Support the frontliners - Good initiatives during the COVID-19 pandemic for healthcare workers across the world: Is this what we really need?

Healthcare workers have faced an unprecedented workload in overstretched health facilities during the COVID-19 pandemic, and we describe various initiatives to support them. Psychological, financial and peer support, accommodation and meal services, proper personal protective equipment, applause and gratitude in the community, spiritual and religious life, child care and volunteering were identified. The potential effects of the COVID-19 pandemic - permanent stress, burnout and other mental health problems among healthcare professionals - can be expected to grow. Continued monitoring is essential to bolster resilience among healthcare workers and prevent the possible consequences for their mental health. Copyright © The Author(s), 2022.

Covid-19-induced psychosis: New challenges for early career psychiatrists

The COVID-19 pandemic and its impact on mental health has remained immense and global in all senses. Various types of induced psychiatric disorders, both new episodes and exacerbation of the preexisiting ones has been reported - starting from adjustment disorder to full psychotic illnesses. Various clinical symptoms, including systematized delusions, affective symptoms and self harm ideas has been mentioned needing upto prolonged admission and in patient care. Various etiopathogenetic models, incluing direct neural infection to cytokine storms or unmasking of the hidden vulnerabilities has been proposed however this needs further research. Traditional antipsychotic pharmacological agents has been proven to work well though special attention to pharmacological interactions is needed with caution for co morbid conditions and chance of side effects. We collaborated in worldwide Task Force of early career psychiatrists and prepared the definition of our point of view. © Eco-Vector, 2021.

Suicidal behavior sociocultural factors in developing countries during COVID-19.

OBJECTIVES: Sociocultural factors in the aftermath of any pandemic can play a role in increasing suicidal behavior like suicidal ideation, suicidal attempts, or suicide. The authors discuss the risk and predisposing factors for suicidal ideation among mental health patients in four developing countries (Bangladesh, Colombia, India and Pakistan), this aims to grasp the heterogeneity of these motivators and to elaborate specific interventions regarding suicide in the COVID-19 pandemic. METHODS: We searched PubMed, Medline, and Google Scholar through March, 2021 for articles using a combination of the keywords and generic terms for suicide, suicide ideation, COVID-19, developing countries, low-middle-income countries, Sociocultural factors, Suicidal behavior, predisposing factors and predictive factors, for articles in English language only, and without publication time restriction. RESULTS: This narrative review summarizes the sociocultural risk and predisposing factors for suicidal behavior in developing countries during the COVID-19 pandemic. The findings reveal those factors such as fear of being infected, growing economic pressure, lack of resources due to lockdown are mostly responsible in the four countries for the current increase in suicides. There are a few cultural differences that are specified in the narrative. CONCLUSION: The COVID-19 pandemic is a public health challenge, in which prevention and intervention of suicidal behavior have been suboptimal, especially in low-middle-income countries. Based on literature results, we provide practical suggestions (e.g., reducing infodemic, specialized helplines, improving mental health services availability) in order to tackle main challenges of suicide prevention, such as lack of adequate manpower, fragile health system and poverty.

Sialoglycan recognition is a common connection linking acidosis, zinc, and HMGB1 in sepsis.

Blood pH is tightly maintained between 7.35 and 7.45, and acidosis (pH <7.3) indicates poor prognosis in sepsis, wherein lactic acid from anoxic tissues overwhelms the buffering capacity of blood. Poor sepsis prognosis is also associated with low zinc levels and the release of High mobility group box 1 (HMGB1) from activated and/or necrotic cells. HMGB1 added to whole blood at physiological pH did not bind leukocyte receptors, but lowering pH with lactic acid to mimic sepsis conditions allowed binding, implying the presence of natural inhibitor(s) preventing binding at normal pH. Testing micromolar concentrations of divalent cations showed that zinc supported the robust binding of sialylated glycoproteins with HMGB1. Further characterizing HMGB1 as a sialic acid-binding lectin, we found that optimal binding takes place at normal blood pH and is markedly reduced when pH is adjusted with lactic acid to levels found in sepsis. Glycan array studies confirmed the binding of HMGB1 to sialylated glycan sequences typically found on plasma glycoproteins, with binding again being dependent on zinc and normal blood pH. Thus, HMGB1-mediated hyperactivation of innate immunity in sepsis requires acidosis, and micromolar zinc concentrations are protective. We suggest that the potent inflammatory effects of HMGB1 are kept in check via sequestration by plasma sialoglycoproteins at physiological pH and triggered when pH and zinc levels fall in late stages of sepsis. Current clinical trials independently studying zinc supplementation, HMGB1 inhibition, or pH normalization may be more successful if these approaches are combined and perhaps supplemented by infusions of heavily sialylated molecules.
