BACKGROUND: Injuries inflicted by gunshot wounds (GSWs) are an immense burden on the South African (SA) healthcare system. In 2005, Allard and Burch estimated SA state hospitals treated approximately 127 000 firearm victims annually and concluded that the cost of treating an abdominal GSW was approximately USD1 467 per patient. While the annual number of GSW injuries has decreased over the past decade, an estimated 54 870 firearm-related injuries occurred in SA in 2012. No study has estimated the burden of these GSWs from an orthopaedic perspective...

The Lifetime Assessment of Violent Acts (LAVA) inventory provides estimates of the frequency, triggers, and consequences (including injuries to others) of historic acts of aggression. The LAVA also identifies the situational contexts in which prior violence was triggered and allows classifications based on past reactive, intimate partner, alcohol-related, and/or weapon-related violence. Normative and psychometric data were provided from a college (N = 1,133) and general population (N = 545) sample. Around 15% of the general population sample recalled inflicting 5 or more injuries on others at some time in the past...

BACKGROUND: Prior research suggests that United States governmental sources documenting the number of law-enforcement-related deaths (i.e., fatalities due to injuries inflicted by law enforcement officers) undercount these incidents. The National Vital Statistics System (NVSS), administered by the federal government and based on state death certificate data, identifies such deaths by assigning them diagnostic codes corresponding to "legal intervention" in accordance with the International Classification of Diseases-10th Revision (ICD-10)...

The specific features of soot deposition after a shot fired from the Kalashnikov AK-74 assault rifle are determined by the influence of the multiple factors, with the effect of the muzzle brake (MB) designed to enhance fire density and decrease the fire recoil energy being prevalent over other factors. The special windows, slots and holes in the muzzle brake mechanism are responsible for the appearance of the specific topographic features of soot deposition formed by the combustion gases passing through the assembly...

Sound stress (SS) elicits behavioral changes, including pain behaviors. However, the neuronal mechanisms underlying SS-induced pain behaviors remain to be explored. The current study examined the effects of SS on nociceptive behaviors and changes in expression of the spinal corticotropin-releasing factor (CRF) system in male Sprague Dawley rats with and without thermal pain. We also studied the effects of SS on plasma corticosterone and fecal output. Rats were exposed to 3 days of SS protocol (n = 12/group)...

Parenting after pregnancy loss is often complicated for people who have not effectively grieved the loss and worked through the trauma. Reproductive losses can trigger shame and self-doubt, damage the sense of self-as-parent, and inflict narcissistic injuries, which, in turn, may impede the resolution of grief. If not addressed, these unresolved feelings may be projected onto subsequent children, potentially disrupting attachment relationships and the child's sense of self. The reproductive story, a lifelong internal narrative that comprises the thoughts, feelings, and hopes about how parenting and adulthood will unfold, and forms the core of parental identity, can be used as a tool in helping parents understand the depth of their feelings, integrate current and past losses into the self, and resolve grief...

The aim of the study was to characterize the profile of victims of self-inflicted injuries, who were attended at urgent and emergency care services in Brazilian state capitals, by using the "Viva Survey" database of 2014. Descriptive statistics of the self-inflicted injuries by gender, as well as logistic regression analysis, were performed. The evaluated characteristics were age, gender, race/skin color, education, area of residence, characteristics of the event, alcohol use and the outcome of the case. The results showed that almost 10% of the surveyed cases that were treated by emergency medical services in relation to violence were due to self-inflicted injuries: of particular note were the cases involving females and adults...

Penetrating brain injuries from gunshot wounds can carry a poor prognosis and require an aggressive, multifaceted approach to obtain a good prognosis and outcome. An initial evaluation requires appropriate imaging studies followed by management and prophylaxis against increased intracranial pressure, infection, and seizures. Surgical management is then followed to ensure the watertight closure of any wounds, removal of any areas of hematoma, and removal of any potential areas of infection. In this paper, we report the case of a patient who presented with a self-inflicted gunshot wound to the head and then received aggressive medical and surgical management...

A B Riber, D A Guzman
Injurious pecking (IP) remains one of the major welfare challenges in housing of laying hens worldwide due to the negative consequences it inflicts on animal welfare and economy. One potential solution to reduce IP is the use of dark brooders as the primary heat source during rearing. The objective was to investigate effects of rearing layer chicks with different management strategies and size allowances of dark brooders on IP and production-related traits during rear and lay. Groups of 100 to 103 Isa Warren chicks were reared either with one of 4 brooder types (n = 4 per treatment) or with whole-house heating (control: n = 6)...

A stem cell's epigenome directs cell fate during development, homeostasis, and regeneration. Epigenetic dysregulation can lead to inappropriate cell fate decisions, aberrant cell function, and even cancer. The histone variant macroH2A has been shown to influence gene expression, guide cell fate, and safeguard against genotoxic stress. Interestingly, mice lacking functional macroH2A histones (hereafter referred to as macroH2A DKO) are viable and fertile; yet suffer from increased perinatal death and reduced weight and size compared to wildtype (WT)...

Estimation of age and vitality of burn injury both in the living and dead is essential in forensic practice. Nitric oxide and interleukin-6 (IL-6) play an important role in skin burn healing. In this study, the expression of inducible nitric oxide synthase (iNOS) and IL-6 proteins during skin burn healing in rats was studied for purposes of burn dating and to differentiate between ante-mortem and post-mortem burn. Ante-mortem skin burns were created on forty five rats. Normal and burnt skin samples were taken at 1, 3, 5, 7, 9, 11, 13, 15 and 21 days following burn induction (5 rats for each stage)...

High sensitivity and reactivity to behaviors of family members characterizes several forms of psychopathology, including self-inflicted injury (SII). We examined mother-daughter behavioral and psychophysiological reactivity during a conflict discussion using nonlinear dynamics to assess asymmetrical associations within time-series data. Depressed, SII, and control adolescents and their mothers participated (n=76 dyads). We expected that (1) mothers' evocative behaviors would affect behavioral and psychophysiological reactivity among depressed and, especially, SII adolescents, (2) adolescents' behaviors would not evoke mothers' behavioral or physiological reactivity, and (3) control teens and mothers would be less reactive, with no dynamic associations in either direction...

BACKGROUND: Animal models of spinal cord injuries aim to utilize controlled and reproducible conditions. However, a literature review reveals that mouse contusion studies using equivalent protocols may show large disparities in the observed impact force vs. cord compression relationship. The overall purpose of this study was to investigate possible sources of bias in these measurements. The specific objective was to improve spinal cord compression measurements using a video-based setup to detect the impactor-spinal cord time-to-contact...

Dimethyl fumarate (DMF) is an immunomodulatory therapeutic for multiple sclerosis and psoriasis with neuroprotective potential. Its mechanism of action involves activation of the antioxidant pathway regulator Nuclear factor erythroid 2-related factor 2 (Nrf2) thereby increasing synthesis of the cellular antioxidant glutathione (GSH). The objective of this study was to investigate whether post-traumatic DMF treatment is beneficial after experimental traumatic brain injury (TBI). Adult C57Bl/6 mice were subjected to controlled cortical impact followed by oral administration of DMF (80 mg/kg body weight) or vehicle at 3 h, 24 h, 48 h and 72 h after the inflicted TBI...
