The perphenazine and fluphenazine GABA esters 3 and 4 evaluated in rat models for antipsychotic activity displayed a significant decrease of catalepsy associated with increased prolactin blood levels. Efficacy was evaluated in the D-amphetamine-induced hyperactivity model, where perphenazine abolished hyperactivity and induced sedation and catalepsy, whereas 3 reduced hyperactivity without sedation or catalepsy. Thus, 3 (BL-1020) constitutes a prototype of novel antipsychotics possessing GABAergic activity. A phase II study is in progress.

Management of anxiety disorders in children with attention-deficit hyperactivity disorder: a narrative review

Pavel Golubchik, Abraham Weizman

Summary: Anxiety disorders often coexist with ADHD, and treatment options include stimulants, cognitive-behavior therapy, and medication. Stimulant treatment is effective in managing ADHD with comorbid anxiety disorders, but specific treatment for anxiety is also crucial.

COVID-19 pandemic: Impacts on mothers' and infants' mental health during pregnancy and shortly thereafter

Noa Vardi, Gil Zalsman, Nir Madjar, Abraham Weizman, Gal Shoval

Summary: The COVID-19 pandemic has had significant implications on the mental health of mothers and their infants, with maternal stress reactions impacting infant development. Recommendations for enhancing perinatal mental health are discussed based on current research, with suggestions for future studies.

Examining the Use of Antidepressants for Adolescents with Depression/Anxiety Who Regularly Use Cannabis: A Narrative Review

Danielle Hen-Shoval, Aron Weller, Abraham Weizman, Gal Shoval

Summary: Depression and anxiety disorders are common and growing mental health concerns in adolescents, with antidepressant medication use increasing accordingly. Cannabis use may affect the efficacy of antidepressants, particularly among adolescents, highlighting the need for further research in this area.

Complex Effects of Sertraline and Citalopram on In Vitro Murine Breast Cancer Proliferation and on In Vivo Progression and Anxiety Level

Michal Taler, Irit Gil-Ad, Iris Brener, Shay Henry Hornfeld, Abraham Weizman

Summary: This study compared the effects of sertraline and citalopram on breast cancer in mice and found that sertraline can inhibit cell proliferation but promotes tumor growth in vivo. Chronic mild stress does not affect tumor growth.

Clinical and Socio-Demographic Variables Associated with the Diagnosis of Long COVID Syndrome in Youth: A Population-Based Study

Eugene Merzon, Margaret Weiss, Beth Krone, Shira Cohen, Gili Ilani, Shlomo Vinker, Avivit Cohen-Golan, Ilan Green, Ariel Israel, Tzipporah Schneider, Shai Ashkenazi, Abraham Weizman, Iris Manor

Summary: This study examines the factors associated with diagnosis of long COVID syndrome in children. The findings show that children with long COVID syndrome are more likely to have severe symptoms, require hospitalization, and have recurrent acute infections. They are also more likely to have ADHD, chronic urticaria, and allergic rhinitis. The study suggests that clinicians should be vigilant for the possibility of long COVID syndrome in children with pre-existing ADHD. Further research on morbidity related to long COVID syndrome in children is needed.

The Effect of Natural-Based Formulation (NBF) on the Response of RAW264.7 Macrophages to LPS as an In Vitro Model of Inflammation

Sheelu Monga, Basem Fares, Rami Yashaev, Dov Melamed, Meygal Kahana, Fuad Fares, Abraham Weizman, Moshe Gavish

Summary: Macrophages are important immune cells responsible for creating an inflammatory immune response. This study found that a natural-based formulation (NBF) can inhibit the inflammatory response of macrophages and attenuate the release of inflammatory markers. NBF may be a potential candidate for the treatment of inflammatory diseases.

Clozapine Suppresses the Gene Expression and the Production of Cytokines and Up-Regulates Cyclooxygenase 2 mRNA in Human Astroglial Cells

Yael Yuhas, Shai Ashkenazi, Eva Berent, Abraham Weizman

Summary: Schizophrenia is a chronic neurodevelopmental psychotic disorder that involves the immune system and neuroinflammation. Clozapine, an atypical antipsychotic, has been found to have immunomodulatory effects in an astroglial model of neuroinflammation. This study suggests that clozapine can inhibit the production of inflammatory mediators and increase COX2 expression, potentially benefiting patients with treatment-resistant schizophrenia and neuroinflammatory markers.

The Association between Somatotropin Therapy and the Risk of SARS-CoV-2 Infection in Children with Short Stature: A Population-Based Cross-Sectional Study

Summary: This study evaluated the association between growth hormone treatment and the risk of COVID-19 infection in children. The results show that children receiving growth hormone treatment have a lower risk of SARS-CoV-2 positivity, suggesting that growth hormone may act as a protective factor possibly due to its immunomodulatory activity.

Differences in Telomere Length between Adolescent Females with Anorexia Nervosa Restricting Type and Anorexia Nervosa Binge-Purge Type

Summary: The length of telomeres in anorexia nervosa (AN) patients is shorter and does not recover after inpatient treatment. Patients with the restricting type of AN have longer telomeres compared to those with the binge/purge type. Age is the only factor associated with telomere shortening.

Summary: This study found an association between G6PD deficiency and an increased risk of ADHD diagnosis. Individuals with G6PD deficiency were more likely to seek care from adult neurologists and psychiatrists. Moreover, they had a higher usage of stimulant medications.

The Potential Usefulness Of The Social Attribution Task (SAT) in Diagnosing Girls with ASD

Hagit Nagar Shimoni, Yael Leitner, Roni Yoran-Hegesh, Ya'arit Bokek-Cohen, Shahar Gindi, Abraham Weizman

Summary: Clinical observations suggest that girls suspected to have ASD may have better performance in social and emotional tasks than boys, leading to under-diagnosis of girls with ASD. The study found that girls diagnosed with ASD performed better than boys in the Person index of the Social Attribution Task (SAT), indicating that girls with ASD may not have better social understanding than boys, except when prompted to name human traits.

Phenotypic Characterization of Youth Admitted To Acute Psychiatric Inpatient Unit Following Self-Harm Behavior

Maya Schwartz-Lifshitz, David H. Ben-Dor, Yael Bustan, Gil Zalsman, Doron Gothelf, Abraham Weizman, Ran Barzilay

Summary: This retrospective study analyzed the clinical and demographic characteristics of adolescents admitted to an acute psychiatric inpatient unit. The findings showed that adolescents with deliberate self-harm (DSH) were more likely to be female, currently experiencing depressive exacerbation, have concurrent suicidal ideation, and a history of alcohol use. There were no significant clinical differences between adolescents admitted following a suicide attempt and those engaging in non-suicidal self-injury.
