Pulmonary acariasis is a sporadic, incidental finding in colony-raised rhesus macaques (Macaca mulatta). Prophylactic treatment in indoor-raised and indoor-housed macaques is not routine due to low prevalence, lack of clinical significance, and potential risk of toxicosis. This case is an unusually severe infestation of Pneumonyssus simicola in an indoor-housed rhesus macaque, which ultimately resulted in this animal's death.

BACKGROUND: Options for male contraception are limited. The purpose of this study was to use a nonhuman primate model to evaluate Vasalgel™, a high molecular weight polymer being developed as a contraceptive device for men. METHODS: Sixteen adult male rhesus monkeys received intravas injections of Vasalgel, consisting of 25% styrene maleic acid in dimethyl sulfoxide. After a one-week recovery, males were returned to outdoor group housing, which included at least 3 and up to 9 intact, breeding females with a successful reproductive history...

Animal models of Zika virus (ZIKV) are needed to better understand tropism and pathogenesis and to test candidate vaccines and therapies to curtail the pandemic. Humans and rhesus macaques possess similar fetal development and placental biology that is not shared between humans and rodents. We inoculated 2 non-pregnant rhesus macaques with a 2015 Brazilian ZIKV strain. Consistent with most human infections, the animals experienced no clinical disease but developed short-lived plasma viremias that cleared as neutralizing antibody developed...

OBJECTIVE: Evaluating assessment validity is expected in neuropsychological evaluation, particularly in cases with identified secondary gain, where malingering or somatization may be present. Assessed with standalone measures and embedded indices, all within the testing portion of the examination, research on validity of self-report in the clinical interview is limited. Based on experience with litigation-involved examinees recovering from mild traumatic brain injury (mTBI), it was hypothesized that inconsistently reported date of injury (DOI) and/or loss of consciousness (LOC) might predict invalid performance on neurocognitive testing...

The liver can be an indicator of the health of an individual or of a group, which can be especially important to identify agents that can cause disease in multiple species. To better characterize hepatic lesions in stranded harbor porpoises (Phocoena phocoena), we analyzed the livers from 39 porpoises that stranded along the Dutch coast between December 2008 and December 2012. The animals were selected because they had either gross or histologic liver lesions with minimal autolysis and no evidence of trematode (Campula oblonga) infection...

Necrotizing meningoencephalitis (NME) affects toy and small breed dogs causing progressive, often fatal, inflammation and necrosis in the brain. Genetic risk loci for NME previously were identified in pug dogs, particularly associated with the dog leukocyte antigen (DLA) class II complex on chromosome 12, but have not been investigated in other susceptible breeds. We sought to evaluate Maltese and Chihuahua dogs, in addition to pug dogs, to identify novel or shared genetic risk factors for NME development. Genome-wide association testing of single nucleotide polymorphisms (SNPs) in Maltese dogs with NME identified 2 regions of genome-wide significance on chromosomes 4 (chr4:74522353T>A, p = 8...

Several studies have demonstrated the effect of an organization's culture and climate on the delivery of services to clients and the success of clinical outcomes. Workers' perceptions are integral components of organizational social context, and in order to create a positive organizational culture and climate, managers and frontline staff need to have a shared understanding of the social context. The existing literature does not adequately address that discrepancies in perceptions of culture and climate between frontline staff and managers impact the implementation of policies and services...

Tissue microarray (TMA) technology allows analysis of multiple tumour samples simultaneously on a single slide. The aim of the present study was to develop and assess a TMA containing 32 primary canine insulinomas and 13 insulinoma metastases. The results of histopathological and immunohistochemical analyses of triplicate core biopsies were compared with those of individual tissue sections using weighted κ statistics. Inter-observer agreement of TMA immunohistochemistry scores were assessed for chromogranin A (CgA), insulin, growth hormone (GH), growth hormone receptor (GHR) and Ki67 index, as well as the prognostic utility of clinicopathological, histopathological and immunohistochemical criteria...

A 10-year-old KWPN (Royal Warmblood Studbook of the Netherlands) gelding was euthanized after developing severe neurological symptoms preceded by severe epistaxis during laser treatment for progressive ethmoid haematoma (PEH) in the right nasal cavity. Postmortem examination of the head revealed a large amount of clotted blood between the right ventral and dorsal conchae in the nasal cavity and acute haemorrhage in the right subarachnoid space. Histologically, there was moderate, acute polioencephalomalacia in the neuropil adjacent to the haemorrhage...

Intestinal volvulus was recognized as the cause of death in 18 cetaceans, including 8 species of toothed whales (suborder Odontoceti). Cases originated from 11 institutions from around the world and included both captive (n = 9) and free-ranging (n = 9) animals. When the clinical history was available (n = 9), animals consistently demonstrated acute dullness 1 to 5 days prior to death. In 3 of these animals (33%), there was a history of chronic gastrointestinal illness. The pathological findings were similar to those described in other animal species and humans, and consisted of intestinal volvulus and a well-demarcated segment of distended, congested, and edematous intestine with gas and bloody fluid contents...

OBJECTIVE: After percutaneous endoscopic gastrostomy (PEG) tube placement, many surgeons will place an abdominal binder to protect the tube. Analysis of the literature shows mixed data as to the safety of abdominal binders with respect to pulmonary function. In this study, pulmonary function tests (PFTs) were used to assess changes in pulmonary status with and without an abdominal binder in volunteer active-duty personnel. DESIGN: Patient's forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced expiratory flow (FEF), peak expiratory flow (PEF) maximal inspiratory (P(i) max) and expiratory pressures (P(e) max), total lung capacity (TLC), vital capacity (VC), functional reserve capacity (FRC), expiratory reserve volume (ERV), and residual volume (RV) were measured with and without an elastic abdominal binder in prone, 30 degree and 60 degree positions in 5 male and 5 female active-duty personnel...

OBJECTIVE: Recent literature reports an increased risk of morbidity and mortality in nonemergency operations performed during nonregular duty hours at large institutions. Of the nonemergency operations performed after regular duty hours, appendectomies remain the most common. The study seeks to answer the question as to whether it is safe to continue performing appendectomies during non-normal duty hours at a low-volume institution. DESIGN: The study is a retrospective cohort review examining 102 appendectomies for suspected appendicitis over a 46-month period from July 2005 to May 2010...
