The Prevalence of Depression in Dementia Syndrome.

BACKGROUND: It is estimated that up to 90% of patients with dementia are affected by behavioral and psychiatric symptoms during the course of the disease. The aim of this study was to investigate the prevalence of depression in dementia and mild cognitive impairment (MCI), the use of benzodiazepines and antidepressants among them and the impact of former education on their cognitive decline. SUBJECTS AND METHODS: In the study we have enrolled 100 patients with clinical diagnoses of either MCI or dementia, as was established by a single cognitive neurology subspecialist. All patients were assessed during their regular outpatient follow-ups in the University Clinical Center Zagreb, Croatia, in the period between November 2019 and March 2020. Using the patients' medical history the demographic data, disease characteristics, history of other diseases, use of medications, Mini-Mental State Examination (MMSE) and the data on radiological brain examinations were obtained. The statistical tests were used depending on the distribution of variables. RESULTS: In total, there were 34 patients diagnosed with dementia and 66 diagnosed with MCI. The diagnosis of depression before the onset of dementia or MCI was established in 11% and it has developed in further 20% after cognitive deterioration, which represents an increase of 81.81%. The total prevalence of depression in the study group is thus 31%.The proportion of patients taking benzodiazepines was 26% and antidepressants 17%.The MMSE scores were significantly lower in patients with Alzheimer's disease than in patients with vascular MCI or dementia. Generally, MMSE values correlated significantly with the duration of education. CONCLUSIONS: Depression is a frequent accompanying disease of dementia that aggravates already complex clinical picture and greatly diminishes the quality of life of the patient. It is important to monitor changes in a patient's cognitive decline and presence of psychiatric symptoms in order to give medical professionals a better chance to alleviate the complex issues that arise during the management of this specter of diseases.

Weather patterns and occurrence of epileptic seizures.

BACKGROUND: The results of various studies that have so far evaluated the influence of meteorological conditions on seizures are often divergent. No studies have been performed so far that evaluate the possible correlation between the occurrence of seizure-related events, surface and upper level atmospheric conditions and biometeorological forecasts. The aim of this study is to investigate those interactions. METHODS: Records of "Sveti Duh" University hospital, Zagreb, Croatia between January 2016 and May 2020 were analysed in order to determine number of patients per day who were assessed through Emergency room because of a recent epileptic seizure. The dates were assessed for surface and upper level atmospheric conditions and biometeorological forecasts. Analyses of these factors were performed for two consecutive days preceding that day, the day of seizure, as well as for the following day. Data was analysed using chi-squared test, Mann-Whitney U-test or Kruskal-Wallis test (with Conover's test for post-hoc analyses), depending on variable type. Additionaly, logistic regression was used to study effects of variables on seizure occurrence. Statistical significance was set to p < 0.05. RESULTS: Results showed significant difference between the numbers of patients with seizure depending on upper level type on the following day. We also observed fewer daily patients with seizures when the synoptic situation on the following day was high pressure field then when it was low pressure or non-gradient pressure field (observed just during the colder part of the year), which was supported in our regression analyses. A greater frequency of seizures was observed if the biometerological prognosis was deemed unfavourable on the following day. Furthermore, our results showed significantly larger proportion of days with seizure patients in warmer, than in colder days of the year. CONCLUSIONS: All of the analyzed weather-related parameters seem to be associated with daily numbers of seizures on the previous day. The reason behind this phenomenon is uncertain; however, the results indicate that weather patterns have a certain influence on patients with epilepsy, but are not yet fully understood or adequately appreciated.

HYBRID MICROSURGICAL AND ENDOVASCULAR APPROACH IN THE TREATMENT OF MULTIPLE CEREBRAL ANEURYSMS: AN ILLUSTRATIVE CASE SERIES IN CORRELATION WITH LITERATURE DATA.

Contemporary cerebral aneurysm treatment has advanced due to the expansion of microsurgical and endovascular techniques having different advantages and restraints. However, some aneurysms cannot be effectively treated by a single method alone due to their specific anatomy, location, complexity, and/or multiplicity. Subsequently, multiple aneurysms sometimes necessitate a hybrid strategy integrating both methods. The study aims were to discuss indications, possibilities, and challenges of a hybrid strategy in the decision making and treatment of multiple intracranial aneurysms. A single-institution illustrative case series of multiple intracranial aneurysm patients treated by a hybrid approach was analyzed and management outcome discussed and correlated with literature data. Following the treatment, both patients from our case series recovered well, having complete and stable aneurysmal occlusion with no relapse and no postoperative procedure-related complications or long-lasting neurological symptoms. In conclusion, a hybrid approach is advised as a treatment option for multiple cerebral aneurysms when a single modality is insufficient to bring satisfactory results. It may be a suitable and safe addition to an assortment of treatments pledging clinical improvement and enabling positive management outcome in patients with ruptured and non-ruptured multiple cerebral aneurysms.

Epidemiology of Pharmacological Treatment of Multiple Sclerosis in Croatia.

Treatment of multiple sclerosis has been a dynamic field lately, with many new and emerging treatment options. In this study, we investigate the use of disease modifying therapies (DMTs) for multiple sclerosis in Croatia. The data on DMT use was provided by the Agency for Medicinal Products and Medical Devices of Croatia (HALMED). The data from 2005 to 2016 was available. Consumption of DMTs (in DDD/1000/day) has been increasing by 9% annually on average since 2005. In the same period, the annual cost for those drugs has been increasing by 14.6% annually on average. The consumption of IFN-beta 1-a has been increasing by a much steeper rate than IFN-beta 1-b. Until 2010 the consumption of glatiramer acetate has been negligible, with a steep increase between 2011 and 2014, and a steady rate of consumption since. Recently, several new DMTs became available, namely dimethyl fumarate, teriflunomide and fingolimod. Natalizumab became available after 2010, and its consumption has been growing steadily, but its consumption figures are exceeded by alemtuzumab. New DMTs are not as readily available in Croatia as they are in some countries. However, there is a continuous increase in the number of prescriptions, along with growing costs in pharmacological treatment of multiple sclerosis, and this can be expected to become even more pronounced in the following years, due to the abundance of new therapeutic options that are steadily becoming available.

Elevated Concentrations of Soluble Fas and FasL in Multiple Sclerosis Patients with Antinuclear Antibodies.

Antinuclear antibodies (ANA) are currently considered as an epiphenomenon of apoptotic processes, possibly in control of autoreactivity in patients with multiple sclerosis (MS). Apoptosis of reactive lymphocytes by the Fas/FasL system is described as an effective control mechanism for autoreactivity in MS. We aimed to provide a context to the potential link between ANA and peripheral lymphocyte apoptosis in MS. The presence of ANA was detected in sera by immunofluorescence assay, and concentrations of sFas and sFasL were determined in the sera of 44 and cerebrospinal fluid (CSF) of 11 relapsing-remitting (RR) MS patients using cytometric bead-based array, and their association with the disease characteristics was determined. ANA were detected in the sera of 43.2% of RRMS patients, and their frequency was the highest in patients with disease duration of less than one year (88,89%). In addition, the number of experienced relapses was lower in ANA-positive patients. Concentrations of sFasL were inversely associated with patients' expanded disability status scale (EDSS) scores. Low concentrations of both soluble factors strongly discriminated patients with moderate to severe disability, from patients with mild or absent disability only in a group of patients with prolonged disease duration (>10 years). Both soluble mediators were significantly higher in ANA-positive patients. FasL concentrations were inversely associated with the number of relapses. There is a potential link between the presence of ANA and peripheral lymphocyte apoptosis mediated by Fas/FasL system in MS, whose precise role and significance needs to be determined by future mechanistic studies.

Online epilepsy counseling in Croatia: What do users want to know?

PURPOSE: The purpose of this study is to better understand which specific epilepsy-related issues are cause for seeking out professional advice online. METHOD: An online epilepsy counseling service introduced by the Croatian Epilepsy Association allows users to anonymously submit questions related to epilepsy via e-mail or online contact form, which are later answered by an epilepsy professional. The questions were classified both by inquirers and by content. Inquirers were classified as patients, patient's parents, family members, partners, and friends of patients with epilepsy. In terms of content, questions were divided into three groups: medical, socially-oriented, and unclassifiable questions. RESULTS: In sum, 355 e-mails, which included 513 questions, were analyzed. The vast majority of inquirers were patients themselves (48%) and parents of patients (28%). While 76% of questions concerned the medical aspects of epilepsy, there was as well significant interest in administrative and practical issues associated with the diagnosis of epilepsy. Among medical questions, the most popular concerned prognosis (15%) and second opinions (14%); among socially-oriented questions, inquirers were primarily interested in matters associated with their profession (28%). As well, the parents of patients were more likely to question an epilepsy diagnosis than the patients themselves (p<0.001). CONCLUSION: According to the results of this study, it is clear that epilepsy professionals should invest more time in discussing with patients the topics which interest them the most, as well as refer them to other professionals that can help them with non-medical epilepsy-related issues, and advise them on reliable Internet sources.

Epidemiological Characteristics of Dementia Treatment in Croatia.

BACKGROUND: In spite of the increase in the number of patients with dementia in countries with older population, basic epidemiologic data are still scarce. The objective of this paper is to investigate pharmacoepidemiological characteristics of treatment of dementia in Croatia, and to present them in the context of certain epidemiological characteristics that illustrate the growing pressure this disease exerts on the healthcare system. SUBJECTS AND METHODS: Data on medication utilization were taken from Croatian Health Insurance Fund (HZZO) and Agency for Medicinal Products and Medical Devices of Croatia (HALMED). Data on the number of hospital stays were supplied by Croatian Institute of Public Health (HZJZ). Internal data on the number of outpatient examinations from the Clinical hospital "Sveti Duh" were used as well. RESULTS: In the observed period (2012-2014), 4568 patients were treated with anti-dementia medications, of which 1275 (32%) with donepezil, and 2753 (68%) with memantine. According to HALMED, the utilization of those medications is constantly increasing, and has increased manifold from 2005 to 2014. The estimate of the proportion of treated patients with dementia aged 60 years and over is around 9.2%. The number of dementia-related hospital stays is also increasing, and has increased by 9.6% in the last 5-year period, compared to the preceding 5-year period. The number of outpatient examinations in Clinical Hospital "Sveti Duh" grew from 351 in 2007 to 1151 in 2015 (January 1(st) - October 26(th)). CONCLUSION: The strain this condition exerts on the healthcare system is increasing yearly. In spite of the large increase in the medication utilization over the previous years, the proportion of treated patients is still small, and further increase in their use is to be expected. It is necessary to monitor this in the years ahead.

How does the label "epileptic" influence attitudes toward epilepsy?

PURPOSE: The purpose of our research was to study the possible differences in attitudes toward epilepsy based on the label used: "person"/"child with epilepsy" vs. "epileptic"/"epileptic child". METHODS: Two randomly assigned groups of college-preparatory high school students were questioned using anonymous questionnaires about their demographics, knowledge on epilepsy and attitudes toward epilepsy. Attitudes were measured using three general attitude questions and a six item modified version of the Bogardus social distance scale. Two versions of the questionnaire were identical except for the term "person"/"child with epilepsy" in first group (group A) being replaced with the term "epileptic"/"epileptic child" in the second one (group B). Mann-Whitney test was used to compare attitude scores between groups. RESULTS: There were 425 subjects in total, 208 in group A and 217 in group B. The results on the Social distance scale indicated significantly more negative attitudes in group B (p=0.008). Subjects in group B also expressed more negative attitudes than those in group A when asked about sharing a room with a person with epilepsy (p=0.005) and marrying a person with epilepsy, either themselves (p=0.033) or when the person getting married is someone close to them (p=0.024). CONCLUSION: In conclusion, using term "epileptic" can evoke more negative attitudes toward a person with epilepsy and this seems to be especially true for more intimate life domains (cohabitation or marriage), while in more impersonal domains (such as communicating and working with a person with epilepsy), no significant influence of the label on attitudes was proven.

Neurologic parameters in the perinatal period in children with neurodevelopmental disorders.

UNLABELLED: Cerebral palsy (CP) is a term encompassing a group of nonprogressive, noncontagious conditions causing mild, moderate or severe disorders of neurodevelopment. OBJECTIVE: Objective of this study was to analyze the possible prenatal etiological factors for the emergence of neurodevelopmental disorders (NDs) and CP from the medical records of 100 children with neuromotor disabilities who were treated in Special Hospital for Children with Neuro-developmental and Movement Disorders, Goljak, Croatia. RESULTS: ND and CP were more often diagnosed in children with birth weight below 2500 g which was statistically proved at the level of significance reaching 0.05, although significant correlation was low for both parameters reaching 0.21. There are both statistically significant differences and the statistically significant correlation between the three gestational age categories within ND and CP. There were more children with the birth weight below 2500 g in the CP than in the ND group and the difference was statistically significant. In the CP group, there were more children with the lower gestational age than in the ND group, which was statistically highly significant. This difference, together with correlation is significant at the level of 0.01. CONCLUSION: Further studies on the etiology of NDs are needed, with particular focus on the intrauterine risk factors.

Neurobehavioral continuity from fetus to neonate.

Neurobehavior represents development of the central nervous system (CNS). Fetuses and newborns exhibit a large number of endogenously generated motor patterns, among which general movements are often investigated pre- and post-natally. Spontaneous activity is probably a more sensitive indicator of brain dysfunction than reactivity to sensory stimuli while testing reflexes. Nutritional stress at critical times during fetal development can have persistent and potentially irreversible effects particularly on brain growth and function. Unfavorable intrauterine environment can affect adversely brain growth. All endogenously generated movement patterns from un-stimulated CNS might be observed as early as from the seven to eight weeks' gestation, with a rich repertoire of movements within the next two or three weeks, continuing for five to six months postnatally. It is still uncertain whether a new scoring system for prenatal neurological assessment will be adequate for the distinction between normal and abnormal fetuses in low-risk pregnancies. The continuity of behavioral patterns from prenatal to postnatal life might answer these intriguing questions.

4D Ultrasound - Medical Devices for Recent Advances on the Etiology of Cerebral Palsy.

Children cerebral palsy (CCP) encompasses a group of nonprogessive and noninfectious conditions, which cause light, moderate, and severe deviations in neurological development. Diagnosis of CCP is set mostly by the age of 3 years. The fact that a large number of cerebral damage occurs prenatally and the fact that early intervention in cases of neurological damage is successful, prompted some researchers to explore the possibility of detecting neurologically damaged fetus in the uterus. This research was made possible thanks to the development of two-dimensional ultrasound technology in a real time, which enabled the display of the mobility of the fetus. Advancement of the ultrasound technology has enabled the development of 4D ultrasound where a spontaneous fetal movement can be observed almost in a real time. Estimate of the number and quality of spontaneous fetal movements and stitches on the head, the neurology thumb and a high palate were included in the prenatal neurological screening of the fetus. This raises the question, as to does the fetal behavior reflect, (which was revealed in 2D or 4D ultrasound), fetal neurological development in a manner that will allow the detection of the brain damage.

Gastric pentadecapeptide BPC 157 as an effective therapy for muscle crush injury in the rat.

PURPOSE: Stable gastric pentadecapeptide BPC 157 accelerates the healing of a transected Achilles tendon and a transected quadriceps muscle. It may also be of clinical relevance as a systemic and local peptide treatment for crush injury of a major muscle, such as gastrocnemius muscle complex. BPC 157 is effective without a carrier, and it is presently undergoing trials for inflammatory bowel disease, and no toxicity has so far been reported. METHODS: In crushed rats (force delivered 0.727 Ns/cm2), BPC 157 was applied either intraperitoneally or locally, as a thin cream layer, immediately after injury (sacrifice at 2 h), and once a day for 14 days. RESULTS: BPC 157 improved muscle healing, macroscopically (less hematoma and edema, no post-injury leg contracture), microscopically, functionally, and also based on enzyme activity (creatine kinase, lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase). CONCLUSION: BPC 157, at all investigated intervals, given locally or intraperitoneally, accelerated post-injury muscle healing and also helped to restore the full function.
