[Hypertension and brain function. Correlation of high blood pressure and demencia in aging. Hypertension in young-middle adults - demencia in elderly]

SZÉKÁCS Béla, KÉKES Ede

[The cerebral vascular damage caused by hypertension is manifested primarily in cognitive dysfunction, which is caused by hypoperfusion of brain tissue, ischemic, or bleeding stroke, or white matte injury. Hypertension may not only result in cerebral damage to the vascular background - dementia -, but may also contribute to the development and progression of classical gene-related Alzheimer’s disease. Blood pressure gradually increases in the elderly and in the very elderly, and the frequency of hypertension-mostly as isolated systolic hypertension - is 50% to 70%. High blood pressure predominately, or in full, means not only an increase in the circulatory resistance of the small children, but also, as part of the aging of the body, the rigidity (stiffness) of the arteries. At the same time, the incidence of dementia, along with age, rises sharply - up to 20% in those over 65 years of age, and over 40% in 80-90 years of age. The relationship between high blood pressure and dementia from the young age to the very old age may change as a function of current age. In the very old age of life, the varying influence of other pathological factors other than hypertension is becoming more and more important in the deterioration of both the vascular structure and the brain function. In this late stage of life, the very advanced rate of aging and nutritive blood flow often require higher perfusion pressure, and the not enough thought-out blood pressure reduction can be more damaging than a protective effect on brain condition or function. SPRINT MIND - the Intense Blood Pressure Reduction - hasn’t resolved the question, and we can legally assume that the 130-140 Hgmm SBP. Is the most favorable for dementia. The value of DBP 70 Hgmm is definitely unfavorable.]

[Predictive factors for ischemic heart disease, diabetes mellitus and chronic kidney disease among hypertensive patients based on the data of the Hungarian Hypertension Registry 2011-2013-2015. Part I. Hypertensive population aged 35 to 64 years]

[The association of hypertension with ischemic heart disease, diabetes and chronic kidney disease is the greatest therapeutic challenge because these associations significantly increase mortality and deteriorate life expectancy. It is important for the clinician to clarify the predictive factors of each association for successful prevention or slowing the progression of diseases. According to the database of the Hungarian Hypertension Registry 2011-2013-2015, 11,137 men and 11,112 women with hypertension and comorbidities (CHD, diabetes, CKD) aged between 35 and 64 were analyzed for the purpose of assessing the predictive value of the traditional risk factors in co-morbidity. We analyzed the predictive weight of each variable with single- and multi-variable stepwise logistic regression, and reported Odds ratio (OR, odds ratio). In patients with hypertension aged 35-64 (male / female), the prevalence of CHD was 41.6% / 35.8%, diabetes 27.1% / 23% and KVB 16.2% / 33.8%, respectively. The chance of developing CHD is highest in hypertensive individuals (male/female) who have diabetes (OR 1.30/1.48), who are obese (OR 1.22/1.21), who smoke (OR 1.50/1.51), and whose blood pressure >140/90 mmHg (OR 1.23/1.29). The dominant predictive factors of type 2 diabetes are obesity (visceral obesity) (OR 1.46/1.49), low HDL cholesterol (OR 1.32/1.35), and high triglyceride levels (OR 1.20/1.42); in women the uric acid level also showed high odds ratio (OR 1.39). There is a significant chance of developing chronic kidney disease in hypertension in both sexes, if abnormal uric acid levels (OR 1.73/1.46) and inadequate treatment of high blood pressure (>140Hgmm SBP) (OR 1.43/1.19) are present. In women, the abnormal triglyceride level) also showed a high odd (OR 1.81).]

[Serotoninergic drugs for weight loss. A review of efficacy and cardiovascular safety of lorcaserin]

SIMONYI Gábor

[Complex therapy of obesity consist the medical treatment. Several weight lowering drugs are available in the United States, one of which is 5-HT2c agonist lorcaserin. After failures with former non-selective serotoninergic agents (fenfluramine, dexfenfluramine), there was great anticipation and more questions about the release of lorcaserin, which proved its effectiveness and safety in several phase 3 studies. Lorcaserin is a selective agonist of 5-HT2c receptors, therefore free form adverse effects of former non-selective serotoninergic drugs on valvulopathy or pulmonary hypertension. The results of the recently published CAMELLIATIMI 61 study confirmed the cardiovascular safety of lorcaserin.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]
