#1
Diane Swick, Julien Cayton, Victoria Ashley, And U Turken
Deficits in working memory (WM) and cognitive control processes have been reported in post-traumatic stress disorder (PTSD), in addition to clinical symptoms such as hypervigilance, re-experiencing, and avoidance of trauma reminders. Given the uncontrollable nature of intrusive memories, an important question is whether PTSD is associated with altered control of interference in WM. Some studies also suggest that episodic memory shows a material-specific dissociation in PTSD, with greater impairments in verbal memory and relative sparing of nonverbal memory...

BACKGROUND: A substantial amount of refugees (10-30%) suffer from Post-Traumatic Stress Disorder (PTSD). In Denmark there are different facilities specialised in psychiatric treatment of trauma-affected refugees. A previously published case report from such a facility in Denmark shows that some patients suffer from secondary psychotic symptoms alongside their PTSD. The aim of this study was to illustrate the characteristics and estimate the prevalence of psychotic features in a clinical population of trauma-affected refugees with PTSD...

Importance: Little is understood about how the symptoms of posttraumatic stress develop over time into the syndrome of posttraumatic stress disorder (PTSD). Objective: To use a network analysis approach to identify the nature of the association between PTSD symptoms in the acute phase after trauma and the chronic phase. Design, Setting, and Participants: A prospective cohort study enrolled 1138 patients recently admitted with traumatic injury to 1 of 4 major trauma hospitals across Australia from March 13, 2004, to February 26, 2006...

This paper presents the general characteristics of the phenomenon of autobiographical memory (AM), the current knowledge of the subject and describes hitherto identified distortions of AM in mental disorders.AM is the part of memory concerning the personal past of an individual. It includes episodic and semantic memories associated with an identity. It affects an activity and structuring of goals, it is set in human experience and emotions and it helps in creating plans. The evolutionary sig-nificance of AM is probably to facilitate short-term goal-oriented behaviors by comparing them with the previous ones...

OBJECTIVE: Recent developments in psychometrics enable the application of network models to analyze psychological disorders, such as PTSD. Instead of understanding symptoms as indicators of an underlying common cause, this approach suggests symptoms co-occur in syndromes due to causal interactions. The current study has two goals: (1) examine the network structure among the 20 DSM-5 PTSD symptoms, and (2) incorporate clinically relevant variables to the network to investigate whether PTSD symptoms exhibit differential relationships with suicidal ideation, depression, anxiety, physical functioning/quality of life (QoL), mental functioning/QoL, age, and sex...

BACKGROUND: Early traumatic experiences are thought to be causal factors in the development of trauma-related dissociative experiences, including depersonalization and derealization. The rubber hand illusion (RHI), a well-known paradigm that measures multi-sensorial integration of a rubber hand into one's own body representation, has been used to investigate alterations in the experience of body ownership and of body representation. Critically, however, it has never been studied in individuals with trauma-related disorders...

AIM AND OBJECTIVES: To determine the level of PTSS and to identify demographics, disease history, and clinical symptoms that were associated with PTSS among gynecological, breast, or colorectal cancer patients in Taiwan. BACKGROUND: Literature indicated that 7.3 % to 35.2% of patients with cancer had experienced level of post-traumatic stress symptoms (PTSS). However, the PTSS among patients with cancer in Taiwan was not documented. DESIGN: A cross-sectional study...

Spatially and temporally resolved measurements are of great importance in turbulent premixed flame studies, especially when investigating rapid processes such as when flame local extinction, re-ignition, or flashback occur in a reacting flow. Here, an experimental approach for simultaneously probing two different species at high frame rates (50 kHz) is presented by employing a multi-YAG laser system. The laser radiation at 355 nm generated by a multi-YAG laser system was split into two beam paths: one beam for exciting formaldehyde and the other for pumping an optical parametric oscillator (OPO)...

Hallucinogen persisting perception disorder (HPPD) is rarely encountered in clinical settings. It is described as a re-experiencing of some perceptual distortions induced while intoxicated and suggested to subsequently cause functional impairment or anxiety. Two forms exist: Type 1, which are brief "flashbacks," and Type 2 claimed to be chronic, waxing, and waning over months to years. A review of HPPD is presented. In addition, data from a comprehensive survey of 20 subjects reporting Type-2 HPPD-like symptoms are presented and evaluated...

BACKGROUND: The role of symptom overlap between major depressive disorder and posttraumatic stress disorder in comorbidity between two disorders is unclear. The current study applied network analysis to map the structure of symptom associations between these disorders. METHODS: Data comes from a sample of 909 Australian adults with a lifetime history of trauma and depressive symptoms. Data analysis consisted of the construction of two comorbidity networks of PTSD/MDD with and without overlapping symptoms, identification of the bridging symptoms, and computation of the centrality measures...

Adam D LaMotte, Christopher M Murphy
Objective: Research with partner-violent men has found that a subset of this population reports dissociative experiences during their violence (e.g., inability to remember violence [despite admission that it had occurred]; flashbacks during violence). However, the literature examining this phenomenon has been primarily limited to clinical observations and case studies, and there is a need for more thorough empirical investigation regarding the prevalence and correlates of dissociative violence among individuals in intimate partner violence (IPV) intervention programs...

BACKGROUND: Although loss of loved ones is a universal experience, individuals who experience this loss grieve in different ways. Complicated grief involves the development of trauma symptoms, such as flashbacks, anxiety, and fear associated with daily activities after a death that disrupts the healthy grieving process. Daily activities such as eating, meal planning, grocery shopping, managing finances, and household maintenance can become painful and isolating for those experiencing complicated grief...

INTRODUCTION: A consequence of the West Africa Ebola outbreak 2014-2015 was the unprecedented number of Ebola survivors discharged from the Ebola Treatment Units (ETUs). Liberia alone counted over 5,000 survivors. We undertook a qualitative study in Monrovia to better understand the mental distress experienced by survivors during hospitalization and reintegration into their community. METHODS: Purposively selected Ebola survivors from ELWA3, the largest ETU in Liberia, were invited to join focus group discussions...

Hermann A M Mucke
Among the psychedelic drugs that enjoyed a period of popularity in psychiatric research during the 1950s and 1960s, lysergic acid diethylamide (LSD) is the most prominent one. Psychiatrists of that time had seen LSD not only as a tool for psychotherapy but also as a potential therapeutic for anxiety, depression, alcohol abuse, autism, and even schizophrenia. When it became a quasi-religious epitome of the Hippie counterculture in the mid 1960s, and cases of what we now call hallucinogen persisting perception disorder and acute psychotic "flashbacks" mounted, authorities moved to make LSD illegal...

INTRODUCTION: Posttraumatic stress disorder (PTSD) is a highly prevalent disorder with important social consequences. Several models have been developed with the aim of understanding the mechanisms underlying its symptoms. Intrusions are idiosyncratic symptoms that commonly take the form of involuntary recollection of images or flashbacks about the traumatic event. OBJECTIVE: To review how memory is conceptualized in each of these models and the implications for clinical practice...

A total of 75 patients were diagnosed with the Structured Clinical Interview for DSM-IV Dissociative Disorders-Revised as having dissociative identity disorder (DID), and 100 patients were diagnosed with the Structured Interview for DSM-IV Personality as having borderline personality disorder (BPD). Both groups were administered the Multidimensional Inventory of Dissociation (MID). DID patients had significantly higher MID scores than BPD patients, different distributions of MID scores, and different MID subscale profiles in 3 ranges of MID scores (0-15, 15-30, 30-45)...

PURPOSE: This mixed-methods exploratory study identified and then developed and validated a quantitative measure of a new construct of mental suffering in the occupied Palestinian territory: feeling broken or destroyed. METHODS: Group interviews were conducted in 2011 with 68 Palestinians, most aged 30-40, in the West Bank, East Jerusalem, and the Gaza Strip to discern local definitions of functioning. Interview participants articulated of a type of suffering not captured in existing mental health instruments used in regions of political conflict...

REVIEW
María F Coronel, Florencia Labombarda, Susana L González
The present review discusses the potential role of neurosteroids/neuroactive steroids in the regulation of nociceptive and neuropathic pain, and recapitulates the current knowledge on the main mechanisms involved in the reduction of pain, especially those occurring at the dorsal horn of the spinal cord, a crucial site for nociceptive processing. We will make special focus on progesterone and its derivative allopregnanolone, which have been shown to exert remarkable actions in order to prevent or reverse the maladaptive changes and pain behaviors that arise after nervous system damage in various experimental neuropathic conditions...

LSD was introduced in psychiatry in the 1950s. Between 1960 and 1973, nearly 400 patients were treated with LSD in Denmark. By 1964, one homicide, two suicides and four suicide attempts had been reported. In 1986 the Danish LSD Damages Law was passed after complaints by only one patient. According to the Law, all 154 applicants received financial compensation for LSD-inflicted harm. The Danish State Archives has preserved the case material of 151 of the 154 applicants. Most of the patients suffered from severe side effects of the LSD treatment many years afterwards...
