Abstract
Traumatic brain injury (TBI) has the highest mortality rates worldwide, yet effective treatment remains unavailable. TBI causes inflammatory responses, endoplasmic reticulum stress, disruption of the blood-brain barrier and neurodegeneration that lead to loss of cognition, memory and motor skills. Saffron (Crocus sativus L.) is known for its anti-inflammatory and neuroprotective effects, which makes it a potential candidate for TBI treatment. Zebrafish (Danio rerio) shares a high degree of genetic homology and cell signaling pathways with mammals. Its active neuro-regenerative function makes it an excellent model organism for TBI therapeutic drug identification. The objective of this study was to assess the effect of saffron administration to a TBI zebrafish model by investigating behavioral outcomes such as anxiety, fear and memory skills using a series of behavioral tests. Saffron exhibited anxiolytic effect on anxiety-like behaviors, and showed prevention of fear inhibition observed after TBI. It improved learning and enhanced memory performance. These results suggest that saffron could be a novel therapeutic enhancer for neural repair and regeneration of networks post-TBI.

Abstract
OBJECTIVES Estimate the rate of anxiety disorders (AD) and associated factors among patients with substance use disorder (SUD) in Lebanon. METHODS A cross-sectional study, conducted between April and September 2017, enrolled 57 inpatients with SUD. RESULTS The rate of AD in patients with SUD was 61.4%. The university level of education compared to the primary level of education (ORa = 0.221) was significantly associated with lower anxiety among patients with SUD. Being sexually abused and having a family history of depression tended to significance. PRACTICAL IMPLICATIONS AD is widespread in Lebanon and high rates of anxiety in patients with SUD were found, warranting the implementation of strategic interventions and establishing national policies and legislation for mental health services to provide optimal care.

Abstract
OBJECTIVE To assess the prevalence of medical comorbidities in acute manic patients over a period of 1 year, and to evaluate correlates of the readmission rate. DESIGN/METHODS A retrospective observational study was conducted on 158 acute manic patients from 2016 to 2017. RESULTS The most common physical comorbidity was obesity (36.1%) followed by cardiovascular disorders (15.2%) and liver dysfunctions (9.3%). Male gender was associated with higher readmission rate (Beta = -0.260), while taking anticholinergic drugs (Beta = -0.338) and having a family history of psychiatric disorders (Beta = -0.222) were associated with lower readmission rate. PRACTICAL IMPLICATIONS The study results may help physicians and other clinicians understand the burden of illness recurrence in bipolar disorder type I patients and adopt effective strategies to prevent relapse, taking into account all comorbidities.

Abstract
BACKGROUND Neonatal seizures are frequently encountered in the neonatal intensive care unit and may be associated with serious long-term neurological sequelae. Response to treatment continues to be modest, and treatment guidelines remain unclear. The use of levetiracetam has been on the rise in the past several years due to its favorable safety profile in the face of limited data on its efficacy and optimal dosing regimens. Unlike the older age groups, the benefit of escalating to high-dose levetiracetam of 80-100 mg/kg/day in neonates not responding to the standard used dosing regimen (40-60 mg/kg/day) is not studied. We sought to investigate the safety and efficacy of levetiracetam escalation to high dose regimens for neonatal seizures. METHODS A retrospective chart review over a 7-year period was conducted at the American University of Beirut to identify neonates with electrographically proven seizures treated with levetiracetam. Data was collected on electroclinical seizure characteristics, underlying etiology, seizure control, other anti-seizure medications, and adverse effects. RESULTS Electronic chart review revealed a total of 15 neonates with electrographically confirmed seizures treated with levetiracetam, with escalation to high doses in seven. As a first line drug, levetiracetam monotherapy terminated seizures in six out 10 neonates, two of whom had complete seizure cessation only after escalation to high doses of 80 or 100 mg/kg/day. When used in combination with other anti-seizure medications, four out of five neonates achieved complete seizure cessation upon escalation to high doses of levetiracetam. No adverse effects were noted. CONCLUSIONS In neonates not responding to the standard used levetiracetam doses, incremental increases to 80-100 mg/kg/day may be considered. Prospective studies are needed to confirm the promising role of such high dosing regimens, and to better elucidate the role of levetiracetam in neonatal seizures.

Abstract
PURPOSE To examine these temperaments among patients with substance use disorder (SUD) in the Lebanese population. DESIGN Case-control. METHODS Fifty-seven controls and 57 patients with SUD were enrolled between April and September 2017. RESULTS A significantly higher mean of depressive, irritable, and anxious temperaments was found in addicted patients as compared with the nonaddicts. However, the results of the multivariate analysis showed that anxious, hyperthymic, irritable temperaments would significantly increase the odds of addiction in participants (ORa = 25.20, 1.057, 1.168, 1.241, and 1.275). Cyclothymic temperament would significantly decrease the odds of addiction in participants (ORa = 0.817). Furthermore, suicidality was associated with depressive, anxious, and irritable temperaments. PRACTICE IMPLICATIONS Hyperthymic, irritable, and anxious temperaments were the main temperaments found in patients with SUD in Lebanon.

Abstract
Objective: To evaluate the occurrence of cardiovascular (CV), cerebrovascular events and mortality rates, and compare the predictive ability of two scores, Framingham Risk Score (FRS) and Atherosclerotic Cardiovascular Disease (ASCVD), of detecting a cardiovascular event in a cohort of schizophrenic patients. Methods: A cohort of 329 hospitalised schizophrenic patients is being monitored since 1 January 2013. Patients' file review was performed to detect the CV events of interest. Results: Out of the 329 patients with schizophrenia, with a mean study follow-up of 41.07 ± 12.55 months, 29 cardiovascular events were recorded; of those events, we recorded 4 myocardial infarction, 1 stroke, 6 heart failure and 18 cardiovascular deaths. The major composite outcome of cardiovascular events rate was equal to 9.0 per 100 patient-years. The secondary composite outcome of cardiovascular events rate was equal to 7.2 per 100 patient-years (0.072 events per patient). The association between survival curve of patients with high and low CVR according to FRS score tended to significance (RR = 1.90, p = .078). Patients classified as high cardiovascular risk according to ASCVD presented a reduced cardiovascular survival (RR = 3.35, p = .005). Conclusion: The ASCVD items should be included in the medical assessment in any patient with severe mental illness. Key points The major composite outcome of cardiovascular events rate was equal to 9.0 per 100 patient-years. The secondary composite outcome of cardiovascular events rate was equal to 7.2 per 100 patient-years (0.072 events per patient). The association between survival curve of patients with high and low CVR according to FRS score tended to significance. Patients classified as high cardiovascular risk according to ASCVD presented a reduced cardiovascular survival.

Abstract
Aim: The study's objective was to evaluate the relationship between vitamin D (VD) levels and cognitive performance in patients with schizophrenia. Methods: A cross-sectional study, conducted between March and July 2016, recruited 196 patients with schizophrenia. The Brief Cognitive Rating Scale (BCRS) and the Morningside Rehabilitation Status Scale (MRSS) were used to measure the severity of cognitive impairment and the level of general functioning in psychiatric patients. Lower scores for both scales indicate a better cognition and functioning respectively. Vitamin D levels of participants were divided into four groups: severe VD deficiency (<10 ng/ml), VD deficiency (10-20 ng/ml), VD insufficiency (20-30 ng/ml), VD sufficiency (>30 ng/ml). Relationships between VD level and cognition and functioning were assessed by analyses of covariance and hierarchical multiple regression, adjusted for age, gender, marital status, education level, sun exposure, physical activity and monthly income. Results: Severe VD deficiency was found in 22 patients with schizophrenia (11.3%), while 45.6% of patients had VD deficiency. Severe VD deficiency was significantly associated with an increase in MRSS score after adjusting for covariates (Beta = 2.44), however, no significant association was found with the BCRS score. Conclusion: These findings suggest that severe VD deficiency in patients with schizophrenia might be associated with low general functioning but could not influence cognitive function.

Abstract
Bioactive vitamin D is a steroid hormone transported in blood via the vitamin D binding protein (DBP). Our study aimed to investigate the vitamin D status in a young Lebanese population and study the association of hypovitaminosis with levels of DBP. Polymorphisms in the GC gene that encodes DBP were also screened. Blood samples were collected from 179 university students. Vitamin D status and DBP levels were assayed by enzyme-linked immunosorbent assay (ELISA). DNA was extracted from 128 participants, and genotyping of the two GC gene SNPs, rs7041, and rs4588, was carried out by restriction fragment length polymorphism. Forty-seven percent of participants had hypovitaminosis D (<20 ng/ml). A significant positive correlation was observed between vitamin D status and DBP. Genotyping data showed that participants carrying the rs7041 GG and rs4588 AA genotypes had higher concentrations of DBP than those carrying other genotypes. Four allelic versions of the GC gene were observed, one of which, GC*3, was encountered for the first time in this study, and was found to be associated with both normal vitamin D and high DBP levels. Modifying genes such as GC could therefore affect DBP levels, and contribute, along with environmental factors, to the hypovitaminosis D observed in sunny countries.
