Importance Exposure to trauma increases the risk for developing threat (ie, fear) symptoms, such as reexperiencing and hyperarousal symptoms, and loss (ie, dysphoria) symptoms, such as emotional numbing and depressive symptoms. While preclinical data have implicated the activated dynorphin/?-opioid receptor (KOR) system in relation to these symptoms, the role of the KOR system in mediating these phenotypes in humans is unknown. Elucidation of molecular targets implicated in threat and loss symptoms is important because it can help inform the development of novel, mechanism-based treatments for trauma-related psychopathology.

Importance The DSM-5 classifies mood and anxiety disorders as separate conditions. However, some studies in adults find a unidimensional internalizing factor that underpins anxiety and depression, while others support a bidimensional model where symptoms segregate into distress (depression and generalized anxiety) and fear factors (phobia subscales). However, little is known about the phenotypic and genetic structure of internalizing psychopathology in children and adolescents.

Abstract: Objectives: This study investigates the possibility of introducing depression and developmental screening tools into the National Programme on Immunization (NPI) in southeast Nigeria. The specific objectives were to determine the prevalence of postpartum depression (PPD) among mothers attending immunization clinics and to assess the association of maternal PPD and infant growth in relation to World Health Organization (WHO) recommendations.Methods: Four hundred and eight (408) mothers completed the sociodemographic questionnaire and the self-report Edinburgh Postnatal Depression Scale (EPDS).

Abstract: Objective: Little attention has been paid to the role of holding back sharing concerns in the psychological adaptation of women newly diagnosed with gynecological cancers. The goal of the present study was to evaluate the role of holding back concerns in psychosocial adjustment and quality of life, as well as a possible moderating role for emotional expressivity and perceived unsupportive responses from family and friends.Method: Two hundred forty-four women diagnosed with gynecological cancer in the past 8 months completed measures of holding back, dispositional emotional expressivity, perceived unsupportive responses from family and friends, cancer-specific distress, depressive symptoms and quality of life.Results: Emotional expressivity moderated the association between holding back and cancer-specific distress and quality of life, but not depressive symptoms. Greater holding back was more strongly associated with higher levels of cancer-related distress among women who were more emotionally expressive than among women who were less expressive.

Abstract: Objective: Posttraumatic stress disorder (PTSD) is significantly and positively associated with several physical conditions. We aimed to examine whether the nature and number of trauma(s) experienced may be related to physical conditions using a population-based sample.Methods: Data came from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (N=34, 653; age 20 years and older).

In a recently published paper in General Hospital Psychiatry , we described the association between a diagnosis of a serious mental illness and a chronic pain condition. In a national sample of all patients who utilized services from the Veterans Health Administration within a given year, those individuals with schizophrenia and bipolar disorder were significantly more likely to have a chart diagnosis of chronic pain compared to those without these psychiatric diagnoses. We concluded that this line of research has important implications for understanding how chronic pain might impact mental health recovery.
