Objective: To examine whether objective sleep parameters are associated with cognitive function (CF) in patients with major depressive disorder (MDD) with chronic insomnia (CI) and whether the severity of these disorders is related to CF.

Method: Thirty patients with MDD with CI attending a tertiary care institution underwent two consecutive nights of polysomnographic (PSG) recording and a battery of neuropsychological tests, which included episodic memory, sustained attention, working memory, and executive function. The severity of MDD and CI was assessed by clinical scales.

Executive functions allow the regulation of behavior and emotions. This study aimed to analyze the association of executive functions with externalizing and internalizing behaviors in 30 Mexican preschoolers with typical development (age  = 53.63 months;  = 7.

Social abilities include interpersonal skills, interaction, and social responsibility. The nature of these abilities has not been explored in young people with Down syndrome (DS) during the social isolation of the COVID-19 pandemic. : The aim of this online study was to describe the social profile of a group of 30 Mexican people with DS, with a chronological age of 15-29 years, and explore the variables related to their psychosocial profiles.

Insects show remarkable phenotypic plasticity in response to changing environmental conditions. The abiotic factors that determine their phenotypes often vary in time and space, and oceanic islands harbour ideal environments for testing predictions on this matter. The ubiquitous beetle Wollaston, 1864 (Tenebrionidae) is distributed over the entire altitudinal gradient of the island El Hierro (Canary archipelago), from 0 to 1501 m above sea level.

Although it is self-evident that education in neurology is important and necessary, how to fund the educational mission is a frequent challenge for neurology departments and clinicians. Department chairs often resort to a piecemeal approach, cobbling together funding for educators from various sources, but frequently falling short. Here, we review the various sources available to fund the educational mission in neurology, understanding that not every department will have access to every source.

Background: Current risk-adjusted models used to predict donor heart use and cardiac graft survival from organ donors after brain death (DBDs) do not include bedside critical care data. We sought to identify novel independent predictors of heart use and graft survival to better understand the relationship between donor management and transplantation outcomes.

Study Design: We conducted a prospective observational study of DBDs managed from 2008 to 2013 by 10 organ procurement organizations.

Unlabelled: The objective of this study was to explore the prevalence of substance-induced neurocognitive disorder (NCD) in a sample of polysubstance users, adding both objective- and subjective cognitive impairment.

Method: We collected cross-sectional data from 33 community-based residential facilities in Mexico City. Montreal Cognitive Assessment was used for measurement of objective cognitive impairment, and a DSM-5-based interview for subjective impairment.

The objectives were to identify a latent factor of cognitive reserve (CR) assessed by self-rating of cognitively stimulating activities, to analyze the association between this factor and educational attainment, and to test whether CR moderates the association between polysubstance use and neurocognitive disorder (NCD). Cross-sectional data of 753 participants was collected in Mexico City. A questionnaire for self-rating of stimulating activities (work/education, leisure, physical, social, usual- and current environments) was designed.

Background: Meeting donor management goals when caring for potential organ donors has been associated with more organs transplanted per donor (OTPD). Concern persists, however, as to whether this indicates that younger/healthier donors are more likely to meet donor management goals or whether active management affects outcomes.

Study Design: A prospective observational study of all standard criteria donors was conducted by 10 organ procurement organizations across United Network for Organ Sharing Regions 4, 5, and 6.

Background: There is a national shortage of organs available for transplantation, and utilization rates for thoracic organs are less than 40%. In addition, the optimal method of assessing cardiovascular status during donor management is uncertain. FloTrac is a noninvasive hemodynamic technique that measures cardiac output and fluid responsiveness.

Background: A rhabdomyolysis protocol (RP) with mannitol and bicarbonate to prevent acute renal dysfunction (ARD, creatinine >2.0 mg/dL) remains controversial.

Methods: Patients with creatine kinase (CK) greater than 2,000 U/L over a 10-year period were identified.

Background: Historically, strategies to reduce acute rejection and improve graft survival in kidney transplant recipients included blood transfusions (BTs) before transplantation. While advents in recipient immunosuppression strategies have replaced this practice, the impact of BTs in the organ donor on recipient graft outcomes has not been evaluated. We hypothesize that BTs in organ donors after neurologic determination of death (DNDDs) translate into improved recipient renal graft outcomes, as measured by a decrease in delayed graft function (DGF).

Middle-aged individuals encounter multiple environmental demands to which they must develop efficient solutions, thus making the study of executive functions and coping strategies within this age group important. This study evaluated the relationship between the planning and flexible organization of executive function with adaptive coping strategies (ACS) in adults aged 43 to 52 years old. The study included 104 participants, including 52 men and 52 women, with no history of neurological or psychiatric illnesses, diabetes, or hypertension.

Importance: The shortage of organs available for transplant has led to the use of expanded criteria donors (ECDs) to extend the donor pool. These donors are older and have more comorbidities and efforts to optimize the quality of their organs are needed.

Objective: To determine the impact of meeting a standardized set of critical care end points, or donor management goals (DMGs), on the number of organs transplanted per donor in ECDs.

Background: The appropriate level of glucose control in organ donors after neurologic determination of death (DNDD) remains uncertain. We hypothesized that a glucose target of 180 mg/dL would be appropriate for optimizing organ transplantation rates and outcomes.

Methods: Demographic, critical care, organ transplantation, and graft outcome data were prospectively collected on all DNDDs in United Network for Organ Sharing (UNOS) Region 5 from 2010 to 2012.

We studied the effect of emotion generated by IAPS (International Affective Picture System) pictures on incidental recognition of these pictures for short retention periods (15 min). Memorization distraction tasks and reaction time tasks were used together with short exposure times (2 seconds per picture) in order to prevent a high recognition rate that would impede testing for the effect of emotion on discrimination parameters (A´) and response bias (B´´D) (ceiling effect). We used 80 pictures representing the medium and high levels of two-dimensional emotional space.

In order to explore if neuropsychological deficits on visual constructional ability could be related to risk eating behaviors, a total of 102 women were evaluated, 51 of the participants had been formally diagnosed with eating disorders and 51 did not. All participants were given the Eating Attitude Test (EAT-40), The Rey-Osterrieth Complex Figure and The Tower of London Task. Results revealed the existence of a deficit on visual integration similar to those observed in other studies with diagnosed patients.
