Diffuse traumatic brain injury (TBI) initiates secondary pathology, including inflammation and reduced myelination. Considering these injury-related pathologies, the many states of activated microglia as demonstrated by differing morphologies would form, migrate, and function in and through fields of growth-inhibitory myelin byproduct, specifically Nogo. Here we evaluate the relationship between inflammation and reduced myelin antigenicity in the wake of diffuse TBI and present the hypothesis that the Nogo-66 receptor antagonist peptide NEP(1-40) would reverse the injury-induced shift in distribution of microglia morphologies by limiting myelin-based inhibition...

INTRODUCTION: There are higher levels of alcohol misuse in the military compared to the general population. Yet there is a dearth of research in military populations on the longitudinal patterns of alcohol use. This study aims to identify group trajectories of alcohol consumption in the UK military and to identify associations with childhood adversity, deployment history and mental disorder. METHODS: Data on weekly alcohol consumption across an eight year period and three phases of a UK military cohort study (n=667) were examined using growth mixture modelling...

Systemic administration of a Connexin43 mimetic peptide, Peptide5, has been shown to reduce secondary tissue damage and improve functional recovery after spinal cord injury (SCI). This study investigated safety measures and potential off-target effects of Peptide5 systemic administration. Rats were subjected to a mild contusion SCI using the New York University impactor. One cohort was injected intraperitoneally with a single dose of fluorescently labelled Peptide5 and euthanised at 2 or 4 h post-injury for peptide distribution analysis...

The persistence of shame-based reactions to child maltreatment (CM) has been associated with poor posttraumatic adjustment. Despite evidence that the postpartum period is a vulnerable time for women with CM histories, little is known about the consequences of maltreatment-specific (MS) shame for postpartum functioning. The current study examined individual differences in MS shame among a sample of women during the postpartum period ( n = 100) as well as prospective relations from MS shame to postpartum psychopathology at 6-, 12-, 15-, and 18-month postpartum...

OBJECTIVE: Although the death of a child is a devastating event, recent evidence shows that personal growth is a relevant outcome of parents' grief. This study aimed to examine the factors associated with posttraumatic growth (PTG) and to propose a multidimensional model consisting of sociodemographic, situational, and intrapersonal and interpersonal factors. METHOD: A sample (N = 197; 89.8% female; mean age = 39.44 years) of bereaved parents completed the Post-Traumatic Growth Inventory-Short Form, the 14-Item Resilience Scale, the Continuing Bonds Scale, and the Dyadic Coping Inventory...

The present study examined the validity of deriving a global or general measure of grief from the Persistent Complex Bereavement Inventory using an on-line survey of 180 bereaved adults. Confirmatory factor analyzes indicated that a hierarchical factor structure best fit the data such that an overarching, general grief factor accounted for the covariation among three first-order symptom clusters. The construct validity of this grief factor was further supported by correlations with related variables such as negative religious coping, neuroticism, meaning-made, and post-traumatic growth...

The nanosecond pulsed electric field (nsPEF) is investigated as an alternative plan for benign hepatic hydatid cyst. Altogether 72 C57B6 mice were included. Normal group (n = 12) had no parasite injection and the other 60 mice were used to induce hydatid cyst in liver by injecting protoscolices in portal vein. The liver hydatid cysts were exposed to nsPEF with different doses and then follow up. The standard surgery was performed as positive control. The hydatid cyst growth was monitored by ultrasound; the morphology was checked by gross anatomy and pathology was tested by H&E stain...

Pirfenidone is an anti-inflammatory and anti-fibrotic drug that has shown efficacy in lung and kidney fibrosis. Because inflammation and fibrosis have been linked to the progression of osteoarthritis, we investigated the effects of oral Pirfenidone in a mouse model of cartilage injury, which results in chronic inflammation and joint-wide fibrosis in mice that lack hyaluronan synthase 1 (Has1(-/-) ) in comparison to wild-type. Femoral cartilage was surgically injured in wild-type and Has1(-/-) mice, and Pirfenidone was administered in food starting after 3 days...

A new scoring system based on histo-morphology of mouse intervertebral disc (IVD) was established to assess changes in different mouse models of IVD degeneration and repair. IVDs from mouse strains of different ages, transgenic mice, or models of artificially-induced IVD degeneration were assessed. Morphological features consistently observed in normal, and early/later stages of degeneration were categorised into a scoring system focused on nucleus pulposus (NP) and annulus fibrosus (AF) changes. "Normal NP" exhibited a highly cellularised cell mass that decreased with natural ageing and in disc degeneration...

PURPOSE: Utilizing genetic overexpression of trophic molecules in cell populations has been a promising strategy to develop cell replacement therapies for spinal cord injury (SCI). Over-expressing the chemokine, stromal derived factor-1 (SDF-1α), which has chemotactic effects on many cells of the nervous system, offers a promising strategy to promote axonal regrowth following SCI. The purpose of this study was to explore the effects of human SDF-1α, when overexpressed by mesenchymal stem cells (MSCs), on axonal growth and motor behavior in a contusive rat model of SCI...

Mental health difficulties remain a major source of burden and distress for individuals, families, health and social care providers with stigma a key target for educational campaigns attempting to improve care pathways and access to support. Stigma is a multifaceted concept having a range of drivers including shame and is thought to act as a barrier to successful help seeking and engagement with support services. The current paper explores some of the salient themes that emerged from a British university drama project on the impact of symptoms and behaviours associated with a severe mental health condition on a young couple's relationship and reflects on the opportunities for connection with an audience provided by the medium and experience...

Thyroid hormone plays an important role in brain development and adult brain function, and may influence neuronal recovery after Traumatic Brain Injury (TBI). We utilized both animal and cell culture models to determine the effects of thyroid hormone treatment, post TBI or during hypoxia, on genes important for neuronal survival and neurogenesis. We show that TBI in rats is associated with a reduction in serum thyroxine (T4) and triiodothyronine (T3). A single dose of levothyroxine (T4), one hour after injury, increased serum T4 and normalized serum T3 levels...

This article aimed at identifying the positive emotions connected to spouse caregiving and the advantages for spouse carers. Theoretically, the article is based on the concept of emotion and the assumptions of positive psychology. Data search is conducted via electronic literature databases and the analysis method is partly theory-driven and partly inductive content classification. Our analyses discover and clarify the concepts associated with positive emotions in caring, such as the gains of caregiving, benefit-finding, finding meaning, personal growth, post-traumatic growth and resilience...

We present the case of a young man with an anterior inferior iliac spine (AIIS) avulsion fracture who was taking human growth hormone (HGH) at the time his injury was diagnosed. He presented with chronic hip pain and no traumatic event. Physical exam revealed symptoms of hip impingement. Upon imaging, he was diagnosed with an AIIS avulsion fracture and underwent surgical repair. He returned to full activity six months post-operatively. At 18-months post-operatively, he was pain-free and performing all activities without difficulty...

Traumatic brain injury (TBI) is a major cause of morbidity and mortality among young individuals worldwide. Understanding the pathophysiology of neurotrauma is crucial for the development of more effective therapeutic strategies. After the trauma occurs, immediate neurologic damage is produced by the traumatic forces; this primary injury triggers a secondary wave of biochemical cascades together with metabolic and cellular changes, called secondary neural injury. In the scenario of the acutely injured brain, the ongoing secondary injury results in ischemia and edema culminating in an uncontrollable increase in intracranial pressure...
