Mapping the research landscape of bauxite by-products (red mud): An evolutionary perspective from 1995 to 2022.

The global population growth has significantly impacted energy and raw material consumption, unmatched since the Industrial Revolution. Among metals, aluminium ranks second only to steel, with annual production exceeding 69 million tonnes. Due to its high demand, bauxite, the primary ore from which aluminium is extracted, is now classified as a critical material in the EU and the US, given the potential risk of supply shortages for essential applications.

Motivational enhancement treatment in outpatient addiction centers: A multisite randomized trial.

Background/objectives: Motivational Enhancement Treatment in Spanish (METS) is a brief intervention aimed at resolving patient ambivalence towards behavior change that has demonstrated efficacy in substance use disorder treatment to reduce use and increase treatment engagement in different populations. In order to have evidence for its implementation in Mexico, a multi-site, randomized, two-arm, controlled clinical trial was conducted at three outpatient addiction treatment centers in the country to compare the effect of METS with Counseling as Usual (CAU).

Method: One hundred and twenty patients were randomized to receive three sessions of METS ( = 54) or CAU ( = 66) during the first four weeks of treatment and were assessed during the following 12 weeks.

Technology transfer for the implementation of a clinical trials network on drug abuse and mental health treatment in Mexico.

Low- and middle-income countries (LMIC) lack the research infrastructure and capacity to conduct rigorous substance abuse and mental health effectiveness clinical trials to guide clinical practice. A partnership between the Florida Node Alliance of the United States National Drug Abuse Treatment Clinical Trials Network and the National Institute of Psychiatry in Mexico was established in 2011 to improve substance abuse practice in Mexico. The purpose of this partnership was to develop a Mexican national clinical trials network of substance abuse researchers and providers capable of implementing effectiveness randomized clinical trials in community-based settings.

Altered subcellular distribution of the 75-kDa DISC1 isoform, cAMP accumulation, and decreased neuronal migration in schizophrenia and bipolar disorder: implications for neurodevelopment.

Background: DISC1 (Disrupted-In-Schizophrenia-1) is considered a genetic risk factor for schizophrenia (SZ) and bipolar disorder (BD). DISC1 regulates microtubule stability, migration, and cAMP signaling in mammalian cell lines and mouse brain tissue. cAMP is a regulator of microtubule organization and migration in neurons.

Validation of the Impulsive/Premeditated Aggression Scale in Mexican psychiatric patients.

Introduction: Aggression has been linked to several psychiatric disorders. None of the available instruments validated in Mexico is able to classify aggression as impulsive or premeditated. The Impulsive/Premeditated Aggression Scale (IPAS) is a self-report instrument designed to characterize aggressiveness as predominately impulsive or premeditated.

Melatonin attenuates antipsychotic metabolic effects: an eight-week randomized, double-blind, parallel-group, placebo-controlled clinical trial.

Objective: Second-generation antipsychotics (SGAs) are among the first-line treatments for bipolar disorder and schizophrenia, but have a tendency to generate metabolic disturbances. These features resemble a metabolic syndrome for which a central autonomic imbalance has been proposed that may originate from the hypothalamic suprachiasmatic nuclei. In a clinical trial, we hypothesized that melatonin, a hormone that regulates the suprachiasmatic nucleus, could attenuate SGA-induced adverse metabolic effects.

[Translation into Spanish and validation of the Snaith-Hamilton Pleasure Scale (SHAPS) for anhedonia].

Introduction: The inability to experience pleasure, anhedonia, is recognized as al hallmark symptom of depression. A 14-item, self-report scale developed for the assessment of hedonic capacity: the Snaith-Hamilton Pleasure Scale (SHAPS) has proved to be a reliable and valid psychometric instrument.

Objective: Because there are no versions of the scale in other languages, our objective in this study was to translate the instrument into spanish and to determine if the new version maintained the validity and reliability of its original english version.

Mental illness recognition and beliefs about adequate treatment of a patient with schizophrenia: association with gender and perception of aggressiveness-dangerousness in a community sample of Mexico City.

Background: In developing countries, little is known about public recognition and beliefs about treatment of severe mental disorders, both emergent key elements in reducing stigma and the gap of treatment of such patients. It has been proposed that they may be related to gender and perception of patient's aggressiveness and/or dangerousness.

Aims: To assess mental illness recognition and beliefs about treatment of schizophrenia, and to determine their relationship with perception of patient's aggressiveness/dangerousness and gender of the perceiver in a community sample of Mexico City.

Immune variations in bipolar disorder: phasic differences.

Objectives: To characterize the immunological variations of patients with a bipolar disorder (BD) diagnosis in manic (BDm) and depressive (BDd) phases, by the quantification of the serum levels of interleukin (IL)-1beta, -2, -4, -6 and tumor necrosis factor alpha (TNF-alpha).

Methods: Twenty physically healthy patients with a BD type I diagnosis and 33 matched controls were studied, after giving informed consent. The inclusion criteria included at least three weeks without any kind of psychopharmacological treatment, Young Mania Rating Scale score > or =20 for BDm (n = 10) and Hamilton Depression Rating Scale score > or =21 for BDd patients (n = 10).

Acute exercise reduces the effects of a 35% CO2 challenge in patients with panic disorder.

Background: Chronic exercise has been shown to have therapeutic effects in panic disorder (PD). The mechanism of these effects is unknown. Acute exercise reduces the effect of a panic challenge in healthy volunteers.

Different gender response to serotonergic and noradrenergic antidepressants. A comparative study of the efficacy of citalopram and reboxetine.

Background: It is well established that depressive disorders are more prevalent in women; however gender differences in the pharmacological response to antidepressants are not a consistent finding in all reports. It is considered that this discrepancy can be explained by the fact that in most clinical trials drug use for comparative purposes is not completely different. In this study gender differences in antidepressant response with citalopram (CTP), a selective serotonin reuptake inhibitor and reboxetine (RBX), a selective noradrenaline reuptake inhibitor were evaluated in a group of young men and premenopausal women.

Failure of tibolone to potentiate the pharmacological effect of fluoxetine in postmenopausal major depression.

Background: Perimenopausal depression has been attributed to physiological progressive estrogen decline. Estrogen and derivatives have some mood-enhancing effects, although studies of using estrogen as an antidepressant have had mixed results. The gonadomimetic drug tibolone stimulates estrogen receptors in a tissue-selective fashion, increasing the gonadal activity without causing some of the usual side effects of other estrogen preparations.
