An evaluation of Northwest Arkansas elementary school nurses\u27 perceptions of their role in the management and prevention of obesity

The purpose of this study was to investigate the roles and perceptions of elementary school nurses in the management and prevention of childhood obesity within the school environment. An emailed online survey was distributed to school nurses of 35 elementary schools located in Washington County in Northwest Arkansas. The survey used for this study contained 42 questions and was an adaptation of the Minnesota School Nurse Survey, which was developed by Dr. Martha Y. Kubik. The study sample consisted of all school nurses employed by the Elkins School District, Farmington School District, Fayetteville School District, Greenland School District, Lincoln School District, Prairie Grove School District, Springdale School District, and West Fork School District. The number of complete survey responses was seventeen. Data was analyzed using frequency distribution to examine the prevalence of key variables. Interestingly enough, the majority of nurses surveyed agreed that schools should provide annual assessments of students’ weight, height, and body mass index and make that information available to parents, but disagreed that the school nurse has adequate time to supervise and monitor obesity prevention efforts at school. Additionally, since the majority of nurses surveyed disagreed that the school nurse is prepared to supervise and monitor obesity prevention efforts at school, future focus needs to include increased professional development about measures in which the school nurse can participate in to increase obesity management and prevention and increased time and support from the school and healthcare professionals

Introducing the tablet-based Oxford Cognitive Screen-Plus (OCS-Plus) as an assessment tool for subtle cognitive impairments

Here, we present the Oxford Cognitive Screen-Plus, a computerised tablet-based screen designed to briefly assess domain-general cognition and provide more fine-grained measures of memory and executive function. The OCS-Plus was designed to sensitively screen for cognitive impairments and provide a differentiation between memory and executive deficits. The OCS-Plus contains 10 subtasks and requires on average 24 min to complete. In this study, 320 neurologically healthy ageing participants (age M = 62.66, SD = 13.75) from three sites completed the OCS-Plus. The convergent validity of this assessment was established in comparison to the ACE-R, CERAD and Rey-Osterrieth. Divergent validity was established through comparison with the BDI and tests measuring divergent cognitive domains. Internal consistency of each subtask was evaluated, and test-retest reliability was determined. We established the normative impairment cut-offs for each of the subtasks. Predicted convergent and divergent validity was found, high internal consistency for most measures was also found with the exception of restricted range tasks, as well as strong test-retest reliability, which provided evidence of test stability. Further research demonstrating the use and validity of the OCS-Plus in various clinical populations is required. The OCS-Plus is presented as a standardised cognitive assessment tool, normed and validated in a sample of neurologically healthy participants. The OCS-Plus will be available as an Android App and provides an automated report of domain-general cognitive impairments in executive attention and memory

Monitoring Temporal Changes in SARS-CoV-2 Spike Antibody Levels and Variant-Specific Risk for Infection, Dominican Republic, March 2021-August 2022

To assess changes in SARS-CoV-2 spike binding antibody prevalence in the Dominican Republic and implications for immunologic protection against variants of concern, we prospectively enrolled 2,300 patients with undifferentiated febrile illnesses in a study during March 2021-August 2022. We tested serum samples for spike antibodies and tested nasopharyngeal samples for acute SARS-CoV-2 infection using a reverse transcription PCR nucleic acid amplification test. Geometric mean spike antibody titers increased from 6.6 (95% CI 5.1-8.7) binding antibody units (BAU)/mL during March-June 2021 to 1,332 (95% CI 1,055-1,682) BAU/mL during May-August 2022. Multivariable binomial odds ratios for acute infection were 0.55 (95% CI 0.40-0.74), 0.38 (95% CI 0.27-0.55), and 0.27 (95% CI 0.18-0.40) for the second, third, and fourth versus the first anti-spike quartile; findings were similar by viral strain. Combining serologic and virologic screening might enable monitoring of discrete population immunologic markers and their implications for emergent variant transmission

Gender, Sex, and Empire

The intersection of gender, sexuality, and race is a new area of exploration within the study of European imperialism. In this essay the author discusses such roles as white women’s implicit task of regulating the sexual boundaries between the ruling classes and the indigenous populations during the 18th and 19th centuries. The focus of this exploration is primarily on British Africa and India, with other areas briefly touched upon.https://scholar.dominican.edu/cynthia-stokes-brown-books-personal-research/1154/thumbnail.jp

Cryptocandin, a potent antimycotic from the endophytic fungus Cryptosporiopsis cf. quercina.

A unique lipopeptide antimycotic, termed cryptocandin, is described from Cryptosporiopsis cf. quercina, an endophytic fungus. Cryptocandin, with a molecular mass of 1079 Da, contains equimolar amounts of 3,4-dihydroxyhomotyrosine, 4-hydroxyproline, threonine, glutamine, 3-hydroxy-4-hydroxymethylproline, 4,5-dihydroxyornithine and palmitic acid. Cryptocandin is chemically related to well-known antimycotics, the echinocandins and pneumocandins, which are produced by such fungi as Zalerion arboricola, Pezicula spp. and Aspergillus spp. Cryptocandin has minimal inhibitory concentration values of 0.03-0.07 microgram ml-1 against isolates of Candida albicans, Trichophyton mentagrophytes and Trichophyton rubrum. Cryptocandin is also active against a number of plant-pathogenic fungi including Sclerotinia sclerotiorum and Botrytis cinerea

Coronamycins, peptide antibiotics produced by a verticillate Streptomyces sp. (MSU-2110) endophytic on Monstera sp.

Coronamycin is a complex of novel peptide antibiotics with activity against pythiaceous fungi and the human fungal pathogen Cryptococcus neoformans. It is also active against the malarial parasite, Plasmodium falciparum, with an IC(50) of 9.0 ng ml(-1). Coronamycin is produced by a verticillate Streptomyces sp. isolated as an endophyte from an epiphytic vine, Monstera sp., found in the Manu region of the upper Amazon of Peru. Bioassay-guided fractionation of the fermentation broths of this endophyte on silica gel and HPLC chromatography yielded two principal, inseparable, peptides with masses of 1217.9 and 1203.8 Da. Three other minor, but related components, are also present in the preparation. Amino acid analysis of coronamycin revealed residues of component 1, component 2, methionine, tyrosine and leucine at a ratio of 2:2:1:1:3. Other compounds with antifungal activities are also produced by this endophytic streptomycete
