Introduction Almost all societies of the world are ageing. One of the most common problems of the elderly are falls and mobility disorders. They may result in disability and in loss of functional independence. We conducted the study to assess the relationship between the level of physical activity and the risk of falls and depression in adults aged 60-75 years. Materials and Methods We used the random route method and included 500 subjects from southeast Poland. We measured physical activity with the International Physical Activity Questionnaire (IPAQ), and we assessed the risk of falls with the Tinetti test. To assess depressive states, we used the Geriatric Depression Scale (GDS-15). We used a questionnaire to obtain sociodemographic and anthropometric data. Results The mean weekly energy expense (metabolic equivalent of task - MET) of the studied population measured with the IPAQ was 823.88 MET min/week. We found a statistically significant relationship between the level of physical activity and the risk of falls and depression in the studied population. Subjects with insufficient physical activity had statistically higher risk of falls (p=0.0373), and had depression statistically more often (p=0.0003). Conclusion Subsequent studies should aim at establishing an optimal training programme for the elderly. It is important for subjects over 60 years of age to know that physical activity is crucial for maintaining good health and functional ability, as well as for subjective wellbeing.

Genetic factors may play a role in the etiology of depressive disorder. The type 2 iodothyronine deiodinase gene (DIO2) encoding the enzyme catalyzing the conversion of T4 to T3 is suggested to play a role in the recurrent depressive disorder (rDD). The current study investigates whether a specific single nucleotide polymorphism (SNP) of the DIO2 gene, Thr92Ala (T/C); rs 225014 or ORFa-Gly3Asp (C/T); rs 12885300, correlate with the risk for recurrent depression. Genotypes for these two single nucleotide polymorphisms (SNPs) were determined in 179 patients meeting the ICD-10 criteria for rDD group and in 152 healthy individuals (control group) using a polymerase chain reaction (PCR) based method. The specific variant of the DIO2 gene, namely the CC genotype of the Thr92Ala polymorphism, was more frequently found in healthy subjects than in patients with depression, what suggests that it could potentially serve as a marker of a lower risk for recurrent depressive disorder. The distribution of four haplotypes was also significantly different between the two study groups with the TC (Thr-Gly) haplotype more frequently detected in patients with depression. In conclusion, data generated from this study suggest for the first time that DIO2 gene may play a role in the etiology of the disease, and thus should be further investigated.

It is a well known, that the physical activity promotes mental health. Physically active people relatively rarely suffer from psychosomatic and depressive disorders. It is possible that the differences in gene activity in peripheral blood leukocytes may be associated with depression, especially genes participating in inflammatory response. Thus, the aim of our study was to investigate the levels of IL6 and IL10 mRNA and IL10/IL6 ratio in peripheral blood leukocytes in healthy, physically active individuals. One hundred healthy young men (20-23 years old) participated in this study. All of them declared regular physical activity. Participants were non-smokers, and consumed alcohol occasionally. To access genes expression, 2 ml of venous blood was collected. RNA isolation was performed and then the relative expression of IL6 and IL10 was calculated using quantitative real-time polymerase chain reaction (Q-RT-PCR). Pro and anti-inflammatory balance was calculated as 2^relative of IL10/ 2^relative expression of IL6. Low expression of tested genes was found in healthy young men. Mean expression for IL6 was 2^0.051 (n=90) and for IL10 2^0.08 (n=98). Mean ratio IL10/IL6 was 2^1.58. Higher expression of IL10 compared to IL6 may be essential not only for the physical performance but also for the mental health. Diverse reports in the literature may be associated with choosing various control groups, i.e. sedentary or older individuals. It is possible, that measuring the expression of IL6 and IL10 (especially the ratio IL10/IL6) in peripheral blood leukocytes may be useful in the assessment of depressive disorders. Thus, molecular study of active young men can confirm the need for physical activity among people suffering from depression, but further studies are needed, particularly among people with psychosomatic disorders.

Neuroinflammation is a known factor in the pathogenesis of recurrent depressive disorders. Depression is accompanied by activated immune-inflammatory pathways including increased levels of TNFα, sTNFR1and sTNFR2.The purpose of this study was to analyse the TNF-α, TNFRSF1A and TNFRSF1B genes on both mRNA and protein levels in patients with rDD, and to investigate the relationship between TNF-α,TNFRSF1A and TNFRSF1B gene expression and cognitive performance. The study comprised 158 subjects: patients with recurrent depressive disorder (n=89) and healthy subjects (n=69). Cognitive function assessment was based on: Trail Making Test, The Stroop Test, Verbal Fluency Test and Auditory Verbal Learning Test. Both mRNA and protein expression levels of all genes were significantly higher in rDD subjects when compared to healthy controls. No statistically significant correlations were observed between the analysed variables in both the rDD group and the HS test group. The only exception was noticed in the HS test group, where increased expression of TNFRSF1A and TNFRSF1B gene negatively affected the performance of the AVLT test. However, statistically significant correlations between TNF, TNFRSF1A, TNFRSF1B mRNA gene expression levels and all the neuropsychological tests used in the survey for the entire group were observed. Conclusions: 1.The results of our study show increased expression of the TNF, TNFRSF1A and TNFRSF1B genes on both mRNA and protein levels in depression. 2. Elevated expression of TNF-α, TNFRSF1A and TNFRSF1B negatively correlates with cognitive efficiency: working memory, executive functions, attention, auditory-verbal memory, effectiveness of learning processes and verbal fluency.

Multiple sclerosis is chronic and progressive disorder of central nervous system, in which different psychiatric diagnosis comorbit in 75% with neurological symptoms. The reasons of depressive disorders are still not precisely known. Psychiatric disorders are often comorbid with neurological disorders and also influence diagnosis and treatment, more often than in other somatic illnesses. It is worth to emphasize that psychic disturbances are a consequence of neurological disorders but can also be primary sign of the disease. Especially emotional disorders and cognitive impairment are characteristic to patients with multiple sclerosis. Emotional, behavioural disorders and cognition dysfunction are often a result of pharmacotherapy of neurological disorders. Psychiatric disorders are often met in patients with autoimmunological disorders, what is more corticosteroid treatment may worsen the symptoms. Depressive disorders, especially serious and moderate episodes, occur twice more frequent than in general population. Following some authors patients suffering from multiple sclerosis and psychiatric disorders present deeper cognitive function impairment, poorer life quality and motor abilities as well as have worse treatment response. Although cognitive functions’ worsening occurs in half number of multiple sclerosis patients, dementia appears in few cases. Psychiatric disorders commonly comorbit with multiple sclerosis have adverse influence on everyday functioning.

Stwardnienie rozsiane jest przewlekle postępującym schorzeniem ośrodkowego układu nerwowego, w którym dolegliwościom i objawom neurologicznym u około 75% pacjentów towarzyszą różne zaburzenia psychiczne. Do chwili obecnej nie ustalono jednoznacznie przyczyn depresji u chorych na stwardnienie rozsiane. Ponieważ zaburzenia psychiczne współistnieją w schorzeniach neurologicznych o wiele częściej niż w innych chorobach somatycznych, dosyć często wywierają wpływ na rozpoznanie i leczenie. Należy także pamiętać, że niektóre zaburzenia psychiczne mogą być powikłaniem schorzeń neurologicznych lub też stanowić objaw pierwotny choroby. Dotyczy to szczególnie zaburzeń emocjonalnych i funkcji poznawczych u chorych na stwardnienie rozsiane. Objawy dotyczące zaburzeń emocjonalnych i zachowania oraz zaburzeń funkcji poznawczych mogą być następstwem prowadzonego leczenia farmakologicznego schorzeń neurologicznych. Objawy psychiczne często występują u chorych na schorzenia autoimmunologiczne, dodatkowo stosowane u tych pacjentów leczenie kortykosteroidami może zaostrzać te objawy. Zaburzenia depresyjne, w tym epizody ciężkie i umiarkowane depresji, występują u chorych na stwardnienie rozsiane dwukrotnie częściej niż w populacji ogólnej. W ocenie niektórych autorów pacjenci ze stwardnieniem rozsianym i współwystępującymi zaburzeniami depresyjnymi wykazują głębsze upośledzenie funkcji poznawczych, prezentują gorszą jakość życia, mają większy stopień niepełnosprawności pod względem ruchowym oraz gorzej reagują na leczenie. Jakkolwiek zaburzenia funkcji poznawczych pojawiają się u połowy pacjentów chorujących na stwardnienie rozsiane, to jednak proces otępienny występuje u nielicznych osób z tym schorzeniem. Występujące dosyć powszechnie w przebiegu stwardnienia rozsianego objawy psychiczne wpływają niekorzystnie na codzienne funkcjonowanie tych chorych.
