Multinuclear Ag clusters sandwiched by Pt complex units were synthesized and characterized by single crystal X-ray diffraction and NMR studies. The sandwich-shaped multinuclear Ag complexes showed two different types of fluxional behavior in solution: rapid slippage of Pt complex units on the Ag core and a reversible demetalation-metalation reaction by the treatment with Cl anion and Ag ion, respectively. The Ag complex obtained by demetalation reaction from the Ag complex displayed U to Z isomerization. These multinuclear Ag complexes showed strong photoluminescence whose properties depended on the existence of Pt→Ag dative bonds. The Ag complex, identified to be "chiral-at-cluster", was optically resolved by the formation of a diastereomeric salt with a chiral anion. The enantiomers show circular dichroism (CD) and circularly polarized luminescence (CPL) properties which is unprecedented for compounds based on a chiral sandwich structure. Theoretical calculations allow to understand their structural features and photophysical properties.

Introduction: Self-harm represents a complex and multifaceted public health issue of global significance, exerting profound effects on individuals and communities alike. It involves intentional self-poisoning or self-injury with or without the motivation to die. Although self-harm is highly prevalent, limited research has focused on the patterns and trends of self-harm among hospital populations in low- and middle-income countries, particularly within Africa.

Lithuania ratified the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) in 2010 and started deinstitutionalization in 2014. This reform covers segregated social care institutions where persons with mental health conditions, psychosocial, and/or intellectual disabilities live. It aims to move away from institutional care and towards community-based services.

Five alkali metal manganese(III) fluorophosphates, KMn(POF)F (I), RbMn(POF)F (II), RbMn(POF)(PO)F (III), RbMn(POF)(PO)F (IV), and CsMn(POF)F (V), were successfully synthesized using a hydrothermal method. The monofluorophosphate anion (POF) groups work as "chemical scissors" to promote low-dimensional spin structures with the aid of alkali metal cations. I and II had an = 2 uniform chain structure formed by corner-sharing -MnOF octahedra.

The diagnosis and management of complex neurological conditions such as New-Onset Refractory Status Epilepticus (NORSE) and central nervous system (CNS) infections caused by non-tuberculous mycobacteria (NTM) pose substantial difficulties in intensive care units (ICUs). This article combines a case report and a literature review that explores the diagnostic dilemmas and therapeutic strategies for these critical conditions. We report the case of an 83-year-old female with chronic granulomatous meningitis secondary to NTM, presenting a challenging diagnostic and complex management complexity typical of such a rare disease through a period time of five years.

Background: Nudging involves deliberately changing the environment or context to induce better choices. Several studies consider such methods unethical manipulation that threatens the principles of informed consent and autonomy, which are particularly vital in healthcare. Others argue that nudging respects personal freedom because it is not in conflict with the person's explicit values or choices, beneficial, and easy to resist.
