BACKGROUND: Mild behavioral impairment (MBI) has been commonly reported in early Alzheimer's disease (AD) but rarely using biomarker-defined samples. It is also unclear whether genetic polymorphisms influence MBI in such individuals. We thus aimed to examine the association between the cognitive status of participants (amnestic mild cognitive impairment (aMCI-AD) vs cognitively normal (CN) older adults) and MBI severity. Within aMCI-AD, we further examined the association between APOE and BDNF risk genetic polymorphisms and MBI severity. METHODS: We included 62 aMCI-AD participants and 50 CN older adults from the Czech Brain Aging Study. The participants underwent neurological, comprehensive neuropsychological examination, APOE and BDNF genotyping, and magnetic resonance imaging. MBI was diagnosed with the Mild Behavioral Impairment Checklist (MBI-C), and the diagnosis was based on the MBI-C total score ≥ 7. Additionally, self-report instruments for anxiety (the Beck Anxiety Inventory) and depressive symptoms (the Geriatric Depression Scale-15) were administered. The participants were stratified based on the presence of at least one risk allele in genes for APOE (i.e., e4 carriers and non-carriers) and BDNF (i.e., Met carriers and non-carriers). We used linear regressions to examine the associations. RESULTS: MBI was present in 48.4% of the aMCI-AD individuals. Compared to the CN, aMCI-AD was associated with more affective, apathy, and impulse dyscontrol but not social inappropriateness or psychotic symptoms. Furthermore, aMCI-AD was related to more depressive but not anxiety symptoms on self-report measures. Within the aMCI-AD, there were no associations between APOE e4 and BDNF Met and MBI-C severity. However, a positive association between Met carriership and self-reported anxiety appeared. CONCLUSIONS: MBI is frequent in aMCI-AD and related to more severe affective, apathy, and impulse dyscontrol symptoms. APOE and BDNF polymorphisms were not associated with MBI severity separately; however, their combined effect warrants further investigation.

Neuropsychiatrické příznaky ve stáří jsou součástí klinické manifestace neurodegenerativních onemocnění a mohou být i jejich prvním příznakem. Popisujeme koncept mírné behaviorální poruchy označující nově vzniklé a přetrvávající neuropsychiatrické příznaky s počátkem po padesátém roce života, u kterých se předpokládá neurodegenerativní etiologie. Do češtiny poprvé uvádíme nově adaptovaný dotazník mírné behaviorální poruchy sloužící k diagnostice neuropsychiatrických příznaků u starších osob a k detekci syndromu mírné behaviorální poruchy.

Neuropsychiatric symptoms in older adults are part of the clinical manifestation of neurodegenerative diseases and may even be their first symptoms. We describe the concept of mild behavioral impairment (MBI), which refers to new-onset, persistent neuropsychiatric symptoms emerging after the age of 50 years that are assumed to have a neurodegenerative etiology. We introduce the newly adapted Czech version of the Mild behavioral impairment - checklist developed to measure neuropsychiatric symptoms in older adults and for the MBI detection.

Objectives: Mild behavioral impairment (MBI) is a syndrome describing late-onset persistent neuropsychiatric symptoms (NPS) in non-demented older adults. Few studies to date have investigated the associations of MBI with structural brain changes. Our aim was to explore structural correlates of NPS in a non-demented memory clinic sample using the Mild Behavioral Impairment Checklist (MBI-C) that has been developed to measure MBI. Methods: One hundred sixteen non-demented older adults from the Czech Brain Aging Study with subjective cognitive concerns were classified as subjective cognitive decline (n = 37) or mild cognitive impairment (n = 79). Participants underwent neurological and neuropsychological examinations and brain magnetic resonance imaging (MRI) (1.5 T). The Czech version of the MBI-C was administered to participants' informants. Five a priori selected brain regions were measured, namely, thicknesses of the orbitofrontal cortex (OFC), anterior cingulate cortex (ACC), posterior cingulate cortex (PCC), and entorhinal cortex (ERC) and volume of the hippocampus (HV), and correlated with MBI-C total and domain scores. Results: Entorhinal cortex was associated with MBI-C total score (rS = -0.368, p < 0.001) and with impulse dyscontrol score (rS = -0.284, p = 0.002). HV was associated with decreased motivation (rS = -0.248, p = 0.008) and impulse dyscontrol score (rS = -0.240, p = 0.011). Conclusion: Neuropsychiatric symptoms, particularly in the MBI impulse dyscontrol and motivation domains, are associated with medial temporal lobe atrophy in a clinical cohort of non-demented older adults. This study supports earlier involvement of temporal rather than frontal regions in NPS manifestation. Since these regions are typically affected early in the course of Alzheimer's disease (AD), the MBI-C may potentially help further identify individuals at-risk of developing AD dementia.

AIM: The aim of this cytogenetic study is to confirm the significance of chromosome 3 loss (monosomy 3) and of the gain of chromosome 8 as prognostic markers in histopathological samples of enucleated eyes with uveal melanoma in the Czech population. METHODS: This is a retrospective study of 52 enucleated eyes. Chromosome 3 and 8 status were tested by CISH, and in a few samples FISH was used. The correlation between monosomy 3 and gain of chromosome 8 and clinical features (histopathological type, size of the tumour) were evaluated. A follow up for the detection of metastases was conducted in all patients. The statistical significance of chromosomal abnormalities as a prognostic factor for the development of metastases was calculated. RESULTS: There were 52 patients, 27 men (51.9%) and 25 women (48.1%) enrolled in our study group. The mean age was 63 ± 14 years. Loss of the one copy of chromosome 3 (monosomy 3) was detected in 26 (50.0%) patients, monosomy 8 was present in 34.6% of patients with monosomy 3. After 5 years there were no metastases in 82% of patients without monosomy 3 as opposed to 40% of patients with monosomy 3. We confirmed a statistically significant association between progression free survival (PFS) and the presence of monosomy 3 (P=0.017). The association between PFS and gain of chromosome 8 was significant as well (0.010). CONCLUSIONS: Our data showed the association of progression-free survival with the presence of monosomy 3 in uveal melanomas. We provided a good prognostic value of monosomy 3 in uveal melanoma.

Cíl: Neuropsychiatrické symptomy (NPS) jsou heterogenní skupina změn v osobnosti a chování, které lze pozorovat již v časných stadiích Alzheimerovy nemoci (AN). Mírná behaviorální porucha (mild behavioral impairment; MBI) je nová diagnostická kategorie popisující trvalé změny v osobnosti a chování s počátkem v pozdější fázi života. Na podkladě těchto kritérií byl vytvořen nový Dotazník mírné poruchy chování (Mild Behavioral Impairment Checklist; MBI-C) zaměřený na detekci NPS v časných stadiích AN. Cílem studie je představit námi adaptovanou českou verzi dotazníku MBI-C a studovat přítomnost a závažnost NPS na pilotním souboru pacientů. Soubor a metodika: Originální verze MBI-C byla adaptována do češtiny a administrována blízkým osobám 188 pacientů. Pacienti podstoupili komplexní neuropsychologické, neurologické vyšetření a zobrazení mozku a dle výsledků byli rozděleni do tří skupin: kognitivně zdraví (n = 69), amnestická mírná kognitivní porucha (amnestic mild cognitive impairment; aMCI) (n = 87) a demence při AN (n = 32). Výsledky: Pacienti s aMCI vykazovali v dotazníku MBI-C signifikantně vyšší skóre ve srovnání s kognitivně zdravými a zároveň nižší skóre než pacienti s demencí. Rozdíly byly patrné zejména v doménách nálady, motivace a kontroly impulzů. Závěr: Česká verze dotazníku MBI-C detekuje přítomnost NPS ještě před rozvojem syndromu demence a je dobře využitelná v klinické praxi.

Aim: Neuropsychiatric symp toms (NPS) are a heterogeneous group of changes in personality and behavior that can be observed already in early stages of Alzheimer's disease (AD). Mild behavioral impairment (MBI) is a newly developed diagnostic category describing persistent changes in personality and behavior start ing later in life. Based on these criteria, a new measure, the Mild Behavioral Impairment Checklist (MBI-C) has been developed, aimed at detecting NPS in early stages of AD. The aim of this study is to present the newly adapted Czech version of the MBI-C and to explore the presence of NPS in a pilot group of patients. Patients and methods: The original MBI-C has been adapted to Czech and administered to close informants of 188 patients. The patients were divided accord ing to the results of a complex neuropsychological, neurological examination and brain imag ing into 3 groups: cognitively normal (N = 69), amnestic mild cognitive impairment (aMCI; N = 87) and dementia due to AD (N = 32). Results: Patients with aMCI expres sed in the MBI-C significantly more severe score compared to cognitively normal subjects and less severe compared to dementia patients. The differences were observed mainly in aff ective, motivation and impulse control domains. Conclusion: The Czech version of the MBI-C detects the presence of NPS even before the onset of dementia syndrome and is useful in clinical practice.

PURPOSE: We investigated associations between neovascular age-related macular degeneration (AMD) and rs10490924 polymorphism of ARMS2 gene (age-related maculopathy susceptibility 2), rs1061170 polymorphism of gene for complement factor H (CFH), rs2230199 polymorphism of gene for complement component C3 and rs11200638 polymorphism of gene for serine protease high-temperature requirement A1 (HTRA1) in the Czech population. METHODS: We analysed samples of DNA from 307 patients diagnosed with neovascular form of late AMD (average age: 73.7 ± 7.7 years) and 191 control subjects, recruited from patients awaiting cataract surgery (average age, 73.6 ± 8.7 years). RESULTS: HTRA1, CFH and ARMS2 genes polymorphisms were found to be related to neovascular AMD in the Czech population. All analysed polymorphisms were statistically significantly associated with neovascular AMD, with stronger associations in females than in males. In whole group, CC genotype of CFH gene polymorphism, TT genotype of ARMS2 gene polymorphism and AA genotype of HTRA1 gene polymorphism showed the greatest risk for neovascular AMD with odds ratios equal to 8.43, 10.07, 9.83, respectively (p < 0.0001). Only CG polymorphism of C3 gene showed statistically significant risk for neovascular AMD. In addition, we observed an association between waist circumference and neovascular AMD in both sexes, which further suggests the significance of excessive abdominal fat as a risk factor of AMD. We found a statistically significant association between polymorphisms in HTRA1, CFH and ARMS2 genes and neovascular AMS in the Czech population. The association was stronger in females than in males. CONCLUSION: We demonstrated a relationship between neovascular AMD and genes for HTRA1, CFH, ARMS2 and C3 in Czech population. To our knowledge, the relationship between these polymorphisms and neovascular AMD in Czech population has never been investigated before.

BACKGROUND: Central serous chorioretinopathy (CSC) is characterised by a serous detachment of the neurosensory retina in the macula. Chronic CSC tends to affect older individuals with a less favourable visual outcome. Photodynamic therapy (PDT) with verteporfin is a possible therapeutic approach in cases of CSC with no tendency for spontaneous resorption. PDT has shown good anatomic and functional results in treating chronic CSC. For the purpose of diminishing side effects, modifications of the standard protocol were used. MATERIALS AND METHODS: This is a retrospective study of 32 eyes with CSC of 32 patients treated by half-fluence PDT. The patients underwent complete ophthalmology examination. On optical coherence tomography (OCT) we measured central retinal thickness (CRT), the outer nuclear layer (ONL), presence of subfoveolar detachment of retinal pigment epithelium (PED), disturbance of external limiting membrane (ELM), morphological changes in the inner segment/outer segment (IS/OS) line and retinal pigment epithelium (RPE) atrophy. We evaluated at baseline, 3 and 12 months after PDT. RESULTS: The mean BCVA at baseline was 0.41 ± 0.23 log MAR, the mean BCVA at 3 months was 0.24 ± 0.20 and at the end of the follow-up it was 0.23 ± 0.200. We observed statistically significant improvements of visual acuity after 3 and 12 months (p < 0.001, Wilcoxon test). The mean central retinal thickness at baseline was 373 ± 87 µm, the mean CRT after 3 months was 234 ± 42 µm and after 12 months 223 ± 39 µm. A significant reduction from baseline was seen after 3 months and 12 months (p < 0.001, Wilcoxon test). Baseline ONL reached 80 ± 27 µm, after 3 months it was 78 ± 20 and after 12 months it was 74 ± 20 µm. We observed a statistically significant change in diminishing the amount of PED after PDT after 3 months and after 12 months (p = 0.021, McNemar's test). We observed that in patients with RPE ablation, there is lower chance for the restitution of the IS/OS layer (p = 0.045, Mann-Whitney test). We observed a negative association between the improvement of visual acuity after 12 months and the presence of RPE ablation (p = 0.031, Mann-Whitney test). Restitution of ELM was significantly more often in patients with shorter duration of symptoms, (p = 0.027 after 3 months, p = 0.033 after 12 months after PDT, Spearman correlation). Neither ocular nor systemic adverse effects were observed during the follow-up period. CONCLUSIONS: Half-fluence PDT treatment has shown to be a usually safe and often effective therapy in patients with chronic CSC. This study suggests that the most important predictive factor is baseline visual acuity. The important anatomical change detected using OCT is a thinning of the outer nuclear layer. Nonetheless, other studies with a larger number of patients and a longer follow-up are required.
