Mental health related stigma in Romania: systematic review and narrative synthesis.

BACKGROUND: Stigma related to mental illness is increasingly and more effectively addressed. Although more research is being conducted, there is relatively little from low and middle-income countries, with former Soviet bloc countries identified as a particular contributor to this evidence gap. Romania struggles with mental health stigma at many levels. The aim of this review was to bring together all relevant data regarding stigma and discrimination related to mental illness as well as actions to address these problems in Romania in order to prioritise further stigma research and identify priority targets for stigma reduction. METHODS: A systematic literature search was conducted in three online databases and grey literature. After the analysis of full manuscripts, four were excluded based on lack of relevance or incomplete data reporting. Quality assessment was performed for included studies using the Mixed Methods Appraisal Tool (MMAT) and the narrative was synthesized based on the research questions. RESULTS: The review included fifteen studies, the majority having a cross-sectional design. Stigma related to mental illness in Romania, has an impact on help-seeking attitudes and behaviours, workplace environment and social relationships of people with mental health problems. Negative stereotypes are maintained and validated by mass media reports. Significant stigma in healthcare and mental care settings has also been observed. Self-stigma was less frequently reported than public stigma. Despite a few stigma reduction actions, no rigorous evaluation of content, delivery and effectiveness has been conducted and no empirical evidence has been published. CONCLUSIONS: Based on this review, three lines of action are recommended in Romania. Increase research concerning stigma in healthcare and mental care settings and use behavioural outcomes. Develop and deliver evidence-based tailored interventions to reduce stigma in identified priority subgroups of the population and ensure rigorous evaluation and scientific dissemination. Elaborate guidelines for working with community stigma and advocate for structural changes.

MOKE setup exploiting a nematic liquid crystal modulator.

Here we report on the magneto-optical Kerr effect employing a nematic liquid crystal (LC) device as an optical modulator. This device allows performing intensity, phase, and polarization modulated measurements with a huge signal-to-noise ratio when compared to those obtained by means of an opto-mechanical chopper and a photo-elastic modulator. The results demonstrate that the optimal performance is achieved modulating the polarization state of the incident light by means of the LCs.

Quantifying the critical thickness of electron hybridization in spintronics materials.

In the rapidly growing field of spintronics, simultaneous control of electronic and magnetic properties is essential, and the perspective of building novel phases is directly linked to the control of tuning parameters, for example, thickness and doping. Looking at the relevant effects in interface-driven spintronics, the reduced symmetry at a surface and interface corresponds to a severe modification of the overlap of electron orbitals, that is, to a change of electron hybridization. Here we report a chemically and magnetically sensitive depth-dependent analysis of two paradigmatic systems, namely La1-xSrxMnO3 and (Ga,Mn)As. Supported by cluster calculations, we find a crossover between surface and bulk in the electron hybridization/correlation and we identify a spectroscopic fingerprint of bulk metallic character and ferromagnetism versus depth. The critical thickness and the gradient of hybridization are measured, setting an intrinsic limit of 3 and 10 unit cells from the surface, respectively, for (Ga,Mn)As and La1-xSrxMnO3, for fully restoring bulk properties.

Design and optimization of a modular setup for measurements of three-dimensional spin polarization with ultrafast pulsed sources.

ULTRASPIN is an apparatus devoted to the measurement of the spin polarization (SP) of electrons ejected from solid surfaces in a UHV environment. It is designed to exploit ultrafast light sources (free electron laser or laser high harmonic generation) and to perform (photo)electron spin analysis by an arrangement of Mott scattering polarimeters that measure the full SP vector. The system consists of two interconnected UHV vessels: one for surface science sample cleaning treatments, e-beam deposition of ultrathin films, and low energy electron diffraction/AES characterization. The sample environment in the polarimeter allows for cryogenic cooling and in-operando application of electric and magnetic fields. The photoelectrons are collected by an electrostatic accelerator and transport lens that form a periaxial beam that is subsequently directed by a Y-shaped electrostatic deflector to either one of the two orthogonal Mott polarimeters. The apparatus has been designed to operate in the extreme conditions of ultraintense single-X-ray pulses as originated by free electron lasers (up to 1 kHz), but it allows also for the single electron counting mode suitable when using statistical sources such as synchrotron radiation, cw-laser, or e-gun beams (up to 150 kcps).

Lorentz microscopy sheds light on the role of dipolar interactions in magnetic hyperthermia.

Monodispersed Fe3O4 nanoparticles with comparable size distributions have been synthesized by two different synthesis routes, co-precipitation and thermal decomposition. Thanks to the different steric stabilizations, the described samples can be considered as a model system to investigate the effects of magnetic dipolar interactions on the aggregation states of the nanoparticles. Moreover, the presence of magnetic dipolar interactions can strongly affect the nanoparticle efficiency as a hyperthermic mediator. In this paper, we present a novel way to visualize and map the magnetic dipolar interactions in different kinds of nanoparticle aggregates by the use of Lorentz microscopy, an easy and reliable in-line electron holographic technique. By exploiting Lorentz microscopy, which is complementary to the magnetic measurements, it is possible to correlate the interaction degrees of magnetic nanoparticles with their magnetic behaviors. In particular, we demonstrate that Lorentz microscopy is successful in visualizing the magnetic configurations stabilized by dipolar interactions, thus paving the way to the comprehension of the power loss mechanisms for different nanoparticle aggregates.
