The risk of harm/injury in homes where intimate partner violence (IPV) occurs is not limited to humans; animals reside in as many as 80% of these homes and may be at substantial risk of suffering severe or fatal injury. Gaining a better understanding of IPV-pet abuse overlap is imperative in more accurately identifying the risks of harm for all individuals and animals residing in these homes. The objectives of this study were to utilize law enforcement officers' observations and IPV victim reports from the scene of the incident to (a) determine the prevalence of pet abuse perpetration among suspects involved in IPV incidents, (b) compare characteristics of IPV incidents and the home environments in which they occur when the suspect has a history of pet abuse with incidents involving suspects with no reported history of pet abuse, and (c) compare IPV incident outcomes involving suspects with a history of pet abuse with those involving suspects with no reported history of pet abuse...

The host-restricted pathogen Streptococcus equi causes strangles in the horse, which is characterised by abscessation of the lymph nodes of the head and neck. The disease is endemic throughout the world causing considerable welfare and economic cost to the horse industry. Here we report the results of three studies where ponies were vaccinated with combinations of recombinant fusion proteins to optimise vaccine production and the level of protection conferred. Optimal protection was conferred by a prototype multicomponent subunit vaccine, Strangvac 4, which contained eight proteins CNE, SclC, SclF, SclI, EAG (fused as CCE), SEQ_402, SEQ_0256 (fused as Eq85) and IdeE...

Age at first marriage has risen substantially and birth rates are at a record low; people are spending more time in relationships that, by comparison, have fewer emotional, financial, and legal commitments. Little research has examined intimate partner violence (IPV) prevalence in current and former adult (vs. adolescent) dating relationships. Such information is relevant to federal firearms policies that are based on the nature of an intimate relationship. We examined assaultive behaviors by the type and status of the relationship - current spouse, former spouse, current boyfriend or girlfriend, and former boyfriend or girlfriend - in 31,206 IPV incidents responded to by Philadelphia police in 2013...

This case of sexually motivated homicide combined the perpetrator's obliteration of his victim's identity along with his attempt at concealment of the corpse and sexual gratification following ligature strangulation of a young unidentified female from a minority Indian state. Sexual bondage was evident with characteristic body tying in a typical posture to fuel the killer's sexual arousal and gratification before, during and then after strangling his victim with a scarf. The victim's body was left in a sack packed with vegetables and transported from the crime site and found abandoned in a park...

Streptococcus equi subsp. equi is the etiologic agent of strangles, an infectious disease affecting the upper respiratory tract and head and neck lymph nodes of equines. Routine antimicrobial therapy includes penicillin (PEN) as antibiotic of first choice. Streptococci are usually susceptible to PEN and only a few antimicrobial studies had been performed. The aim of this work was to study the antimicrobial susceptibility profile of S. equi from Buenos Aires, Argentina. Ninety-two isolates were studied by the single disk method to PEN, cefotaxime, erythromycin (ERY), tetracycline, enrofloxacin (ENR), trimethoprim sulfamethoxazole (TMS), ciprofloxacin, clindamycin (CLI), streptomycin (STR) and florfenicol...

PURPOSE: Because identification of intimate partner violence (IPV) in health care settings is low and strangulation increases lethality risk among women experiencing IPV, we examined the prevalence and correlates of nonfatal strangulation among 1,008 women survivors of IPV. METHODS: Trained researchers conducted semistructured interviews with women survivors of IPV referred by police. Multinomial logistic regression examined differential correlates of attempted, completed, and multiple strangulation...

In eastern North America, the field milkweed, Asclepias syriaca L. (Asclepiadaceae), is used in planting schemes to promote biodiversity conservation for numerous insects including the endangered monarch butterfly, Danaus plexippus (Linnaeus) (Nymphalidae). Less is known about its pollinators, and especially in urban habitats where it is planted often despite being under increasing pressure from invasive plant species, such as the related milkweed, the dog-strangling vine (DSV), Vincetoxicum rossicum (Kleopow) Barbar...

INTRODUCTION: A De Garengeot hernia is a rare form of femoral hernia, where the appendix is found in the herniated sac. This feature is important to report, as both the diagnosis and the treatment are quite challenging in this particular condition. PRESENTATION OF CASE: We report the case of a 77-year-old female presenting with a femoral hernia, containing an incarcerated necrotic vermiform appendix (De Garengeot hernia). A laparoscopic appendectomy was performed and the herniated defect was repaired according to Rives technique, using a biological mesh...

The Gram-positive bacterium Streptococcus equi subspecies equi (S. equi) is the causative agent of strangles, among the most frequently diagnosed infectious diseases of horses worldwide. Genome analysis of S. equi strain 4047 (Se4047) identified a putative operon, Fim1, with similarity to the pilus loci of other Gram-positive bacteria. The Fim1 locus was present in all strains of S. equi and its close relative S. equi subspecies zooepidemicus (S. zooepidemicus) that have been studied to date. In this study we provide evidence that the putative structural pilus proteins, SEQ_0936 and CNE, are produced on the cell surface during in vitro growth and in vivo infection...

Strangulation of the gallbladder associated with the omentum is extremely rare and, to our knowledge, only two cases have been previously reported. The patient was a 91-year-old female who presented to our emergency room with a chief complaint of upper abdominal pain. Computed tomography imaging revealed a gourd-shaped gallbladder with biphasic appearance divided clearly at the body. In the fundus side, the wall of the gallbladder was oedematous and thickened, while the neck side was intact. On the second day after onset, a laparoscopic cholecystectomy was performed...

Nineteenth-century psychiatry shifted its focus to the brain as the seat of mental disorders. With a new understanding of mental disorders arose the need to consult forensic psychiatrists in cases of criminal acts committed by persons with mental illness. This article focuses on three murders committed by 'epileptics' at the end of the nineteenth and the beginning of the twentieth centuries in Croatia. An analysis of these cases will help to situate forensic psychiatry at the turn of the century within the Austro-Hungarian Empire, and reveal the authority that forensic experts wielded in the courts...

Nonalcoholic fatty liver diseases (NAFLD) is one of the most common chronic liver disease in Western countries. Oxygen is a central component of the cellular microenvironment, which participate in the regulation of cell survival, differentiation, functions and energy metabolism. Accordingly, sufficient oxygen supply is an important factor for tissue durability, mainly in highly metabolic tissues, such as the liver. Accumulating evidence from the past few decades provides strong support for the existence of interruptions in oxygen availability in fatty livers...

Hendra virus is a zoonotic paramyxovirus, which causes severe respiratory and neurological disease in horses and humans. Since 2012, the Hendra virus sub-unit G vaccine has been available for horse vaccination in Australia. Uptake of the vaccine has been limited and spill-over events of Hendra virus infection in horses continue to occur. We conducted an online, questionnaire-based cross-sectional study of 376 horse owners belonging to a variety of different equestrian clubs in Queensland, Australia, to identify risk factors for non-vaccination against Hendra virus...

BACKGROUND: Mutations in the nuclear-encoded mitochondrial DNA polymerase gamma (POLG) can result in a wide spectrum of neurological deficits. A common presentation is progressive ataxia (POLG-A) which includes impaired speech and swallowing. The nature, severity and impact of these deficits in POLG-A is not known. A comprehensive quantitative and qualitative characterization of dysarthria and dysphagia in this recurrent ataxia disorder will assist in diagnostics, provide insights into the underlying pathology, and establish the foundation for future therapy trials...
