Exploration of the Severity of Hepatic Encephalopathy Deterioration Process Through Dynamics of the EEG Band Power time series.

Cirrhosis is a liver disease that could impair the functionality of the neural system, limiting cognitive processes and reduce mobility, possibly because alterations on dynamics of neural communications. In this study the dynamics of band power fluctuations on ß and γ bands were studied on three groups: control, patients with cirrhosis and patients diagnosed with minimal hepatic encephalopathy. EEG signals were recorded on an oddball paradigm and analyzed to obtain the latency and amplitude of the P300 wave and Detrended Fluctuation Analysis (DFA) exponent values over ß and γ band power time series for each channel.

Parasomnias related to shift work disorder among medical residents during the first year of training in Mexico.

Shift work disorder (SWD) may affect medical residents because their workload, academic demands and extended work hours. This condition set residents at risk of more sleep disorders. The study compared parasomnias among residents with and without shift work disorder (SWD) and weighed their relative risk (RR) for each parasomnia.

Chronic viral hepatitis C micro-elimination program using telemedicine. The Mexican experience.

Background: hepatitis C virus (HCV) infection is a global health problem. Chronic infection induces the development of fibrosis and cirrhosis together with all the related complications. The use of direct-acting antiviral (DAA) drugs has proven highly effective.

Differential production of insulin-like growth factor-binding proteins in liver fibrosis progression.

Noninvasive methods for liver disease diagnoses offer great advantages over biopsy, but they cannot be utilized in all cases. Therefore, specific indicators for chronic liver disease management are necessary. The aim was to assess the production of insulin-like growth factor-binding proteins (IGFBPs) 1-7 and their correlation with the different stages of fibrosis in chronic hepatitis C (CHC).

A low frequency of post infection-IBS in patients attended in a tertiary referral center in México.

Background: PI-IBS prevalence is around 10.1%-14.5% ≥ 12 months after infectious gastroenteritis in North America, Europe and Asia.

Error related negativity and multi-source interference task in children with attention deficit hyperactivity disorder-combined type.

Objective: To compare performance of children with attention deficit hyperactivity disorders-combined (ADHD-C) type with control children in multi-source interference task (MSIT) evaluated by means of error related negativity (ERN).

Method: We studied 12 children with ADHD-C type with a median age of 7 years, control children were age- and gender-matched. Children performed MSIT and simultaneous recording of ERN.

A middle-aged female serial killer.

The case of a 48-year-old woman accused of killing at least 12 elderly women and attempting to kill another one during the last 3 years is presented. Extensive neuropsychological, electrophysiological, and neuropsychiatric testing showed no evidence of a DSM-IV-TR Axis I diagnosis, but a decrease in executive functions and abnormalities in the processing of affective stimuli were found. Behavioral and psychophysiological studies revealed dissociation between knowing how to behave and actually behaving in socially acceptable ways.
