Types of Psychiatric Beds and Mental Health Services in 16 Latin American Countries, 1990-2020.

OBJECTIVE: Latin America has undergone major changes in psychiatric services over the past three decades. The authors aimed to assess the availability of service data and changes in psychiatric services in this region during the 1990-2020 period. METHODS: The authors formed a research network to collect data on psychiatric service indicators gathered between 1990 and 2020 from national registries in Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Panama, Paraguay, Peru, and Uruguay. Indicators included psychiatric beds in psychiatric and general hospitals overall, for children and adolescents, and for forensic populations; residential beds for substance use treatment; treatment slots in residential facilities and day hospitals; and outpatient facilities. RESULTS: Data availability varied among countries, service indicators, and time points. The median prevalence of psychiatric beds decreased in psychiatric hospitals from 5.1 to 3.0 per 100,000 people (-42%) and in general hospitals from 1.0 to 0.8 (-24%). The median prevalence estimates of specialized psychiatric beds for children and adolescents (0.18) and for forensic populations (0.04) remained unchanged. Increases in prevalence were observed for residential beds for substance use treatment (from 0.40 to 0.57, 43% increase), available treatment slots in residential facilities (0.67 to 0.79, 17%), treatment slots in day hospitals (0.41 to 0.54, 32%), and outpatient facilities (0.39 to 0.93, 138%). CONCLUSIONS: The findings indicate that treatment capacity shifted from inpatient to outpatient and community care. Most countries had a bed shortage for acute psychiatric care, especially for children and adolescents and forensic patients. More comprehensive and standardized mental health service registries are needed.

Antifungal activity of Co(II) and Cu(II) complexes containing 1,3-bis(benzotriazol-1-yl)-propan-2-ol on the growth and virulence traits of fluconazole-resistant Candida species: synthesis, DFT calculations, and biological activity.

Relevant virulence traits in Candida spp. are associated with dimorphic change and biofilm formation, which became an important target to reduce antifungal resistance. In this work, Co(II) complexes containing a benzotriazole derivative ligand showed a promising capacity of reducing these virulence traits. These complexes exhibited higher antifungal activities than the free ligands against all the Candida albicans and non-albicans strains tested, where compounds 2 and 4 showed minimum inhibitory concentration values between 15.62 and 125 µg mL-1. Moreover, four complexes (2-5) of Co(II) and Cu(II) with benzotriazole ligand were synthesized. These compounds were obtained as air-stable solids and characterized by melting point, thermogravimetric analysis, infrared, Raman and ultraviolet/visible spectroscopy. The analysis of the characterization data allowed us to identify that all the complexes had 1:1 (M:L) stoichiometries. Additionally, Density Functional Theory calculations were carried out for 2 and 3 to propose a probable geometry of both compounds. The conformer Da of 2 was the most stable conformer according to the Energy Decomposition Analysis; while the conformers of 3 have a fluxional behavior in this analysis that did not allow us to determine the most probable conformer. These results provide an important platform for the design of new compounds with antifungal activities and the capacity to attack other target of relevance to reduce antimicrobial resistance.

Exploring the potential of eco-friendly silver nanoparticles to inhibit azole-resistant clinical isolates of Candida spp.

The antimicrobial activity and biological efficiency of silver nanoparticles (AgNps) have been widely described and can be modeled through stabilizing and reducing agents, especially if they exhibit biocidal properties, which can enhance bioactivity against pathogens. The selective action of AgNps remains a major concern. In this regard, the use of plant extracts for the green synthesis of nanoparticles offers advantages because it improves the toxicity of Nps for microorganisms and is harmless to normal cells. However, biological evaluations of the activity of AgNps synthesized using different reducing agents are determined independently, and comparisons are frequently overlooked. Thus, we investigated and compared the antifungal and cytotoxic effects of two ecological AgNps synthesized from Moringa oleifera aqueous leaf extract (AgNp-M) and glucose (AgNp-G) against azole-resistant clinical isolates of Candida spp. and nontumor mammalian cells. Synthesized AgNps exhibited an antifungal effect on planktonic cells of drug-resistant C. albicans and C. tropicalis (MIC 0.21-52.6 µg/mL). The toxicity was influenced by size. However, the use of M. oleifera extracts allows us to obtain AgNps that are highly selective and nongenotoxic to Vero cells due to modifications of the shape and surface. Therefore, these results suggest that AgNp-M has antimicrobial potential and deserves further investigation for biomedical applications.

Mental disorders in Mexico 1990-2021. Results from the Global Burden of Disease 2021 study.

BACKGROUND: Mental disorders are one of the main causes of years lived with disability, although there is a lack of recent estimates of their magnitude. OBJECTIVE: To report the trends of mental disorders prevalence, years lived with disability and years of healthy life lost by sex, age and state in Mexico. MATERIAL AND METHODS: The Global Burden of Disease database for Mexico was used. RESULTS: There were an estimated 18.1 million persons with some mental disorder in 2021, which represented an increase of 15.4% in comparison with 2019. Depressive and anxiety disorders did significantly increase between 2019 and 2021, which is possibly related to COVID-19, the confinement and the situations of grief experienced during the pandemic. CONCLUSIONS: Mental disorders have considerably increased since the only national mental health survey that used diagnostic criteria to evaluate their prevalence. It is important to invest in epidemiological studies, prevention and care of mental disorders, which are among the leading causes of years lived with disability in the country.

ANTECEDENTES: Los trastornos mentales constituyen una de las principales causas de años vividos con discapacidad, si bien no se dispone de estimaciones recientes sobre su magnitud. OBJETIVO: Reportar las tendencias de prevalencia de trastornos mentales, los años vividos con discapacidad y los años de vida saludables perdidos por sexo, edad y entidad federativa de México. MATERIAL Y MÉTODOS: Se utilizó la base de datos para México del Global Burden of Disease. RESULTADOS: Se calcularon 18.1 millones de personas con algún trastorno mental en 2021, que representaron un incremento de 15.4 % respecto a 2019. Los trastornos depresivos y de ansiedad aumentaron de manera notable entre 2019 y 2021, lo cual posiblemente esté relacionado con COVID-19, el confinamiento y los duelos vividos durante la pandemia. CONCLUSIONES: Los trastornos mentales se han incrementado considerablemente desde la única encuesta nacional de salud mental que utilizó criterios diagnósticos para evaluar las prevalencias. Es importante invertir en estudios epidemiológicos, prevención y atención de los trastornos mentales, los cuales se encuentran entre las primeras causas de años vividos con discapacidad en el país.

Nanoemulsions with Chloroaluminium Phthalocyanine and Paromomycin for Combined Photodynamic and Antibiotic Therapy for Cutaneous Leishmaniasis.

BACKGROUND: Photodynamic therapy (PDT) using chloroaluminium phthalocyanine (ClAlPc) and paromomycin sulfate (PM) can be effective against New World Leishmania species involved in cutaneous leishmaniasis (CL). The aim of this study is to assay the skin permeation and the antileishmanial effects of a nanoemulsion (NE) containing both ClAlPc and PM in experimental CL by Leishmania (Viannia) braziliensis. MATERIAL AND METHODS: Cremophor ELP/castor oil-based NEs were prepared by a low-energy method and characterized for their physicochemical parameters. The NEs were used to deliver both ClAlPc and PM to leishmania cells. The in vitro toxicity of NEs were tested in vitro against L. (V.) braziliensis and THP-1 cells. The in vivo toxicity was assessed in non-infected BALB/c mice. Ex-vivo permeation and retention studies using healthy mice skin were also conducted. Finally, the in vivo activity of NE-PM+ClAlPc after PDT was tested in BALB/c mice infected with parasites. RESULTS: NEs are colloidally stable with average droplet diameter of 30 nm, polydispersity index (PDI) below 0.2, and zeta potential near zero. Both promastigotes and intracellular amastigotes treated with NE-PM, NE-ClAlPc and NE-PM+ClAlPc were inhibited at >50%, >95%, >88%, respectively, after PDT with a phototoxic index (PI) >1.2. No skin ClAlPc permeation was observed. In contrast, PM skin permeation was 80-fold higher using PM-loaded NE formulation in comparison to aqueous PM solution. Topical treatment with NE formulations showed no signs of local toxicity or genotoxicity. In addition, concentrations of PM between 27.3 - 292.5 µM/25 mg of tissue were detected in different organs. In vivo, the NE-PM+ClAlPc treatment did not reduce skin lesions. CONCLUSION: The Cremophor ELP/castor oil NE formulation increases the permeation of PM through the skin and can be used to co-deliver PM plus ClAlPc for combined PDT protocols. However, the lack of efficacy in the in vivo model evidences that the therapeutical scheme has to be improved.

Inhibition of C. albicans Dimorphic Switch by Cobalt(II) Complexes with Ligands Derived from Pyrazoles and Dinitrobenzoate: Synthesis, Characterization and Biological Activity.

Seven cobalt(II) complexes of pyrazole derivatives and dinitrobenzoate ligands were synthesized and characterized. The single-crystal X-ray diffraction structure was determined for one of the ligands and one of the complexes. The analysis and spectral data showed that all the cobalt complexes had octahedral geometries, which was supported by DFT calculations. The complexes and their free ligands were evaluated against fungal strains of Candida albicans and emerging non-albicans species and epimastigotes of Trypanosoma cruzi. We obtained antifungal activity with a minimum inhibitory concentration (MIC) ranging from 31.3 to 250 µg mL-1. The complexes were more active against C. krusei, showing MIC values between 31.25 and 62.5 µg mL-1. In addition, some ligands (L1-L6) and complexes (5 and Co(OAc)2 · 4H2O) significantly reduced the yeast to hypha transition of C. albicans at 500 µg mL-1 (inhibition ranging from 30 to 54%). Finally, the complexes and ligands did not present trypanocidal activity and were not toxic to Vero cells. Our results suggest that complexes of cobalt(II) with ligands derived from pyrazoles and dinitrobenzoate may be an attractive alternative for the treatment of diseases caused by fungi, especially because they target one of the most important virulence factors of C. albicans.

La Terapia Centrada en Soluciones: Una opción de tratamiento para la dependencia al alcohol / Solution-focused therapy: An alcohol dependence treatment option

In Mexico, excess drinking constitutes one of the main public health challenges nationwide. The 2002 National Addictions Survey documented the existence of 11 035 262 heavy drinkers, 3 226 490 habitual drinkers, 2 841 303 persons with alcohol dependence and 2 343 71 0 persons who started arguing with their spouse or partner when drunk. Illnesses that are directly or indirectly associated with drinking are among the ten leading causes of death in Mexico among the general population: specifically, men die from attacks or homicide, self-inflicted wounds, alcoholic liver disease and other chronic diseases of the liver and alcohol dependence syndrome. Although there are various intervention strategies that attempt to influence this problem, it is not known whether these interventions are a causal factor in the change produced by the consumer and the way in which this change is produced after treatment; one way of determining this is by evaluating their results. Although Solution-Focused Therapy constitutes a different alternative to those that have traditionally been used for treating alcohol consumption, most research conducted in Mexico and other countries is carried out using a social learning model. Although the results of the Solution-Focused Therapy have been documented in various countries in America and the European Community, the findings are insufficient for it to be regarded as an optimal treatment for modifying excess alcohol consumption among the Mexican population. Objective To evaluate the results of the Solution-Focused Therapy in ethanol-dependent persons and to determine the differences between those that seek to modify problems associated with alcohol consumption and those that seek to change their drinking styles. Method A comparative O1-X-O2 longitudinal design was used, with a 12-month follow-up. The sample comprised 60 intentionally selected alcohol consumers, ages 18 to 50, who attended the Center of Assistance for Alcoholics and Their Relatives (CAAF) at the Ramón de la Fuente National Institute of Psychiatry. They had consumed alcohol in the past year, met the Alcohol Dependence Criteria according to the DSM-IV and gave their written consent. The sample was divided into 30 ethanol-dependent persons who attended the CAAF in an attempt to modify their drinking levels and 30 ethanol-dependent persons who sought to modify problems associated with their consumption. In this study, the results of the intervention were defined on the basis of the time elapsed between an ethanol-dependent person's last therapy session and the time when he or she experiences a relapse and continues with the problems associated with alcohol consumption. The subjects' history of alcohol consumption was characterized by their pattern of consumption, level of dependence, number of DSM-IV criteria, history of treatment, problems of alcohol consumption in the previous two generations of their families of origin, and alcohol-related problems. The number of additional sessions, services and treatments were regarded as mediators of the results of the intervention. The information was obtained through various instruments, such as the pre-consultation and initial consultation cards, the Scale of Ethanol-Dependence and a version of the Index of the Severity of Addiction drawn up by the Center of Assistance for Alcoholics and their Relatives. The procedure was carried out in three stages: the baseline, the application of Solution-Focused Therapy and a follow-up beginning twelve months after the last therapy session. The field operation began in April 2002 and ended in August 2004, with the last phase being carried out on both the subjects that had completed their treatment and on those that had interrupted it and requested assistance again at any of the services offered by the CAAF. Results Seventy-eight per cent of the sample were married; 38% had completed elementary school; the average age was 35.5, and most had a low socio-economic level. A total of 39% were heavy drinkers; 43% displayed a substantial level of dependence, and 70% had a record of treatment. The highest need for treatment was recorded in family problems associated with alcohol consumption, totaling 48%. Sixty-three per cent of the sample attended one to three sessions, while the remainder attended over three. A follow-up study of 83% of the sample showed that most sought assistance at two of the Center's treatment services, while 55% of the dependents received treatment at the CAAF alone. Thirty per cent cut short their treatment because they did not want to stop drinking or did not need help or were annexed; 28% stopped for work or financial reasons, while only 2% reported that the treatment failed to cover their expectations. Fifty-six per cent of the sample did not relapse, and successfully modified the problems associated with alcohol consumption; 32% relapsed and failed to modify their alcohol-related problems, while the remainder relapsed yet managed to modify the problems associated with alcohol consumption (12%) with a value of χ² = 29.94 and p equivalent to 0.00. The heterogeneity tests did not display statistically significant differences between the subjects that relapsed and continued with their alcohol-related problems (44%) and those that did not relapse and modified their alcohol-related problems (56%) by either alcohol consumption characteristics or the factors mediated by the results of the intervention. The study showed that the first four months after the last therapy session are those during which subjects experience the highest risk of relapsing and continuing with problems associated with alcohol consumption. Just 47% of the patients that cited modifying their drinking levels as the reason for seeking treatment proved not to have relapsed and to have successfully modified the problems associated with their drinking at the 1 2-month follow-up as opposed to 83% of those that sought to modify the problems associated with their drinking, with a statistical significance of less than 0.01 in the log-rank test. The intervention was observed to achieve better results among alcohol-dependent persons that sought to modify problems associated with alcohol consumption, had a lower socio-economic level, a record of treatment for their alcohol consumption, high levels of dependence, a medium-high need for treatment in psychological, work problems, and did not receive any form of treatment outside the CAAF. The article discusses the role of the demand for treatment as a predictor not only of the search for services, as supported by international literature, but also of the results of the intervention. It confirms the importance of conceiving alcoholism as a symptom resulting from relational systems the drinker maintains with his/her surroundings, rather than as a problem that can be solved by ensuring that the drinker remains sober. The article suggests including a control group with another type of therapeutic intervention in order to compare the results of the Solution-Focused Therapy and have more elements for making evidence-based decisions.

En México, el consumo excesivo de alcohol representa uno de los principales retos de salud pública a escala nacional. Aunque existen diversas estrategias de intervención que pretenden incidir en este problema también hay un gran vacío con respecto a si dichas intervenciones son un factor causal en el cambio producido por el consumidor y la manera en que dicho cambio se produce después del tratamiento. Una vía para conocerlo es evaluar sus resultados. La Terapia Centrada en Soluciones (TCS) constituye una alternativa a las que tradicionalmente se utilizan para tratar el consumo de alcohol. Sus resultados se han documentado en diferentes países de América y de la Comunidad Europea, pero no en población hispana. Objetivo Evaluar los resultados de la Terapia Centrada en Soluciones en dependientes al etanol y determinar las diferencias entre quienes buscaban modificar los problemas asociados al consumo de alcohol y los que pretendían cambiar su manera de beber. Método Se trabajó con un diseño longitudinal de tipo O1-X-O2, comparativo, con un seguimiento a doce meses. La muestra se integró con 60 consumidores de alcohol de 18 a 50 años de edad que acudieron al Centro de Ayuda al Alcohólico y sus Familiares (CAAF) del Instituto Nacional de Psiquiatría Ramón de la Fuente. Todos fueron seleccionados de manera intencional, consumieron alcohol en el último año, cubrieron los criterios de dependencia al alcohol según el DSM-IV y brindaron por escrito su consentimiento informado. La muestra se dividió en 30 dependientes al etanol que acudieron al CAAF en busca de modificar su nivel de consumo y 30 dependientes que pretendían modificar los problemas asociados a su consumo. En la presente investigación, los resultados de la intervención se definieron a partir del tiempo transcurrido desde que un dependiente asistía a la última sesión de terapia hasta que presentaba una recaída y continuaba con los problemas asociados al consumo de alcohol. La historia de consumo de alcohol de los sujetos se caracterizó por medio del patrón de consumo, nivel de dependencia, número de criterios del DSM-IV, antecedentes de tratamiento, problemas de consumo de alcohol en la familia de origen en dos generaciones previas y problemas asociados al consumo de alcohol. El número de sesiones, servicios y tratamientos adicionales se consideró como mediador de los resultados de la intervención. Resultados Del total de la muestra, 78% era casado; 38% tenía instrucción básica; la edad promedio fue de 35.5 años; la mayoría pertenecía a un nivel socioeconómico bajo; 39% era consumidor de alto nivel; 43% se ubicó en un nivel de dependencia sustancial y 70% contaba con antecedentes de tratamiento. La necesidad de tratamiento más alta se registró en los problemas familiares asociados al consumo de alcohol con 48%. Del total de la muestra, 63% asistió de una a dos sesiones y los restantes asistieron a más de dos, con un seguimiento de 83% de la muestra. En el análisis de sobrevida, los primeros cuatro meses después de tratamiento se identificaron como los meses de mayor riesgo para recaer. Se observó que la TCS tuvo mejores resultados en dependientes que buscaban modificar los problemas asociados al consumo de alcohol. Éstos se ubicaron en los niveles socioeconómicos más bajos y presentaron un nivel de deterioro importante por el consumo de alcohol.
