Foreign body ingestion due to detachment of pill dispenser tips in cats: a retrospective study of 13 cases.

OBJECTIVES: The aim of this study was to evaluate and describe 13 cases in which a pet piller broke during the administration of medication, and the tip was accidentally ingested by the cat. METHODS: A total of 15 presentations to the clinic were identified in a private practice database involving 13 cats in which the silicone tip broke. Two of these cats ingested foreign bodies on two separate occasions. Routine radiographic examination enabled the identification of silicone tips in all animals. On 2/15 occasions, the cats did not receive an emetic drug. Intramuscular xylazine (0.2 mg/kg) and dexmedetomidine (6 µg/kg) were administered to 12/15 and 1/15 cats, respectively. RESULTS: The cats were aged 3-17 years (mean age 11.00 ± 4.35 years). Vomiting occurred in 13 cats that received alpha-2 adrenoceptor agonists, although the silicone tip was recovered in only five occurrences. In 9/15 occurrences, endoscopy was performed under general inhalation anesthesia, and the silicone tip was successfully removed. Natural elimination occurred in only one case. CONCLUSIONS AND RELEVANCE: The use of pet pillers with detachable silicone tips increases the risk of accidental foreign body ingestion by animals. Therefore, guidelines regarding safety standards for manufacturing would be beneficial. No cat in this series developed clinical signs related to the ingestion of the piller tip, probably because of the quick presentation by the owners and early intervention, including endoscopic retrieval. Surgical intervention was not required in any case, including one in which the foreign body was lodged within the small intestine before being passed naturally by the cat.

Evaluation of the S-locus in Prunus domestica, characterization, phylogeny and 3D modelling.

Self-compatibility has become the primary objective of most prune (Prunus domestica) breeding programs in order to avoid the problems related to the gametophytic self-incompatibility (GSI) system present in this crop. GSI is typically under the control of a specific locus., known as the S-locus., which contains at least two genes. The first gene encodes glycoproteins with RNase activity in the pistils., and the second is an SFB gene expressed in the pollen. There is limited information on genetics of SI/SC in prune and in comparison., with other Prunus species, cloning., sequencing and discovery of different S-alleles is very scarce. Clear information about S-alleles can be used for molecular identification and characterization of the S-haplotypes. We determined the S-alleles of 36 cultivars and selections using primers that revealed 17 new alleles. In addition, our study describes for the first time the association and design of a molecular marker for self-compatibility in P. domestica. Our phylogenetic tree showed that the S-alleles are spread across the phylogeny, suggesting that like previous alleles detected in the Rosaceae., they were of trans-specific origin. We provide for the first time 3D models for the P. domestica SI RNase alleles as well as in other Prunus species, including P. salicina (Japanese plum), P. avium (cherry), P. armeniaca (apricot), P. cerasifera and P. spinosa.

Dynavision Normative Data for Healthy Adults: Reaction Test Program.

IMPORTANCE: Previous research has calculated normative data for the Dynavision D2 Visuomotor Training (D2) System among healthy athletes to understand concussion management, but to date no studies have identified the norms for healthy adults over a large age range (18-80 yr) for physical response speed. OBJECTIVE: To provide normative data for the D2 for physical response speed in adults ages 18-80 yr. DESIGN: Cross-sectional, descriptive study to obtain normative data on physical response speed using the D2 for adults in age categories 18-40, 41-60, and 61-80 yr. SETTING: Genesis Physical Therapy and Wellness Center, a Midwestern outpatient hospital-based therapy center. PARTICIPANTS: Three hundred adults, stratified into three different age categories. Normal standards with quartiles were identified for each age and sex category. OUTCOMES AND MEASURES: Multiple regression model of the inverse response times. RESULTS: The results showed a significant difference in physical response speed between men and women and between the different age groups. Women in all age categories were slower than men. Physical response speed increased with age in both sexes, but each had significantly different age and sex main effects (p < .0005). CONCLUSIONS AND RELEVANCE: Occupational therapy practitioners can use the normative standards identified in this study in their assessment of clients with visual and cognitive deficits after a brain injury, stroke, or other neurologic pathology. WHAT THIS ARTICLE ADDS: This study's results can be added to the battery of other common evaluation measures that occupational therapists use to evaluate visual and cognitive deficits after neurological impairments.

Electrocutions in free-living black-tufted marmosets (Callithrix penicillata) in anthropogenic environments in the Federal District and surrounding areas, Brazil.

Shrinking natural habitats exposes some non-human primates to the risk of accidents associated with electrical transmission lines. We examined dead marmosets (Callithrix penicillata) collected in the region from January 2015 to April 2018 to determine the animals' cause of death and for electrocuted animals we examined the locations the animals had died as well as the configuration of the power lines at these sites. We also recorded the sex of the animal, the body region affected, and characteristics of the injuries. We diagnosed electrocutions in 11% (n = 34) of the marmosets studied. Most of the affected animals were male (n = 22) with single or double sites of injury on the limbs. Animals were injured in urban (n = 26) and peri-urban (n = 8) areas on lower-voltage alternate current lines, and we detected no seasonality or hotspots of electrocution. Our findings suggest that movement along transmission lines composed of bundled conductors is a major factor in electrocutions of marmosets in the Federal District and surrounding areas. The planning of electrical power grid infrastructure should consider arboreal primates to prevent electrocutions.

Genetic characterization of worldwide Prunus domestica (plum) germplasm using sequence-based genotyping.

Prunus domestica commonly known as European plum is a hexaploid fruit tree species cultivated around the world. Locally it is used for fresh consumption, in jams or jellies, and the production of spirits while commercially the fruit is primarily sold dried (prunes). Despite its agricultural importance and long history of cultivation, many questions remain about the origin of this species, the relationships among its many pomological types, and its underlying genetics. Here, we used a sequence-based genotyping approach to characterize worldwide plum germplasm including the potential progenitor Eurasian plum species. Analysis of 405 DNA samples established a set of four clades consistent with the pomological groups Greengages, Mirabelles, European plums, and d'Agen (French) prune plums. A number of cultivars from each clade were identified as likely clonal selections, particularly among the "French" type prune germplasm that is widely cultivated today. Overall, there was relatively low genetic diversity across all cultivated plums suggesting they have been largely inbred and/or derived from a limited number of founders. The results agree with P. domestica having originated as an interspecific hybrid of a diploid P. cerasifera and a tetraploid P. spinosa that itself may have been an interspecific hybrid of P. cerasifera and an unknown Eurasian plum species. The low genetic diversity and lack of true wild-types coupled with the known cultivation history of Eurasian plums imply that P. domestica may have been a product of inter-specific cross breeding and artificial selection by early agrarian Eurasian societies.

Practical considerations on performing and analyzing CLIP-seq experiments to identify transcriptomic-wide RNA-protein interactions.

RNA-binding proteins are important players in post-transcriptional regulation, such as modulating mRNA splicing, translation, and degradation under diverse biological settings. Identifying and characterizing the RNA substrates is a critical step in deciphering the function and molecular mechanisms of the target RNA-binding proteins. High-throughput sequencing of the RNA fragments isolated by crosslinking immunoprecipitation (CLIP-seq) is one of the standard techniques to identify the in vivo transcriptome-wide binding sites of the target RNA-binding protein. This method is widely used in functional and mechanistic characterizations of RNA-binding proteins. In this review, we provide several practical considerations on performing and analyzing CLIP-seq experiments. Particularly, we focus on how to perform CLIP-seq experiments on endogenous RNA-binding proteins. In addition, we provide a practical summary on how to choose and use computational pipelines from an increasing number of computational methods and packages that are available for analyzing the sequencing datasets from the CLIP-seq experiments. We hope these practical considerations will facilitate experimental biologists in performing and analyzing CLIP-seq experiment to obtain biologically relevant mechanistic insights.

Assessment of Time to Hospital Encounter after an Initial Hospitalization for Heart Failure: Results from a Tertiary Medical Center.

BACKGROUND: Hospital inpatient readmissions for patients admitted initially with the primary diagnosis of heart failure (HF) can be as high as 20-25% within 30 days of discharge. This, however, does not include admissions for observations or emergency department (ED) visits within the same time frame and does not show a time-dependent hospital encounter following discharge after an index admission. We present data on time-dependent hospital encounter of HF patients discharged after an index admission for a primary diagnosis of HF. METHODS: The study recruited patients from 2 hospitals within the same health system. 500 consecutive admissions with the ICD diagnosis of HF were reviewed by inclusion and exclusion screening criteria. The 166 eligible remaining patients were tracked for post hospital discharge encounters consisting of hospital admissions, observation stays, and ED visits. Only those with a primary diagnosis of heart failure were included. Demographics were recorded on all patients. Days until hospital inpatient readmissions or hospital encounters were displayed in Kaplan-Meier plots. RESULTS: A total of 166 patients met inclusion criteria (mean age 79.3 years, males 54%). For the first 90 days following the index admission, there were a total of 287 follow-up visits (1.7 per patient), 1158 total hospitalization days (2.6 per visit, 7.0 per patient, and 8.6 per 100 days at risk), and 21 deaths (12.7%). At 30 days, 25% and 52% of patients had an inpatient readmission or a hospital encounter, respectively. The median time to inpatient readmission was 117 days and to hospital encounter was 27 days. CONCLUSION: Time-dependent excess days in acute care (unplanned inpatient admission, outpatient observation, and ED visit) rather than 30-day hospital inpatient readmission rate is a more realistic measure of the intensity of care required for HF patients after index admission.

CO2 sequestration by ureolytic microbial consortia through microbially-induced calcite precipitation.

Urea is an abundant nitrogen-containing compound found in urine of mammals and widely used in fertilizers. This compound is part of the nitrogen biogeochemical cycle and is easily biodegraded by ureolytic microorganisms that have the urease enzyme. Previous studies, with ureolytic isolates, have shown that some ureolytic microorganisms are able to sequester CO2 through a process called microbially-induced calcium carbonate precipitation. The present study investigates 15 ureolytic consortia obtained from the "Pamukkale travertines" and the "Cave Without A Name" using different growth media to identify the possible bacterial genera responsible for CO2 sequestration through the microbially-induced calcite precipitation (MICP). The community structure and diversity were determined by deep-sequencing. The results showed that all consortia presented varying CO2 sequestration capabilities and MICP rates. The CO2 sequestration varied between 0 and 86.4%, and it depended largely on the community structure, as well as on pH. Consortia with predominance of Comamonas, Plesiomonas and Oxalobacter presented reduced CO2 sequestration. On the other hand, consortia dominated by Sporosarcina, Sphingobacterium, Stenotrophomonas, Acinetobacter, and Elizabethkingia showed higher rates of CO2 uptake in the serum bottle headspace.

Microbial monitoring of crewed habitats in space-current status and future perspectives.

Previous space research conducted during short-term flight experiments and long-term environmental monitoring on board orbiting space stations suggests that the relationship between humans and microbes is altered in the crewed habitat in space. Both human physiology and microbial communities adapt to spaceflight. Microbial monitoring is critical to crew safety in long-duration space habitation and the sustained operation of life support systems on space transit vehicles, space stations, and surface habitats. To address this critical need, space agencies including NASA (National Aeronautics and Space Administration), ESA (European Space Agency), and JAXA (Japan Aerospace Exploration Agency) are working together to develop and implement specific measures to monitor, control, and counteract biological contamination in closed-environment systems. In this review, the current status of microbial monitoring conducted in the International Space Station (ISS) as well as the results of recent microbial spaceflight experiments have been summarized and future perspectives are discussed.

Developing web-based training for public health practitioners: what can we learn from a review of five disciplines?

During a time when governmental funding, resources and staff are decreasing and travel restrictions are increasing, attention to efficient methods of public health workforce training is essential. A literature review was conducted to inform the development and delivery of web-based trainings for public health practitioners. Literature was gathered and summarized from five disciplines: Information Technology, Health, Education, Business and Communications, following five research themes: benefits, barriers, retention, promotion and evaluation. As a result, a total of 138 articles relevant to web-based training design and implementation were identified. Key recommendations emerged, including the need to conduct formative research and evaluation, provide clear design and layout, concise content, interactivity, technical support, marketing and promotion and incentives. We conclude that there is limited application of web-based training in public health. This review offers an opportunity to learn from other disciplines. Web-based training methods may prove to be a key training strategy for reaching our public health workforce in the environment of limited resources.

Evaluation of microorganisms cultured from injured and repressed tissue regeneration sites in endangered giant aquatic Ozark Hellbender salamanders.

Investigation into the causes underlying the rapid, global amphibian decline provides critical insight into the effects of changing ecosystems. Hypothesized and confirmed links between amphibian declines, disease, and environmental changes are increasingly represented in published literature. However, there are few long-term amphibian studies that include data on population size, abnormality/injury rates, disease, and habitat variables to adequately assess changes through time. We cultured and identified microorganisms isolated from abnormal/injured and repressed tissue regeneration sites of the endangered Ozark Hellbender, Cryptobranchus alleganiensis bishopi, to discover potential causative agents responsible for their significant decline in health and population. This organism and our study site were chosen because the population and habitat of C. a. bishopi have been intensively studied from 1969-2009, and the abnormality/injury rate and apparent lack of regeneration were established. Although many bacterial and fungal isolates recovered were common environmental organisms, several opportunistic pathogens were identified in association with only the injured tissues of C.a. bishopi. Bacterial isolates included Aeromonas hydrophila, a known amphibian pathogen, Granulicetella adiacens, Gordonai terrae, Stenotrophomonas maltophilia, Aerococcus viridans, Streptococcus pneumoniae and a variety of Pseudomonads, including Pseudomonas aeruginosa, P. stutzeri, and P. alcaligenes. Fungal isolates included species in the genera Penicillium, Acremonium, Cladosporium, Curvularia, Fusarium, Streptomycetes, and the Class Hyphomycetes. Many of the opportunistic pathogens identified are known to form biofilms. Lack of isolation of the same organism from all wounds suggests that the etiological agent responsible for the damage to C. a. bishopi may not be a single organism. To our knowledge, this is the first study to profile the external microbial consortia cultured from a Cryptobranchid salamander. The incidence of abnormalities/injury and retarded regeneration in C. a. bishopi may have many contributing factors including disease and habitat degradation. Results from this study may provide insight into other amphibian population declines.

Induction of attachment-independent biofilm formation and repression of Hfq expression by low-fluid-shear culture of Staphylococcus aureus.

The opportunistic pathogen Staphylococcus aureus encounters a wide variety of fluid shear levels within the human host, and they may play a key role in dictating whether this organism adopts a commensal interaction with the host or transitions to cause disease. By using rotating-wall vessel bioreactors to create a physiologically relevant, low-fluid-shear environment, S. aureus was evaluated for cellular responses that could impact its colonization and virulence. S. aureus cells grown in a low-fluid-shear environment initiated a novel attachment-independent biofilm phenotype and were completely encased in extracellular polymeric substances. Compared to controls, low-shear-cultured cells displayed slower growth and repressed virulence characteristics, including decreased carotenoid production, increased susceptibility to oxidative stress, and reduced survival in whole blood. Transcriptional whole-genome microarray profiling suggested alterations in metabolic pathways. Further genetic expression analysis revealed downregulation of the RNA chaperone Hfq, which parallels low-fluid-shear responses of certain Gram-negative organisms. This is the first study to report an Hfq association with fluid shear in a Gram-positive organism, suggesting an evolutionarily conserved response to fluid shear among structurally diverse prokaryotes. Collectively, our results suggest S. aureus responds to a low-fluid-shear environment by initiating a biofilm/colonization phenotype with diminished virulence characteristics, which could lead to insight into key factors influencing the divergence between infection and colonization during the initial host-pathogen interaction.

Accelerating evidence reviews and broadening evidence standards to identify effective, promising, and emerging policy and environmental strategies for prevention of childhood obesity.

The childhood obesity epidemic has stimulated the emergence of many policy and environmental strategies to increase healthy eating and active living, with relatively few research recommendations identifying the most effective and generalizable strategies. Yet, local, state, and national decision makers have an urgent need to take action, particularly with respect to lower-income and racial and ethnic populations at greatest risk. With the surge of promising and emerging policy and environmental strategies, this review provides a framework, criteria, and process modeled from existing expert classification systems to assess the strength of evidence for these strategies. Likewise, this review highlights evidence gaps and ways to increase the types and amount of evidence available to inform policy and environmental strategies. These priorities include documenting independent and interdependent effects, determining applicability to different populations and settings, assessing implementation fidelity and feasibility, identifying cumulative benefits and costs, ascertaining impacts on health equity, and tracking sustainability.

A diabetes self-management program designed for urban American Indians.

BACKGROUND: Although the American Indian population has a disproportionately high rate of type 2 diabetes, little has been written about culturally sensitive self-management programs in this population. CONTEXT: Community and clinic partners worked together to identify barriers to diabetes self-management and to provide activities and services as part of a holistic approach to diabetes self-management, called the Full Circle Diabetes Program. METHODS: The program activities and services addressed 4 components of holistic health: body, spirit, mind, and emotion. Seven types of activities or services were available to help participants improve diabetes self-management; these included exercise classes, educational classes, and talking circles. CONSEQUENCES: Ninety-eight percent of program enrollees participated in at least 1 activity, and two-thirds participated in 2 or more activities. Program participation resulted in a significant improvement in knowledge of resources for managing diabetes. INTERPRETATION: The Full Circle Diabetes Program developed and implemented culturally relevant resources and supports for diabetes self-management in an American Indian population. Lessons learned included that a holistic approach to diabetes self-management, community participation, and stakeholder partnerships are needed for a successful program.

Isolation of long-lived mutants in Caenorhabditis elegans using selection for resistance to juglone.

The accumulation of molecular damage from attack by reactive oxygen species is one cause of aging. Therefore, some mutant organisms showing increased resistance to reactive oxygen species should live longer. We show that selection for Caenorhabditis elegans mutants that are resistant to juglone, a reactive oxygen species-generating compound, leads to the identification of long-lived mutants. Indeed, four of six resistant mutants isolated were also long-lived. This study illustrates once more the strong relationship between oxidative stress and the aging processes.

Functional analysis of the glutathione S-transferase 3 from Onchocerca volvulus (Ov-GST-3): a parasite GST confers increased resistance to oxidative stress in Caenorhabditis elegans.

This study examined the genomic organisation of the coding region of the glutathione S-transferase 3 (Ov-GST-3) from the human parasitic nematode Onchocerca volvulus; alternative splicing leads to three different transcripts (Ov-GST-3/1; Ov-GST-3/2 and Ov-GST-3/3). Since the expression of Ov-GST-3 is inducible by oxidative stress, it is assumed that it is involved in the defense against reactive oxygen species (ROS) resulting from cellular metabolism. Furthermore, we suggest that Ov-GST-3 plays an important role in the protection of the parasite against ROS derived from the host's immune system. To experimentally investigate these speculations, we generated Caenorhabditis elegans lines transgenic for Ov-GST-3 (AK1) and examined their resistance to artificially generated ROS. The AK1 worms (extrachromosomal and integrated lines) were found to be much more resistant to internal (juglone) and external (hypoxanthine/xanthine oxidase) oxidative stress than wild-type C.elegans worms. RNA interference experiments targeted to the Ov-GST-3 transcripts resulted in decreased resistance, confirming that this effect is due to the transgenic expression of Ov-GST-3. These results clearly demonstrate that the Ov-GST-3 gene confers an increased resistance to oxidative stress. This study also shows the applicability of C.elegans as a model organism for the functional characterization of genes from (parasitic) nematode species which are not accessible to genetic manipulations.
