The circadian clock in choroid plexus (ChP) controls processes involved in its physiological functions, but the signals that synchronize the clock have been sparsely studied. We found that the ChP clock in the fourthventricle (4V) is more robust than that in the lateral ventricle (LV) and investigated whether both clocks use information about mealtime as a signal to synchronize with the current activity state. Exposure of mPer2Luc mice to a 10-day reverse restricted feeding (rRF) protocol, in which food was provided for 6 h during daytime, advanced the phase of the ChP clock in 4V and LV, as evidenced by shifted (1) PER2-driven bioluminescence rhythms of ChP explants ex vivo and (2) daily profiles in clock gene expression in both ChP tissues in vivo. In contrast, clocks in other brain regions (DMH, ARC, LHb) of the same mice did not shift. The 4V ChP responded more strongly than the LV ChP to rRF by modulating the expression of genes to ensure a decrease in resistance to cerebrospinal fluid drainage and increase the secretory capacity of ChP cells. Mechanistically, rRF affects the ChP clock through food-induced increases in insulin, glucose and temperature levels, as in vitro all three signals significantly shifted the clocks in both ChP tissues, similar to rRF. The effect of glucose was partially blocked by OSMI-1, suggesting involvement of O-linked N-acetylglucosamine posttranslational modification. We identified mechanisms that can signal to the brain the time of feeding and the associated activity state via resetting of the ChP clock.

BACKGROUND: The development of child's lifestyle occurs within regular 24-hour movement patterns under the guidance of parents. Accelerometer-based monitoring allows for the capture of these 24-hour movement patterns of behaviour. Therefore, the aim of this study was to reveal whether active participation in organised physical activity (OPA) contributed to the achievement of the World Health Organization's (WHO) 24-hour movement behaviour guidelines (24-hMBGS) among 3-10-year-old children, considering the influence of parents' movement behaviour and families' material background. METHODS: The 24-hour movement behaviour (24-hMB) of 348 child-parent pairs (with at least one parent) was continuously monitored for 7 days via ActiGraph accelerometers placed on the non-dominant wrist. Children's adherence to the WHO's 24-hMBGS was analysed using logistic regression analysis. The socioeconomic status (SES) of families was measured using the Family Affluence Scale. Body mass level was determined according to body mass index gender- and age-specific WHO reference data. Univariate analysis of variance/Pearson's chi-square test was used to test differences in sedentary behaviour duration/excess body weight between active participants and non-participants in OPA. RESULTS: Active 3-10-year-old participants in OPA, compared to non-participants, were significantly more likely to meet at least two of the 24-hMBGS (77.7% vs. 66.4%, p = 0.008), had significantly shorter daily sedentary time (by 30 min per day, p = 0.001), and a significantly lower prevalence of excessive body weight (10.26% vs. 24.87% p < 0.001). Engaging in OPA significantly (p < 0.01) helped 3-10-year-old children achieve at least two of the 24-hMBGS, regardless of their gender, age, excess body weight, or family SES. In addition, a mother's non-excessive body weight and achievement of at least two of the WHO's 24-hMBGS significantly (p < 0.05) contributed to children attaining at least two of the WHO's 24-hMBGS. CONCLUSIONS: Even in young children, active participation in OPA tend to contribute to a healthier lifestyle profile, characterised by shorter sedentary behaviour and lower excess body weight, with a significant influence from the mother's movement behaviour.

AIM: Exposure to light at night and meal time misaligned with the light/dark (LD) cycle-typical features of daily life in modern 24/7 society-are associated with negative effects on health. To understand the mechanism, we developed a novel protocol of complex chronodisruption (CD) in which we exposed female rats to four weekly cycles consisting of 5-day intervals of constant light and 2-day intervals of food access restricted to the light phase of the 12:12 LD cycle. METHODS: We examined the effects of CD on behavior, estrous cycle, sleep patterns, glucose homeostasis and profiles of clock- and metabolism-related gene expression (using RT qPCR) and liver metabolome and lipidome (using untargeted metabolomic and lipidomic profiling). RESULTS: CD attenuated the rhythmic output of the central clock in the suprachiasmatic nucleus via Prok2 signaling, thereby disrupting locomotor activity, the estrous cycle, sleep patterns, and mutual phase relationship between the central and peripheral clocks. In the periphery, CD abolished Per1,2 expression rhythms in peripheral tissues (liver, pancreas, colon) and worsened glucose homeostasis. In the liver, it impaired the expression of NAD+, lipid, and cholesterol metabolism genes and abolished most of the high-amplitude rhythms of lipids and polar metabolites. Interestingly, CD abolished the circadian rhythm of Cpt1a expression and increased the levels of long-chain acylcarnitines (ACar 18:2, ACar 16:0), indicating enhanced fatty acid oxidation in mitochondria. CONCLUSION: Our data show the widespread effects of CD on metabolism and point to ACars as biomarkers for CD due to misaligned sleep and feeding patterns.

BACKGROUND: Detrimental effects of misinformation were observed during the COVID-19 pandemic. Presently, amid Russia's military aggression in Ukraine, another wave of misinformation is spreading on the web and impacting our daily lives, with many citizens and politicians embracing Russian propaganda narratives. Despite the lack of an objective connection between these 2 societal issues, anecdotal observations suggest that supporters of misinformation regarding COVID-19 (BM-C) have also adopted misinformation about the war in Ukraine (BM-U) while sharing similar media use patterns and political attitudes. OBJECTIVE: The aim of this study was to determine whether there is a link between respondents' endorsement of the 2 sets of misinformation narratives, and whether some of the selected factors (media use, political trust, vaccine hesitancy, and belief rigidity) are associated with both BM-C and BM-U. METHODS: We conducted a survey on a nationally representative sample of 1623 individuals in the Czech Republic. Spearman correlation analysis was performed to identify the relationship between BM-C and BM-U. In addition, multiple linear regression was used to determine associations between the examined factors and both sets of misinformation. RESULTS: We discovered that BM-C and BM-U were moderately correlated (Spearman ρ=0.57; P<.001). Furthermore, increased trust in Russia and decreased trust in the local government, public media, and Western allies of the Czech Republic predicted both BM-C and BM-U. Media use indicating frustration with and avoidance of public or mainstream media, consumption of alternative information sources, and participation in web-based discussions indicative of epistemic bubbles predicted beliefs in misinformation narratives. COVID-19 vaccine refusal predicted only BM-C but not BM-U. However, vaccine refusers were overrepresented in the BM-U supporters (64/161, 39.8%) and undecided (128/505, 25.3%) individuals. Both beliefs were associated with belief rigidity. CONCLUSIONS: Our study provides empirical evidence that supporters of COVID-19 misinformation were susceptible to ideological misinformation aligning with Russian propaganda. Supporters of both sets of misinformation narratives were primarily linked by their shared trust or distrust in the same geopolitical actors and their distrust in the local government.

BACKGROUND: Minimalistic footwear provides adequate toe space, tripod function, improving foot function, muscle activation and stability during walking similarly to barefoot walking. Due to the increasing popularity of this specific footwear, there is a lack of research focusing on general users of minimalistic footwear. RESEARCH QUESTION: Does annual walking in minimalistic footwear affect gait biomechanics? METHODS: Cross-sectional study involving twenty participants in a minimalistic footwear group with both experience (MFE) and no experience (NMFE). Participants walked in three different conditions (barefoot, minimalistic, and neutral footwear) in the laboratory at normal human walking speed. RESULTS: A significant main effect of groups regardless of footwear conditions show significantly greater values during walking in minimalistic footwear and barefoot in the stride length (p=0.035, p=0.003, respectively), and stride width (p=0.047, p=0.028, respectively) in the NMFE group compared to MFE group. The significant differences in the main effects of footwear regardless of experience were found in stance time (p<0.001), steps per minute (p<0.001), stride length (<0.001), foot adduction in TO (p<0.001), foot eversion angle in IC and TO (p<0.001, p<0.001, respectively), foot progression angle (p<0.001), ankle dorsiflexion angle in IC and TO (p<0.001, p<0.001, respectively), in ankle eversion angle in IC and TO (p<0.001, p<0.001, respectively), knee flexion angle in IC and TO (p<0.001; p<0.001, respectively), and in knee flexion range of motion (p<0.001). SIGNIFICANCE: Based on our findings, barefoot walking should be used primarily during daily activities if the environment is conducive. Only one year of experience with minimalistic footwear seems insufficient and an intervention should be incorporated to change the gait pattern when transitioning to full minimalistic footwear walking.

Primárna progresívna afázia (PPA) je klinický syndróm, ktorý vzniká na podklade neurodegeneratívneho procesu. PPA je charakteristická postupným rozpadom jazykového systému. Symptómy ochorenia sa najčastejšie manifestujú okolo 50. roku života, no vyskytujú sa aj u čoraz mladšej populácie. Oboznámenie sa s takýmto typom diagnózy predstavuje pre pacienta určitú psychickú záťaž. Vyrovnávanie sa s diagnózou závisí od osobnostných čŕt pacienta (Nash, Hutner a Caligor, 2014). Neadekvátne spracovanie stresu a psychickej záťaže môže viesť k rozvoju funkčnej poruchy hybnosti (Thenganatt a Jankovic, 2015). Prezentujeme kazuistiku 38-ročnej pacientky s anamnézou tri roky trvajúcej poruchy reči. Subjektívne udávané ťažkosti sa týkali najmä aktualizácie a komolenia slov. Pacientka podstúpila komplexnú neurologickú diagnostiku a bolo jej doplnené PET CT s nálezom zmien zodpovedajúcim lvPPA. Krátko po oznámení diagnózy sa u pacientky začali vyskytovať meniace sa vzorce motorického narušenia reči, ktoré výrazne limitujú ďalšiu diagnostiku a zároveň aj terapiu. Pacientke bolo odporučené psychologické a psychiatrické vyšetrenie. Kazuistika upozorňuje na dôležitosť multiodborovej spolupráce.

Primary progressive aphasia (PPA) is a clinical syndrome caused by a neurodegenerative process. PPA is characterised by a progressive disruption of the language system, which limits the patient in activities of daily living. The symptoms of this disease mostly manifest around 50 years of age, but are often seen in a much younger population. Acquaintance with this kind of diagnosis represents a certain psychological burden to the patient. Coping with it depends on the patient's personality traits (Nash, Hutner and Caligor, 2014). Inadequate stress processing can lead to development of a functional movement disorder (Thenganatt and Jankovic, 2015). Here we present a case report of a 38-year-old female patient with a 3-year history of a speech disorder. She subjectively stated difficulties, mainly related to word finding difficulties and garbled words. The patient underwent a comprehensive neurological examination. A PET CT scan was performed, with findings of changes corresponding to lvPPA. Shortly after the diagnosis was announced, the patient began to experience changing patterns of motor speech impairment, which significantly limit the further diagnostic and therapeutic processes. A psychological and psychiatric examination was recommended to the patient. This case report draws attention to the importance of multidisciplinary cooperation.

Úvod: Depresivní porucha, jako jedno z nejčastějších duševních onemocnění, nepříznivě ovlivňuje životy a zdravotní stav mnoha lidí po celém světě. Vyskytuje se v jakémkoliv věku, nejčastěji však mezi 20. a 40. rokem života. Celosvětově trpí každoročně depresivními poruchami přibližně 100 milionů lidí, přičemž u řady jedinců je terapie doprovázena částečnou léčebnou odpovědí nebo přímo rezistencí k léčbě, což trvale zvyšuje potřebu hledání efektivních strategií prevence a léčby, ale také průběžné monitorování a vyhodnocování aktuálně využívaných přístupů v běžné klinické praxi. Materiály a metody: Šířeji koncipovaná studie s pracovním názvem UMBRELLA byla neintervenční, observační, multicentrická studie, jejíž první etapa je zaměřená na tzv. "real world evidence" důvodů pro změnu psychofarmakologické léčby a jejího detailního charakteru u pacientů trpících depresivní epizodou periodické depresivní poruchy. Do závěrečného vyhodnocení byla zařazena data 267 pacientů léčených v psychiatrických ambulancích v České republice, které na sondě mapující reálnou klinickou praxi participovaly. Výsledky: Analyzována byla data od 74 mužů (27,7 %) a 193 žen (72,3 %) s průměrným věkem 49 let. Změny léčby byly prováděny lékařem na základě vyhodnocení přítomných reziduálních příznaků onemocnění, přičemž nejčastějšími problémy byly perzistující depresivní nálada, únava a anhedonie. Nejčastěji používané léčivé přípravky zahrnovaly antidepresiva (např. escitalopram, venlafaxin, sertralin), atypická antipsychotika (např. quetiapin) a klasická antipsychotika (např. chlorprothixen). Úprava farmakologické léčby byla nejčastěji provedena manipulací s antidepresivy, změnou účinné látky či úpravami jejich denních dávek. Diskuse a závěr: Předkládaná naturalistická observační studie zmapovala důvody pro změnu farmakologického přístupu a vlastní charakter nově zvolené léčebné strategie. Zjištěná heterogenita způsobů manipulace s farmakologickou léčbou potvrzuje, že léčba depresivních epizod v klinické praxi probíhá individualizovaným postupem u každého jednotlivého pacienta. Zde narážíme na snahu po uplatňování doporučených postupů v léčbě tohoto rozšířeného duševního onemocnění, které velmi efektivně popisují léčbu iniciálních epizod a v případě opakovaných epizod by také měly obsahovat základní principy terapeutického přístupu k řešení této problematiky. Zjištění, že i v rámci opakovaných epizod periodické depresivní poruchy lze efektivně zasáhnout zvýšením dávky antidepresiva nebo jeho změnou, podporuje snahu po edukaci specialistů i praktických lékařů v těchto bazálních postupech léčby. Celkově studie přináší informace reflektující běžnou klinickou praxi a podtrhuje význam iniciace strategie změny farmakologického přístupu u každého pacienta, v kterékoliv etapě léčby tohoto duševního onemocnění.

Introduction: Depressive disorder, as one of the most common mental illnesses, adversely affects the lives and health of many people around the world. It occurs at any age, but most commonly between the ages of 20 and 40. Worldwide, approximately 100 million people suffer from depressive disorders each year, with many individuals experiencing partial treatment response or treatment resistance, which continually increases the need to find effective prevention and treatment strategies, as well as to monitor and evaluate currently used approaches in routine clinical practice. Materials and methods: The more broadly conceived study, working title UMBRELLA, was a non-interventional, observational, multicentre study, the first phase of which focused on the so-called "real world evidence? of reasons for changing psychopharmacological treatment and its detailed nature in patients suffering from a depressive episode of periodic depressive disorder. The final evaluation included data from 267 patients treated in psychiatric outpatient clinics in the Czech Republic that participated in the probe into their own clinical practice. Results: Data from 74 men (27.7%) and 193 women (72.3%) with a mean age of 49 years were analysed. Changes in treatment were made by the physician based on an assessment of the residual symptoms present, with persistent depressed mood, fatigue and anhedonia being the most common problems. The most commonly used medications included antidepressants (e.g., escitalopram, venlafaxine, sertraline), atypical antipsychotics (e.g., quetiapine), and classic antipsychotics (e.g., chlorprothixene). Adjustments to pharmacological treatment were most commonly made by manipulating antidepressants, changing the active ingredient, or modifying their daily doses. Discussion and conclusion: The present naturalistic observational study mapped the reasons for the change in pharmacological approach and the actual nature of the newly chosen treatment strategy. The observed heterogeneity of pharmacological treatment manipulation patterns confirms that the treatment of depressive episodes in clinical practice follows an individualized approach for each individual patient. Here, we encounter a desire for the application of recommended practices in the treatment of this widespread mental illness, which very effectively describe the treatment of initial episodes and, in the case of recurrent episodes, should provide the basic principles of a therapeutic approach to the management of this problem. The finding that, even in the context of recurrent episodes of periodic depressive disorder, effective intervention can be achieved by increasing the dose of antidepressant medication or changing it, supports the drive to educate specialists and practitioners in these basic treatment approaches. Overall, the study provides information that reflects common clinical practice and underscores the importance of initiating a strategy to change the pharmacological approach in any patient, at any stage of the treatment of this mental illness.

OBJECTIVES: An unhealthy lifestyle, inappropriate eating habits, and inadequate physical activity are the most common risk factors affecting health and causing the premature onset of non-communicable diseases. The study aimed to evaluate lifestyle factors, eating habits, and daily regimens in a sample of Slovak adolescents. METHODS: The sample involves 524 students aged 15-22 years attending selected secondary schools from the model region of Bratislava, the capital of Slovakia. We assessed the prevalence of selected lifestyle factors and investigated the relationship between negative lifestyle factors and the presence of overweight and obesity. RESULTS: We found eating irregularities including avoidance of school lunch, inadequate daily consumption of vegetables, dairy products and wholegrain foods, and the high consumption of sweets and sweetened beverages. The prevalence of excess weight and obesity in the sample was 18.4%. Compared to the non-obese, overweight or obese students had significantly lower daily consumption of vegetables and used to avoid sports more frequently. Almost 37% of students did not do sports at all. Students who were not doing sports on regular basis used to skip breakfast more frequently, they ate fewer vegetables and more sweets and spent considerable time in sedentary activities. CONCLUSION: In the sample of secondary school students, we investigated several negative lifestyle factors and the relatively high prevalence of overweight and obesity. The results of the study can be used for the development of preventive measures to protect and promote the health of children and youth.

BACKGROUND AND OBJECTIVE: The dual orexin receptor antagonist daridorexant was approved in 2022 for the treatment of insomnia at doses up to 50 mg once per night. This study aimed at investigating the effect of daridorexant 50 mg at steady state on the pharmacokinetics of dabigatran, the active moiety of dabigatran etexilate, and rosuvastatin, sensitive substrates of P-glycoprotein and breast cancer resistance protein, respectively. METHODS: This single-center, open-label, fixed-sequence study enrolled 24 healthy male subjects who were dosed orally with dabigatran etexilate 75 mg on days 1 (Treatment A1) and 9 (Treatment C1) as well as rosuvastatin 10 mg on days 3 (Treatment A2) and 11 (Treatment C2). On days 7-14, daridorexant (50 mg once daily) was administered. Blood samples for the pharmacokinetics of both substrates and the pharmacodynamics of dabigatran, i.e., two coagulation tests, were collected and safety assessments performed. Noncompartmental pharmacokinetic parameters and pharmacodynamic variables were evaluated with geometric mean ratios and 90% confidence intervals of Treatment C1/C2 versus A1/A2. RESULTS: Geometric mean ratios (90% confidence interval) of dabigatran maximum plasma concentration and area under the plasma concentration-time curve were 1.3 (1.0-1.7) and 1.4 (1.1-1.9), respectively, whereas the time to maximum plasma concentration and terminal half-life were comparable between treatments. Pharmacodynamic variables showed a similar pattern as dabigatran pharmacokinetics in both treatments. Rosuvastatin pharmacokinetics were unchanged upon concomitant daridorexant administration. All treatments were well tolerated. CONCLUSIONS: A mild inhibition of P-glycoprotein was observed after administration of daridorexant (50 mg once daily) at steady state, whereas breast cancer resistance protein was not affected. CLINICAL TRIAL REGISTRATION: NCT05480475; date of registration: 29 July, 2022.

IMPORTANCE: Dapagliflozin has been shown to improve overall health status based on aggregate summary scores of the Kansas City Cardiomyopathy Questionnaire (KCCQ) in patients with heart failure (HF) with mildly reduced or preserved ejection fraction enrolled in the Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure (DELIVER) trial. A comprehensive understanding of the responsiveness of individual KCCQ items would allow clinicians to better inform patients on expected changes in daily living with treatment. OBJECTIVE: To examine the association of dapagliflozin treatment with changes in individual components of the KCCQ. DESIGN, SETTING, AND PARTICIPANTS: This is a post hoc exploratory analysis of DELIVER, a randomized double-blind placebo-controlled trial conducted at 353 centers in 20 countries from August 2018 to March 2022. KCCQ was administered at randomization and 1, 4, and 8 months. Scores of individual KCCQ components were scaled from 0 to 100. Eligibility criteria included symptomatic HF with left ventricular ejection fraction greater than 40%, elevated natriuretic peptide levels, and evidence of structural heart disease. Data were analyzed from November 2022 to February 2023. MAIN OUTCOMES AND MEASURES: Changes in the 23 individual KCCQ components at 8 months. INTERVENTIONS: Dapagliflozin, 10 mg, once daily or placebo. RESULTS: Baseline KCCQ data were available for 5795 of 6263 randomized patients (92.5%) (mean [SD] age, 71.5 [9.5] years; 3344 male [57.7%] and 2451 female [42.3%]). Dapagliflozin was associated with larger improvements in almost all KCCQ components at 8 months compared with placebo. The most significant improvements with dapagliflozin were observed in frequency of lower limb edema (difference, 3.2; 95% CI, 1.6-4.8; P < .001), sleep limitation by shortness of breath (difference, 3.0; 95% CI, 1.6-4.4; P < .001), and limitation in desired activities by shortness of breath (difference, 2.8; 95% CI, 1.3-4.3; P < .001). Similar treatment patterns were observed in longitudinal analyses integrating data from months 1, 4, and 8. Higher proportions of patients treated with dapagliflozin experienced improvements, and fewer had deteriorations across most individual components. CONCLUSIONS AND RELEVANCE: In this study of patients with HF with mildly reduced or preserved ejection fraction, dapagliflozin was associated with improvement in a broad range of individual KCCQ components, with the greatest benefits in domains related to symptom frequency and physical limitations. Potential improvements in specific symptoms and activities of daily living might be more readily recognizable and easily communicated to patients.
