Bikram Sekhon
PURPOSE: Mental health nursing is not the same as psychiatry, so it is important for nurses to have an understanding of the defining attributes, antecedents, consequences, model cases, and empirical referents of post-traumatic stress disorder (PTSD). METHOD: Walker and Avant's (2005) method is used to guide this concept analysis of PTSD. FINDINGS: Four attributes arise from this concept analysis, which are addressed through both the DSM-IV and DSM-5 (American Psychiatric Association, /): triggering event or events, re-experiencing, fear, and helplessness...

AIMS AND OBJECTIVE: Drawing on the findings of a grounded theory study aimed at exploring how power is exercised in nurse-manager relationships in the hospital setting, this paper examines the empirical and pragmatic adequacy of grounded theory as a methodology to advance the concept of empowerment in the area of nursing leadership and management. BACKGROUND: The evidence on staff nurse empowerment has highlighted the magnitude of individual and organizational outcomes, but has not fully explicated the micro-level processes underlying how power is exercised, shared or created within the nurse-manager relationship...

The present study sought to investigate the association between selective attentional processing of body images, rumination, and eating disorder symptoms in young women. Seventy-three undergraduate female students (ages 17-24) completed a modified dot-probe task to assess whether young women showed a differential attentional bias pattern towards thin and non-thin female bodies. Participants also completed self-report measures of eating disorder pathology. It was found that increased reports of dietary restraint and body dissatisfaction were associated with both greater attentional bias towards thin bodies and avoidance of non-thin bodies (as compared to neutral images), although the former relationship was stronger than the latter...

Arrhythmogenesis in acute myocardial infarction (MI) is associated with depolarization of resting membraine potential (RMP) and decrease of inward rectifier potassium current (IK1) in cardiomyocytes. However, clinical anti-arrhythmic agents that primarily act on RMP by enhancing the IK1 channel are not currently available. We hypothesized that zacopride, a selective and moderate agonist of the IK1/Kir2.1 channels, prevents and cures acute ischemic arrhythmias. To test this viewpoint, adult Sprague-Dawley (SD) rats were subjected to MI by ligating the left main coronary artery...

After HIV diagnosis, heterosexuals in high-poverty urban areas evidence delays in linkage to care and antiretroviral therapy initiation compared to other groups. Yet barriers to/facilitators of HIV care among these high-risk heterosexuals are understudied. Under the theory of triadic influence, putative barriers to HIV care engagement include individual/attitudinal-level (e.g., fear, medical distrust), social-level (e.g., stigma), and structural-level influences (e.g., poor access). Participants were African-American/Black and Hispanic adults found newly diagnosed with HIV (N = 25) as part of a community-based HIV testing study with heterosexuals in a high-poverty, high-HIV-incidence urban area...

Although anti-angiogenic (AA) therapy is widely used in clinical practice, it is often challenged by insufficient efficacy and intrinsic resistance. Some studies have reported that AA therapy can even increase tumor metastasis. However, whether this is due to a specific AA drug causing a specific tumor to metastasize or because the anti-angiogenic theory has some "inherent vice" that may inevitably lead to tumor dissemination remains a mystery. Herein, we designed a model that completely blocks tumor blood supply using a physical barrier to examine tumor behavior in such circumstances...

BACKGROUND: Changing health care systems depend on strong organizational leadership that realizes the collaborative potential of both physician and nonphysician leaders. PURPOSE: The aim of this study was to seek insight into the everyday health care leader experience by examining 24 physician and nonphysician leaders working in the U.K. National Health Service. We explored (a) how they make sense of and act with respect to specific collaborative tensions in their interactions and (b) which aspects of their everyday leadership contexts heighten the probability for producing and resolving such tensions...

BACKGROUND: There continues to be significant investment in the detection of genotype × environment interaction (G × E) in psychiatric genetics. The implications of the method of assessment for the genetic analysis of psychiatric disorders are examined for simulated twin data on symptom scores and environmental covariates. METHODS: Additive and independent genetic and environmental risks were simulated for 10,000 monozygotic (MZ) and 10,000 dizygotic (DZ) twin pairs and the 'subjects' administered typical simulated checklists of clinical symptoms and environmental factors...

BACKGROUND AND OBJECTIVES: Current guidelines for neuraxial analgesia in patients with multiple sclerosis are ambiguous and offer the clinician only a limited basis for decision making. This systematic review examines the number of cases in which multiple sclerosis has been exacerbated after central neuraxial analgesia in order to rationally evaluate the safety of these procedures. METHODS: A systematic literature search with the keywords "anesthesia or analgesia" and "epidural, peridural, caudal, spinal, subarachnoid or intrathecal" in combination with "multiple sclerosis" was performed in the databases PubMed and Embase, looking for clinical data on the effect of central neuraxial analgesia on the course of multiple sclerosis...

C-terminal Binding Proteins (CtBP) 1 and 2 are oncogenic transcriptional co-regulators overexpressed in many cancer types, with their expression level correlating to worse prognostic outcomes and aggressive tumor features. CtBP negatively regulates the expression of many tumor suppressor genes, while coactivating genes that promote proliferation, epithelial-mesenchymal transition, and cancer stem cell self-renewal activity. In light of this evidence, the development of novel inhibitors that mitigate CtBP function may provide clinically actionable therapeutic tools...

OBJECTIVE: Increasing evidence supports the efficacy of body-oriented psychotherapy (BPT) for schizophrenia. Yet, so far no research has investigated outcome in relation to therapy process: Why and how BPT is effective. In this study, we qualitatively explore participants' experience of a manualized BPT for schizophrenia to shed light on the process of therapeutic change. METHOD: We conducted in-depth interviews with 6 participants who completed a 10-week BPT group intervention...

BACKGROUND: Anhedonia, the decreased interest and pleasure, is often described as 'flat' or 'blunted' positive affect (PA). Yet, little is known about PA functioning in anhedonic individuals' daily lives. The current study investigates PA reactivity to pleasurable experiences in anhedonia together with its relevant temporal dynamics (i.e., variability, instability, and inertia), and expands current knowledge by exploring the role of arousal therein. METHODS: Using the Experience Sampling Method (ESM), we collected 90 assessments of real-life PA experiences across 30 days in 18-24 year old individuals with anhedonia (N=69) and without anhedonia (N=69)...

BACKGROUND: Smoking cessation fatigue, or tiredness of attempting to quit smoking, has been posited as a latent construct encompassing loss of motivation, loss of hope in cessation success, decreased self-efficacy, and exhaustion of self-control resources. Despite the potential clinical impact of characterizing cessation fatigue, there is currently no validated measure to assess it. Using a rational scale development approach, we developed a cessation fatigue measure and examined its reliability and construct validity in relation to a) smokers' experience of a recently failed quit attempt (QA) and b) readiness to engage in a subsequent QA...

This article explores overlap of symptoms between autism and attachment difficulties and suggests innovative solutions based on formulation. Currently, clinicians express difficulties in differentiating between these conditions contributing to misdiagnosis. Research into the prevalence of attachment difficulties among children with autism often fails to reflect detailed knowledge of attachment theory. Consequently, studies in this area employ questionable modifications to attachment measures and methods of analysis...

Psychiatric practice in India is marked by an increasing gulf between largely urban-based mental health professionals and a majority rural population. Based on the premise that any engagement is a mutually constructed humane process, an understanding of the culture of psychiatry including social process of local knowledge acquisition by trainee psychiatrists is critical. This paper reviews existing literature on training of psychiatrists in India, the cultural construction of their professional identities and autobiographical reflections...
