Peripheral artery disease (PAD) is associated with poor health status (symptoms, functioning, quality of life (QOL)). Whether sex differences exist in PAD-specific health status is unknown. In patients presenting to a specialty clinic with new-onset or recent exacerbation of PAD, we examined sex differences as assessed by the Peripheral Artery Questionnaire (PAQ). The Patient-centered Outcomes Related to TReatment Practices in Peripheral Arterial Disease: Investigating Trajectories (PORTRAIT) study is a multicenter, international prospective study of patients with new or worsening PAD symptoms...

PURPOSE OF REVIEW: Recent literature focused on prescription opioids has neglected sex differences in use. Here, we evaluated the recent literature (since 2015) examining sex differences in prescription opioid use. RECENT FINDINGS: Between 2015 and 2016, our review found only eight articles addressing sex differences in prescription opioid use mostly opioid misuse in North America among individuals with chronic pain. Risk factors included depression, pain, and polydrug use...

Maternal stress during pregnancy has been linked to premorbid abnormalities associated with depression (e.g., difficult temperament, cognitive deficits) in offspring. However, few studies have looked across developmental periods to examine maternal stress during pregnancy and offspring depression during adolescence and whether these associations differ by sex. The current study used data from 1711 mother-offspring dyads (offspring sex: 49.8% male) in a longitudinal birth cohort study. Maternal narratives collected during pregnancy were qualitatively coded for stress-related themes by independent raters...

BACKGROUND: Although there is an interconnection between history of major depressive disorder (HMDD) and smoking, there has been relatively limited scientific attention oriented on the interplay between HMDD and smoking maintenance processes. AIM: The current study sought to address whether HMDD and post-cessation craving interact in the prediction of relapse among treatment-seeking smokers. Separate models were evaluated as a function of sex. METHODS: Participants (N = 319, Mage = 41...

The influence of sex on prevalence and presentation of human depression necessitates studying its role in depression. Additionally, stress can also affect the incidence and progression of depressive phenotypes. Hypothalamus is a well-reported sexually dimorphic brain region. Hence, we performed a gene-array to uncover the chronic stress-induced transcriptional changes in the hypothalamus of male, intact female (with ovaries) and ovariectomized female mice. Chronic variable mild stress model was used to induce depression-like behavior in mice, assessed by despair behavior in forced swim test...

We have reported that none of the psychological/mental variables examined predicted the increase in BMI and non-communicable diseases (NCDs) in Iraqi refugees after 1 year resettlement in Michigan. We continuously followed the same cohort of refugees for 2 years (Y2 FU) to further determine the gender difference in predicting of increased BMI and NCDs. Only 20% of the BMI variability could be accounted for by the factors examined. Number of dependent children and depression were positively and stress negatively associated with BMI in male refugees but not in females...

Depression and anxiety are the most common psychiatric disorders, representing a major public health concern. Dysregulation of oxidative and inflammatory systems may be associated with psychiatric disorders, such as depression and anxiety. Due to the need to find appropriate animal models to the understanding of such disorders, we queried whether 2 BXD recombinant inbred (RI) mice strains (BXD21/TyJ RI and BXD84/RwwJ RI mice) and C57BL/6 wild-type mice show differential performance in depression and anxiety related behaviors and biomarkers...

Men and women manifest different symptoms of depression and under current diagnostic criteria, depression is twice as prevalent in woman. However, little is known of the mechanisms contributing to these important sex differences. Sub-chronic variable stress (SCVS), a rodent model of depression, induces depression-like behaviors in female mice only, modeling clinical evidence of higher susceptibility to mood disorders in women. Accumulating evidence indicates that altered neuroplasticity of excitatory synapses in the nucleus accumbens (NAc) is a key pathophysiological feature of susceptibility to social stress in males...

BACKGROUND: A variety of neurological disorders, including Alzheimer's disease, Parkinson's disease, major depressive disorder, dyslexia and autism, are differentially prevalent between females and males. To better understand the possible molecular basis for the sex-biased nature of neurological disorders, we used a developmental series of female and male mice at 1, 2, and 4 months of age to assess both mRNA and protein in the hippocampus with RNA-sequencing and mass-spectrometry, respectively...

Few studies have examined relationships between circadian rhythms and unipolar major depressive disorder. Further, no study to date has examined circadian markers as predictors of response to depression treatment. In the present study, we examined associations between circadian timing and its alignment with sleep and depression severity in 30 adults with major depressive disorder who completed a randomized controlled trial of two weeks of time in bed (TIB) restriction administered adjunctive to fluoxetine, with a focus on sex differences...

Putamen volume is seen to alter in neurological and psychiatric disorders like Parkinson's disease, depression, schizophrenia, Alzheimer's disease, and in individuals treated with antipsychotics. To establish a trend in volume changes in pathologic states, studies on factors influencing normal variation in a given population become essential. This study aimed to evaluate the normal variations in putamen volume in the Indian population and correlate them with the effects of age and sex. Bilateral symmetry was also evaluated...

The prevalence of some mental illnesses, including major depression, anxiety-, trauma-, and stress-related disorders, some substance use disorders, and later onset of schizophrenia, is higher in women than men. While the higher prevalence in women could simply be explained by socioeconomic determinants, such as income, social status, or cultural background, extensive studies show sex differences in biological, pharmacokinetic, and pharmacological factors contribute to females' vulnerability to these mental illnesses...

BACKGROUND: Dr. Athina Markou sought treatments for a common neural substrate shared by depression and drug dependence. Antagonists of corticotropin-releasing factor (CRF) receptors, a target of interest to her, have not reached the clinic despite strong preclinical rationale and sustained translational efforts. METHODS: We explore potential causes for the failure of CRF1 antagonists and review recent findings concerning CRF-CRF1 systems in psychopathology. RESULTS: Potential causes for negative outcomes include (1) poor safety and efficacy of initial drug candidates due to bad pharmacokinetic and physicochemical properties, (2) specificity problems with preclinical screens, (3) the acute nature of screens vs...

BACKGROUND AND PURPOSE: Clinical studies have identified links between cholinergic signaling and depression in human subjects. Increased cholinergic signaling in hippocampus also increases behaviors related to anxiety and depression in mice, which can be reversed by acetylcholine receptor antagonists. EXPERIMENTAL APPROACH: Since the α7 subunit of the nicotinic acetylcholine receptor (nAChR) is highly expressed in hippocampus, we determined whether blocking α7 nAChRs could reverse effects of increased ACh signaling in anxiety- and depression-related behaviors in mice...

OBJECTIVES: The number of children in the United States utilizing emergency department (ED) services for psychiatric crises is increasing, and psychiatric-related ED visits disproportionately burden hospital resources. Yet, there is limited available information on the epidemiology and outcomes of pediatric mental health emergencies. The present study sought to characterize pediatric mental health-related ED presentations in a large urban center and identify factors predictive of inpatient hospitalization...

REVIEW
Mandakh Bekhbat, Gretchen N Neigh
Women appear to be more vulnerable to the depressogenic effects of inflammation than men. Chronic stress, one of the most pertinent risk factors of depression and anxiety, is known to induce behavioral and affective-like deficits via neuroimmune alterations including activation of the brain's immune cells, pro-inflammatory cytokine expression, and subsequent changes in neurotransmission and synaptic plasticity within stress-related neural circuitry. Despite well-established sexual dimorphisms in the stress response, immunity, and prevalence of stress-linked psychiatric illnesses, much of current research investigating the neuroimmune impact of stress remains exclusively focused on male subjects...

INTRODUCTION: Sex-related differences in clinical manifestations and consequences of Parkinson's disease (PD) have been poorly explored. Better understanding of sexual dimorphism in neurologic diseases such as PD has been announced as a research priority. The aim of our study was to determine independent sex differences in clinical manifestations and subtypes, psychosocial functioning, quality of life (QoL) and its domains between male and female individuals with PD. PATIENTS AND METHODS: A comprehensive list of demographics, motor symptoms and subtypes, nonmotor features, health-related quality of life (HRQoL), psychosocial functioning and general aspects of daily life was assessed in 157 individuals (108 males and 49 females) with idiopathic PD...

Although a number of studies have observed that females respond better to serotonergic antidepressants than males and that postmenopausal females have a diminished response to antidepressants compared with younger females, there are also studies that conflict with both of these findings, making any generalizations regarding sex differences difficult to make. Sex variance in antidepressant efficacy and pharmacokinetics profiles have been attributed to sex-based physiological differences, behavioral differences, related disorders, and sex-specific conditions, including pregnancy and menopause...
