Stress and anxiety

The present study aimed to report the prevalence of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) in the general adult Hong Kong population, and examine the validity of the Chinese International Trauma Questionnaire (ITQ). This descriptive cross-sectional population-based telephone survey included a representative sample of 1070 non-institutionalized permanent Hong Kong residents ages 18-64 years. Participants provided responses to the Chinese version of the ITQ, and measures of adverse childhood experiences (ACEs), depression, anxiety, and stress...

Parental factors play a major role in youth mental health and many youth in high-income countries have at least one overseas-born parent. It is, hence, important to understand how immigrant parenting is associated with youth mental health in high-income countries. Following PRISMA guidelines, this review sought to identify modifiable parental factors to inform parenting interventions to prevent mental health problems in youth aged 0-18 years whose parents migrated voluntarily for economic reasons from low and middle-income countries to high-income countries...

Central fatigue is a common pathological state characterized by psychological loss of drive, lack of appetite, drowsiness, and decreased psychic alertness. The mechanism underlying central fatigue is still unclear, and there is no widely accepted successful animal model that fully represents human characteristics. We aimed to construct a more clinically relevant and comprehensive animal model of central fatigue. In this study, we utilized the Modified Multiple Platform Method (MMPM) combined with alternate-day fasting (ADF) to create the animal model...

Elevated anxiety often precedes anorexia nervosa and persists after weight restoration. Patients with anorexia nervosa often describe self-starvation as pleasant, potentially because food restriction can be anxiolytic. Here, we tested whether repeated stress can cause animals to prefer a starvation-like state. We developed a virtual reality place preference paradigm in which head-fixed mice can voluntarily seek a starvation-like state induced by optogenetic stimulation of hypothalamic agouti-related peptide (AgRP) neurons...

BACKGROUND: Prenatal maternal distress can negatively affect pregnancy outcomes, yet its impact on the offspring's brain structure and function remains unclear. This systematic review summarizes the available literature on the relationship between prenatal maternal distress and brain development in fetuses and infants up to 12 months of age. METHODS: We searched Central, Embase, MEDLINE, PsycINFO, and PSYNDEXplus for studies published between database inception and December 2023...

PURPOSE: Chronic psychological stress develops and exacerbates irritable bowel syndrome (IBS). 5-hydroxytryptamine (5-HT) via activation of intestinal 5-HT3 receptors involves impairment of intestinal functions. This study aimed to investigate the effects of ondansetron, a 5-HT3 receptor antagonist, on locomotor activity, anxiety-related behaviors, and colonic functions in repeated water avoidance stress. MATERIALS AND METHODS: Food intake and fecal pellet output (FPO) of sham stress (SS), water avoidance stress (WS), and water avoidance stress with oral administration of ondansetron (1 mg/kg BW) (WA) groups were monitored along the water avoidance stress protocol for 10 consecutive days...

This study aimed to explore the predictors of posttraumatic stress disorder (PTSD) in women who have recently experienced sexual assault, by examining psychological and neurophysiological factors using a prospective design with resting-state electroencephalogram (EEG) functional connectivity. The study enrolled 33 women who had been recently traumatized by sexual assault and conducted assessments within a month of the trauma. These survivors were evaluated for PTSD three months later and were classified into two groups: PTSD positive (n = 12) and PTSD negative (n = 21)...

The study's significance lies in the multitude of challenges facing individuals today, such as the COVID-19 pandemic, military conflicts like the war in Ukraine, and the escalating rates of cancer morbidity and mortality. These factors contribute to the onset of anxiety and depressive disorders, disrupting various aspects of individuals' mental functioning and social interactions. Addressing these disorders effectively necessitates a comprehensive approach, combining pharmacological interventions with psychotherapeutic strategies under the guidance of specialized professionals...

Health care workers are at increased risk for mental health issues due to high psychological and physical job demands. According to a recent study, stress beliefs (i.e., believing stress to be detrimental to one's health) might influence physicians' mental health in response to a naturalistic stressor (COVID-19 hospital working conditions). Due to a small sample size and high alpha error inflation, the suggested association needs to be interpreted with caution. The current study aims to replicate those findings in a larger sample...

In clinical practice, depression and anxiety frequently coexist, and they are both comorbid with somatic diseases. The P2X7R is an adenosine 5'-triphosphate (ATP)-gated non-selective cation channel that is widely expressed in immune-related cells. Under conditions of stress, chronic pain, and comorbid chronic physical illness, P2X7R activation in glial cells leads to neuroinflammation. This could contribute to the development of anxiety and depression-related emotional disturbances. Previous studies have shown that the P2X7 receptor (P2X7R) plays an important role in the pathogenesis of both anxiety and depression...

OBJECTIVE: This study aimed to understand the key determinants for poor academic performance of students completing a Bachelor of Pharmacy (BPharm), Bachelor of Pharmacy and Management (BPharmMgmt), or Master of Pharmacy (MPharm) degree. METHODS: Data were collected on pharmacy students who had not met academic progression requirements between 2008 and 2018 at The University of Sydney, Australia. This included: age at the start of pharmacy degree; gender; whether they transferred from another university; whether they were a domestic or international student; Australian Tertiary Admissions Rank upon entry, previous studies in biology, chemistry, or mathematics; show cause triggers (units of study failed); number of show causes; students' written show cause responses; weighted average mark at last show cause or graduation; whether they graduated and were a registered pharmacist; and, the number of years they spent studying the degree...

BACKGROUND: Sexual minorities have higher rates of anxiety, depression, and binge eating compared to heterosexual peers. Internalized weight bias (IWB) is also higher for sexual minorities when compared to heterosexual peers. However, research has not examined whether the relationships between IWB and anxiety, depression, and binge eating differ among heterosexual and sexual minority adults pursuing bariatric surgery. OBJECTIVES: To examine whether sexual orientation (heterosexual or sexual minority) moderated the relationships between IWB and anxiety, depression, and binge eating among adults pursuing bariatric surgery...

OBJECTIVE: Few studies have explored the mental health status of parents of children with burns and the moderating effect of social support on them. METHODS: A survey was performed with parents of 112 burn-injured children at a burn center in China. Their perceived stress, anxiety, depression, sleep quality, and social support were measured by the Chinese Perceived Stress Scale, Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, and Perceived Social Support Scale...

BACKGROUND: Post-traumatic stress disorder (PTSD) refers to a chronic impairing psychiatric disorder occurring after exposure to the severe traumatic event. Studies have demonstrated that medicinal cannabis oil plays an important role in neuroprotection, but the mechanism by which it exerts anti-PTSD effects remains unclear. METHODS: The chronic complex stress (CCS) simulating the conditions of long voyage stress for 4 weeks was used to establish the PTSD mice model...

First responders and other public safety personnel (PSP) experience high rates of mental health problems and face barriers to accessing mental healthcare. Internet-delivered cognitive behavioural therapy (ICBT) is an effective and accessible treatment for various mental health concerns. Canadian PSP report favorable attitudes toward ICBT, and preliminary outcomes demonstrate that they benefit from it. Expanding on this research, the current study consisted of a longitudinal observational study of 560 Canadian PSP who participated in ICBT...

METHODS: A multicentre cross-sectional study was conducted, 538 women with breast cancer were recruited from four hospitals. FT, family resilience, and negative emotions were collected using the Comprehensive Score for FT, the Chinese version of the Family Resilience Assessment in Breast Cancer Patients, Patient Health Questionnaire-9 item, and Generalized Anxiety Disorder-7...

BACKGROUND: The impact that the COVID-19 pandemic has had on health care workers' mental health, in particular, cannot be ignored. Not only did the pandemic exacerbate mental health challenges through elevated stress, anxiety, risk of infection, and social isolation, but regulations to minimize infection additionally hindered the conduct of traditional in-person mental health care. OBJECTIVE: This study explores the feasibility of using Wysa, an artificial intelligence-led mental health app, among health care workers...

Nursing students increasingly report being stressed. As a potential treatment, students are using marijuana, according to nursing schools. Currently, there is no standardized guideline for the use of marijuana or marijuana testing for nursing students. This article discusses several concerns about clinical nursing students' use of marijuana for stress and anxiety relief.

BACKGROUND: There is a need to develop and coordinate dementia care plans that use assistive technology for vulnerable groups such as immigrant populations. However, immigrant populations are seldom included in various stages of the development and implementation of assistive technology, which does not optimize technology acceptance. OBJECTIVE: This study aims to gain an in-depth understanding of the acceptance of a digital personal assistant, called Anne4Care, by older adult immigrants living with dementia in their own homes...

Pain, a comorbidity of anxiety disorders, causes substantial clinical, social, and economic burdens. Emerging evidence suggests that propofol, the most commonly used general anesthetic, may regulate psychological disorders; however, its role in pain-associated anxiety is not yet described. This study investigates the therapeutic potential of a single dose of propofol (100 mg kg-1 ) in alleviating pain-associated anxiety and examines the underlying neural mechanisms. In acute and chronic pain models, propofol decreased anxiety-like behaviors in the elevated plus maze (EPM) and open field (OF) tests...
