Are older adults also at higher psychological risk from COVID-19?

OBJECTIVE: Given the lack of information on the psychological impact of COVID-19 on people aged ≥60, we aimed to describe their psychological responses to this pandemic and lockdown situation and compare them with those under 60 years of age. METHODS: Secondary analysis of a larger online cross-sectional study designed to determine the psychological impact of the COVID-19 pandemic and lockdown across Spain. We analyzed a total of 1690 respondents aged ≥60 years and compared them with 13,363 respondents under 60 years of age. We employed the Depression, Anxiety, and Stress Scale and the Impact of Event Scale to evaluate psychological responses. RESULTS: In all, 52.6% of women and 34.3% of men were found to be probable cases of any emotional distress (p < 0.001). In both sexes, the most common psychological response was avoidance behavior (34.7% and 23.8%, respectively), followed by depression (28.5 and 14.2%). Older women and men were considered probable cases of any emotional distress less often than younger ones (women: 52.6% vs. 72.3%, p < 0.001; men: 34.3% vs. 50.6%, p < 0.001). Finally, the results of the binary logistic regression showed that only depressive and stress responses are psychological factors associated with age group [age ≥ 60 years, O.R. = 0.617 (95% CI = 0.501 - 0.759) and 0.437 (95% CI = 0.334 - 0.573), respectively]. CONCLUSION: Contrary to our hypothesis and despite the high percentage of emotional distress we found in older adults, especially women, they are actually at lower risk of developing depressive and stress consequences from COVID-19 and lockdown than those under 60 years of age. That said, we believe our results highlight the need for expert guidance in this age group, especially older women living alone.

Validation of a European Spanish adaptation of the Apathy Evaluation Scale-self-rated version (AES-S) in patients with schizophrenia.

INTRODUCTION: Apathy is a negative symptom of schizophrenia and is associated with poor real world functioning. Therefore, it is important to have validated psychometric instruments to assess this symptom. This is the first study to validate the Spanish adaptation of the self-rated version of the Apathy Assessment Scale (AES-S) in patients with schizophrenia. MATERIALS AND METHODS: Naturalistic, cross-sectional, validation study in 104 patients with schizophrenia evaluated using the following scales: Clinical Global Impression-Severity (CGI-S), Personal and Social Performance (PSP), Clinical Assessment Interview for Negative Symptoms (CAINS), Self-report of Negative Symptoms (SNS), Motivation and Pleasure Scale-Self-Report (MAP-SR), Calgary Depression Scale for Schizophrenia (CDSS), and Apathy Evaluation Scale-self-rated version (AES-S). RESULTS: Reliability: Internal consistency (Cronbach's alpha) was 0.908. Convergent validity: The Pearson correlation coefficient between AES-S and CAINS-MAP total scores was -0.483 (p<0.001). For SNS, total and avolition subscale scores were -0.803 and -0.639 (p<0.001), respectively. With the MAP-SR, the correlation coefficient was -0.727 (p<0.001). Divergent validity: The Pearson correlation coefficient between AES-S and PSP total scores was 0.504 (p<0.001). Furthermore, with the CDSS, the correlation coefficient was -0.431 (p<0.001). Discriminant validity: The AES-S discriminated between different levels of illness severity according to CGI-S scores. Factor analysis: A three-component solution explained 57.32% of the variance. Pearson correlations between coefficients were 1-2=0.265, 1-3=0.464, and 2-3=0.060. CONCLUSION: The Spanish AES-S is a reliable and valid instrument for assessing apathy in Spanish patients with schizophrenia. It seems to be appropriate for use in everyday clinical practice as a means of monitoring apathy in these patients.

Glutamine and New Pharmacological Targets to Treat Suicidal Ideation.

Glutamate is the major excitatory neurotransmitter in the central nervous system, and it is linked with the amino acid glutamine through a metabolic relationship of enzymatic compound interconversion and transportation, also known as the glutamate-glutamine cycle.A growing body of evidence suggests involvement of the glutamatergic neurotransmitter system in suicidal behaviours. The initial evidence comes from the pathophysiology of neuropsychiatric disorders, as disruptions in glutamate neurotransmission have been found underlying pathology in multiple suicide-related psychiatric conditions such as major depressive disorder, schizophrenia, post-traumatic stress disorder, and bipolar disorder.Existing data from experimental animal models and human in vivo studies also demonstrate that glutamate plays a key role in suicide-related personality traits including aggression and impulsive aggression.Further studies on glutamate system dysfunction underlying suicidal behaviours have focused on the different steps of the glutamate-glutamine cycle: an inflammation-mediated reduction of glutamine synthetase activity has been found in depressed suicide attempters, phosphate-activated glutaminase genes are reduced in suicide completers, and gene expression abnormalities in NMDA receptors have also been discovered in suicide victims.Evidence of a role of the glutamate-glutamine cycle in suicidal behaviours unveils new targets for anti-suicide interventions. Lithium's mechanism to reduce the risk of suicide in people with mood disorders may be related to its ability to increase glutamine synthetase, whereas novel NMDA antagonists such as ketamine [or its S(+) enantiomer esketamine] have already demonstrated positive results in reducing suicidal ideation.

Clinical staging in severe mental disorders; bipolar disorder, depression and schizophrenia. / Estadificación clínica en los trastornos mentales graves: trastorno bipolar, depresión y esquizofrenia.

Clinical staging is a diagnostic tool used in other medical specialties, which has resulted from the combination of a categorical and dimensional approach. In the last 2decades, the usefulness of its application in the field of psychiatry has been suggested, mainly as a tool for diagnostic help, and therapeutic and prognostic orientation. In this paper we review the clinical staging models that have been proposed to date for bipolar disorder, depression and schizophrenia. A literature search was performed in PubMed and Medline databases. A total of 15 studies were selected according to inclusion and exclusion criteria. Models were grouped according to the type of disorder for which staging was proposed (bipolar disorder: 4, depression: 5, schizophrenia: 6), and their characteristics were described. As a conclusion, we identify the need to empirically validate these models to demonstrate that staging is a useful tool for clinical practice.

It is feasible and effective to help patients with severe mental disorders to quit smoking: An ecological pragmatic clinical trial with transdermal nicotine patches and varenicline.

Despite the proven association between smoking and high rates of medical morbidity and reduced life expectancy in people with severe mental disorders (SMD), their smoking rates do not decline as they do in the general population. We carried out a non-randomized, open-label, prospective, 9-month follow-up multicentre trial to investigate the clinical efficacy, safety and tolerability of a 12-week smoking cessation programme for patients with SMD in the community under real-world clinical conditions. Eighty-two adult outpatients with schizophrenic/bipolar disorder smoking ≥15 cigarettes/day were assigned by shared decision between doctors and patients to transdermal nicotine patches (TNP) [36(46.2%)] or varenicline [39(50%)]. Short-term efficacy: The 12-week 7-day smoking cessation (self-reported cigarettes/day=0 and breath carbon monoxide levels≤9ppm) prevalence was 49.3%, without statistically significant differences between medications (TNP 50.0% vs varenicline 48.6%, chi-square=0.015, p=1.000). Long-term efficacy: At weeks 24 and 36, 41.3 and 37.3% of patients were abstinent, with no statistically significant differences between treatments. Safety and Tolerability: no patients made suicide attempts/required hospitalization. There was no worsening on the psychometric scales. Patients significantly increased weight [TNP 1.1(2.8) vs varenicline 2.5(3.3), p=0.063], without significant changes in vital signs/laboratory results, except significant decreases in alkaline phosphatase and low-density lipoprotein-cholesterol levels in the varenicline group. Patients under varenicline more frequently presented nausea/vomiting (p<0.0005), patients under TNP experienced skin reactions more frequently (p=0.002). Three patients under varenicline had elevated liver enzymes. In conclusion, we have demonstrated that in real-world clinical settings it is feasible and safe to help patients with stabilized severe mental disorders to quit smoking.

Estadificación clínica en los trastornos mentales graves: trastorno bipolar, depresión y esquizofrenia / Clinical staging in severe mental disorders; bipolar disorder, depression and schizophrenia

La estadificación clínica es una herramienta diagnóstica utilizada en otras especialidades de la medicina que surge de la combinación de un enfoque categorial y dimensional. En las últimas 2 décadas, se ha planteado su aplicación en el campo de la psiquiatría, fundamentalmente como herramienta de ayuda diagnóstica, de orientación terapéutica y pronóstica. En este trabajo se revisan los modelos de estadificación clínica que han sido propuestos hasta la fecha para el trastorno bipolar, la depresión y la esquizofrenia. Se realizó una búsqueda bibliográfica en las bases de datos PubMed y Medline. Se seleccionaron con base en los criterios de inclusión y exclusión un total de 15 estudios. Se describen y comparan las características de cada uno de los modelos agrupados según el tipo de trastorno para el que fueron propuestos (trastorno bipolar: 4; depresión: 5; esquizofrenia: 6). Como conclusión, identificamos la necesidad de validar empíricamente dichos modelos para así demostrar que son una herramienta útil en la práctica clínica habitual

Evolución histórica del uso y abuso de MDMA / Historical development of MDMA use and abuse

La MDMA (éxtasis), es sin duda, la droga que mayor popularidad ha alcanzado durante la última década. A pesar de haber sido sintetizada en 1912, no es hasta finales de los años 70 cuando comienza a ser utilizada por diversos grupos poblacionales en Estados Unidos (estudiantes, yuppies, gays y new agers). En el año 1985 es incluida en la Lista I de la Comprehensive Substances Act americana y en el año 1986, la OMS la incluye en la Lista I del Convenio sobre Psicotrópicos. Su posterior gran expansión a escala mundial se ha asociado a determinadas subculturas musicales y de ocio. En España, su difusión ha pasado por cinco fases diferentes: fase previa (1978-1986), fase inicial (1987-1989), fase de popularización (1990-1991), fase de vulgarización y consumo masivo (1992-1996) y fase de rutina y agotamiento del ciclo o fase de estabilización (1997-). Durante los últimos años existe cada vez mayor interés por parte de organismos internacionales y nacionales en la puesta en marcha de acciones conjuntas dirigidas a conocer la verdadera magnitud epidemiológica del fenómeno, sus consecuencias sobre la salud y en la puesta en marcha de acciones dirigidas a aminorar los potenciales daños asociados a su consumo (AU)

MDMA (ecstasy) has undoubtedly been the most popular recreational drug during the last decade. In spite of its having been synthesised in 1912 it was not employed as a drug by different groups in the United States until the end of the seventies (students, yuppies, gays, and new agers). In 1985 it was included in List I of the Amercican Comprehensive Substances Act, and in 1986, the WHO included it in List I of the Psychotropic Convention. Its greater spread on a worldwide bases has been associated with specific musical and recreational subcultures. In Spain, its spread has been over 5 different phases: previous phase (1978-1986), initial phase (1987-1989), popularity phase (1990-1991), phase of common use and masive consumption (1992-1996), and routine and end of cycle or stabilisation phase (1997-). During the last few years a considerable interest has been shown by international and national organisations to begin joint actions in order to know the real epidemiological magnitud of the phenomenon, its consequences on health, and the development of preventive actions to ameliorate the potential risks associated with its consumption (AU)
