Education and socioeconomic status as predictors of refugee mental health: insights from a study of Jordan-based Syrian refugee sample.

Background: The Syrian civil war is considered as the greatest humanitarian crisis in modern history, which has resulted in a major refugee crisis. A significant concern is the high prevalence of mental disorders such as depression, anxiety, and post-traumatic stress disorder (PTSD) among Syrian refugees. While the focus of most refugee mental health research has been pre-migration trauma, post-migration challenges and stressors, which can also be significant determinants of mental health, are often ignored.

Autoimmune and neuropsychiatric phenotypes in a transgenic mouse model on C57BL/6 background.

Introduction: Systemic Lupus Erythematosus (SLE) impacts the central nervous system (CNS), leading to severe neurological and psychiatric manifestations known as neuropsychiatric lupus (NPSLE). The complexity and heterogeneity of clinical presentations of NPSLE impede direct investigation of disease etiology in patients. The limitations of existing mouse models developed for NPSLE obstruct a comprehensive understanding of this disease.

Acceptance of COVID-19 vaccination in a sample of Middle Eastern and North African (MENA) Houston residents.

Background: COVID-19 vaccination has averted a significant number of deaths in the United States, but vaccination hesitancy continues to be a problem. Therefore, examining vaccination acceptance and/or hesitancy in local communities is critical.

Methods: A quantitative survey and a multivariable logistic regression model was utilized to determine predictors of COVID-19 vaccination in Middle Eastern and North African (MENA) origin Houston residents.

Breast Cancer Beliefs and Screening Practices among Syrian Refugee Women and Jordanian Women.

Despite significant declines in breast cancer (BC) incidence in the West, this disease is widespread in Jordan, where cancer detection occurs at much advanced stages. This is particularly concerning for Syrian refugee women resettled in Jordan, who are less likely to undergo cancer preventative procedures because of poor health literacy and lack of health services access. The present work assesses and compares breast cancer awareness and breast cancer screening behaviors among Syrian refugee women and Jordanian women residing close to the Syrian-Jordanian border city of .

Understanding Mental Health Status of Syrian Refugee and Jordanian Women: Novel Insights from a Comparative Study.

(1) Background: War and displacement are well-known predictors of negative mental health outcomes among affected populations. This is especially relevant for refugees of war, particularly women, who often repress their mental health needs due to family responsibilities, social stigma, and/or cultural pressures. In this study, we compared the mental health status of urban Syrian refugee women ( = 139) with local Jordanian women ( = 160).

Early Life Sleep Deprivation and Brain Development: Insights From Human and Animal Studies.

Adequate sleep especially during developmental stages of life, is considered essential for normal brain development and believed to play an important role in promoting healthy cognitive and psychosocial development, while persistent sleep disturbances and/or sleep deprivation during early life are believed to trigger many mental ailments such as anxiety disorders, depression, and cognitive impairment. Initially it was suggested that adverse mental health conditions adversely affect sleep, however, it is now accepted that this association is bidirectional. In fact, sleep disturbances are listed as a symptom of many mental health disorders.

Early-Life Sleep Deprivation Enhanced Alcohol Consumption in Adolescent Rats.

Evidence in the literature suggests that sleep deprivation during early-life developmental stages, by impacting important processes such as the reward circuit maturation, may increase the vulnerability for alcohol and substance use. The mechanisms involved are not fully understood. In this study, utilizing our previously established model, we examined the impact of early-life sleep deprivation on alcohol consumption in adolescent rats.

Displacement and Isolation: Insights from a Mental Stress Survey of Syrian Refugees in Houston, Texas, USA.

(1) Background: Syrians are the largest forcibly displaced population in the world. Approximately 20,000 Syrian refugees have resettled in the United States (US) since the civil war in Syria began in 2011, with an estimated 130 families resettling in Houston, Texas. We conducted a pilot study with the objective of examining the physical and mental well-being of the Houston Syrian refugee population.

Perception Regarding Knowledge of COVID-19 Prevention in a Sample of a Middle Eastern and North African (MENA) Community in Houston, Texas, USA.

(1) Background: Knowledge of COVID-19 prevention among communities is the first step towards protective behaviors. The objective of this study was to assess COVID-19 prevention knowledge among a Middle Eastern and North African community in Houston, Texas. (2) Methods: A cross-sectional study was conducted using a validated quantitative survey; survey questions consisted of three parts: COVID-19 specific questions, general health questions, and sociodemographic questions.

Understanding stress: Insights from rodent models.

Through incorporating both physical and psychological forms of stressors, a variety of rodent models have provided important insights into the understanding of stress physiology. Rodent models also have provided significant information with regards to the mechanistic basis of the pathophysiology of stress-related disorders such as anxiety disorders, depressive illnesses, cognitive impairment and post-traumatic stress disorder. Additionally, rodent models of stress have served as valuable tools in the area of drug screening and drug development for treatment of stress-induced conditions.

The coping strategies followed by university students to mitigate the COVID-19 quarantine psychological impact.

Unlabelled: Different strategies were followed to control the spread of the COVID-19 disease worldwide. Jordan declared a military-enforced curfew for three months, which successfully controlled the disease spreading. However, the curfew impacted several aspects of students' lives and personalities.

Simulated vehicle exhaust exposure induces sex-dependent behavioral deficits in rats.

Chronic exposure to vehicle exhaust emissions are known to cause several adverse health effects. In this study, we examined the impact of several parameters of behavioral, cardiovascular and biochemical functions upon exposure of pro-oxidants CO, NO and CO (simulated vehicle exhaust exposure: SVEE) in male and female rats. Adult rats were subjected to SVEE or ambient air in whole body chambers (5 h/day, 2 weeks).

The Influence of Coronavirus Diseases 2019 (COVID-19) Pandemic and the Quarantine Practices on University Students' Beliefs About the Online Learning Experience in Jordan.

Coronavirus Disease 2019 (COVID-19) is a contagious disease that affects the respiratory system. In addition to the severe effects of the disease on health, the pandemic caused a negative impact on basic needs and services, employment, education, and economy worldwide. In Jordan, the whole country locked down, and quarantine was enforced by the military forces, which successfully controlled the spread of the disease.

Protective effect of propranolol and nadolol on social defeat-induced behavioral impairments in rats.

Benzodiazepines and SSRIs are considered as standard treatment options for anxiety and depression, hallmarks of Post-Traumatic Stress Disorder (PTSD), although their use is often limited by adverse effects. While promising evidence emerged with β-adrenergic receptor (β-AR) antagonists (or 'β-blockers') and PTSD relief, efficacy issues dampened the excitement. However, we believe it is premature to completely eliminate a beneficial role of β-blockers.

Sleep deprivation, oxidative stress and inflammation.

Adequate sleep is essential for normal brain function, especially during early life developmental stages as postnatal brain maturation occurs during the critical period of childhood and adolescence. Therefore, sleep disturbance and/or deficit during this period can have detrimental consequences. Many epidemiological and clinical studies have linked early life sleep disturbance with occurrence of later life behavioral and cognitive impairments.

Stress, psychiatric disorders, molecular targets, and more.

Mental health is central to normal health outcomes. A widely accepted theory is that chronic persistent stress during adulthood as well as during early life triggers onset of neuropsychiatric ailments. However, questions related to how that occurs, and why are some individuals resistant to stress while others are not, remain unanswered.

Early Life Sleep Deprivation: Role of Oxido-Inflammatory Processes.

The adverse consequences of early-life sleep deprivation on mental health are well recognized, yet many aspects remain unknown, therefore, animal studies can offer useful insights. Male Sprague-Dawley rats at postnatal day (PND) 19 were subjected to sleep deprivation (SD) for 14 days (6-8 hours/day). Control (CON) rats were gently handled.

Behavioral and cognitive impact of early life stress: Insights from an animal model.

Background: Children subjected to traumatic events during childhood are reported to exhibit behavioral and cognitive deficits later in life, often leading to post-traumatic stress disorder (PTSD) and major depression. Interestingly, some children continue to remain normal despite being exposed to the same risk factors. These trauma-related behavioral and cognitive profiles across different stages of life are not well understood.

Prior treadmill exercise promotes resilience to vicarious trauma in rats.

Background: Post-traumatic stress disorder (PTSD) is a serious psychological condition, which can develop both from physically experiencing and also from witnessing traumatic events. There is evidence that physical exercise can have a positive impact on the symptoms of PTSD. Relevant to this, in our previous pre-clinical work, beneficial effects of treadmill exercise were reported on PTSD-like behaviors in a social defeat paradigm, a rat model of direct physical trauma.

Tempol protects sleep-deprivation induced behavioral deficits in aggressive male Long-Evans rats.

Earlier, we reported that elevated anxiety-like behavior and high aggression in aged retired breeder Long-Evans (L-E) rats was associated with increased plasma corticosterone and elevated oxidative stress levels. In the present study, we examined how this aged aggressive and anxious rat strain responds to acute sleep deprivation (24h) and whether their behaviors can be modulated via antioxidant tempol treatment. Four groups of L-E rats were utilized: naïve control (NC), tempol treated control (T+NC), sleep deprived (SD), tempol treated and sleep deprived (T+SD).

Tempol treatment reduces anxiety-like behaviors induced by multiple anxiogenic drugs in rats.

We have published that pharmacological induction of oxidative stress (OS) causes anxiety-like behavior in rats. Using animal models, we also have established that psychological stress induces OS and leads to anxiety-like behaviors. All evidence points towards the causal role of OS in anxiety-like behaviors.

Grape powder prevents cognitive, behavioral, and biochemical impairments in a rat model of posttraumatic stress disorder.

Previously, using the single-prolonged stress (SPS) rat model of posttraumatic stress disorder, we reported that moderate treadmill exercise, via modulation of oxidative stress-related mechanisms, rescued anxiety- and depression-like behaviors and reversed SPS-induced memory impairment. In this study using the SPS model (2-hour restrain, 20-minute forced swimming, 15-minute rest, and 1-2-minute diethyl ether exposure), we hypothesized that antioxidant rich grape powder (GP) prevents SPS-induced behavioral and memory impairment in rats. Male Sprague Dawley rats were randomly assigned into control (CON) (provided tap water), SPS (provided tap water), GP-SPS (provided 15 g/L GP in tap water for 3 weeks followed by SPS), or GP-CON (3 weeks of GP followed by CON exposure).

High aggression in rats is associated with elevated stress, anxiety-like behavior, and altered catecholamine content in the brain.

The social defeat paradigm involves aggressive encounters between Long-Evans (L-E) (resident) and Sprague-Dawley (S-D) (intruder) rats. Successful application of chronic social defeat stress in S-D rats is dependent upon selection of highly aggressive L-E rats. Half of the L-E rats screened for aggression did not meet the criterion for aggression (L-E rats performing a defeat, characterized by the intruder surrendering or acquiring a supine position for at least 3s).

Novel mechanistic insights into treadmill exercise based rescue of social defeat-induced anxiety-like behavior and memory impairment in rats.

Social defeat (SD) induced stress causes physiological and behavioral deficits in rodents, including depression and anxiety-like behaviors, as well as memory impairment. Anxiolytic and mood elevating effects of physical exercise are also known. However, rescue effect of physical exercise in social defeat-induced anxiety, depression or memory impairment has not been addressed.
