Combined action of SAMe, Folate, and Vitamin B12 in the treatment of mood disorders: a review.

Mood disorders affect more than 500 million people around the world. In the last decade, their prevalence has increased, and many people suffer from nervousness, anxiety, and stress at least once in their lives. The incidence of mood disorders and anxiety increases during perimenopause or under stressful conditions. The social restrictions introduced during the COVID-19 pandemic have significantly increased the normal burden of psychological and psychic disorders. In moderate to severe cases, pharmacological treatment is currently recommended, while in mild disorders, especially in the initial phase, psychological therapy is preferable. It is known that several nutrients are crucial for brain function. Among them, folate (vitamin B9), cyanocobalamin (vitamin B12), and S-adenosyl-L-methionine (SAMe) have been shown to influence various neurobiological processes. Overall, the available evidence suggests that dietary supplementation with folic acid, vitamin B12, and SAMe can be beneficial for people with mild mood disorders

Teores de proteína bruta, extrato etéreo e minerais de gramíneas nativas Paspalum repens e Paspalum fasciculatum de ecossistemas de várzea do Baixo Amazonas, Pará, Brasil.

En un Inceptisol húmedos del campo experimental de la Amazonia baja (2°23? de latitud sur y 54°20? de longitud oeste, municipio de Monte Alegre, Pará, Brasil) de la Empresa Brasileira de Pesquisa Agropecuária (Embrapa-Amazonia Oriental), en julio de 2003 (final del período lluvioso), septiembre de 2003 (período seco) y enero de 2004 (comienzo del período lluvioso) se determinaron los contenido de proteína cruda (PC), estracto etereo (EE) y minerales en el forraje de Paspalum repens (Perimembeca) e Paspalum fasciculatum (Mori) procedentes de la zona de varzea. Se utilizó un factorial de dos (especies nativas de forraje) y tres épocas de crecimiento (final y comienzo del periodo lluviosa y época seca). Se encontraron diferencias (P < 0.05) para el contenido de PC de las especies, siendo más alto en Perimembeca (12.06%) que en Mori (6.65). El contenido de P en ambas gramíneas fue bajo. El contenido de Cu en la gramínea Mori fue adecuado en tanto épocas secas como húmedas. Los contenidos de Ca, K y Fe fueron bajos e influenciados por la época

A pecuária na Amazônia: a busca por um modelo sustentável.

A pecuária na Amazônia é responsabilizada pelo desmatamento, pela emissão de gases do efeito estufa, perda da biodiversidade e alterações no ciclo hidrológico. No entanto, atualmente, existem fortes evidências indicando que o processo da atividade pecuária na Amazônia Brasileira está em transformação. As recentes quedas nas taxas de desmatamento e aumento do rebanho mostram várias modificações que decorrem da efetiva aplicação da legislação ambiental, com a maior presença governamental e participação social, consolidada através do novo código florestal brasileiro, marco legal que estabeleceu as diretrizes atuais para as atividades produtivas. Além disso, a aplicação ambiental contribuiu para tirar os produtores da insegurança jurídica estabelecendo prazos para adequação ambiental. Outro fator importante é o aumento da regularização fundiária, através do programa governamental Terra Legal. O maior controle ambiental e fundiário aliado às inovações tecnológicas, como a integração lavoura/pecuária e ao uso das biotecnologias reprodutivas como inseminação artificial (IA) e inseminação artificial em tempo fixo (IATF) tem contribuído para modernização da pecuária na Amazônia com menor impacto ambiental

International Expert Opinions and Recommendations on the Use of Melatonin in the Treatment of Insomnia and Circadian Sleep Disturbances in Adult Neuropsychiatric Disorders

Introduction: Insomnia and circadian rhythm disorders, such as the delayed sleep phase syndrome, are frequent in psychiatric disorders and their evaluation and management in early stages should be a priority. The aim of this paper was to express recommendations on the use of exogenous melatonin, which exhibits both chronobiotic and sleep-promoting actions, for the treatment of these sleep disturbances in psychiatric disorders. Methods: To this aim, we conducted a systematic review according to PRISMA on the use of melatonin for the treatment of insomnia and circadian sleep disorders in neuropsychiatry. We expressed recommendations for the use of melatonin in psychiatric clinical practice for each disorder using the RAND/UCLA appropriateness method. Results: We selected 41 studies, which included mood disorders, schizophrenia, substance use disorders, attention deficit hyperactivity disorders, autism spectrum disorders, neurocognitive disorders, and delirium; no studies were found for both anxiety and eating disorders. Conclusion: The administration of prolonged release melatonin at 2–10 mg, 1–2 h before bedtime, might be used in the treatment of insomnia symptoms or comorbid insomnia in mood disorders, schizophrenia, in adults with autism spectrum disorders, neurocognitive disorders and during sedative-hypnotics discontinuation. Immediate release melatonin at &lt;1 mg might be useful in the treatment of circadian sleep disturbances of neuropsychiatric disorders

Changes of consultation-liaison psychiatry practice in Italian general hospitals: A comparative 20-year multicenter study

Introduction: Conducted under the auspices of the Italian Society of Consultation Liaison Psychiatry (SIPC) the aim of this study was to describe the characteristics of Consultation Liaison Psychiatry (CLP) activity in Italy (SIPC-2—2018) over the past 20 years by comparing with data from the first Italian nation-wide study (SIPC-1—1998). Methods: We collected data on CLP visits of 3,943 patients from 10 Italian hospitals over a period of 1 year. Data were compared with those from the SIPC-1 1998 study (4,183 participants). Patients were assessed with the same ad hoc 60-item Patient Registration Form recording information from five different areas: Sociodemographic, hospitalization-related, consultation-related, interventions and outcome. Results: Compared with participants from the previous study, SIPC-2-2018 participants were significantly older (d = 0.54) and hospitalized for a longer duration (d = 0.20). The current study detected an increase in the proportion of referrals from surgical wards and for individuals affected by onco-hematologic diseases. Depressive disorders still represented the most frequent psychiatric diagnosis, followed by adjustment and stress disorders and delirium/dementia. Also, CLP psychiatrists prescribed more often antidepressants (Φ = 0.13), antipsychotics (Φ = 0.09), mood stabilizers (Φ = 0.24), and less often benzodiazepines (Φ = 0.07). Conclusion: CLP workload has increased considerably in the past 20 years in Italy, with changes in patient demographic and clinical characteristics. A trend toward increase in medication-based patient management was observed. These findings suggest that the psychiatric needs of patients admitted to the general hospital are more frequently addressed by referring physicians, although Italian CLP services still deserve better organization and autonomy
