Selective arterial embolization as an alternative modality treatment prior to mandibular aneursymal bone cyst surgical curettage: Case report.

ABC (Aneurysmal bone cyst) is a rare, benign and osteolytic lesion. Diagnosis of ABC can be challenging because of its uncommon radiographic and clinical presentation. The case of an 8-year-old female with a rapidly growing painful swelling in her left mandible is presented.

Common surgical training program: standardization of learning quality.

Introduction: The various surgical specialties in our center have used the simulation and experimental surgery resources available for their training tasks in minimally invasive surgery (MIS) in an individualized manner. With this learning model, a great dispersion of effort and expense was observed, so it was decided to create a unified program based on the following: shared learning, synergy among specialties, moderation of the economic cost, and rational use of the facilities.

Objective: To describe and assess our consensually designed training program in order to consolidate a shared learning strategy that will enable our residents to acquire and perfect surgical skills in MIS.

Predicting caregiver burden over the first 4 months after acute traumatic brain injury in Latin America: a multi-country study.

: Traumatic brain injury (TBI) rates and outcomes are worse in Latin American countries relative to high-income countries. This study examined whether cognitive dysfunction, depressive mood, and poor social and emotional self-regulation in individuals with an acute TBI in Latin America predict longitudinal trajectories of caregiver burden during the first 4 months post-discharge.: A sample of 109 caregivers of individuals with a new TBI from Colombia and Mexico completed the observer European Brain Injury Questionnaire before hospital discharge and the Zarit Burden Inventory at the same time and again at 2 and 4 months after discharge.

Multivariate Base Rates of Low Scores on Tests of Executive Functions in a Multi-Country Latin American Sample.

The objective of the study was to determine the prevalence of low scores in a diverse Latin American population for two neuropsychological commonly used tests to evaluate executive functions and to compare the number of low scores obtained using normative data from a Spanish-speaking population from Latin America versus an English-speaking population from U.S.A.

A Multi-Site Study of Traumatic Brain Injury in Mexico and Colombia: Longitudinal Mediational and Cross-Lagged Models of Family Dynamics, Coping, and Health-Related Quality of Life.

Latin America has high rates of traumatic brain injury (TBI), yet reduced mental and physical health outcomes due to limited rehabilitation services. To understand the psychosocial adjustment process in TBI patients in Latin America, the incorporation of cultural values including family-based variables is imperative. The current study examined relations among healthy family dynamics, coping, and mental and physical health related quality of life (HRQL) among a sample of TBI patients across three sites and two countries over the first 4 months post-injury.

Relationship Satisfaction and Depression After Traumatic Brain Injury: An Actor-Partner Interdependence Model of Patients and Caregivers in Mexico and Colombia.

Objective: Traumatic brain injury represents a major public health concern, particularly in low- and middle-income countries like in Latin America. Family members are often caregivers for individuals with traumatic brain injury, which can result in significant stress. Research is needed to examine depression and quality of the caregiving relationship in these dyads.

Predictors of longitudinal depression trajectories after traumatic brain injury in Latin America: A multi-site study.

Background: Latin America has exceptionally high rates of traumatic brain injury (TBI), but very little research has been conducted on longitudinal TBI outcomes in this global region.

Objective: This study examined whether cognitive dysfunction and social disadaptation in individuals with TBI in Latin America at hospital discharge predict longitudinal trajectories of depression at baseline, 2 months, and 4 months.

Methods: A sample of 109 people with a new TBI was recruited from three hospitals: Mexico City, Mexico, Cali, Colombia and Neiva, Colombia.

The Association Between the Number of Neuropsychological Measures and the Base Rate of Low Scores.

Obtaining one or more low scores, or scores indicative of impairment, is common in neuropsychological batteries that include several measures even among cognitively normal individuals. However, the expected number of low scores in batteries with differing number of tests is unknown. Using 10 neuropsychological measures from the National Alzheimer's Coordinating Center database, 1,023 permutations were calculated from a sample of 5,046 cognitively normal individuals.

Health-Related Quality of Life and Mental Health of Adolescents Involved in School Bullying and Homophobic Verbal Content Bullying.

Bullying has been traditionally related to a significant reduction in well-being and Health-Related Quality of Life (HRQoL) of adolescents. This negative impact on HRQoL seems to be modulated by the developed role in bullying (uninvolved, bully, victim or bully-victim). However, no studies have identified if these negative results are the same when other types of bullying, such as homophobic bullying, are evaluated.

Trajectories of memory, language, and visuoperceptual problems in people with stroke during the first year and controls in Colombia.

Aim: Neuropsychological normative data for Latin America have been recently published, and for Colombia, in particular, but longitudinal neuropsychological outcomes after stroke have not yet been examined in this global region. The purpose of the current study was to compare functioning of individuals with stroke in Colombia, South America during the first year post-stroke to healthy controls across neuropsychological assessments of memory, language, and visuoperceptual impairments.

Method: A sample of 50 individuals with stroke (mean age = 51.

Global Outcome Trajectories up to 10 Years After Moderate to Severe Traumatic Brain Injury.

Based on important predictors, global functional outcome after traumatic brain injury (TBI) may vary significantly over time. This study sought to: (1) describe changes in the Glasgow Outcome Scale-Extended (GOSE) score in survivors of moderate to severe TBI, (2) examine longitudinal GOSE trajectories up to 10 years after injury, and (3) investigate predictors of these trajectories based on socio-demographic and injury characteristics. Socio-demographic and injury characteristics of 97 TBI survivors aged 16-55 years were recorded at baseline.

Employment Probability Trajectories Up To 10 Years After Moderate-To-Severe Traumatic Brain Injury.

To examine trajectories of employment probability up to 10 years following moderate-to-severe traumatic brain injury (TBI) and identify significant predictors from baseline socio-demographic and injury characteristics. A longitudinal observational study followed 97 individuals with moderate-to-severe TBI for their employment status up to 10 years post injury. Participants were enrolled at the Trauma Referral Center in South-Eastern Norway between 2005 and 2007.

Mediational Model of Multiple Sclerosis Impairments, Family Needs, and Caregiver Mental Health in Guadalajara, Mexico.

Individuals with multiple sclerosis (MS), especially those living in Latin America, often require assistance from family caregivers throughout the duration of the disease. Previous research suggests that family caregivers may experience positive and negative outcomes from providing care to individuals with MS, but few studies have examined the unmet needs of individuals providing care to family members with MS and how these unmet needs may mediate the relationship between MS symptoms and caregiver mental health. The current study examined the relationships among MS impairments (functional, neurological, cognitive, behavioral, and emotional), unmet family needs (household, informational, financial, social support, and health), and caregiver mental health (satisfaction with life, anxiety, burden, and depression) in a sample of 81 MS caregivers from Guadalajara, Mexico.

Multiple mediation path model of pain's cascading influence on physical disability in individuals with SCI from Colombia, South America.

Background: Research has begun to document the bivariate connections between pain in individuals with spinal cord injury (SCI) and various aspects of health related quality of life (HRQOL), such as fatigue, social functioning, mental health, and physical functioning.

Objective: The purpose of this study was to construct and test a theoretical path model illuminating the stage-wise and sequential (cascading) HRQOL pathways through which pain increases physical disability in individuals with SCI in a sample from Colombia, South America. It was hypothesized that increased pain would lead to decreased energy, which would lead to decreased mental health and social functioning, which both would lead to emotional role limitations, which finally would lead to physical role limitations.

Reciprocal Causation Between Functional Independence and Mental Health 1 and 2 Years After Traumatic Brain Injury: A Cross-Lagged Panel Structural Equation Model.

Objective: The research attempting to disentangle the directionality of relationships between mental health and functional outcomes after traumatic brain injury (TBI) is growing but has yielded equivocal findings or focused on isolated predictors or isolated outcomes. The purpose of the current study was to use cross-lagged panel and structural equation modeling (SEM) techniques to examine causality between comprehensive indices of mental health (depression, anxiety, and life satisfaction) and functional independence in a national sample of individuals with TBI over the first 2 years after injury.

Design: Participants were 4,674 individuals with TBI from the TBI Model Systems Database.

Geometry Shapes Propagation: Assessing the Presence and Absence of Cortical Symmetries through a Computational Model of Cortical Spreading Depression.

Cortical spreading depression (CSD), a depolarization wave which originates in the visual cortex and travels toward the frontal lobe, has been suggested to be one neural correlate of aura migraine. To the date, little is known about the mechanisms which can trigger or stop aura migraine. Here, to shed some light on this problem and, under the hypothesis that CSD might mediate aura migraine, we aim to study different aspects favoring or disfavoring the propagation of CSD.

Lagged and instantaneous dynamical influences related to brain structural connectivity.

Contemporary neuroimaging methods can shed light on the basis of human neural and cognitive specializations, with important implications for neuroscience and medicine. Indeed, different MRI acquisitions provide different brain networks at the macroscale; whilst diffusion-weighted MRI (dMRI) provides a structural connectivity (SC) coincident with the bundles of parallel fibers between brain areas, functional MRI (fMRI) accounts for the variations in the blood-oxygenation-level-dependent T2(*) signal, providing functional connectivity (FC). Understanding the precise relation between FC and SC, that is, between brain dynamics and structure, is still a challenge for neuroscience.

Association of type and location of BRCA1 and BRCA2 mutations with risk of breast and ovarian cancer.

Importance: Limited information about the relationship between specific mutations in BRCA1 or BRCA2 (BRCA1/2) and cancer risk exists.

Objective: To identify mutation-specific cancer risks for carriers of BRCA1/2.

Design, Setting, And Participants: Observational study of women who were ascertained between 1937 and 2011 (median, 1999) and found to carry disease-associated BRCA1 or BRCA2 mutations.

Angiogenic and innate immune responses triggered by PRP in tendon cells are not modified by hyperuricemia.

Background: hyperuricemia is becoming a critical medical problem, and a current focus of research. Uric acid is also a death cell associated stressor that may trigger innate immune responses via the synthesis of inflammatory and angiogenic proteins.

Purpose: to investigate the angiogenic/inflammatory protein profile of tendon cells treated with Platelet Rich Plasma (PRP), and to assess if there are any differences in synthesis of angiogenic/inflammatory cytokines between PRP-treated or hyperuricemic PRP-treated cells.
