ABSTRACT

Where orangethroat darters (Etheostoma: Ceasia) and rainbow darters (Etheostoma caeruleum) co-occur, males prefer conspecific over heterospecific females. The cues males use to identify conspecific females remain unclear. We conducted behavioral trials to ask whether chemical cues function in conspecific recognition. We found that males from three orangethroat darter species preferentially associate with female scent over a control. Our results support the use of olfaction in conspecific identification in the orangethroat clade and contribute to our understanding of signals that may facilitate species recognition and underlie the evolution of behavioral isolation.

ABSTRACT

Objective: To study nomophobia in a large sample of Lebanese adults and its relationship with personality traits and other sociodemographic factors that may contribute to the diagnosis such as sex, parental status, and smoking.Methods: This cross-sectional study was conducted between January and July 2019. A total of 2,260 residents randomly selected from districts in Lebanon completed a questionnaire about sociodemographic characteristic and smoking. Respondents also completed the Nomophobia Questionnaire, Personality Inventory for DSM-5, and NEO Five-Factor Inventory.Results: The results of a linear regression, taking the nomophobia score as the dependent variable, showed that higher neuroticism (B = 0.648), number of waterpipes smoked per week (B = 0.749), and disinhibition (B = 0.706) were significantly associated with higher nomophobia, whereas more agreeableness (B = -0.535) and detachment (B = -0.594) were significantly associated with lower nomophobia.Conclusions: This study assessed the variation of inherent personality traits using 2 validated personality questionnaires and their association with nomophobia. As digital use becomes more prevalent within personal and professional aspects of life, nomophobia might become an anxiety risk. Future studies should focus on preventive and treatment measures in the form of awareness campaigns.

ABSTRACT

BACKGROUND: Previous research revealed an absence of any previous studies reporting the impact that pandemics may have on psychotic symptomology, nor on the physical health of people with psychosis in response to the epidemics of the COVID-19. The direction of the impact of the COVID-19 on schizophrenia is unknown, as the risk of infection could vary from patients to patients according to clinical comorbidities, cognitive impairment, acute symptoms, and family support. To the best of our knowledge, no study has provided details on the variation of symptoms in patients with schizophrenia during the quarantine of COVID-19 outbreak. Therefore, the primary objective of the study is to investigate the variation of psychotic symptoms, depression, obsession and quality of life in patients with schizophrenia before and after 5 months of quarantine and evaluate factors associated with these variations during the quarantine period. METHODS: A cross-sectional study was performed on a sample of 190 chronic patients institutionalized for schizophrenia for more than 1 year at the Psychiatric Hospital of the Cross. The baseline assessment was done in December 2019; the second assessment was done in August 2020 (5 months after the lockdown). RESULTS: Getting updates about the coronavirus minimally, some and most of the times were significantly associated with a decrease in positive psychotic and psychopathologic symptoms 5 months after quarantine compared to before it. Practicing religiosity some and all the time versus not was significantly associated with a decrease in negative, psychopathology symptoms and total PANSS score after 5 months of quarantine compared to before it. Finally, female gender (B = 1.77) was significantly associated with an increase in the WHO Domain 3 score (better social relations) after 5 months of quarantine compared to before it. CONCLUSION: Patients with schizophrenia fare better symptomatically after 5 months of quarantine if they receive constant updates about COVID-19 and if they tended to practice religiosity.

ABSTRACT

BACKGROUND: Agitated patients constitute 10% of all emergency psychiatric treatment. Management guidelines, the preferred treatment of clinicians differ in opinion and practice. In Lebanon, the use of the triple therapy haloperidol plus promethazine plus chlorpromazine (HPC) is frequently used but no studies involving this combination exists. METHOD: A pragmatic randomised open trial (September 2018-July 2019) in the Lebanese Psychiatric Hospital of the Cross in Beirut Lebanon involving 100 people requiring urgent intramuscular sedation due to aggressive behaviour were given intramuscular chlorpromazine 100 mg plus haloperidol 5 mg plus promethazine 25 mg (HPC) or intramuscular haloperidol 5 mg plus promethazine 25 mg. RESULTS: Primary outcome data were available for 94 (94%) people. People allocated to the haloperidol plus promethazine (HP) group showed no clear difference at 20 min compared with patients allocated to the HPC group [relative risk (RR) 0.84, 95% confidence interval (CI) 0.47-1.50]. CONCLUSIONS: Neither intervention consistently impacted the outcome of 'calm', or 'asleep' and had no discernible effect on the use of restraints, use of additional drugs or recurrence. If clinicians are faced with uncertainty on which of the two intervention combinations to use, the simpler HP is much more widely tested and the addition of chlorpromazine adds no clear benefit with a risk of additional adverse effects.

ABSTRACT

OBJECTIVES: Our aim in this study was to identify affective temperament differences utilizing the TEMPS-A in a large sample size of Lebanese patients with schizophrenia and compare them to healthy controls. Gender differences, demographic factors and degree of psychotic symptoms were also considered. A cross-sectional study was conducted at the Psychiatric Hospital of the Cross (PHC) from March to June 2019. Two-hundred fifty chronic patients with schizophrenia were compared to 250 healthy controls randomly chosen from the general population. RESULTS: Patients with schizophrenia significantly had higher mean depressive, cyclothymic, irritable and anxious temperament scores compared to healthy controls. Healthy controls significantly had a higher mean hyperthymic temperament score compared to patients with schizophrenia. In the group of patients with schizophrenia exclusively, females scored higher in terms of depressive, cyclothymic and anxious temperaments compared to males. In the group of healthy controls, males scored higher in terms of hyperthymic and irritable temperaments compared to females, whereas a higher mean depressive and anxious temperament scores were significantly found in females compared to males. In addition, higher PANSS total scores, as well as higher positive, negative and general subscales scores were significantly associated with higher depressive, cyclothymic, irritable and anxious temperament scores.

ABSTRACT

BACKGROUND: International literature clearly describes factors associated with problematic internet use, including substance dependence, online gambling, social impairment, and functional difficulties. Therefore, it was imperative to assess the extent to which young adolescents in Lebanese schools are affected by problematic internet use (PIU) and the factors associated with it. This large-scale Lebanese survey aims to evaluate the relationship between PIU, depression, and substance use, including alcohol consumption and nicotine use (cigarettes and waterpipe) among adolescents in Lebanese schools. METHODS: This cross-sectional study conducted between January and May 2019 assessed internet use through the Internet Addiction Test (IAT), with 'severe internet use' being the threshold for problematic internet use. It enrolled a total of 1810 adolescents aged 14 to 17 from 16 schools from all Lebanese Mohafazat. RESULTS: The majority of the participants had an average internet use 74.8% (95% Confidence Interval (CI): 0.72-0.76), 20.7% (95% CI: 0.18-0.22) had a frequent internet use, and 4.5% (95% CI: 0.03-0.05) had a severe internet use. Higher alcohol dependence (ß = 0.456, p < 0.001), higher depression (ß = 0.079, p = 0.001), and having separated parents vs. living together (ß = 0.136, p < 0.001) were significantly associated with higher IAT scores. Higher waterpipe dependence (ß = -0.218, p < 0.001) was significantly associated with lower IAT scores. CONCLUSION: This study, the first and largest of its kind in the Middle East, showed that some psychiatric disorders, such as depression and substance use (smoking and alcohol), are associated with more problematic internet use among Lebanese adolescents. These results could serve as the first step for policymakers towards implementing early awareness campaigns to look at this problem more in-depth and come up with efficient actions to avoid it.

ABSTRACT

Background: Agitated and aggressive behaviours are common in the psychiatric setting and rapid tranquilisation is sometimes unavoidable. A survey of Lebanese practice has shown that an intramuscular haloperidol, promethazine and chlorpromazine combination is a preferred form of treatment but there are no randomised trials of this triple therapy. Methods: This is a pragmatic randomised trial. Setting - the psychiatric wards of the Psychiatric Hospital of the Cross, Jal Eddib, Lebanon. Participants - any adult patient in the hospital who displays an aggressive episode for whom rapid tranquilisation is unavoidable, who has not been randomised before, for whom there are no known contraindications. Randomisation - stratified (by ward) randomisation and concealed in closed opaque envelope by independent parties. Procedure - if the clinical situation arises requiring rapid tranquilisation, medical residents overseeing the patient will open a TREC-Lebanon envelope in which will be notification of which group of treatments should be preferred [Haloperidol + Promethazine + Chlorpromazine (HPC) or Haloperidol + Promethazine (HP)], along with forms for primary, secondary and serious adverse effects. Treatment is not given blindly. Outcome - primary outcome is calm or tranquil at 20 minutes post intervention. Secondary outcomes are calm/tranquil at 40, 60 and 120 minutes post intervention, asleep, adverse effects, use of straitjacket and leaving the ward. Follow-up will be up to two weeks post randomisation. Discussion: Findings from this study will compare the HPC versus HP combination used in Lebanon's psychiatry emergency routine practice. Trial registration: ClinicalTrials.gov NCT03639558. Registration date, August 21, 2018.

ABSTRACT

Background: Violent patients constitute 10% of all psychiatric admissions. Treatment options and clinical practice interventions vary across the globe and no survey of practice in a Middle Eastern setting exists. Surveying treatments in Lebanon will show treatment interventions used in this part of the world and, most importantly, provide the treatment options that could potentially be used for clinical trials pertaining to emergency psychiatry. Methods: A survey of clinicians' opinions and practice was conducted between July and August 2017 at the largest psychiatric hospital in Lebanon. Results: Five of seven experienced psychiatrists provided opinions when interviewed of their preferred intervention when dealing with an emergency psychiatric episode. Whilst this varied in detail, there was a consistent view that there should first be verbal control, then use of medications, and finally physical restrain of the patient. A total of 39 emergency episodes (28 people) occurred in the one month (64% men in their 30s). Bipolar disorder was the most frequent single diagnosis behind the aggression (n=16, 41%; 12 people 43%) but the combined schizophrenia-like illnesses underlay 18 of the 39 episodes (46%; 13/28 people 46%). In clinical life, we found evidence of high family involvement, but little attempts made at initial verbal control in the hospital. All 39 episodes involved administration of pharmacological interventions. Medications were used in 29 of cases (74%) and non-medication interventions used in the remaining 10/39 (26%). Conclusion: This survey provides some evidence that clinicians' preferences may not fully reflect clinical practice but also that experienced clinicians are using several clearly effective techniques to manage these very difficult situations. However, as for other parts of the world, treatment in Lebanon has limited or no underpinning by evidence from well-designed, conducted and reported evaluative studies.
