Whilst the notion that dreaming mentations reflect distinct physiologic processes is not new, such studies in patients with sleep disorders remain exceptionally scarce. Here, using SGA and other dream content analyses, we set to investigate structural and thematic differences in morning dream recalls of patients diagnosed with Non-Rapid Eye Movement Parasomnia (NREMP) and Idiopathic REM Sleep Behavior Disorder (iRBD).Methods: A retrospective cross-sectional study of morning dream recalls of iRBD and NREMP patients was undertaken. Traditional dream content analyses, such as Orlinsky and Hall and Van de Castle analyses, were initially conducted. Subsequently, SGA was performed in order to objectively quantify structural speech differences between the dream recalls of the two patient groups.Results: Comparable rate of morning recall of dreams in the sleep laboratory was recorded; 25% of iRBD and 18.35% of NREMP patients. Aggression in dreams was recorded by 28.57% iRBD versus 20.00% in NREMP group. iRBD patients were more likely to recall dreams (iRBD vs NREMP; P = 0.007), but they also had more white dreams, ie having a feeling of having dreamt, but with no memory of it. Visual and quantitative graph speech analyses of iRBD dreams suggested stable sequential structure, reflecting the linearity of the chronological narrative. Conversely, NREMP dream reports displayed more recursive, less stable systems, with significantly higher scores of graph connectivity measures.Conclusion: The findings of our exploratory study suggest that iRBD and NREMP patients may not only differ on what is recalled in their dreams but also, perhaps more strikingly, on how dreams are recalled. It is hoped that future SGA-led dream investigations of larger groups of patients will help discern distinct mechanistic underpinnings and any associated clinical implications.Keywords: dreams, speech graph analysis, NREM parasomnia, REM behavior sleep disorder, dream content analysis

Andrea Romigi,1 Giuseppe Vitrani,1 Temistocle Lo Giudice,1 Diego Centonze,1,2 Valentina Franco3 1IRCCS Istituto Neurologico Mediterraneo Neuromed, Pozzilli (IS), Italy; 2Department of System Medicine, University of Rome Tor Vergata Rome, Italy; 3IRCCS Mondino Foundation, Pavia, Italy Abstract: Narcolepsy is a rare sleep disorder characterized by excessive daytime sleepiness and rapid eye movement sleep dysregulation, manifesting as cataplexy and sleep paralysis, as well as hypnagogic and hypnopompic hallucinations. Disease onset may occur at any age, although adolescents and young adults are mainly affected. Currently, the diagnosis delay ranges from 8 to 10 years and drug therapy may only attenuate symptoms. Pitolisant is a first-in-class new drug currently authorized by the European Medicines Agency to treat narcolepsy with or without cataplexy in adults and with an expanded evaluation for the treatment of neurologic diseases such as Parkinson’s disease and epilepsy. This article reviews the pharmacokinetic and pharmacodynamic profile of pitolisant, highlighting its effectiveness and safety in patients with narcolepsy. We performed a systematic review of the literature using PubMed, Embase, and Google Scholar. We report on the efficacy and safety data of pitolisant in narcoleptic patients regarding cataplexy episodes and subjective and objective daytime sleepiness. The development program of pitolisant was characterized by eight Phase II/III studies. One proof-of-concept study followed by two pivotal studies, three randomized controlled trials, and two open studies were evaluated. Our review confirmed the effectiveness of pitolisant in treating major clinically relevant narcolepsy symptoms, including cataplexy, as compared to placebo. In addition, pitolisant revealed a safe profile when compared with placebo and active comparators. Headache, insomnia, and nausea were the prominent side effects. Further long-term randomized controlled trials comparing the efficacy of pitolisant with active comparators (ie, modafinil and sodium oxybate) may clarify its real place in therapy and its possible use as a first-line agent on the basis of its safety and tolerability.

Andrea Romigi,1,2 Eti A Femia,3 Cinzia Fattore,4 Giuseppe Vitrani,1 Giancarlo Di Gennaro,1 Valentina Franco4 1Istituto Neurologico Mediterraneo, IRCCS Neuromed, Pozzilli (IS), Italy; 2Neurophysiopathology Department, University of Rome Tor Vergata, Rome, Italy; 3Dipartimento di Scienze della Salute, Università degli Studi di Milano, Milano, Italy; 4Clinical Trial Centre & Antiepileptic Drugs, C. Mondino National Neurological Institute, Pavia, Italy Abstract: Zonisamide (ZNS), a second-generation antiepileptic drug, indicated as add-on treatment of focal epilepsy, has been recently approved as monotherapy for the treatment of partial seizures in adults affected by newly diagnosed epilepsy in Europe. Evidence on the efficacy and tolerability of antiepileptic drugs in the elderly is still lacking as these patients are frequently excluded from clinical trials. Here, a comprehensive overview of available data regarding the use of ZNS in the treatment of epilepsy in elderly people is provided. In a pooled analysis conducted in patients aged ≥65 years, no new/unexpected safety findings have emerged. Few data from uncontrolled investigations suggest that ZNS may be effective and well tolerated when administered as monotherapy or adjunctive antiepileptic treatment in the elderly. However, evidence from these observational studies is less than satisfactory, and randomized controlled trials focused on these patients are still needed. Keywords: zonisamide, elderly, epilepsy, safety, efficacy

Introduction: Despite nurses representing the largest healthcare professional group, the number is not enough for global health coverage. Understanding Generation Z students' intrinsic and extrinsic motivations, internal and external influences, and beliefs in choosing nursing education is crucial. This knowledge empowers universities to enhance nursing program enrollment through targeted promotion and recruitment strategies. Objective: The aim was to understand why Italian students of Generation Z choose the Nursing Degree Course. Methods: In this pilot study, a cross-sectional design was used. A survey with closed and open answers analyzing demographics, opinions, and motivations among new enrolled nursing students was administered on the first day of the Bachelor of Nursing Degree course. Descriptive statistics were used. Quantitative data were analyzed with Chi-square and ANOVA tests and qualitative data underwent content analysis and coding. Correlation analysis explored relationships between qualitative and quantitative results. Results: Forty first-year students (85% female, average age 22) completed the questionnaire. The choice of the degree pathway, as the first or second option, is influenced by intrinsic and extrinsic motivations, the student's opinions, and family and social influences. Significant positive and negative associations were evidenced. Negative factors affecting choice included location and the responsibility for nursing care, while positive factors included role models, family advice, passion, curiosity for healthcare, the desire to help others, and family influences on decision-making. Conclusions: Among Italian generation Z students, the choice of the nursing degree pathway is influenced by social models, family advice, passion, the desire to help others, and curiosity. Universities should be more proactive in their recruitment and promotion efforts, transforming these events into vibrant meeting points for professionals from diverse nursing specialties. They should also implement robust information policies that highlight career possibilities spanning clinical practice, management, education, and research areas within the field.

Study Objectives: The aim of this cross-sectional study is to explore the association between serum 25-hydroxyvitamin D [25(OH)D] levels, a marker of Vitamin D status, and excessive daytime sleepiness (EDS), expressed as increased scores of the Epworth Sleepiness Scale (ESS), in a group of prospectively enrolled patients with obstructive sleep apnea (OSA). Methods: Newly diagnosed patients with OSA, divided into two groups, those with EDS (ESS > 10) and those without EDS (ESS < 10). All patients underwent night polysomnography. Measurement of serum 25(OH)D vitamin was performed using a radioimmunoassay. Results: In total, 217 patients with OSA (197 males and 20 females) were included. Patients with EDS had higher AHI (p < 0.001) values and lower mean serum 25(OH)D levels, compared with those of non-somnolent patients [17.4 (12.2–25.7) versus 21.1 (15.3–28.8) ng/mL, respectively, p = 0.005]. In patients with EDS, serum 25(OH)D levels correlated with average oxyhemoglobin saturation during sleep (r = 0.194, p = 0.043), and negatively with ESS score (r = −0.285, p = 0.003), AHΙ (r = −0.197, p = 0.040) and arousal index (r = −0.256, p = 0.019). Binary regression analysis identified Vit D serum levels (β = −0.045, OR: 0.956, 95% CI: 0.916–0.997, p = 0.035), total sleep time (β = 0.011, OR: 1.011, 95% CI: 1.002–1.021, p = 0.016) and AHI (β = 0.022, OR: 1.022, 95% CI: 1.003–1.043, p = 0.026) as independent predictors of EDS in patients with OSA. In patients with EDS, multiple regression analysis indicated that ESS score was negatively associated with Vit D serum levels (β = −0.135, p = 0.014) and minimum oxyhemoglobin saturation during sleep (β = −0.137, p = 0.043). Conclusions: In the present study, EDS in patients with OSA is associated with low levels of Vitamin D, while sleep hypoxia may play a role in this process. [ABSTRACT FROM AUTHOR]

Objective: To investigate changes in depressive and suicidality status and their relationship with seizure outcomes after the addition or substitution of another antiseizure medication (ASM) in adults with drug‐resistant focal epilepsy. Methods: Seven hundred seventy consecutively enrolled patients were assessed and followed prospectively for seizure outcome and depressive status over a 6‐month period after starting treatment with a newly introduced ASM. The Neurological Disorders Depression Inventory for Epilepsy (NDDIE) was used to screen for depression and suicidality. Correlations of NDDIE results with clinical and treatment‐related variables were assessed by using a stepwise logistic regression model. Results: At baseline, 50% of patients had a positive screening test result for depression and 13% had a positive screening test result for suicidal ideation. A psychiatric comorbidity at baseline was associated with a 2.3 times increased risk of an initially negative NDDIE screening result becoming positive at re‐assessment after 6 months. In addition, the number of ASMs taken at baseline correlated with an increased risk of a change in depression screening test results from negative to positive during follow‐up, whereas no association was identified with sociodemographic and epilepsy‐related variables, including seizure outcomes. Approximately 6% of patients who were initially negative at screening for suicidal ideation became positive at the 6‐month re‐assessment. The risk of switch from a negative to a positive screening test result for suicidal ideation was increased more than two‐fold in individuals who screened positive for depression at baseline, and was unrelated to the type of ASM introduced, sociodemographic variables, or seizure outcomes. Significance: Almost 1 in 5 adults with drug‐resistant focal epilepsy who screen negative for depression become positive when re‐assessed 6 months after a treatment change. At re‐assessment 6 months later, 6.1% who screen initially negative for passive suicidal ideation become positive. These changes in screening status are independent of type of ASM introduced or seizure outcomes but correlate with psychiatric status at baseline. [ABSTRACT FROM AUTHOR]
