Incidence, and factors associated with moderate/severe pediatric traumatic brain injury in children aged 5-15 years in western, Mexico.

OBJECTIVE: The study objectives were to estimate the standardized incidence and evaluate factors associated with moderate/severe pediatric traumatic brain injury (p-TBI) in children aged 5-15 years in Western, Mexico. METHODS: The study was cross-sectional in design. We estimated the standardized incidence of moderate/severe p-TBI using the direct methods of the World Health Organization (WHO) standard populations. We utilized the Glasgow Coma Scale (GCS) to identify moderate/severe p-TBI patients (GCS ≤ 13). Logistic regression analysis was applied to evaluate variables associated with moderate/severe p-TBI. RESULTS: The standardized incidence of patients diagnosed with moderate/severe p-TBI was 31.0/100,000 person-years (95 % CI 28.7-33.4). According to age, the moderate/severe TBI group was included. A total of 254 (38.5 %) patients were aged 5-9 years, 343 (52.0 %) were aged 10-14 years, and 62 (9.5 %) were aged 15 years. Factors associated with moderate/severe TBI in the crude analysis were male sex (OR 5.50, 95 % CI 4.16-7.39, p < 0.001), primary school (OR 2.15, 95 % CI 1.62-2.84, p < 0.001), and falls (OR 1.34, 95 % CI 1.02-1.77, p = 0.035). Factors associated with moderate/severe p-TBI in the adjusted analysis were male sex (OR 6.12, 95 % CI 4.53-8.29, p < 0.001), primary school (OR 3.25, 95 % CI 2.31-4.55, p < 0.001), and falls (OR 1.78, 95 % CI 1.28-2.47, p < 0.001). CONCLUSION: The incidence of moderate/severe p-TBI in children aged 5-15 years in western Mexico in this study was higher than that in other studies. One of the biggest factors associated with moderate/severe p-TBI was male sex, specifically those with lower education levels and those who were prone to falls.

Sustained attention in schoolchildren with type-1 diabetes. A quantitative EEG study.

OBJECTIVE: Type-1 diabetes (T1D) is a disruptive metabolic disease that has an impact on neurodevelopment through its effects on the structure and function of the brain. One of the cognitive domains affected by T1D is sustained attention. The aim of this study was to analyze this process in children with T1D and compare their results to those of healthy controls. METHODS: Seventeen T1D children attending regular primary school and a similar group of healthy children matched by gender, age, handedness, and educational level were evaluated while identifying happy faces in a Go-NoGo task presented visually with simultaneous electrophysiological recording. RESULTS: Behavioral performance in the two groups was similar but, the T1D children showed greater prefrontal and frontoparietal spectral power in the theta and alpha bands, compared to controls. Distinct patterns of theta lateralization between groups were also observed, with a negative correlation between frontal power magnitudes in delta and theta and glycated hemoglobin levels. CONCLUSIONS: These results seem to reflect the early deleterious effects of T1D on neurodevelopment, which affects mainly attention allocation processes and the neurofunctional substrates that underlie them. SIGNIFICANCE: This phenomenon emphasizes the need for studies on neural-specific targets in which T1D affects neurodevelopment.

Structural Equation Modeling of Parkinson's Caregiver Social Support, Resilience, and Mental Health: A Strength-Based Perspective.

Only scant literature has focused on social support in Parkinson's disease (PD) caregivers, and no studies to date have examined resilience in this population, despite both variables having been shown to be important in other caregiving populations. As a result, the purpose of the current study was to construct and validate a theoretical structural equation model whereby social support is associated with higher levels of resilience in PD caregivers and increased resilience is related to decreased mental health symptoms. Two hundred fifty three PD caregivers from two clinics in the United States and Mexico completed self-report measures of these constructs. Results suggested that the hypothesized pattern was robustly supported with the structural equation model showing generally good fit indices. Higher levels of social support were associated with increased resilience, which in turn was associated with reduced mental health symptoms. Resilience partially mediated social support's effect on mitigating mental health symptoms. The model explained 11% of the variance in resilience and 35% in mental health symptoms. These findings have implications for future research on the development and tailoring of interventions to improve social support, resilience, and mental health in PD caregivers.

La distimia en el contexto clínico / Dysthymia in the Clinical Context

La distimia se define como un trastorno afectivo crónico que persiste por lo menos dos años en adultos y un a ño en adolescentes y niños. Según el DSM IV-TR, se clasifica en dos subtipos: la distimia de inicio temprano, antes de los 21 años, y la de inicio tardío después de los 21 años. Generalmente antes de los 21 años se puede observar trastornos de conducta, déficit de atención e hiperactividad y algunos síntomas vegetativos. Es importante distinguir tempranamente la distimia de otros tipos de depresión, a fin de brindar un tratamiento oportuno que atenúe el impacto continuo de síntomas caracterizados por pobre conciencia del estado de ánimo, pensamiento negativo, baja autoestima y anergia, lo que deteriora progresivamente la calidad de vida. La etiología es compleja y multifactorial, dados los variados mecanismos biológicos, psicológicos y sociales involucrados. Varias hipótesis tratan de explicar la etiología de la distimia; destacan la hipótesis genética que incluye además factores ambientales y la hipótesis aminérgica, que apunta a una deficiencia de serotonina, noradrenalina y dopamina en el sistema nervioso central. Desde nuestro punto de vista, no se puede concebir la distimia como un simple trastorno depresivo leve; es una entidad diferente caracterizada por un trastorno depresivo crónico que puede persistir toda la vida, con importantes repercusiones en la calidad de vida, tanto del sujeto que la padece como de sus familiares.

Dysthymia is defined as a chronic mood disorder that persists for at least two years in adults, and one year in adolescents and children. According to DSM IV-TR, Dysthymia is classified into two subtypes: early-onset, when it begins before 21 years-old, and late onset Dysthymia, when it starts after this age. Before age 21, symptoms of conduct disorder, attention deficit disorder and hyperactivity with a few vegetative symptoms are usually present. It is important to distinguish it from other types of depression, as earlier as possible. This would allow providing these patients with the appropriate treatment to attenuate the impact of symptoms, such as poor awareness of self-mood, negative thinking, low self-esteem, and low energy for social and family activities, which progressively deteriorate their life quality. The etiology of Dysthymia is complex and multifactorial, given the various biological, psychological and social factors involved. Several hypotheses attempt to explain the etiology of Dysthymia, highlighting the genetic hypothesis, which also includes environmental factors, and an aminergic hypothesis suggesting a deficiency in serotonin, norepinephrine and dopamine in the central nervous system. From our point of view, dysthymia cannot be conceived as a simple mild depressive disorder. It is a distinct entity, characterized by a chronic depressive disorder which could persist throughout life, with important repercussions on the life quality of both patients and families.
