Major depressive disorder affects about one in every 10 people in Mexico and is one of the first 5 causes of disability worldwide. Current treatment options are limited and only act upon some factors associated in its physiopathology. Moreover, the effects on depression are not immediate, which is a great limitation in obtaining a benefit over disability caused by this disorder and impedes a rapid action in the scenario of suicidality. Recently, ketamine (an anesthetic) has shown to have antidepressant properties by acting in the glutamate neurotransmission system (while no other current treatment acts on this level). It offers benefits in depressive symptoms in a matter of hours and has proven to be useful in patients that do not benefit from current therapeutic options. Recently, it has been approved for the treatment of depression. However, there are still many questions about its antidepressant mechanisms of action, safety, side effects, among others.

Background: Neuropsychiatric disorders represent one of the first causes of disability worldwide. Recognizing the main causes for hospitalization may allow the implementation of interventions to prevent hospitalization and promote ambulatory care. Objective: To describe the trends of mental disorders requiring hospitalization in a neuropsychiatric referral center of a middle-income country. Material and methods: Observational, cross-sectional, and analytic study. Information was obtained from dismissal letters and from the Department of Epidemiology database in a 16-year period at a neuropsychiatric referral center. Diagnoses and trends through this period were obtained using Spearman's correlation. Results: Schizophrenia represented most of the cases (19%), followed by bipolar disorder (13%). Psychotic disorders (PD) were found to contribute the most to the length of stay (43.76%), followed by mood disorders (MD) (39.07%). Schizophrenia-related dismissals diminished through the years (r = -751; p = 0.001), whereas depression-related disorders increased (r = 0.857; p < 0.001). Conclusions: PD are the first cause of neuropsychiatric hospitalization. MD have an increasing frequency of hospitalization. Longer-stay disorders reflect global and economic burden of disease trends. These results might guide interventions that reduce hospital-based models of care, which represent a great burden in low and middleincome countries. Studies aiming to explain the trends reported are needed. [ABSTRACT FROM AUTHOR]

This article addresses the work of Chilean poet Paulo de Jolly (1952). An enigmatic, little known figure in the Chilean poetry scene, De Jolly begun developing a poetic project in the '80s consisting in embodying the voice of King Louis XIV. Using comparative analysis, this article examines how, while his peers wrote -or tried to write- about torture and disappearances, Paulo de Jolly celebrated the ample gardens of the Palace of Versailles and glorified ideas regarding the will to live, the luminosity in spaces, and the mildness of life in the court.

This study aimed to demonstrate each joint angle at the maximum external rotation of the shoulder complex during the throwing of adolescent baseball players. The subjects were 15 adolescent baseball players (13.7±0.8 yrs) and 15 collegiate baseball players (22.1±1.5yrs). Throwing motion images were captured by three high-speed cameras, and a 3D analysis established by the direct leaner translation method was performed to obtain the shoulder external rotation, the glenohumeral external rotation (ER), and scapular posterior tilt angles. In the adolescent baseball players, the mean (±SD) value of the maximum external rotation angle (MER) was 141 ±15°, whereas the mean values of the glenohumeral ER and the scapula posterior tilt angles at the MER were 109±15° and 31±14°. Conversely, each angle of the college baseball players was 144±11°, 107±15°, and 29±14° respectively. There were no differences between the adolescent players and the college players. The adolescent players may need the same shoulder joint angles as the college players [ABSTRACT FROM AUTHOR]

El artículo trata el rol de los polimorfismos genéticos en la periodontitis. Afirma que la genética puede determinar la gravedad y grado de la periodontitis y que se está aplicando tecnología genética en el diagnóstico y tratamiento de esta enfermedad. Sugiere que la periodontitis puede explicarse en base a varias polimorfismos de alto riesgo que tienen perfiles de alta susceptibilidad.

El artículo trata el efecto del ligando del receptor activador del factor nuclear κB (RANKL) y de la osteoprotegerina en el periodonto. Explica que los dientes cuentan con un sistema inmunitario especial en el área donde se unen la raíz y la encía. Nota que, con la interrupción de la integridad epitelial, incrementan los linfocitos B y T y los macrófagos. Menciona que el RANKL aparece en los osteoblastos y en los linfocitos T activados.
