CHEMICAL IMMOBILIZATION OF HELICOPTER-CAPTURED ELK (CERVUS CANADENSIS) AND SURVIVAL OF ELK CALVES IN SOUTHEASTERN KENTUCKY

Safe and effective chemical immobilization is critical to minimize stress and risk of injury when capturing free-ranging, wild ungulates. Many traditionally favored high potency opioids have been phased out or become unavailable because of increased regulations, leading to the development of two pre-mixed combination drugs, butorphanol-azaperone-medetomidine (BAM) and nalbuphine-medetomidine-azaperone (NalMed-A). Both drugs have been used to chemically immobilize ungulates, but their efficacy has not been documented in elk captured and transported via helicopter. During 2020 – 2022, we chemically immobilized helicopter-captured female elk (Cervus canadensis) with a single IM-injection of BAM (n = 41) or NalMed-A (n = 78) and documented onset of action and physiological responses including heart rate, respiration, body temperature, and blood oxygen saturation. Mean induction times were 8.34 ± 0.03 minutes for BAM and 8.78 ± 0.08 minutes for NalMed-A. We reversed sedation with atipamezole (IM/IV) and naltrexone (IM), with comparable mean reversal times of 4.56 ± 0.09 and 4.14 ± 0.05 minutes for BAM and NalMed-A, respectively. All physiological responses decreased with induction of either drug, whereas post-induction heart rate and respiration were stable. During these captures, we checked sedated female elk for signs of pregnancy to prepare for a 3-year calf survival study using vaginal implant transmitters to locate newborn calves across Kentucky’s Elk Restoration Zone. During 2020 – 2022, we captured 81 elk neonates and monitored their survival to one year of age or until a mortality occurred, allowing us to estimate elk calf survival for three survival periods (neonatal, summer, and annual), determine cause-specific mortality, and elucidate how maternal characteristics, morphometrics, health metrics, and weather conditions influence survival. Because survival monitoring was not yet completed for calves captured in 2022, we only reported mean survival ranges for calves captured in 2020 and 2021. During these years, we documented 14 mortalities and 6 unknown fates, which were censored. The top proximate cause of mortality was predation or suspect predation by black bears and coyotes (n = 7), followed by trauma (n = 2), and emaciation or abandonment (n = 2). Mean neonatal survival ranged from 0.822 (SE ± 0.057) to 0.844 (SE ± 0.054) and was influenced by total precipitation during the first week of life. Mean summer survival ranged from 0.730 (SE ± 0.067) to 0.772 (SE ± 0.064) and was influenced by total precipitation during the first week of life and femur length. Lastly, mean annual survival ranged from 0.556 (SE ± 0.074) to 0.681 (SE ± 0.071) and was only influenced by femur length. No maternal characteristics and health metrics appeared to influence survival during any period. Although our mean annual survival range is lower than the survival rates previously reported in Kentucky and other eastern elk populations, it is likely more representative of Kentucky’s fully established and stabilized elk herd 20 years after the completion the state’s reintroduction efforts

Content and Quality of Information Concerning Reference and Instruction Programs in Community Colleges as Evidenced by the Library Websites

This study describes an evaluation of forty U.S. community college library websites' reference and instruction programs in relation to the needs of distance education patrons. The evaluation was conducted in order to determine the type and quality of information provided about these services as well as the level of adherence to RUSA and ACRL guidelines and standards. With community college distance enrollment on an upward trend, their libraries must increase their distance learning library services in order to meet the needs of this growing segment of their patron population. The findings of this research show that the level of service currently offered by most community college libraries is not sufficient to meet the needs of distance education students. This paper suggests improvements for existing distance learning library websites and topic for further research

Examining the Effect of Physician Language on Physician Impressions

Previous research provides evidence that stigma can be perpetuated through language with consequences for well-being and quality of care. For example, providers who use stigmatizing language transmit bias toward patients with implications for care provided by other healthcare professionals. The current work extends upon this research by investigating perceptions of physicians who use stigmatizing or humanizing language. The current work sought to document the negative consequences of providers’ indelicate language on impressions of the provider, thereby motivating thoughtful language choices. To this end, the current work experimentally manipulated the language (stigmatizing, identity-first and destigmatizing, person-first) that hypothetical providers used to describe individuals with substance use disorder and examined participants’ judgments of the providers (likeability and positive behavioral intentions). We predicted that the provider using stigmatizing, identity-first language would elicit more negative responses than the provider using destigmatizing, person-first language. However, the results provided no support for this hypothesis; instead, we observed only an effect of the vignette content: participants had more positive perceptions of the physician who spoke first, compared to the physician who spoke second. Although the current work did not observe significant effects of language, past work indicates the importance of empathy, warmth, and respect from providers for patient well-being and outcome. We suggest directions for improving upon the current study, as well as possible topics for future research that may aid in understanding these important antecedents of inclusive and successful patient-physician interactions

Islet autoantibody profiles associated with higher diabetes risk in Lithuanian compared with English schoolchildren

Over a 15 year period, the incidence of type 1 diabetes has doubled in Lithuania, whilst increasing by a third in England, however England still has the higher incidence. Analysis of sera collected from non-diabetic schoolchildren from Lithuania and England more than 20 years ago showed a similar number of multiple autoantibody positive schoolchildren between the populations, but a higher prevalence of islet antigen-2 autoantibodies (IA-2A) in English schoolchildren. We aimed to use recently developed, more specific islet autoantibody tests, to characterise differences in humoral autoimmunity between these two general population cohorts in greater detail. Samples from 88 Lithuanian and 133 English schoolchildren previously found islet autoantibody positive were selected for measurement of additional islet autoantibodies by radioimmunoassay. Samples were tested for autoantibodies to zinc transporter 8 (ZnT8A), GAD(96-585), the protein tyrosine phosphatase region of islet antigen-2 (PTPA), and the related IA-2βA while autoantibodies to IA-2A were re-assayed using the current harmonized method. IA-2 related autoantibodies PTPA (0.13% vs. 0.45%, p=0.027) and IA-2βA (0% vs. 0.35%, p<0.001), but not IA-2A measured using the harmonized method, were less common in Lithuanian compared to English schoolchildren. Lithuanian schoolchildren who were islet autoantibody positive, were positive for fewer biochemical autoantibodies compared with English schoolchildren (p=0.043). Background rates of islet autoimmunity in childhood differ subtly between countries which have different incidences of type 1 diabetes. The optimal screening strategy (age and combination of markers) for detection of islet autoimmunity may vary between countries dependent on the pattern of autoantibodies found in the general population

Secondary prevention and cognitive function after stroke: a study protocol for a 5-year follow-up of the ASPIRE-S cohort

Introduction Cognitive impairment is common following stroke and can increase disability and levels of dependency of patients, potentially leading to greater burden on carers and the healthcare system. Effective cardiovascular risk factor control through secondary preventive medications may reduce the risk of cognitive decline. However, adherence to medications is often poor and can be adversely affected by cognitive deficits. Suboptimal medication adherence negatively impacts secondary prevention targets, increasing the risk of recurrent stroke and further cognitive decline. The aim of this study is to profile cognitive function and secondary prevention, including adherence to secondary preventive medications and healthcare usage, 5 years post-stroke. The prospective associations between cognition, cardiovascular risk factors, adherence to secondary preventive medications, and rates of recurrent stroke or other cardiovascular events will also be explored. Methods and analysis This is a 5-year follow-up of a prospective study of the Action on Secondary Prevention Interventions and Rehabilitation in Stroke (ASPIRE-S) cohort of patients with stroke. This cohort will have a detailed assessment of cognitive function, adherence to secondary preventive medications and cardiovascular risk factor control. Ethics and dissemination Ethical approval for this study was granted by the Research Ethics Committees at Beaumont Hospital, Dublin and Connolly Hospital, Dublin, Mater Misericordiae University Hospital, Dublin, and the Royal College of Surgeons in Ireland. Findings will be disseminated through presentations and peer-reviewed publications

Pass This Message Along: Self-edited Email Messages Promoting Colon Cancer Screening among Friends and Family

Encouraging communication within a social network may promote uptake of desired medical services or health behaviors. Little is known about the use of this approach to promote colorectal cancer (CRC) screening. We conducted in-person interviews with 438 insured adults ages 42-73 in Massachusetts, Hawaii, and Georgia. Participants were shown a sample message in which the sender shares that he has completed a colonoscopy and urges the recipient to discuss CRC screening with a doctor. We asked participants to edit the message to create one they would be willing to send to friends and family via email or postcard. Changes to the message were recorded. Edited text was analyzed for content and concordance with original message. The majority of participants (61.6%) modified the message; 14.2% added to or reframed the existing personalizing words (e.g. adding ‘because I love you’), 10.3% added urgency to the message (e.g. “please don’t delay”) and 8% added reassurance (e.g. “It’s really not that bad.”) Almost one in five (18.3%) deleted a negatively framed sentence on colon cancer risks. In 5.7% of cases, the meaning of at least one sentence was changed but only 2.7% created messages with factual inaccuracies. Modifiable messages transmitted within a social network offer a way for screened individuals to promote CRC screening. Further study is needed to identify the optimal combination of user-generated content and pre-written text, allowing for creation of messages that are acceptable to senders, persuasive and factually accurate

Using Low-Fix Rate GPS Telemetry to Expand Estimates of Ungulate Reproductive Success

Background Population parameters such as reproductive success are critical for sustainably managing ungulate populations, however obtaining these data is often difficult, expensive, and invasive. Movement-based methods that leverage Global Positioning System (GPS) relocation data to identify parturition offer an alternative to more invasive techniques such as vaginal implant transmitters, but thus far have only been applied to relocation data with a relatively fine (one fix every  \u3c 8 h) temporal resolution. We employed a machine learning method to classify parturition/calf survival in cow elk in southeastern Kentucky, USA, using 13-h GPS relocation data and three simple movement metrics, training a random forest on cows that successfully reared their calf to a week old. Results We developed a decision rule based upon a predicted probability threshold across individual cow time series, accurately classifying 89.5% (51/57) of cows with a known reproductive status. When used to infer status of cows whose reproductive outcome was unknown, we classified 48.6% (21/38) as successful, compared to 85.1% (40/47) of known-status cows. Conclusions While our approach was limited primarily by fix acquisition success, we demonstrated that coarse collar fix rates did not limit inference if appropriate movement metrics are chosen. Movement-based methods for determining parturition in ungulates may allow wildlife managers to extract more vital rate information from GPS collars even if technology and related data quality are constrained by cost

The Association Between Low Health Literacy and Attitudes, Behaviors and Knowledge that Influence Engagement in Cancer Screening and Prevention Activities

Background: Health literacy is a complex, multifaceted phenomenon. While health literacy has historically been measured using instruments that assess reading and numeracy, comprehension of spoken information is also important. The purpose of this study was to identify adults with low health literacy using a multi-dimensional assessment of health literacy and to explore whether low health literacy was associated with variables likely to affect engagement in cancer prevention and screening activities. Methods: A random sample of English speaking adults aged 40-70 were invited to participate from: Kaiser Permanente Georgia, Hawaii, Colorado, and Fallon Community Health Plan Massachusetts. The Cancer Message Literacy Test-Listening, the Cancer Message Literacy Test-Reading, and the Lipkus Numeracy Scale were all used to assess aspects of health literacy. We also assessed self-efficacy, provider trust, and fatalism. Participants self-reported demographic data, health seeking behavior, and media use. Results: Out of 1074 adults, 48% were white, 73% were educated beyond high school, and 53% rated their health as very good or excellent. Compared to others, adults with low health literacy were more likely to avoid physician visits (p \u3c .001), more fatalistic about cancer (p Conclusions: In this population of insured adults, we identified differences among adults with low health literacy which may impact their engagement in cancer prevention and screening activities. These findings have important implications for health care interactions and public health communication. Understanding the reasons for these beliefs and behaviors may suggest ways to target and tailor communication for this vulnerable population

Identification of Bacillus anthracis specific chromosomal sequences by suppressive subtractive hybridization

BACKGROUND: Bacillus anthracis, Bacillus thuringiensis and Bacillus cereus are closely related members of the B. cereus-group of bacilli. Suppressive subtractive hybridization (SSH) was used to identify specific chromosomal sequences unique to B. anthracis. RESULTS: Two SSH libraries were generated. Genomic DNA from plasmid-cured B. anthracis was used as the tester DNA in both libraries, while genomic DNA from either B. cereus or B. thuringiensis served as the driver DNA. Progressive screening of the libraries by colony filter and Southern blot analyses identified 29 different clones that were specific for the B. anthracis chromosome relative not only to the respective driver DNAs, but also to seven other different strains of B. cereus and B. thuringiensis included in the process. The nucleotide sequences of the clones were compared with those found in genomic databases, revealing that over half of the clones were located into 2 regions on the B. anthracis chromosome. CONCLUSIONS: Genes encoding potential cell wall synthesis proteins dominated one region, while bacteriophage-related sequences dominated the other region. The latter supports the hypothesis that acquisition of these bacteriophage sequences occurred during or after speciation of B. anthracis relative to B. cereus and B. thuringiensis. This study provides insight into the chromosomal differences between B. anthracis and its closest phylogenetic relatives
