Shifting Sociodemographic Characteristics of a Phase I Clinical Trial Population at an NCI-Designated Comprehensive Cancer Center in the Southeast.

Racial and ethnic minority populations are consistently under-represented in oncology clinical trials despite comprising a disproportionate share of a cancer burden. Phase I oncology clinical trials pose a unique challenge and opportunity for minority inclusion. Here we compared the sociodemographic characteristics of patients participating in phase 1 clinical trials a National Cancer Institute ( NCI)-designated comprehensive center to all patients at the center, patients with new cancer diagnosis in metropolitan Atlanta and patients with new cancer diagnoses in the state of Georgia. From 2015 to 2020, 2325 patients (43.4% female, 56.6% male) consented to participate in a phase I trial. Grouped self-reported race distribution was 70.3% White, 26.2% Black, and 3.5% other. Of new patient registrations at Winship Cancer Institute (N = 107 497) (50% F, 50% M), grouped race distribution was 63.3% White, 32.0% Black, and 4.7% other. Patients with new cancer diagnoses in metro Atlanta from 2015 to 2016 (N = 31101) were 58.4% White, 37.2% Black, and 4.3% other. Race and sex distribution of phase I patients was significantly different than Winship patients (P < .001). Over time, percent of White patients decreased in both phase I and Winship groups (P = .009 and P < .001, respectively); percentage of females did not change in either group (P = .54 phase I, P = .063 Winship). Although phase I patients were more likely to be White, male, and privately ensured than the Winship cohort, from 2015 to 2020 the percentage of White patients in phase I trials and among all new patients treated at Winship decreased. The intent of characterizing existing disparities is to improve the representation of patients from racial and ethnic minority backgrounds in phase I clinical trials.

Grafting Tomato to Manage Southern Blight, Prevent Yield Loss, and Increase Crop Value.

Southern blight, caused by the soilborne fungus Athelia rolfsii, has increased in frequency and severity in the southern United States since the use of methyl bromide fumigation ceased. The objective of this study was to evaluate three cultivars of sticky nightshade (Solanum sisymbriifolium), previously used as tomato rootstocks because of resistance to root-knot nematode, for resistance to southern blight. Field experiments in infested soil were done in Georgia in 2020 and 2021 and in South Carolina in 2021. Tomato cultivar Roadster was used as the scion. Control treatments included nongrafted 'Roadster' in all experiments and self-grafted 'Roadster' in Georgia. In all three experiments, all rootstocks significantly reduced incidence of southern blight and increased vigor ratings compared to control treatments (P ≤ 0.007). The rootstocks Maxifort, White Star, and SisSyn II, but not Diamond, significantly increased marketable weight (P ≤ 0.02) and crop value (P < 0.05) compared to control treatments. In South Carolina only, because of greater yields than in Georgia, net returns with Maxifort and White Star were significantly greater than net return with nongrafted 'Roadster' (P = 0.004). When the wholesale price for fresh market tomato is ≥$13/box, grafting may be an effective and economical management for southern blight.

Virtual Care and Urinary Tract Infection Management: Comparing Ancillary Service Orders and Patient Order Fulfillments Between Virtual and In-person Encounters During the COVID-19 Pandemic in the United States.

BACKGROUND: During the COVID-19 pandemic, more health care issues were being managed remotely. Urinary tract infections (UTIs) are being managed more often using telehealth although few reports compare the rate of UTI ancillary service orders placed and fulfilled during these visits. OBJECTIVES: We aimed to evaluate and compare the rate of ancillary service orders and order fulfillments in incident UTI diagnoses between virtual and in-person encounters. RESEARCH DESIGN: The retrospective cohort study involved 3 integrated health care systems: Kaiser Permanente (KP) Colorado, KP Georgia, and KP Mid-Atlantic States. SUBJECTS: We included incident UTI encounters from adult primary care data from January 2019 to June 2021. MEASURES: Data were categorized as: prepandemic (January 2019-March 2020), COVID-19 Era 1 (April 2020-June 2020), and COVID-19 Era 2 (July 2020-June 2021). UTI-specific ancillary services included medication, laboratory, and imaging. Orders and order fulfillments were dichotomized for analyses. Weighted percentages for orders and fulfillments were calculated using inverse probability treatment weighting from logistic regression and compared between virtual and in-person encounters using χ2 tests. RESULTS: We identified 123,907 incident encounters. Virtual encounters increased from 13.4% prepandemic to 39.1% in COVID-19 Era 2. Ancillary service orders from virtual encounters were not placed as often as in-person encounters. However, the weighted percentage for ancillary service order fulfillment across all services remained above 65.3% across sites and eras, with many fulfillment percentages above 90%. CONCLUSIONS: Our study reported a high rate of order fulfillment for both virtual and in-person encounters. Health care systems should encourage providers to place ancillary service orders for uncomplicated diagnoses, such as UTI, to provide enhanced access to patient-centered care.

Implicit Racial Bias, Health Care Provider Attitudes, and Perceptions of Health Care Quality Among African American College Students in Georgia, USA.

OBJECTIVE: Due to racism, over 20% of African Americans, including college students in Georgia, receive poor quality health care. Consequently, most students are reluctant to utilize health care services in the state. This study examined biased racial attitudes of health care providers in Georgia, and African American Georgia State University (GSU) School of Public Health (SPH) students' perceptions of the quality of health care they receive from providers, the effects of such care, and student recommendations for the way forward. DESIGN: A mixed-methods cross-sectional design was used to collect data from 63 students across six domains using Qualtrics. RESULTS: Provider brushes off patient concerns when providing medical care (29.9%), stereotyping (26.9%), and the lack of communication during medical care (25.4%) were the three main implicit racial attitudes identified by GSU SPH students. Owing to the poor quality of care they receive from their health care providers, some students (28.4%) are reluctant to utilize health care services, distrust doctors that are not from their race (34.3%), do not adhere to treatment (19.4%), and prefer to use home remedies (28.4%) when ill. Students recommended cultural competency training, holding health care providers accountable for their actions, and increasing African American health care providers in Georgia as ways to address health care provider attitudes and quality of care. CONCLUSION: Negative provider attitudes impact the health and health-seeking behavior of African American college students in Georgia. These attitudes must be eliminated so barriers to clinical participation are removed, and student health outcomes optimized.

Examining HIV Diagnosis and Linkage to PrEP Prescription Among Members at An Integrated Health System in the Southeast United States.

Pre-Exposure Prophylaxis (PrEP) is a priority method for preventing HIV infection. This study's aims were threefold: (1) identify characteristics of members of a large health maintenance organization, Kaiser Permanente Georgia (KPGA), associated with HIV infection, (2) identify which member characteristics associated with HIV were also associated with PrEP prescription, and (3) identify which HIV-associated characteristics were associated with under- or over-prescribing of PrEP. Analysis of variables from the electronic medical record revealed that age, race, gender, mental health diagnosis, STI diagnosis, and sexual orientation were independently associated with HIV diagnosis. The same characteristics were independently associated with PrEP prescription except for race. Persons identifying as Black or unknown race, women, and/or heterosexual; and who had an STI diagnosis and/or illicit drug use had lower odds of being prescribed PrEP than of having an HIV diagnosis. The implications of these findings for improving physician identification of candidates for PrEP prescription are discussed.

"I don't regret it at all. It's just I wish the process had a bit more humanity to it a bit more holistic": a qualitative, community-led medication abortion study with Black and Latinx Women in Georgia, USA.

Traditional family planning research has excluded Black and Latinx leaders, and little is known about medication abortion (MA) among racial/ethnic minorities, although it is an increasingly vital reproductive health service, particularly after the fall of Roe v. Wade. Reproductive justice (RJ) community-based organisation (CBO) SisterLove led a study on Black and Latinx women's MA perceptions and experiences in Georgia. From April 2019 to December 2020, we conducted key informant interviews with 20 abortion providers and CBO leaders and 32 in-depth interviews and 6 focus groups (n = 30) with Black and Latinx women. We analysed data thematically using a team-based, iterative approach of coding, memo-ing, and discussion. Participants described multilevel barriers to and strategies for MA access, wishing that "the process had a bit more humanity … [it] should be more holistic." Barriers included (1) sociocultural factors (intersectional oppression, intersectional stigma, and medical experimentation); (2) national and state policies; (3) clinic- and provider-related factors (lack of diverse clinic staff, long waiting times); and (4) individual-level factors (lack of knowledge and social support). Suggested solutions included (1) social media campaigns and story-sharing; (2) RJ-based policy advocacy; (3) diversifying clinic staff, offering flexible scheduling and fees, community integration of abortion, and RJ abortion funds; and (4) social support (including abortion doulas) and comprehensive sex education. Findings suggest that equitable MA access for Black and Latinx communities in the post-Roe era will require multi-level intervention, informed by community-led evidence production; holistic, de-medicalised, and human rights-based care models; and intersectional RJ policy advocacy.

Sex-Positivity, Medical Mistrust, and PrEP Conspiracy Beliefs Among HIV-Negative Cisgender Black Sexual Minority Men in Atlanta, Georgia.

Because the public health response to the disproportionate HIV burden faced by Black sexual minority men (BSMMM) has focused on sexual risk reduction and disease prevention, other vital components of sexual health (e.g., intimacy, pleasure, benefits of sex) have been often overlooked. Sex-positive describes a more open, holistic approach toward sex and sexuality that prioritizes these other components, though such an approach is rarely applied to BSMM's sexual health. For sex-positive BSMM, risk/preventive discourse may foster or exacerbate medical mistrust as a reaction to the dissonance between how these men view sexual health and how the medical establishment views it, which may discourage sexual healthcare-seeking. We assessed sex-positivity and its association with medical mistrust and PrEP conspiracy beliefs among 206 HIV-negative cisgender BSMM in Atlanta, Georgia. We performed exploratory factor analytic procedures on responses to a sex-positivity scale, followed by multivariable linear regressions to determine sex-positivity's associations with medical mistrust and PrEP conspiracy beliefs. We extracted two sex-positivity factors: sexual freedom (α = 0.90), reflecting openness toward casual sex and rejection of sexual mores, and essence of sex (α = 0.77), reflecting the intimate, relational, and pleasurable qualities of sex. Sexual freedom was independently associated with perceived provider deception (ß = 0.19, CI = 0.04, 0.34). Essence of sex was independently associated with PrEP conspiracy beliefs (ß = 0.16, CI = 0.02, 0.31) and marginally associated with perceived provider deception (ß = 0.14, CI = - 0.00, 0.29). Healthcare providers and public health practitioners may cultivate greater trust with BSMM by incorporating a sex-positive approach into patient/participant interactions, clinical decision-making, and interventions. Improving access to sexual pleasure acknowledges BSMM's right to optimal, holistic sexual health.

Pseudomonas alliivorans sp. nov., a plant-pathogenic bacterium isolated from onion foliage in Georgia, USA.

This study provides a taxonomic characterization of three bacterial strains isolated from onion seedlings in Georgia USA. Yellow-colored colonies were isolated, and a diffusible fluorescent pigment was visible under ultraviolet light on King's medium B. Preliminary analysis of the basic phenotype tests and 16S rRNA gene sequence analysis indicated the onion strains were closely related to Pseudomonas viridiflava with the highest similarity to P. viridiflava DSM 6694T (99.6%). The phylogenomic analyses based on whole genome sequences showed that the onion strains formed a separate monophyletic clade from other species with P. viridiflava as the closest neighbor. When the onion strains and the P. viridiflava type strain were compared, the average nucleotide identity values was 91.6%. Additionally, the digital DNA-DNA hybridization values of the onion strains were 45.8% or less when compared to the type strains of their close relatives, including P. viridiflava. In addition, biochemical, physiological features, and cellular fatty acid compositions were determined for a polyphasic taxonomic analysis. The results supported that the three onion strains represented a novel Pseudomonas species. We propose a new species as Pseudomonas alliivorans sp. nov., with 20GA0068T (=LMG 32210T = CFBP 8885T) as the type strain. The DNA G + C content of the strain 20GA0068T is 59.1 mol%.

Multistakeholder perspectives on the strengthening and embedding of mandatory continuing medical education in Georgia: a qualitative study.

OBJECTIVE: Continuing medical education (CME) is a vital component of health systems. Setting up a CME system is a complex task, requiring involvement of stakeholders including educators, learners, institutions and policy makers. The aim of the study was to conduct qualitative research involving multiple stakeholders to explore the perceived effectiveness and shortcomings of the CME system in Georgia, its place in the health system and potential means of improving it. DESIGN: This is a qualitative study. All data were collected using semistructured individual interviews. The questions were derived from the relevant literature. Data analysis was conducted using comparative strategy. PARTICIPANTS: We interviewed individuals from CME providers, medical establishments, the professional development board (PDB), and the Regulatory Agency for Medical and Pharmaceutical Activities. We thus interviewed 23 people (11 people from CME providers, 8 people from medical establishments, 3 PDB members and 1 person from Legal Entity under Public Law Regulatory Agency for Medical and Pharmaceutical Activities). RESULTS: Georgia has had experience of mandatory CME in the past, which had been criticised for its poor quality and bureaucratic processes. CME is viewed as an essential developmental process for medical professionals, the outcome of which is to deliver high-quality medical care. Our interviewees identified a clear need for high-quality CME courses. However, significant challenges that need to be overcome include financial barriers, doctors' attitudes to CME, a lack of CME courses in all medical specialties and relatively weak professional associations. CONCLUSION: CME is widely recognised as an essential pillar in providing quality medical care. Establishing high-quality CME requires a strategic and holistic approach. In order to ensure the sustainable and effective implementation of the CME process, we need to take into account stakeholders' interests and expectations, the socioeconomic status and development of the country, and past experiences of all relevant individuals and organisations.

Long-term pollen trends and associations between pollen phenology and seasonal climate in Atlanta, Georgia (1992-2018).

BACKGROUND: Previous research has revealed that airborne pollen concentrations and phenology in allergenic plants are changing. In addition, variations in seasonal climate are known to affect pollen phenology in trees, weeds, and grasses. OBJECTIVE: To investigate localized trends in pollen concentrations and pollen phenology over time and the effect of seasonal climate variations. METHODS: We used daily pollen count concentrations from a National Allergy Bureau pollen counting station located in metropolitan Atlanta, Georgia, for 13 allergenic taxa. To evaluate long-term trends over time, we developed linear regression models for 6 pollen measures. To evaluate the effect of seasonal climate on phenology, we developed regression models using seasonal climate measures as independent variables and pollen measures as dependent variables. RESULTS: For several tree pollen taxa, pollen concentrations increased over time, including oak and juniper pollen. In multiple species, pollen seasons trended toward an earlier release throughout the 27-year period. Variations in seasonal climate did have an effect on pollen counts and the timing of pollen release but varied by taxa. Generally, warmer spring temperatures were associated with an earlier pollen release. In addition, increased precipitation from the preceding fall was associated with increased pollen concentration in the spring months. CONCLUSION: Allergenic pollen concentrations for several types of pollen are increasing and trending toward an earlier pollen release in Atlanta, Georgia. Warmer temperatures preceding the pollen season were associated with the earlier pollen release.

Clinical, behavioural and social factors associated with racial disparities in COVID-19 patients from an integrated healthcare system in Georgia: a retrospective cohort study.

OBJECTIVES: To identify sociodemographic, clinical and behavioural drivers of racial disparities and their association with clinical outcomes among Kaiser Permanente Georgia (KPGA) members with COVID-19. DESIGN: Retrospective cohort of patients with COVID-19 seen from 3 March to 29 October 2020. We described the distribution of underlying comorbidities, quality of care metrics, demographic and social determinants of health (SDOH) indicators across race groups. We also described clinical outcomes in hospitalised patients including length of stay, intensive care unit (ICU) admission, readmission and mortality. We performed multivariable analyses for hospitalisation risk among all patients with COVID-19 and stratifyied by race and sex. SETTING: KPGA, an integrated healthcare system. PARTICIPANTS: 5712 patients who all had laboratory-confirmed COVID-19. Of them, 57.8% were female, 58.4% black, 29.5% white, 8.5% Hispanic and 3.6% Asian. RESULTS: Black patients had the highest proportions of living in neighborhoods under the federal poverty line (12.4%) and in more deprived locations (neighbourhood deprivation index=0.4). Overall, 14.4% (n=827) of this cohort was hospitalised. Asian patients had the highest rates of ICU admission (53.1%) and mechanical ventilation (21.9%). Among all patients, Hispanics (adjusted 1.60, 95% CI (1.08, 2.37)), blacks (1.43 (1.13, 1.83)), age in years (1.03 (1.02, 1.04)) and living in a zip code with high unemployment (1.08 (1.03, 1.13)) were associated with higher odds of hospitalisation. COVID-19 patients with chronic obstructive pulmonary disease (2.59 (1.67, 4.02)), chronic heart failure (1.79 (1.31, 2.45)), immunocompromised (1.77 (1.16, 2.70)), with glycated haemoglobin >8% (1.68 (1.19, 2.38)), depression (1.60 (1.24, 2.06)), hypertension (1.5 (1.21, 1.87)) and physical inactivity (1.25 (1.03, 1.51)) had higher odds of hospitalisation. CONCLUSIONS: Black and Hispanic KPGA patients were at higher odds of hospitalisation, but not mortality, compared with other race groups. Beyond previously reported sociodemographics and comorbidities, factors such as quality of care, lifestyle behaviours and SDOH indicators should be considered when designing and implementing interventions to reduce COVID-19 racial disparities.

Health Care Utilization and Clinical Characteristics of Nonhospitalized Adults in an Integrated Health Care System 28-180 Days After COVID-19 Diagnosis - Georgia, May 2020-March 2021.

As of April 19, 2021, 21.6 million COVID-19 cases had been reported among U.S. adults, most of whom had mild or moderate disease that did not require hospitalization (1). Health care needs in the months after COVID-19 diagnosis among nonhospitalized adults have not been well studied. To better understand longer-term health care utilization and clinical characteristics of nonhospitalized adults after COVID-19 diagnosis, CDC and Kaiser Permanente Georgia (KPGA) analyzed electronic health record (EHR) data from health care visits in the 28-180 days after a diagnosis of COVID-19 at an integrated health care system. Among 3,171 nonhospitalized adults who had COVID-19, 69% had one or more outpatient visits during the follow-up period of 28-180-days. Compared with patients without an outpatient visit, a higher percentage of those who did have an outpatient visit were aged ≥50 years, were women, were non-Hispanic Black, and had underlying health conditions. Among adults with outpatient visits, 68% had a visit for a new primary diagnosis, and 38% had a new specialist visit. Active COVID-19 diagnoses* (10%) and symptoms potentially related to COVID-19 (3%-7%) were among the top 20 new visit diagnoses; rates of visits for these diagnoses declined from 2-24 visits per 10,000 person-days 28-59 days after COVID-19 diagnosis to 1-4 visits per 10,000 person-days 120-180 days after diagnosis. The presence of diagnoses of COVID-19 and related symptoms in the 28-180 days following acute illness suggests that some nonhospitalized adults, including those with asymptomatic or mild acute illness, likely have continued health care needs months after diagnosis. Clinicians and health systems should be aware of post-COVID conditions among patients who are not initially hospitalized for acute COVID-19 disease.

Regulatory environment for complementary and alternative medicine in Georgia-a health policy analysis.

International bodies such as the WHO call on member states to regulate and, where possible, integrate Complementary and Alternative Medicine (CAM) into health systems, to the benefit and safety of patients. Research on CAM regulations in the Republic of Georgia has been limited. The aim of this study was to identify key actors and analyse the regulatory environment for CAM in Georgia in its local and international contexts. We conducted a health policy analysis using a triangle framework of content, context and processes. We used data from national government, professional associations and academia; and drew from primary qualitative data of stakeholders' perspectives and needs regarding CAM in Georgia. The several CAM associations we identified have limited capacities for self-regulation. CAM practices are currently not effectively regulated in Georgia, while the government has no expressed intention to develop regulatory frameworks. Georgia's CAM health policy is currently not compliant with WHO and European directives and recommendations. Government, lawmakers, public administration, academia, physicians, non-physician CAM practitioners and other actors should constitute a national working group dedicated to CAM regulations in Georgia to identify, classify CAM practices; and develop core principles for policy making for safe and effective CAM practiced in Georgia's health system.

Factors Contributing to Vitamin D Status at Hospital Admission for Pulmonary Exacerbation in Adults With Cystic Fibrosis.

BACKGROUND: Individuals with cystic fibrosis (CF) have difficulty maintaining optimal vitamin D status due to pancreatic insufficiency-induced malabsorption, inadequate sunlight exposure, and poor intake of vitamin D containing foods. Vitamin D deficiency may increase the risk of pulmonary exacerbations of CF. The objective of this study was to assess factors impacting vitamin D status in patients with CF recently hospitalized for a pulmonary exacerbation of CF. METHODS: This was a pre-planned analysis of vitamin D intake in patients enrolled in a multi-center, double-blind, randomized controlled study examining vitamin D therapy for pulmonary exacerbation of CF. Demographic information, responses from a habitual sun exposure questionnaire and food frequency questionnaire, and vitamin D supplement usage were queried and compared to serum 25-hydroxyvitamin D (25(OH)D) concentrations. RESULTS: A total of 48 subjects were included in this analysis. Subjects were taking approximately 1,200 IU of vitamin D daily. Reported vitamin D intake, age, race, employment, and education were not significantly associated with vitamin D status in this population. However, smoking status, sunlight exposure in the last 3 years, and skin type (in the bivariate model) were all significantly associated with vitamin D status (all p<0.05). CONCLUSIONS: Sunlight exposure was the most predictive determinant of vitamin D status in patients with CF prior to pulmonary exacerbation. Subjects reported vitamin D intake below the recommended amounts. The role and mode of optimizing vitamin D status prior to a pulmonary exacerbation needs further investigation.

Intravesical bacteriophages for treating urinary tract infections in patients undergoing transurethral resection of the prostate: a randomised, placebo-controlled, double-blind clinical trial.

BACKGROUND: Urinary tract infections (UTIs) are among the most prevalent microbial diseases and their financial burden on society is substantial. In the context of increasing antibiotic resistance, finding alternative treatments for UTIs is a top priority. We aimed to determine whether intravesical bacteriophage therapy with a commercial bacteriophage cocktail is effective in treating UTI. METHODS: We did a randomised, placebo-controlled, clinical trial, at the Alexander Tsulukidze National Centre of Urology, Tbilisi, Georgia. Men older than 18 years of age, who were scheduled for transurethral resection of the prostate (TURP), with complicated UTI or recurrent uncomplicated UTI but no signs of systemic infection, were allocated by block randomisation in a 1:1:1 ratio to receive intravesical Pyo bacteriophage (Pyophage; 20 mL) or intravesical placebo solution (20 mL) in a double-blind manner twice daily for 7 days, or systemically applied antibiotics (according to sensitivities) as an open-label standard-of-care comparator. Urine culture was taken via urinary catheter at the end of treatment (ie, day 7) or at withdrawal from the trial. The primary outcome was microbiological treatment response after 7 days of treatment, measured by urine culture; secondary outcomes included clinical and safety parameters during the treatment period. Analyses were done in a modified intention-to-treat population of patients having received at least one dose of the allocated treatment regimen. This trial is registered with ClinicalTrials.gov, NCT03140085. FINDINGS: Between June 2, 2017, and Dec 14, 2018, 474 patients were screened for eligibility and 113 (24%) patients were randomly assigned to treatment (37 to Pyophage, 38 to placebo, and 38 to antibiotic treatment). 97 patients (28 Pyophage, 32 placebo, 37 antibiotics) received at least one dose of their allocated treatment and were included in the primary analysis. Treatment success rates did not differ between groups. Normalisation of urine culture was achieved in five (18%) of 28 patients in the Pyophage group compared with nine (28%) of 32 patients in the placebo group (odds ratio [OR] 1·60 [95% CI 0·45-5·71]; p=0·47) and 13 (35%) of 37 patients in the antibiotic group (2·66 [0·79-8·82]; p=0·11). Adverse events occurred in six (21%) of 28 patients in the Pyophage group compared with 13 (41%) of 32 patients in the placebo group (OR 0·36 [95% CI 0·11-1·17]; p=0·089) and 11 (30%) of 37 patients in the antibiotic group (0·66 [0·21-2·07]; p=0·47). INTERPRETATION: Intravesical bacteriophage therapy was non-inferior to standard-of-care antibiotic treatment, but was not superior to placebo bladder irrigation, in terms of efficacy or safety in treating UTIs in patients undergoing TURP. Moreover, the bacteriophage safety profile seems to be favourable. Although bacteriophages are not yet a recognised or approved treatment option for UTIs, this trial provides new insight to optimise the design of further large-scale clinical studies to define the role of bacteriophages in UTI treatment.

Characterization of Trace Elements in Atmospheric Deposition Studied by Moss Biomonitoring in Georgia.

The present work was conducted to obtain and highlight the first comprehensive baseline data on atmospheric deposition of trace elements and to evaluate the air quality in Georgia. A total of 120 moss samples were collected over accessible territories in Georgia in the period from 2014 to 2017. Hylocomium splendens (Hedw.) Schimp., Hypnum cupressiforme (Hedw.), and Pleurozium schreberi (Brid.) Mitt. moss species were analyzed by two complementary analytical techniques: instrumental neutron activation analysis and atomic absorption spectrometry. Concentrations of 41 elements in mg/kg were determined. The concentrations were compared with the corresponding values in the literature and are in a good agreement, except for the concentration of Mg, Al, K, Ca, Ti, and Fe, which were higher than those reported for other countries. The principal component and discriminant analyses were implemented to extract information about the similar geochemical features and to decipher the provenance of the studied elements. The analysis showed that a considerable association of crustal elements and the provenance of elements can be considered as a mixture of geogenic and anthropogenic sources. In addition, the influence of different latitudinal climate zones on the distribution of elements in the atmospheric deposition was observed. The enrichment factor shows considerable values for Th and Zr. The spatial distribution of the pollution load index identifies four zones (#12, 38, 53, and 64). The potential ecological risk index and the risk index were calculated and it does not pose significant risk except As and Cd. The data obtained can be used as the first dataset of metal characterization of air pollution in Georgia.

Geriatric Elements and Oral Anticoagulant Prescribing in Older Atrial Fibrillation Patients: SAGE-AF.

OBJECTIVES: Oral anticoagulants are the cornerstone of stroke prevention in high-risk patients with atrial fibrillation (AF). Geriatric elements, such as cognitive impairment and frailty, commonly occur in these patients and are often cited as reasons for not prescribing oral anticoagulants. We sought to systematically assess geriatric impairments in patients with AF and determine whether they were associated with oral anticoagulant prescribing. DESIGN: Cross-sectional analysis of baseline data from the ongoing Systematic Assessment of Geriatric Elements in Atrial Fibrillation (SAGE-AF) prospective cohort study. SETTING: Multicenter study with site locations in Massachusetts and Georgia that recruited participants from cardiology, electrophysiology, and primary care clinics from 2016 to 2018. PARTICIPANTS: Participants with AF age 65 years or older, CHA2 DS2 -VASc (congestive heart failure; hypertension; aged ≥75 y [doubled]; diabetes mellitus; prior stroke, transient ischemic attack, or thromboembolism [doubled]; vascular disease; age 65-74; female sex) score of 2 or higher, and no oral anticoagulant contraindications (n = 1244). MEASUREMENTS: A six-component geriatric assessment included validated measures of frailty, cognitive function, social support, depressive symptoms, vision, and hearing. Oral anticoagulant use was abstracted from the medical record. RESULTS: A total of 1244 participants (mean age = 76 y; 49% female; 85% white) were enrolled; 42% were cognitively impaired, 14% frail, 53% pre-frail, 12% socially isolated, and 29% had depressive symptoms. Oral anticoagulants were prescribed to 86% of the cohort. Oral anticoagulant prescribing did not vary according to any of the geriatric elements (adjusted odds ratios [ORs] for oral anticoagulant prescribing and cognitive impairment: OR = .75; 95% confidence interval [CI] = .51-1.09; frail OR = .69; 95% CI = .35-1.36; social isolation OR = .90; 95% CI = .52-1.54; depression OR = .79; 95% CI = .49-1.27; visual impairment OR = .98; 95% CI = .65-1.48; and hearing impairment OR = 1.05; 95% CI = .71-1.54). CONCLUSION: Geriatric impairments, particularly cognitive impairment and frailty, were common in our cohort, but treatment with oral anticoagulants did not differ by impairment status. These geriatric impairments are commonly cited as reasons for not prescribing oral anticoagulants, suggesting that prescribers may either be unaware or deliberately ignoring the presence of these factors in clinical settings.

Religiosity and Patient Activation Among Hospital Survivors of an Acute Coronary Syndrome.

BACKGROUND: Optimum management after an acute coronary syndrome (ACS) requires considerable patient engagement/activation. Religious practices permeate people's lives and may influence engagement in their healthcare. Little is known about the relationship between religiosity and patient activation. OBJECTIVE: To examine the association between religiosity and patient activation in hospital survivors of an ACS. DESIGN: Secondary analysis using baseline data from Transitions, Risks, and Actions in Coronary Events: Center for Outcomes Research and Education (TRACE-CORE) Study. PARTICIPANTS: A total of 2067 patients hospitalized for an ACS at six medical centers in Central Massachusetts and Georgia (2011-2013). MAIN MEASURES: Study participants self-reported three items assessing religiosity-strength and comfort from religion, making petition prayers, and awareness of intercessory prayers for health. Patient activation was assessed using the 6-item Patient Activation Measure (PAM-6). Participants were categorized as either having low (levels 1 and 2) or high (levels 3 and 4) activation. RESULTS: The mean age of study participants was 61 years, 33% were women, and 81% were non-Hispanic White. Approximately 85% derived strength and comfort from religion, 61% prayed for their health, and 89% received intercessory prayers for their health. Overall, 58% had low activation. Reports of a great deal (aOR, 2.02; 95% CI, 1.44-2.84), and little/some (aOR, 1.45; 95% CI, 1.07-1.98) strength and comfort from religion were associated with high activation, as were receipt of intercessions (aOR, 1.48; 95% CI, 1.07-2.05). Praying for one's health was associated with low activation (aOR, 0.78; 95% CI, 0.61-0.99). CONCLUSIONS: Most ACS survivors acknowledge religious practices toward their recovery. Strength and comfort from religion and intercessory prayers for health were associated with high patient activation. Petition prayers for health were associated with low activation. Healthcare providers should use knowledge about patient's religiosity to enhance patient engagement in their care.

The Association Between Stroke Mortality and Time of Admission and Participation in a Telestroke Network.

OBJECTIVES: Acute ischemic stroke is one of the leading causes of death. Patient outcomes, such as in-patient mortality, may be impacted by the time of arrival to the hospital. Telestroke networks have been found to be effective and safe at treating acute ischemic strokes. This paper investigated the association between mortality and time of arrival and hospital's participation in a telestroke network. METHODS: Data were collected on ischemic stroke patients who arrived at 15 nonteaching hospitals in Georgia's Paul Coverdell Acute stroke registry from 2009 to 2016. After controlling for patient and hospital characteristics, multivariate logistic regression was conducted to assess whether time of arrival and telestroke participation was associated with in-hospital mortality. Subgroup analysis was conducted based on hospital bed size. RESULTS: Overall, a total of 19,759 admissions for acute ischemic stroke were included in this analysis. The odds of dying in the hospital when arriving during the nighttime are 1.22 times the odds of dying when arriving during the day (95% CI: 1.04-1.45) and the odds of dying at a telestroke hospital are 53% lower than at a nontelestroke hospital (OR .47, 95% CI .31-.71). The associations were more prominent in large hospitals. CONCLUSIONS: Our study found that the hour of arrival for acute ischemic stroke is linked with in-hospital mortality in large hospitals, with patients more likely to die if they arrive during the nighttime hours as compared to the daytime hours. Telestroke participation is linked with lower odds of hospital mortality in all hospitals.

New and Worsening Long-term Immune-Related Adverse Events with PD-1/PD-L1 Pathway Agents in Patients with Cancer.

STUDY OBJECTIVES: Immune checkpoint inhibitors have produced durable responses across a variety of cancers. Although programmed cell death protein 1 (PD-1) and its ligand (PD-L1) inhibitors activate T cells against tumor cells, they may also cause autoimmune-like toxicities termed immune-related adverse events (irAEs). Although much is known regarding irAEs that occur early during treatment, data on the long-term toxicity profile of these agents are more limited. Our primary objective was to evaluate the frequency of patients receiving anti-PD-1/PD-L1 therapy for at least 6 continuous months who experienced new or worsening irAEs requiring clinical interventions. Secondary objectives included assessment of other factors associated with clinically significant irAEs after at least 6 months of therapy. DESIGN: Retrospective chart review. SETTING: Large university-affiliated National Cancer Institute-designated comprehensive cancer center. PATIENTS: A total of 159 adults diagnosed with any malignancy who received a PD-1/PD-L1 inhibitor-nivolumab, pembrolizumab, or atezolizumab-as monotherapy or with concurrent cytotoxic agents, for at least 6 months, between January 1, 2014, and September 1, 2017. MEASUREMENTS AND MAIN RESULTS: We collected information on the incidence and timing of irAEs, along with patient demographics and other treatment outcomes. Thirty-eight patients (24%) experienced clinically significant, new, or worsening irAEs after 6 months of treatment with anti-PD-1/PD-L1 therapy. Hypothyroidism was the most common irAE experienced (20 patients [12.6%]), followed by pneumonitis (5 patients [3%]); 2 patients died due to pneumonitis. Four patients (2.5%) had a deepened disease response beyond 6 months of treatment. CONCLUSION: Our results revealed that a significant proportion of patients continue to experience irAEs with long-term use of PD-1/PD-L1 inhibitors. These results further contribute to the risk-benefit understanding of chronic PD-1/PD-L1 antagonism and support discontinuation of these agents following deepest response.
