Mitochondrial membrane protein-associated neurodegeneration (MPAN) is an ultraorphan neurogenetic disease from the group of neurodegeneration with brain iron accumulation (NBIA) disorders. Here we report cross-sectional and longitudinal data to define the phenotype, to assess disease progression and to estimate sample sizes for clinical trials. We enrolled patients with genetically confirmed MPAN from the Treat Iron-Related Childhood-Onset Neurodegeneration (TIRCON) registry and cohort study, and from additional sites. Linear mixed-effect modelling (LMEM) was used to calculate annual progression rates for the Unified Parkinson's Disease Rating Scale (UPDRS), Barry–Albright Dystonia (BAD) scale, Schwab and England Activities of Daily Living (SE-ADL) scale and the Pediatric Quality of Life Inventory (PedsQL). We investigated 85 MPAN patients cross-sectionally, with functional outcome data collected in 45. Median age at onset was 9 years and the median diagnostic delay was 5 years. The most common findings were gait disturbance (99%), pyramidal involvement (95%), dysarthria (90%), vision disturbances (82%), with all but dysarthria presenting early in the disease course. After 16 years with the disease, 50% of patients were wheelchair dependent. LMEM showed an annual progression rate of 4.5 points in total UPDRS. The total BAD scale score showed no significant progression over time. The SE-ADL scale and the patient- and parent-reported PedsQL showed a decline of 3.9%, 2.14 and 2.05 points, respectively. No patient subpopulations were identified based on longitudinal trajectories. Our cross-sectional results define the order of onset and frequency of symptoms in MPAN, which will inform the diagnostic process, help to shorten diagnostic delay and aid in counselling patients, parents and caregivers. Our longitudinal findings define the natural history of MPAN, reveal the most responsive outcomes and highlight the need for an MPAN-specific rating approach. Our sample size estimations inform the design of upcoming clinical trials. [ABSTRACT FROM AUTHOR]

Management structures, Credit institution, Corporate governance - Abstract
Managing a company that acts as a member of the management board and supervisory board is an extremely demanding and responsible task. Precisely for this reason, the legislation of each country has prescribed the conditions that must be met by persons who aspire to these tasks. The most important legal framework in the Republic of Croatia is the provisions of the Companies Act. The conditions that must be fulfilled by the members of the management, supervisory board, and board of directors of credit institutions are more demanding than the conditions prescribed for the members of the management structures of non- financial companies. These conditions are specified in the Credit Institutions Act. The aim of the paper is to analyse the management, supervisory board and general assembly of credit institutions in accordance with the Croatian legislation. The research was conducted on the basis of available scientific and other relevant literature.

The hydrographic survey is an important technology for improving maritime safety, especially in coastal waters. The accuracy of nautical charts and navigation publications is known to be directly related to hydrographic survey data. Therefore, this paper aims to investigate the status of a hydrographic survey by the International Hydrographic Organization (IHO) regions and identify the potentially risky IHO region for navigation safety. The fundamental step was to obtain the qualitative and quantitative data of the survey. Then, the presented analysis includes investigating the possible relationships between survey status and geographical characteristics by IHO regions. Considering that coastline length and sea surface data have not been calculated by regions, a quantum geographic information system was used to extract data. Using the presented methodology, the case study analyzes the data of stranded ships from 2010 to 2021 by IHO regions, estimates coastline length and sea surface by regions, and establishes the relationships between the coastline length, sea surface, and stranded ships. The results point out the need for improvement in the state of the hydrographic survey in almost all IHO regions and show a correlation between the sea surface and an adequate survey, as well as the coastline length and stranded ships. Hence, this research indicates the possibility of rationalizing the distribution of the IHO region concerning the sea surface and coastline length. [ABSTRACT FROM AUTHOR]

Pogledom na kartu hrvatskog dijela Jadrana, evidentna je potreba za velikim brojem objekata pomorske signalizacije (OPS) na navedenom morskom području. Istočna obala Jadrana pogodnija je za plovidbu od zapadne iz niza razloga, no njena razvijenost ipak predstavlja veliki izazov za pomorce, kojima opasnost predstavljaju skriveni grebeni, hridi, nepoznate pličine i ine stvari koje plovidbu mogu učiniti nesigurnom, kako za posadu, tako i za brodove. Objekti pomorske signalizacije se postavljaju sukladno Pravilniku o oznakama i načinu označavanja na plovnim putovima u unutarnjim morskim vodama i teritorijalnom moru Republike Hrvatske, koji je usklađen s preporukama Međunarodne organizacije za pomorsku signalizaciju – IALA i dijele se na svjetionike, obalna svjetla, lučka svjetla, signalne postaje, svjetleće i signalne oznake i plutače te oznake pokrivnog smjera. Kako bi objekti pomorske signalizacije ispravno funkcionirali, opremljeni su velikim brojem uređaja i opreme, a sam rad potrebno je neprekidno nadzirati, posebice u noćnom periodu. Ovim radom opisana je sva elektro oprema nužna za ispravan rad obalnog svjetla Rt Višnjica, koji se nalazi na samom ulazu u luku Ploče. U navedenu opremu spadaju LED izvor svjetla, solarni uređaji za napajanje te akumulatorske baterije, a posebno je obrađena i oprema za daljinski nadzor objekta pomorske signalizacije, koji uključuje određen broj senzora, PLC (programmable logic controller) uređaj i uređaj za komunikaciju. Na kraju rada opisana je nadogradnja sustava daljinskog nadzora za nadzor izvora svjetla u LED tehnologiji, a sve sa ciljem pravovremene dojave o greškama u radu objekta te u konačnici podizanja razine sigurnosti plovidbe.

In order to improve clinical care, coordinate research activities and raise awareness for the ultra-orphan Neurodegeneration with Brain Iron Accumulation (NBIA) disorders, a group of NBIA clinicians and researchers, industry partners and patient advocacies from six European countries, Canada and the US joined forces in 2010 to set-up the collaborative initiative TIRCON (Treat Iron-Related Childhood-Onset Neurodegeneration). As a research project, TIRCON received funding in the 7th Framework Programme (FP7) of the European Union (EU) from 2011 to 2015. After successful and timely completion of the initial FP7 project, funding and donations from industry and patient organizations have sustained the further development of TIRCON's dedicated clinical research infrastructure and its governance architecture, as well as the ongoing efforts undertaken in the NBIA community to establish a network of care. From the beginning, the University Hospital of the Ludwig-Maximilians-University in Munich, Germany has been coordinating the TIRCON initiative. It consists of 8 work packages, of which the first double-blind, placebo-controlled, randomized, multi-site clinical trial in NBIA (deferiprone in PKAN, completed) and a global patient registry and biobank, currently comprising baseline and follow-up data of > 400 NBIA patients have gained particular importance. Here we describe TIRCON's history with all the challenges and achievements in diagnosing and treating NBIA. Today, TIRCON lays the ground for future clinical care and research. In these times, it may also serve as a good example of well-directed governmental funding and fruitful international scientific collaboration.

Neurodegeneration with Brain Iron Accumulation (NBIA) is a heterogeneous group of progressive neurodegenerative diseases characterized by iron deposition in the globus pallidus and the substantia nigra. As of today, 15 distinct monogenetic disease entities have been identified. The four most common forms are pantothenate kinase-associated neurodegeneration (PKAN), phospholipase A2 group VI (PLA2G6)-associated neurodegeneration (PLAN), beta-propeller protein-associated neurodegeneration (BPAN) and mitochondrial membrane protein-associated neurodegeneration (MPAN). Neurodegeneration with Brain Iron Accumulation disorders present with a wide spectrum of clinical symptoms such as movement disorder signs (dystonia, parkinsonism, chorea), pyramidal involvement (e.g., spasticity), speech disorders, cognitive decline, psychomotor retardation, and ocular abnormalities. Treatment remains largely symptomatic but new drugs are in the pipeline. In this review, we discuss the rationale of new compounds, summarize results from clinical trials, provide an overview of important results in cell lines and animal models and discuss the future development of disease-modifying therapies for NBIA disorders. A general mechanistic approach for treatment of NBIA disorders is with iron chelators which bind and remove iron. Few studies investigated the effect of deferiprone in PKAN, including a recent placebo-controlled double-blind multicenter trial, demonstrating radiological improvement with reduction of iron load in the basal ganglia and a trend to slowing of disease progression. Disease-modifying strategies address the specific metabolic pathways of the affected enzyme. Such tailor-made approaches include provision of an alternative substrate (e.g., fosmetpantotenate or 4'-phosphopantetheine for PKAN) in order to bypass the defective enzyme. A recent randomized controlled trial of fosmetpantotenate, however, did not show any significant benefit of the drug as compared to placebo, leading to early termination of the trials' extension phase. 4'-phosphopantetheine showed promising results in animal models and a clinical study in patients is currently underway. Another approach is the activation of other enzyme isoforms using small molecules (e.g., PZ-2891 in PKAN). There are also compounds which counteract downstream cellular effects. For example, deuterated polyunsaturated fatty acids (D-PUFA) may reduce mitochondrial lipid peroxidation in PLAN. In infantile neuroaxonal dystrophy (a subtype of PLAN), desipramine may be repurposed as it blocks ceramide accumulation. Gene replacement therapy is still in a preclinical stage.

- Abstract
Background: Variants in genes of the nucleotide excision repair (NER) pathway have been associated with heterogeneous clinical presentations ranging from xeroderma pigmentosum to Cockayne syndrome and trichothiodystrophy. NER deficiencies manifest with photosensitivity and skin cancer, but also developmental delay and early‐onset neurological degeneration. Adult‐onset neurological features have been reported in only a few xeroderma pigmentosum cases, all showing at least mild skin manifestations. Objective: The aim of this multicenter study was to investigate the frequency and clinical features of patients with biallelic variants in NER genes who are predominantly presenting with neurological signs. Methods: In‐house exome and genome datasets of 14,303 patients, including 3543 neurological cases, were screened for deleterious variants in NER‐related genes. Clinical workup included in‐depth neurological and dermatological assessments. Results: We identified 13 patients with variants in ERCC4 (n = 8), ERCC2 (n = 4), or XPA (n = 1), mostly proven biallelic, including five different recurrent and six novel variants. All individuals had adult‐onset progressive neurological deterioration with ataxia, dementia, and frequently chorea, neuropathy, and spasticity. Brain magnetic resonance imaging showed profound global brain atrophy in all patients. Dermatological examination did not show any skin cancer or pronounced ultraviolet damage. Conclusions: We introduce NERDND as adult‐onset neurodegeneration (ND) within the spectrum of autosomal recessive NER disorders (NERD). Our study demonstrates that NERDND is probably an underdiagnosed cause of neurodegeneration in adulthood and should be considered in patients with overlapping cognitive and movement abnormalities. © 2022 The Authors.

Definiranjem problema ovog rada zaključili smo da je problem nezaposlenosti egzistencijalni problem svakog pojedinca i zajednice. Smanjenjem stope nezaposlenosti postepeno se unaprijeđuje cijelo gospodarstvo. Nezaposlenost najjizravnije je vezana uz BDP koji je najreprezentativniji pokazatelj razvitka gospodarstva. Također, nezaposlenost ima veliki utjecaj na moral stanovništva. Velika stopa nezaposlenosti može utjecati na psihu ljudi te se smatra jednim od najvažnijih problema čovječanstva. Hrvatska se trenutno nalazi u fazi ekonomskog prosperiteta. Zahvaljujući djelovanju aktivne politike zapošljavanja, stopa nezaposlenosti iz godine u godinu sve je manja i manja. Prema podacima iz Hrvatskog zavoda za zapošljavanje, sve županije bilježe pad stope nezaposlenosti, a najveći pad ima Koprivničko-križecačka županija (69,99%). Razvojem gospodarstva Hrvatske vrlo zadovoljni su mladi ljudi (15-19 godina) jer su oni dobna skupina koja bilježi najveći pad stope nezaposlenosti. S druge strane, budućnost svjetske, tako i hrvatske ekonomije je pred izazovom globalne pandemije uzrokovane virusom COVID-19. Daljna situacija ima dva moguća scenarija. Prvi scenarij je taj da će ova pandemija biti kratkotrajna te da će se ekonomija samo malo destabilizirati. Drugi scenarij, koji nije tako vedar, je taj da će ova pandemija potrajati duže vrijeme i pretvoriti se u veliku ekonomsku krizu. Za drugi scenarij nijedna svjetska ekonomija nema rješenja, te u slučaju dugotrajne pandemija, posljedice na gospodarstvo Hrvatske pa tako i na stopu nezaposlenosti biti će drastične. Cilj ovoga rada usmjeren je na analizu i prognoziranje nezaposlenosti u Hrvatskoj. Daje se pregled strukture i kretanja nezaposlenosti u razdoblju od 2015. do 2020. godine te predviđanja kretanja nezaposlenosti s obzirom na trenutnu situaciju u državi. U radu se također donose prijedlozi mjera za smanjenje stope nezaposlenosti. By defining the problem of this paper, we can conclude that the problem of unemployment is an existential problem of an each individual and a community. By lowering the unemployment rate, the economy benefits gradually. Unemployment is directly bonded with GDP which is considered the most representative indicator of economic development. Unemployment has a great influence on the moral of a population as well. A high unemployment rate can affect the the psyche of people and is considered one of the greatest problems of humanity. Croatia is currently in the phase of economic prosperity. Beacause of the doings of active employment policy, the unemployment rate is lowering year by year. Considering the data from Croatian Employment Service, all of the counties record a drop in unemployment rate and the greates drop is recorded in Koprivničko-križevačka countie (69,99%). Young people in Croatia (age 15-19) are quite pleased with the economical growth because their age group records the largest drop in of unemployment rate. On the other hand, the future of the global, as well as the Croatian economy is facing a huge test of a global pandemic caused by the virus COVID-19. The situation can have two scenarios. The first scenario is that this pandemic is going to be short-lived and that the economy is going to have a minor setback. The other scenario, which is not very bright, is that this pandemic is going to be long-lasting and will transform into a great economical crisis. For the second scenario, none of the world's economies have a solution and if there is going to be a long-lasting pandemic, the effects on the economy of Croatia are going to be drastic. The goal of this paper is focused towards analysing and predicting the unemployment in Croatia. It presents the details of unemployment in the period of 2015. up to 2019. and predicts the possible movement of unemployment considering the current situation in the country. The paper also presents suggestions on what measures can be implemented to lower the unemployment rate.

- Abstract
Objective To assess neurofilaments as neurodegenerative biomarkers in serum of patients with Friedreich's ataxia. Methods Single molecule array measurements of neurofilament light (NfL) and heavy chain (pNfH) in 99 patients with genetically confirmed Friedreich's ataxia. Correlation of NfL/pNfH serum levels with disease severity, disease duration, age, age at onset, and GAA repeat length. Results Median serum levels of NfL were 21.2 pg/ml (range 3.6-49.3) in controls and 26.1 pg/ml (0-78.1) in Friedreich's ataxia (p = 0.002). pNfH levels were 23.5 pg/ml (13.3-43.3) in controls and 92 pg/ml (3.1-303) in Friedreich's ataxia (p = 0.0004). NfL levels were significantly increased in younger patients (age 16-31 years, p < 0.001) and patients aged 32-47 years (p = 0.008), but not in patients of age 48 years and older (p = 0.41). In a longitudinal assessment, there was no difference in NfL levels in 14 patients with repeated sampling 2 years after baseline measurement. Levels of NfL correlated inversely with GAA1 repeat length (r = - 0.24, p = 0.02) but not with disease severity (r = - 0.13, p = 0.22), disease duration (r = - 0.06, p = 0.53), or age at onset (r = 0.05, p = 0.62). Conclusion Serum levels of NfL and pNfH are elevated in Friedreich's ataxia, but differences to healthy controls decrease with increasing age. Long-term longitudinal data are required to explore whether this reflects a selection bias from early death of more severely affected individuals or a slowing down of the neurodegenerative process with age. In a pilot study over 2 years of follow-up-a period relevant for biomarkers indicating treatment effects-we found NfL levels to be stable.

The Adriatic Sea is covered with a large number of maritime signalling facilities, including light and signal buoys, which mark the waterways at precisely determined positions. In order for the buoys to perform their function correctly, their correct positioning is crucial. Therefore, to control the buoys position it is necessary to implement a system of constant monitoring of their position, which is not established in the Croatian part of the Adriatic yet. This paper discusses the available options for establishing such system, and it brings the results of an experimental test-device implementation on a real buoy in the Split sea area. The conclusion is made based on the experimental results, as well as the recommendation about requirements and limitation of the system.

OBJECTIVE: To provide a systematic evaluation of the broad clinical variability in Friedreich ataxia (FRDA), a multisystem disorder presenting mainly with afferent ataxia but also a complex phenotype of nonataxia symptoms. METHODS: From the large database of the European Friedreich's Ataxia Consortium for Translational Studies, 650 patients with genetically confirmed FRDA were included. Detailed data of medical history documentation, questionnaires, and reports on clinical features were analyzed to provide in-depth description of the clinical profile and frequency rates of phenotypical features with a focus on differences between typical-onset and late-onset FRDA. Logistic regression modeling was used to identify predictors for the presence of the most common clinical features. RESULTS: The most frequent clinical features beyond afferent ataxia were abnormal eye movements (90.5%), scoliosis (73.5%), deformities of the feet (58.8%), urinary dysfunction (42.8%), cardiomyopathy and cardiac hypertrophy (40.3%), followed by decreased visual acuity (36.8%); less frequent features were, among others, depression (14.1%) and diabetes (7.1%). Most of these features were more common in the typical-onset group compared to the late-onset group. Logistic regression models for the presence of these symptoms demonstrated the predictive value of GAA repeat length on the shorter allele and age at onset, but also severity of ataxia signs, sex, and presence of neonatal problems. CONCLUSIONS: This joint European effort demonstrates the multisystem nature of this neurodegenerative disease encompassing most the central nervous, neuromuscular, cardiologic, and sensory systems. A distinct and deeper knowledge of this rare and chronic disease is highly relevant for clinical practice and designs of clinical trials., SCOPUS: ar.j, info:eu-repo/semantics/published

postal parcels ,influence of the season ,exponential trend model - Abstract
In the last couple of years, the Republic of Croatia has witnessed a growth in the number of postal parcels. In this paper, by applying quantitative methods, we perform the decomposition of a time series, where the development of the number of parcels is decomposed into the part which refers to the influence of the season and the part which refers to the irregular component, i.e. the unexplained part. We also perform an estimate of the developments of the number of parcels until 2025 by using the exponential trend, where the developments of the parcel number variable are estimated without the influence of the season. The research has established the influence of the season, where highest parcel traffic is achieved in the fourth quarters. By applying the exponential trend model, it has been established that in every following period, a growth in the number of parcels by 2.75% is to be expected.

- Abstract
Background: Sensitive outcome measures for clinical trials on cerebellar ataxias are lacking. Most cerebellar ataxias progress very slowly and quantitative measurements are required to evaluate cerebellar dysfunction. Methods: We evaluated two scales for rating cerebellar ataxias: the Composite Cerebellar Functional Severity (CCFS) Scale and Scale for the Assessment and Rating of Ataxia (SARA), in patients with spinocerebellar ataxia (SCA) and controls. We evaluated these scales for different diseases and investigated the factors governing the scores obtained. All patients were recruited prospectively. Results: There were 383 patients with Friedreich's ataxia (FRDA), 205 patients with SCA and 168 controls. In FRDA, 31% of the variance of cerebellar signs with the CCFS and 41% of that with SARA were explained by disease duration, age at onset and the shorter abnormal repeat in the FXN gene. Increases in CCFS and SARA scores per year were lower for FRDA than for SCA (CCFS index: 0.123±0.123 per year vs 0.163±0.179, P<0.001; SARA index: 1.5±1.2 vs 1.7±1.7, P<0.001), indicating slower cerebellar dysfunction indexes for FRDA than for SCA. Patients with SCA2 had higher CCFS scores than patients with SCA1 and SCA3, but similar SARA scores. Conclusions: Cerebellar dysfunction, as measured with the CCFS and SARA scales, was more severe in FRDA than in patients with SCA, but with lower progression indexes, within the limits of these types of indexes. Ceiling effects may occur at late stages, for both scales. The CCFS scale is rater-independent and could be used in a multicentre context, as it is simple, rapid and fully automated., SCOPUS: ar.j, info:eu-repo/semantics/published

Foreign exchange ,Yields ,Volatility ,Eurozone - Abstract
This paper studies the impact of yields movements on the long-term sovereign bonds on foreign exchange volatility in the Eurozone from the beginning of 2003 to the end of 2013. Using such a period of time allowed us to carry out separate analysis before and after the global financial crisis. Namely, today in the world of free financial flows the exchange rate is one of the most important indicators of the country’s stability. After the emergence of the global financial crisis, state stability is again in the main focus of investors. The Eurozone countries rocked the debt crisis after the global financial crisis. One of the specificities of the Eurozone compared to the rest of the world is that a common currency exists, while all member states are issuing government bonds individually and have a separate fiscal policy. With the arrival of turbulence in financial markets, investors have different perceptions of the quality of government bonds of member countries. A change of government bond yields indicates, also, a change in the perception of risk of investing in the financial assets of countries from the Eurozone. This changed perception of risk is causing the movement of capital among countries and consequently is resulting in a change in the Euro and US dollar exchange rate. The results of our empirical study proved that three member states have the greatest impacts on the movement of capital between Euro and Dollar assets: namely Luxembourg, the Netherlands and Germany.

- Abstract
Background: Friedreich's ataxia is a rare autosomal recessive neurodegenerative disorder. Here we report cross-sectional baseline data to establish the biological and clinical characteristics for a prospective, international, European Friedreich's ataxia database registry. Methods: Within the European Friedreich's Ataxia Consortium for Translational Studies (EFACTS) framework, we assessed a cohort of patients with genetically confirmed Friedreich's ataxia. The primary outcome measure was the Scale for the Assessment and Rating of Ataxia (SARA) and secondary outcome measures were the Inventory of Non-Ataxia Signs (INAS), the performance-based coordination test Spinocerebellar Ataxia Functional Index (SCAFI), the neurocognitive phonemic verbal fluency test, and two quality-of-life measures: the activities of daily living (ADL) part of the Friedreich's Ataxia Rating Scale and EQ-5D. The Friedreich's ataxia cohort was subdivided into three groups: early disease onset (≤14 years), intermediate onset (15-24 years), and late onset (≥25 years), which were compared for clinical characteristics and outcome measures. We used linear regression analysis to estimate the annual decline of clinical outcome measures based on disease duration. This study is registered with ClinicalTrials.gov, number NCT02069509. Findings: We enrolled 592 patients with genetically confirmed Friedreich's ataxia between Sept 15, 2010, and April 30, 2013, at 11 sites in seven European countries. Age of disease onset was inversely correlated with the number of GAA repeats in the frataxin (. FXN) gene: every 100 GAA repeats on the smaller repeat allele was associated with a 2·3 year (SE 0·2) earlier onset. Regression analyses showed significant estimated annual worsening of SARA (regression coefficient 0·86 points [SE 0·05], INAS (0·14 points [0·01]), SCAFI Z scores (-0·09 [0·01]), verbal fluency (-0·34 words [0·07]), and ADL (0·64 points [0·04]) during the first 25 years of disease; the regression slope f, SCOPUS: ar.j, info:eu-repo/semantics/published

inteligencija ,osobine ličnosti ,vođenje - Abstract
Istraživanjem se nastojalo utvrditi postoji li razlika u općoj inteligenciji i u određenim osobinama ličnosti između vojnika, dočasnika i časnika, a svi su dragovoljci i ratni veterani, a u trenutku pristupanja u Hrvatsku vojsku svi su bili srednje stručne spreme i bez formalne vojne izobrazbe. U svakoj skupini je bilo po 60 ispitanika. Pokazalo se da postoji statistički značajna razlika u inteligenciji između vojnika i časnika (časnici su inteligentniji), dok razlika u inteligenciji između vojnika i dočasnika te između dočasnika i časnika nije utvrđena kao statistički značajna. Dakle, inteligencija je bila značajna determinanta za postignut položaj u vojnoj hijerarhiji. Postoji statistički značajna razlika između vojnika i časnika po dimenzijama „Reprodukcija“ i „Deprivacija“ Plutchikovog Indeksa profila emocija (PIE). Na dimenziji „Reprodukcija“ vojnici su postigli statistički značajno niži, a na dimenziji „Deprivacija“ statistički značajno viši rezultat od časnika. Po ostalim dimenzijama upitnika osobnosti PIE tri skupine ispitanika ne razlikuju se statistički značajno. Razmjerno male razlike po određenim dimenzijama upitnika ličnosti PIE su bile očekivane s obzirom da je na ispitanicima sve tri skupine u sklopu ulaznog zdravstvenog pregleda napravljena psihologijska selekcija za ulazak u profesionalni sastav, odnosno da su selekcionirani po pitanju strukture osobnosti poželjne za vojnički poziv. Dobiveni su trendovi razlika u ličnosti u funkciji položaja u zapovjednoj hijerarhiji sukladni dosadašnjim znanstvenim spoznajama u tom području psihologije.

- Abstract
Mitochondrial disease is a group of rare conditions, with no approved treatment to date, except for Leber hereditary optic neuropathy. Therapeutic options to alleviate the symptoms of mitochondrial disease are urgently needed. Sonlicromanol is a promising candidate, as it positively alters the key metabolic and inflammatory pathways associated with mitochondrial disease. Sonlicromanol is a reductive and oxidative distress modulator, selectively inhibiting microsomal prostaglandin E1 synthase activity. This Phase 2b program, aiming at evaluating sonlicromanol in adults with m.3243A>G mutation and primary mitochondrial disease, consisted of a randomized controlled (RCT) study (dose-selection) followed by a 52-week open-label extension study (EXT, long-term tolerability, safety, and efficacy of sonlicromanol). Patients were randomized (1:1:1) to receive 100- or 50-mg sonlicromanol, or placebo twice daily (bid) for 28 days with ≥2-week wash-out period between treatments. Patients who completed the RCT study entered the EXT study wherein they received 100-mg sonlicromanol bid. Overall, 27 patients were randomized (24 RCT patients completed all periods). 15 patients entered the EXT, and 12 patients were included in the EXT analysis set. All patients reported good tolerability and favourable safety, with pharmacokinetic results comparable to the earlier Phase 2a study. The RCT primary endpoint (change from placebo in the attentional domain of cognition score [IDN: visual identification, Cogstate]) did not reach statistical significance. Using a categorisation of the subject's period baseline a treatment effect over placebo was observed if their baseline was more affected (p=0.0338). Using this approach, there were signals of improvements over placebo in at least one dose in the Beck Depression Inventory (BDI, p=0.0143), Cognitive Failure Questionnaire (CFQ, p=0.0113), and the Depression subscale of the Hospital Anxiety and Depression Scale (p=0.0256). Statistically and/or clinically meaningful improvements were observed in the patient- and clinician-reported outcome measures at the end of the EXT study (Test of attentional performance [TAP] with alarm, p=0.0102; TAP without alarm, p=0.0047; BDI somatic, p=0.0261; BDI Total, p=0.0563; SF12 physical component score, p=0.0008). Seven of nine domains of RAND-Short form-36 like SF-36 pain improved (p=0.0105). Other promising results were observed in Neuro QoL-Fatigue-SF (p=0.0036), MiniBESTest (p=0.0009), McGill Pain Questionnaire (p=0.0105), EQ-5D-5L-VAS (p=0.0213) and EQ-5D-5L-index (p=0.0173). Most patients showed improvement in the 5× sit-to-stand test. Sonlicromanol was well-tolerated and demonstrated a favourable benefit/risk ratio for up to one year. Sonlicromanol was efficacious in patients when affected at baseline, as seen across a variety of clinically relevant domains. Long-term treatment showed more pronounced changes from baseline., (© The Author(s) 2024. Published by Oxford University Press on behalf of the Guarantors of Brain.)

- Abstract
Mitochondrial membrane protein-associated neurodegeneration (MPAN) is an ultraorphan neurogenetic disease from the group of neurodegeneration with brain iron accumulation (NBIA) disorders. Here we report cross-sectional and longitudinal data to define the phenotype, to assess disease progression and to estimate sample sizes for clinical trials. We enrolled patients with genetically confirmed MPAN from the Treat Iron-Related Childhood-Onset Neurodegeneration (TIRCON) registry and cohort study, and from additional sites. Linear mixed-effect modelling (LMEM) was used to calculate annual progression rates for the Unified Parkinson's Disease Rating Scale (UPDRS), Barry-Albright Dystonia (BAD) scale, Schwab and England Activities of Daily Living (SE-ADL) scale and the Pediatric Quality of Life Inventory (PedsQL). We investigated 85 MPAN patients cross-sectionally, with functional outcome data collected in 45. Median age at onset was 9 years and the median diagnostic delay was 5 years. The most common findings were gait disturbance (99%), pyramidal involvement (95%), dysarthria (90%), vision disturbances (82%), with all but dysarthria presenting early in the disease course. After 16 years with the disease, 50% of patients were wheelchair dependent. LMEM showed an annual progression rate of 4.5 points in total UPDRS. The total BAD scale score showed no significant progression over time. The SE-ADL scale and the patient- and parent-reported PedsQL showed a decline of 3.9%, 2.14 and 2.05 points, respectively. No patient subpopulations were identified based on longitudinal trajectories. Our cross-sectional results define the order of onset and frequency of symptoms in MPAN, which will inform the diagnostic process, help to shorten diagnostic delay and aid in counselling patients, parents and caregivers. Our longitudinal findings define the natural history of MPAN, reveal the most responsive outcomes and highlight the need for an MPAN-specific rating approach. Our sample size estimations inform the design of upcoming clinical trials., (© The Author(s) 2023. Published by Oxford University Press on behalf of the Guarantors of Brain. All rights reserved.
