REVIEW
Gregg M Stave
PURPOSE OF REVIEW: This review explores animal allergen exposure in research laboratories and other work settings, focusing on causes and prevention. RECENT FINDINGS: (1) Consistent with the hygiene hypothesis, there is new evidence that early childhood exposure to pets produces changes in the gut microbiome that likely lead to a lower risk of allergy. (2) Anaphylaxis from laboratory animal bites occurs more frequently than suggested by prior literature. (3) Animal allergens represent an occupational hazard in a wide variety of work settings ranging from fields that work with animals to public settings like schools and public transportation where allergens are brought into or are present in the workplace...

BACKGROUND: Globally there are an estimated 390 million dengue infections per year, of which 96 million are clinically apparent. In Cambodia, estimates suggest as many as 185,850 cases annually. The World Health Organization global strategy for dengue prevention aims to reduce mortality rates by 50% and morbidity by 25% by 2020. The adoption of integrated vector management approach using community-based methods tailored to the local context is one of the recommended strategies to achieve these objectives...

Minimizing arthropod exposure (e.g. mosquito and tick bites) is vital to protect health of outdoor workers. Personal protective measures can help protect against exposure. Here, the quantity of permethrin was evaluated for different fabric types after washing. Cone and petri dish exposure assays were used to investigate the knockdown/mortality of permethrin-susceptible and permethrin-resistant populations of mosquitoes. Permethrin-treated clothing was effective against the tested mosquito population that was susceptible to permethrin but not a permethrin-resistant population...

BACKGROUND & AIMS: The aim of this study was to examine differences in the validity of a visual estimation method for determining patients' meal intake between various meal types and supplied food items in hospitals and to find factors influencing the validity of a visual estimation method. METHODS: There are two procedures by which we obtained the information on dietary intake of the patients in these hospitals. These are both by visual assessment from the meal trays at the time of their clearing, by the attending nursing staff and by weighing conducted by researchers...

Kissing bugs possess a highly developed thermal sense and when starved, they attempt to bite any object which temperature is close to that of a warm-blooded host. At each feeding event, these insects take massive meals in just a few minutes. One could then expect fed-bugs being heated-up by the ingested warm blood and so becoming attractive to starved conspecifics. This is not however the case, arising the question about why cannibalism is very rare among these insects. Recently, the ability of thermoregulating during feeding has been demonstrated in Rhodnius prolixus...

Paranasal sinuses are highly variable among living and fossil hominins and their function(s) are poorly understood. It has been argued they serve no particular function and are biological 'spandrels' arising as a structural consequence of changes in associated bones and/or soft tissue structures. In contrast, others have suggested that sinuses have one or more functions, in olfaction, respiration, thermoregulation, nitric oxide production, voice resonance, reduction of skull weight, and craniofacial biomechanics...

Open wounds are a major health risk in animals, with species prone to injuries likely developing means to reduce these risks. We therefore analysed the behavioural response towards open wounds on the social and individual level in the termite group-hunting ant Megaponera analis During termite raids, some ants get injured by termite soldiers (biting off extremities), after the fight injured ants get carried back to the nest by nest-mates. We observed treatment of the injury by nest-mates inside the nest through intense allogrooming at the wound...

Blood feeding is an essential and signature activity of the medicinal leech species, Hirudo verbana Despite keen interest in understanding the neuronal substrates of this behavior, a major component of the nervous system associated with feeding has remained overlooked. In this study, for the first time, we report on the presence and characteristics of five stomatogastic ganglia (STGs) comprising the visceral stomatogastric nervous system (STN) of the leech. Although Hanke (1948) provided a brief report that a ring of three ganglia (not five) was associated with the cephalic ganglia, this information was never integrated into subsequent neurobiological studies of feeding...

Insect head shapes are remarkably variable but the influences of these changes on biomechanical performance are unclear. Among "basal" winged insects, such as dragonflies, mayflies, earwigs, and stoneflies, some of the most prominent anatomical changes are the general mouthpart orientation, eye size and the connection of the endoskeleton to the head. Here, we assess these variations as well as differing ridge and sclerite configurations using modern engineering methods including multibody dynamics modelling and finite element analysis in order to quantify and compare the influence of anatomical changes on strain in particular head regions and the whole head...

Lyme disease is a serious vector-borne infection that is caused by the Borrelia burgdorferi sensu lato family of spirochetes, which are transmitted to humans through the bite of infected Ixodes ticks. The primary etiological agent in North America is Borrelia burgdorferi sensu stricto. As geographic risk regions expand, it is prudent to support robust surveillance programs that can measure tick infection rates, and communicate findings to clinicians, veterinarians, and the general public. The molecular technique of nested polymerase chain reaction (nPCR) has long been used for this purpose, and it remains a central, inexpensive, and robust approach in the detection of Borrelia in both ticks and wildlife...

BACKGROUND: Human bites involving the genitalia rarely present to the emergency department (ED). They have the potential to cause life-threatening secondary infections as well as serious physical and functional damage. CASE REPORT: We report a case of an adult male who sustained a human bite to the scrotum, resulting in a ragged laceration on the anterior scrotum, with a devascularized flap and necrotic edges overlying the wound. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Human bites to the scrotum are rare and, hence, the experience of emergency physicians treating patients presenting with these injuries may be minimal...

BACKGROUND: Previous studies have identified risk factors for dog bites in children, but use data from individual trauma centers, with limited generalizability. This study identifies a population risk profile for pediatric dog bites using the National Trauma Data Bank. We hypothesized that the population at risk was younger boys, that such bites occur at home, are moderately severe, and are on the face or neck. METHODS: For this retrospective cross-sectional study, a sample of 7912 children 17 years old and younger with International Classification of Diseases (ICD)-9 event code E906...

BACKGROUND: Dog bite studies are typically based on hospital records and may be biased towards bites requiring significant medical treatment. This study investigated true dog bite prevalence and incidence at a community-level and victim-related risk factors, in order to inform policy and prevention. METHODS: A cross-sectional study of a community of 1280 households in Cheshire, UK, surveyed 694 respondents in 385 households. Data included dog ownership and bite history, demographics, health and personality (Ten Item Personality Inventory (TIPI) brief measure)...

PURPOSE: Immunotherapy with bispecific T cell engagers has achieved striking success against hematological malignancies, but efficacy against solid tumors has been limited. We hypothesized that oncolytic measles viruses encoding bispecific T cell engagers (MV-BiTEs) represent a safe and effective treatment against solid tumors through local BiTE expression, direct tumor cell lysis and in situ tumor vaccination. EXPERIMENTAL DESIGN: To test this hypothesis, we generated MV-BiTEs from the Edmonston B vaccine strain to target two model antigens...

Malaria is caused by Apicomplexa protozoans from the Plasmodium genus entering the bloodstream of humans and animals through the bite of the female mosquitoes. The annotation of the Plasmodium vivax genome revealed a putative RNA binding protein (apiRBP) that was predicted to be trafficked into the apicoplast, a plastid organelle unique to Apicomplexa protozoans. Although a 3D structural model of the apiRBP corresponds to a noncanonical RNA recognition motif with an additional C-terminal α-helix (α3), preliminary protein production trials were nevertheless unsuccessful...

Zikavirus (ZV) is a flavivirus transmitted by Aedes mosquitoes' bites. Sexual transmission is possible. Common ZV infection is asymptomatic or associates flu-like signs. Guillain-Barre syndrome following ZV infection is rare. Foetal infection, during the first trimester of pregnancy especially, can lead to severe neurological troubles. Diagnosis relies on blood and urine RT-PCR during the acute phase, and serology later in the disease. ELISA assays false positives are reported among patients infected with another flavivirus, whereas sero-neutralization is more specific...

The canine variant of the rabies virus has been eliminated in the United States. Among the public and many healthcare providers, however, dog bites are still associated with risk for rabies transmission. This study examined the risk of rabies in biting dogs and the use of rabies post-exposure prophylaxis (rPEP) for dog bite victims in Tennessee. The study included a retrospective analysis of laboratory testing requisitions for dogs from 2002 to 2016, collection of clinical data on confirmed rabies-positive dogs from 2008 to 2016 and analysis of hospital discharge data for rPEP from 2007 to 2014...
