Understanding Cigarette Butt Littering Behavior on a Public Beach: A Case Study of Jekyll Island

Conservation of natural resources and promotion of family-friendly tourism activities are vital to Jekyll Island. As it is stated in the Jekyll Island Authority (JIA) Master Plan “Jekyll Island is a unique, state-owned barrier island that balances conserving and preserving natural, historic, and cultural resources with providing accessible, affordable recreation, vacation, and education opportunities for the people of Georgia and beyond” (Jekyll Island Authority, 2014b, p. 4). The JIA has reported approximately 1 million people visit the island annually (Jekyll Island Authority, 2015). As such, tourism is instrumental to Jekyll Island’s economy, and that tourism contributes to the overall economy of Glynn County. According to a report put out by Glynn County (2014) the unemployment rate in the county is consistently within one point of the rest of the state, primarily due to tourism

A Nursing Diagnosis Decision Aid Adoption Assessment

This study investigates the roles trust and bias may play in nursing information technology acceptance via a two-phase study.In phase one, the impact of user experience on levels of trust in and bias towards automated decision aids (ADAs) isassessed. In phase two, the impact of trust and bias on ADA adoption is explored using actual usage data. The resultsindicate that experienced nurses have higher levels of trust and positive bias towards automation; yet, novice nurses are morelikely to accept information from an ADA. Additionally, a parsimonious model incorporating trust, bias, experience, andADA adoption is proposed

Comprehensive identification of host modulators of HIV-1 replication using multiple orthologous RNAi reagents

RNAi screens have implicated hundreds of host proteins as HIV-1 dependency factors (HDFs). While informative, these early studies overlap poorly due to false positives and false negatives. To ameliorate these issues, we combined information from the existing HDF screens together with new screens performed with multiple orthologous RNAi reagents (MORR). In addition to being traditionally validated, the MORR screens and the historical HDF screens were quantitatively integrated by the adaptation of an established analysis program, RIGER, for the collective interpretation of each gene\u27s phenotypic significance. False positives were addressed by the removal of poorly expressed candidates through gene expression filtering, as well as with GESS, which identifies off-target effects. This workflow produced a quantitatively integrated network of genes that modulate HIV-1 replication. We further investigated the roles of GOLGI49, SEC13, and COG in HIV-1 replication. Collectively, the MORR-RIGER method minimized the caveats of RNAi screening and improved our understanding of HIV-1-host cell interactions

Leveraging telehealth supportive oncology services to combat COVID-19 isolation in breast cancer patients: A cancer center’s perspective

During the COVID-19 pandemic, breast cancer patient in-person visits were converted to telehealth visits. Given our concerns about increased isolation amongst breast cancer patients during the pandemic, and the deleterious effects of such isolation on patient outcomes, we investigated utilization rates of psycho-social services amongst newly diagnosed breast cancer patients at our institution. We explored visit platforms (telehealth versus in-person) and time points prior to and encompassing the early pandemic. Despite decreased new breast cancer visits, there was a greater than 2-fold increase in supportive oncology service encounters in breast cancer patients during COVID-19 suggesting increased need for psycho-oncology resources. While services had not been offered virtually prior to the pandemic, the majority of the supportive oncology visits were conducted via telehealth during the initial months (73%) and year (59%) of the pandemic. 89% of breast cancer patients accessing psycho-social services were in-state patients, and service utilization increased amongst rural and urban residents during the pandemic. Total numbers of rural patients receiving supportive oncology services remained low compared to numbers of urban patients, however, though virtual visits predominated. While the number of out-of-state patients accessing psycho-oncology services during the pandemic was low, there was a 5-fold increase in psycho-social service utilization in this group during the pandemic. The majority of these visits were in-person. Telehealth services can be used to extend psycho-social support to breast cancer patients and combat the experience of isolation exacerbated by the pandemic. Virtual visits can be further utilized to increase outreach to rural and out-of-state patients.

Accurate forest projections require long-term wood decay experiments because plant trait effects change through time.

Whether global change will drive changing forests from net carbon (C) sinks to sources relates to how quickly deadwood decomposes. Because complete wood mineralization takes years, most experiments focus on how traits, environments and decomposer communities interact as wood decay begins. Few experiments last long enough to test whether drivers change with decay rates through time, with unknown consequences for scaling short-term results up to long-term forest ecosystem projections. Using a 7 year experiment that captured complete mineralization among 21 temperate tree species, we demonstrate that trait effects fade with advancing decay. However, wood density and vessel diameter, which may influence permeability, control how decay rates change through time. Denser wood loses mass more slowly at first but more quickly with advancing decay, which resolves ambiguity about the after-life consequences of this key plant functional trait by demonstrating that its effect on decay depends on experiment duration and sampling frequency. Only long-term data and a time-varying model yielded accurate predictions of both mass loss in a concurrent experiment and naturally recruited deadwood structure in a 32-year-old forest plot. Given the importance of forests in the carbon cycle, and the pivotal role for wood decay, accurate ecosystem projections are critical and they require experiments that go beyond enumerating potential mechanisms by identifying the temporal scale for their effects

Cervical Cancer in Cameroon: A Three Pronged Approach to Increase Awareness, Vaccination, Screening and Treatment

Problem: Cameroon has a disproportionately high burden of cervical cancer due to low awareness that the disease is preventable with prophylactic vaccines, lack of screening and treatment of pre-cancerous lesions, and high prevalence of human immunodeficiency virus (HIV). Between 2007-2013, the Cameroon Baptist Convention Health Services (CBCHS) devised three programs to: (1) increase awareness about cervical cancer; (2) immunize girls aged 9-13 years against human papilloma virus (HPV); and (3) conduct cervical cancer screening and treatment. Approaches: In collaboration with clinicians and researchers at University of Massachusetts and Northeastern University, CBCHS conducted education programs about HPV vaccine and cervical cancer for parents, adolescents, health care workers, and community members. The HPV vaccination demonstration project was implemented in three settings: schools, healthcare facilities, and in communities. CBCHS conducted cervical cancer screening in six sites using a “see and treat approach”. Findings: Following approval by the Ministry of Health, CBCHS nurses educated girls, parents, and communities about HPV, cervical cancer, and HPV vaccine through multimedia coverage. A total of 6,851, 6,517 and 5,876 girls were immunized with first, second and third doses, respectively. Achieving an 84.6% 3-dose completion rate. Since 2007, 30,617 women have been screened with visual inspection with acetic acid and digital cervicography. Women with precancerous lesions were treated with cryotherapy or loop electrical excision procedure. Lesions suspicious for cancer were biopsied for histology. Of those screened, 3,015 (10%) self reported HIV-positivity, 19,837 (64%) were HIV-negative, and the HIV status of the remaining women was unreported (25%). The percentage of HIV infected women diagnosed with cancer was consistently higher than the percentage of HIV uninfected women diagnosed with cancer. Lessons Learned: The project demonstrated that, with adequate education of stakeholders, HPV vaccination and cervical cancer screening programs are acceptable and feasible methods to improve cervical cancer outcomes in Cameroon

Familial deletion 18p syndrome: case report

BACKGROUND: Deletion 18p is a frequent deletion syndrome characterized by dysmorphic features, growth deficiencies, and mental retardation with a poorer verbal performance. Until now, five families have been described with limited clinical description. We report transmission of deletion 18p from a mother to her two daughters and review the previous cases. CASE PRESENTATION: The proband is 12 years old and has short stature, dysmorphic features and moderate mental retardation. Her sister is 9 years old and also has short stature and similar dysmorphic features. Her cognitive performance is within the borderline to mild mental retardation range. The mother also presents short stature. Psychological evaluation showed moderate mental retardation. Chromosome analysis from the sisters and their mother revealed the same chromosomal deletion: 46, XX, del(18)(p11.2). Previous familial cases were consistent regarding the transmission of mental retardation. Our family differs in this regard with variable cognitive impairment and does not display poorer verbal than non-verbal abilities. An exclusive maternal transmission is observed throughout those families. Women with del(18p) are fertile and seem to have a normal miscarriage rate. CONCLUSION: Genetic counseling for these patients should take into account a greater range of cognitive outcome than previously reported

Symbiotic modeling: Linguistic Anthropology and the promise of chiasmus

Reflexive observations and observations of reflexivity: such agendas are by now standard practice in anthropology. Dynamic feedback loops between self and other, cause and effect, represented and representamen may no longer seem surprising; but, in spite of our enhanced awareness, little deliberate attention is devoted to modeling or grounding such phenomena. Attending to both linguistic and extra-linguistic modalities of chiasmus (the X figure), a group of anthropologists has recently embraced this challenge. Applied to contemporary problems in linguistic anthropology, chiasmus functions to highlight and enhance relationships of interdependence or symbiosis between contraries, including anthropology’s four fields, the nature of human being and facets of being human

Anti proliferative activity of ELACYT™ (CP-4055) in combination with cloretazine (VNP40101M), idarubicin, gemcitabine, irinotecan and topotecan in human leukemia and lymphoma cells

This study evaluated combination drug partners for CP-4055, the C18:1Δ9,trans unsaturated fatty acid ester of cytarabine in HL-60 and U937 cells. Growth inhibition was assessed by ATP assay and drug interaction by the combination index and three dimensional methods. Synergy was observed in HL-60 cells for simultaneous combinations of CP-4055 with gemcitabine, irinotecan and topotecan, while combinations with cloretazine (VNP40101M) and idarubicin were additive. In U937 cells, synergy was observed with gemcitabine and additivity for the other drugs. In HL-60, the IC50 concentration of CP-4055 could be reduced 10-fold and that of gemcitabine 3-fold in combination versus the agents alone, an interaction that was independent of drug sequence, ratio and exposure time. In contrast, interactions of CP-4055 with the topoisomerase inhibitors became antagonistic when the drugs were administered 24 h prior to CP-4055 and at certain drug ratios, particularly in U937 cells. In summary, CP-4055 produced additive to synergistic anti proliferative activity when combined simultaneously with drugs from four mechanistic classes in cell culture models of human leukemia and lymphoma. The impact of drug sequence and ratio on the interactions argues for incorporation of these parameters into the design of combination chemotherapy regimens
