Tear fluid biomarkers in major depressive disorder: Potential of spectral methods in biomarker discovery.

J Psychiatr Res 2021 Mar 29;138:75-82. Epub 2021 Mar 29.

Spectroscopic methods represent a group of analytical methods that demonstrate high potential in providing clinically relevant diagnostic information, such as biochemical, functional or structural changes of macromolecular complexes that might occur due to pathological processes or therapeutic intervention. Although application of these methods in the field of psychiatric research is still relatively recent, the preliminary results show that they have the capacity to detect subtle neurobiological abnormalities in major depressive disorder (MDD). Methods of mass spectrometry (MALDI-TOF MS), zymography, synchronous fluorescence spectroscopy (SFS), circular dichroism (CD) spectroscopy, Fourier-transform infrared (FTIR) spectroscopy and atomic force microscopy (AFM) were used to analyze the human tear fluid of subjects with MDD. Using MALDI-TOF MS, two diagnostically significant peaks (3747 and 16 411 m/z) were identified with an AUC value of 0.89 and 0.92 in tear fluid of subjects with MDD vs controls, respectively. We also identified various forms of matrix metalloproteinase 9 in subjects with MDD using zymography and synchronous fluorescence spectra (SFS) showed a significant increase in fluorescence intensity at 280 nm. CD spectra were redshifted in tear fluid of subjects with MDD vs healthy controls. FTIR spectroscopy showed changes in the positions of peaks for amide A, I, II in tear fluid of subjects with MDD vs controls. Moreover, atomic force microscopy (AFM) showed different pattern in the crystal structures of tear fluid components in subjects with MDD. SFS, CD, FTIR spectroscopy, AFM and MALDI-TOF MS confirmed, that the human tear fluid proteome could be helpful in discriminating between the group of subjects with MDD and healthy controls. These preliminary findings suggest that spectral methods could represent a useful tool in clinical psychiatry, especially in establishing differential diagnosis, monitoring illness progression and the effect of psychiatric treatment.

What mental health experts in Slovakia are learning from COVID-19 pandemic?

Indian J Psychiatry 2020 Sep 28;62(Suppl 3):S459-S466. Epub 2020 Sep 28.

National Crisis Clinical Team, Ministry of Health Slovak Republic.

Introduction: The COVID-19 pandemic was confirmed to have spread to Slovakia on 6th March 2020. To date of paper submission, it has very favorable course. However, since the beginning healthcare workers have been working under increasing pressure, anxiety and fear.

Aim: Authors evaluated the psychosocial impact of COVID-19 pandemic on mental health experts and their clinical practice in Slovakia.

Materials And Methods: A total of 157 mental health experts (79% women) submitted their responses via online questionnaire.

Results: The most frequent occupation categories were 38.2% outpatient psychiatrists, 26.1% inpatient psychiatrists and 20.4% psychologists. The mental health experts felt maximum of stress during the peak of Slovak COVID-19 crisis, which was identified as the situation just after the declaring the state of emergency by Slovak government. The main sources of stress were statistical data, prognoses and other public presented information. Mental health experts felt mainly personal stress, then general and working stress. They identified also pathological effect of COVID-19 pandemic on the mental status of their patients, especially with anxiety and affective disorders and advantages of use of telemedicine.

Conclusion: Psychosocial support in Slovakia was newly organized in COVID-19 pandemic for medical professionals, patients and other inhabitants under high stress within a very short time. This unexpected situation has revealed to Slovakia the need for reform of the mental healthcare system.

Autism and education-Teacher policy in Europe: Policy mapping of Austria, Hungary, Slovakia and Czech Republic.

Res Dev Disabil 2020 Oct 3;105:103734. Epub 2020 Aug 3.

Department of International Health, Maastricht University Faculty of Health Medicine and Life Sciences, Maastricht, the Netherlands; Institute of Public Health, University of Cambridge, Cambridge, United Kingdom; Autism Research Centre, Department of Psychiatry, University of Cambridge, Cambridge, United Kingdom.

Background: This report maps autism and special education needs (SEN) policies, alongside teacher responsibilities in the education of children with SEN in Austria, Hungary, Czech Republic, and Slovakia.

Methods And Procedure: A policy path analysis using a scoping review as an underlying methodological framework was performed.

Outcomes And Results: The end of communism and accession to the European Union were critical for the countries under study. They passed crucial policies after international policies and adopted a three-stream approach towards providing education: (1) special schools; (2) special classes in mainstream schools; or (3) mainstream classes. Special schools remain for children that cannot participate in mainstream schools. Teachers are given high levels of responsibility.

Conclusion And Implications: Changes in international guidance greatly impacted Austria, Hungary, Slovakia and the Czech Republic. The education systems aim for inclusion, though segregation remains for children that cannot thrive in mainstream schools. Teachers are pivotal in the education of children with SEN, more so than with typical children.

The altered circadian pattern of basal insulin requirements - an early marker of autoimmune polyendocrine syndromes in type 1 diabetes mellitus.

Endocr Regul 2020 Apr;54(2):126-132

1st Department of Psychiatry, Pavol Jozef Safarik University Faculty of Medicine, Kosice, Slovak Republic.

Objectives: The purpose of the present paper is to propose and introduce novel biomarkers of autoimmune polyendocrine syndromes that are relevant to the early diagnosis and optimal medical management of the patients who already suffer from type 1 diabetes mellitus.

Methods: We hypothesize and demonstrate on a case study that various organ-specific autoimmune endocrinopathies can result in lowered basal insulin requirements, leading to unexplained hypoglycemia.

Results: It can be hypothesized that hypothyroidism in patients with type 1 diabetes mellitus may deteriorate glycemic control and can lead to an increased rate of hypoglycemia, particularly the overnight and morning hypoglycemia. Thus, the decreased requirements for particularly overnight basal insulin can be an early marker of the autoimmune polyendocrine syndrome-3 with subclinical autoimmune thyroiditis in immune-mediated type 1 diabetes mellitus. Further, it could be proposed that unexplained hypoglycemia during the late afternoon or evening could be an early marker of the autoimmune polyendocrine syndrome-2 with subclinical autoimmune Addison disease in immune-mediated type 1 diabetes mellitus. As a result, an altered circadian pattern of basal insulin requirements can occur, characterized by a decreased late afternoon basal insulin rate.

Conclusions: After exclusion of other causes, the unexplained reoccurring hypoglycemia can be a remarkable feature of autoimmune polyendocrine syndromes in immune-mediated type 1 diabetes mellitus on intensive insulin replacement therapy.
