriate care. Regarding gender, there is a necessity to implement public policy based on health determinants that will dismantle barriers to accessing gender-specific services and comprehensively assess cardiovascular risk., (Copyright © 2024 The Royal Society for Public Health.

Background and Objectives: There is a worldwide increase in the incidence of stroke in young adults, with major regional and ethnic differences. Advancing knowledge of ethnic and regional variation in causes and outcomes will be beneficial in implementation of regional health care services. We studied the global distribution of risk factors, causes, and 3-month mortality of young patients with ischemic stroke, by performing a patient data meta-analysis from different cohorts worldwide., Methods: We performed a pooled analysis of individual patient data from cohort studies that included consecutive patients with ischemic stroke aged 18-50 years. We studied differences in prevalence of risk factors and causes of ischemic stroke between different ethnic and racial groups, geographic regions, and countries with different income levels. We investigated differences in 3-month mortality by mixed-effects multivariable logistic regression., Results: We included 17,663 patients from 32 cohorts in 29 countries. Hypertension and diabetes were most prevalent in Black (hypertension, 52.1%; diabetes, 20.7%) and Asian patients (hypertension 46.1%, diabetes, 20.9%). Large vessel atherosclerosis and small vessel disease were more often the cause of stroke in high-income countries (HICs; both p < 0.001), whereas "other determined stroke" and "undetermined stroke" were higher in low and middle-income countries (LMICs; both p < 0.001). Patients in LMICs were younger, had less vascular risk factors, and despite this, more often died within 3 months than those from HICs (odds ratio 2.49; 95% confidence interval 1.42-4.36)., Discussion: Ethnoracial and regional differences in risk factors and causes of stroke at young age provide an understanding of ethnic and racial and regional differences in incidence of ischemic stroke. Our results also highlight the dissimilarities in outcome after stroke in young adults that exist between LMICs and HICs, which should serve as call to action to improve health care facilities in LMICs., (© 2021 American Academy of Neurology.)

Macrophage migration inhibitory factor (MIF) is a cytokine associated with tissue damage in multiple autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis and psoriatic arthritis. The role of MIF in multiple sclerosis (MS) and the contribution of its polymorphisms are unknown in our population. Therefore, we decided to investigate the genetic association of -794 CATT 5-8 (rs5844572) and -173 G>C (rs755622) MIF polymorphisms with MS, clinical variables and MIF serum levels in the population of western Mexico. 230 MS patients diagnosed according to McDonald criteria and 248 control subjects (CS) were recruited for this study, both polymorphisms were genotyped by PCR and PCR-RFLP and MIF serum levels were measured by ELISA kit. Severity and progression of MS were evaluated by EDSS and MSSS scores, respectively. Genotypes carrying the 5 repeats alleles of -794 CATT 5-8 MIF polymorphism present higher MIF serum levels in comparison with no carriers, and the presence of 5,7 heterozygous genotype contribute to the increase of disease severity and damage progression in MS patients. Notably when we stratified by sex, an effect of risk alleles (7 repeats and -173*C) of both MIF polymorphisms on EDSS and MSSS scores on males was found (p < 0.01). This study suggests that polymorphic alleles of MIF polymorphisms could act as sex-specific disease modifiers that increase the severity and progression of MS in male Mexican-Mestizo western population., (Copyright © 2018 Elsevier B.V.

Introduction: Information regarding hospital arrival times after acute ischaemic stroke (AIS) has mainly been gathered from countries with specialised stroke units. Little data from emerging nations is available. We aim to identify factors associated with achieving hospital arrival times of less than 1, 3, and 6 hours, and analyse how arrival times are related to functional outcomes after AIS., Methods: We analysed data from patients with AIS included in the PREMIER study (Primer Registro Mexicano de Isquemia Cerebral) which defined time from symptom onset to hospital arrival. The functional prognosis at 30 days and at 3, 6, and 12 months was evaluated using the modified Rankin Scale., Results: Among 1096 patients with AIS, 61 (6%) arrived in <1 hour, 250 (23%) in <3 hours, and 464 (42%) in <6 hours. The factors associated with very early (<1 hour) arrival were family history of ischemic heart disease and personal history of migraines; in <3 hours: age 40-69 years, family history of hypertension, personal history of dyslipidaemia and ischaemic heart disease, and care in a private hospital; in <6 hours: migraine, previous stroke, ischaemic heart disease, care in a private hospital, and family history of hypertension. Delayed hospital arrival was associated with lacunar stroke and alcoholism. Only 2.4% of patients underwent thrombolysis. Regardless of whether or not thrombolysis was performed, arrival time in <3 hours was associated with lower mortality at 3 and 6 months, and with fewer in-hospital complications., Conclusions: A high percentage of patients had short hospital arrival times; however, less than 3% underwent thrombolysis. Although many factors were associated with early hospital arrival, it is a priority to identify in-hospital barriers to performing thrombolysis., (Copyright © 2013 Sociedad Española de Neurología.

Introduction: Neuromyelitis optica (NMO) or Devic's disease is an autoimmune, inflammatory and demyelinating central nervous system disorder that affects mainly to optic nerve and spinal cord. Recent advances have substantially permitted to expand the knowledge about this entity., Aim: To present a clinical update on the current understanding of the nature, progression, diagnosis and treatment of NMO., Development: Due to its demyelinating nature and its recurrent behavior in most cases, NMO was first considered a form of multiple sclerosis (MS). However, recent findings have led to the conclusion that NMO is a distinct disorder, presenting important immunopathological, clinical, prognostic and therapeutic differences from MS. Fundamental in the under-standing of the disease was the recent discovery of antibodies directed against aquaporin-4 (anti-AQP4, also known as NMO-IgG), which are present in the majority of NMO cases clinically defined, and in a minority of patients with MS. Despite the knowledge on its immunopathogenesis and advances in diagnosis, the treatment of NMO is still challenging., Conclusion: NMO is a demyelinating disease different from MS. Current diagnostic criteria have been enriched with the recent description of the humoral disorder underlying NMO. However, current treatment options for NMO are far from being ideal.

Some neuroprotective agents have shown benefits in animal models, but disappointing results in humans. Citicoline is used in several countries as coadjuvant treatment in acute ischemic stroke (AIS) patients; however, there are no retrospective postmarketing surveillances on the experience of citicoline in Mexico. The aim of this study was to evaluate the correlation between citicoline exposure and functional outcome at discharge and at 30 and 90 days post-stroke, in a retrospective case-control design on systematic descriptive databases from three referral hospitals. Clinical records of 173 consecutively registered patients were analyzed, 86 of whom were treated with citicoline within the first 48 h after AIS and the remaining 87 were untreated, randomly selected controls matched for age (+/- 5 years), gender and NIHSS (+/- 1 point) at hospital admission. Pretreatment conditions were similar between groups. Compared with controls, exposure to citicoline was associated with a significantly lower 30-day mean and median modified Rankin score (in both, P < 0.05). After paired multivariate analyses (controlled for NIHSS, age, gender, hospital arrival in < 24 h, thrombolysis and comorbidities) citicoline was independently associated with a lower 90-day mortality risk (P = 0.047) and with fewer in-hospital complications (mainly infections and sepsis, P = 0.001). In this observational study, citicoline use was associated with a better functional status and lower rates of short-term mortality, possibly due to fewer in-hospital systemic complications. The putative benefits should be interpreted as clinical associations, since this is not a randomized, controlled clinical trial., (Copyright 2010 Prous Science, S.A.U. or its licensors.

Introduction: Parkinson disease (PD) is the second most common neurodegenerative disease of adult onset. Is a progressive movement disorder including tremor, bradykinesia, rigidity and postural instability, with an age onset between 43 and 66 years. Histopathologically, is characterized by a severe loss of dopaminergic neurons in the substantia nigra and inclusions consisting of insoluble protein aggregates called Lewy bodies, this are comprised in part of alpha-synuclein. The etiology of PD is still not fully understood, but genetic analyses, epidemiologic studies and experimental models of PD are providing important new insights into the pathogenesis of PD., Aim: To determine allelic and genotypic frequencies of polymorphism IVS4+66A-G in the alpha-synuclein gene and to demonstrate its association with PD in northwest Mexican population., Subjects and Methods: Genomic desoxyribonucleic acid (DNA) from 51 PD patients and 121 persons without PD were achieved by polymerase chain reaction and analyzed the allelic and genotypic distribution in IVS4+66A-G polymorphism of alpha-synuclein gene., Results: The genotypic frequency of IVS4+66AA was 43.1% in PD patients and 38.8% in control group; IVS4+66GG was 2% in PD patients and 4.1% in control group, whereas 54.9% in PD patients and 57.1% in control group were heterozygous. Statistical differences were not observed between groups (p<0.05)., Conclusions: Association was not observed between the IVS4+66A-G polymorphism and PD.

Introduction: 'Sword stroke' linear scleroderma, which is better known as linear scleroderma en coup de sabre (LSCS), is a rare disease with an uncertain causation that is characterised by progressive craniofacial focal atrophy and is, at least in part, different from Parry-Romberg syndrome (PRS)., Case Reports: Here, we report on the cases of 3 patients with LSCS (2 females and 1 male, with a mean age of 40 years). The main neurological symptoms were headache and seizures. Although different alterations were observed in the X-ray images, they were all ipsilateral to the coup de sabre. Histopathological evidence for gliosis and mixed perivascular inflammatory infiltrate was found in the study of a biopsy specimen taken from one female. Cerebrovascular involvement was seen in another patient, as highlighted by the observation of an earlier subclinical cerebellar infarct and occlusion of the superior cerebellar artery in the absence of any other possible causation., Conclusions: When it affects the central nervous system, the clinical and radiological presentation of LSCS is heterogeneous. Both the imaging studies carried out during the clinical control and the histopathological findings suggest a focal inflammatory process that can be progressive. The arterial involvement is probably due to a non-atherosclerotic, occlusive and chronic inflammatory disease of the peripheral vessels.

Introduction: Intracerebral haemorrhage (ICH) has received little attention in studies in Mexico. Isolated reports talk of high frequency, its importance as a disorder among young people, its being mainly located in the lobar regions and a high rate of recurrence., Aims: The objective of this study was to characterise the clinical, radiological, therapeutic and prognostic spectrum of ICH in a general hospital in the central-western region of Mexico., Patients and Methods: The study involved 270 consecutive patients over the age of 15 years with spontaneous ICH who were hospitalised in the Neurology and Neurosurgical Service in the Antiguo Hospital Civil de Guadalajara between the years 2000 and 2002. Their clinical history and progression was known at least on discharge from the hospital., Results: The mean age was 63 years (12% under 40 years old) with no predominance according to gender (53% males). Arterial hypertension was the main risk factor in 69%, followed by obesity in 38%. There were no differences in the Glasgow administered on admission in three pre-established subgroups. The ICH was ganglionic in 64% of cases and lobar in 24%. Arterial hypertension was the principal cause of ICH in 76%. Ventricular aperture was noted in 53%. All the patients were treated in a general ward. Mortality in the acute phase occurred in 49%, although a poor progression was observed in 83%. Overall recurrence was 13%. Outpatient follow-up was poor., Conclusions: ICH shares most of the features reported in Anglo-Saxon series including aetiology and location. In our population, mortality and recurrence are high with important sequelae. The high frequency of ICH (40%) may represent a bias in the selection of hospitals.

EEGs and behavioral responses were studied in two sex matched groups of 58 epileptic and 20 healthy children between 8 and 12 years of age, during the execution of a go-no go CPT (X; A-X) task to determine transitory cognitive impairment (TCI) incidence. Paroxysmal discharges were found on 87.9% and 5% of the EEGs in the epileptic and control groups respectively, with no differences related to sex. The predominant EEG findings with respect to paroxysmal discharges were the association of two or more types of paroxysms with frequency higher than 5/minute, an average duration less than 0.5 second and topographical distribution over temporal-parietal-occipital areas without significant interhemispheric differences. TCI was detected in 36.2% of epileptic children. The epileptic group showed significantly higher numbers of behavioral errors and longer reaction times (RTs) in relation to the control group. Analyzing RTs on the two blocks of the task, linear discriminant analysis showed an acceptable classification of TCI incidence between groups.

Hallervorden-Spatz disease (HSD) is an uncommon disorder, progressive and degenerative of the basal ganglia. It begins in the first or second decade of life and is characterized by a dominant extrapiramidal signs, dystonia and progressive dementia. It is autosomic recessive, although sporadic cases are seen in 15%. There is no biological marker for the disease. The post-mortem findings include iron deposits in the globus pallidum and pars reticulata of the substantia nigra. Magnetic resonance imaging (MRI) in T2 shows symmetric hypointense lesions in both globus pallidum with a hyperintense center: giving the "tiger's eye" sign. This is the first case reported in Mexico of sporadic HSD with typical clinical and MRI findings.
