Background: Kidney disease is a leading cause of death in the United States and the world. Proteinuria signifies kidney damage and can exacerbate kidney disease. It has become an important indicator of kidney disease; reducing proteinuria results in renoprotective effects and slows renal disease. Existing treatments do not work for every patient. Aim of Study: Amaranth is a tropical plant that was regularly consumed in the ancient Central American diet. It has a plethora of health effects and is a strong functional food candidate. This study examines whether a regular oral dose of amaranth oil decreased proteinuria concentration in murine subjects.  Methods: Mice in the experimental group (n = 3) were given 4μl of amaranth oil per gram of mouse weight for 5 days a week over 84 days. Control mice (n = 2) were sham treated on the same schedule with no oil. Urine protein concentration was determined by Bradford assay, measuring absorbance at 595nm, then comparing with a BSA standard curve.  Results: The experimental group showed decreased proteinuria levels throughout the entire 84 days of study.Conclusion: Results show amaranth oil may help decrease proteinuria levels in lupus prone murine subjects. Given the small sample size, the data are preliminary. More research is needed to validate the results, and determine the optimal dose and treatment schedule. Key words: proteinuria, amaranth oil, renoprotective, kidney disease, renal disease, lupus, functional food

e17502 Background: Glassy cell carcinoma of cervix (GCCC) is a rare histological subtype of cervical cancer which has historically been associated with rapidly progressive disease, early development of metastases and overall poor prognosis. We attempt to define real-world trends in GCCC in the United States based on data from SEER (Surveillance, Epidemiology and End Results) database. Methods: We extracted data from the US National Cancer Institute's SEER 2018 dataset using ICD-O code for ‘Cervix Uteri Glassy Cell Carcinoma’. All patients who were diagnosed between 1973-2015 were included. Statistical analysis was done using SPSS 26. Kaplan Meier curve was used for survival analysis. Results: Data for a total of 57 patients with GCCC was available from 1975 to 2017. Median age at diagnosis was 38 years (range 30.5-44.5). Increased frequency of cases was noted in white females (77.2%) as compared to black population (22.2%). Most cases initially presented with localized or regional spread (47.4% and 40.4% respectively) with distant metastasis seen in only 10.5% patients. Data analysis revealed that 63.2% patients had Grade III poorly differentiated carcinoma, 66.7% received radiation therapy, 57.9% underwent chemotherapy and 59.6% had cancer direceted surgery performed. Calculated mean overall survival was 121.9 months. We were unable to calculate 5 year and 10 year median overall survival due to small sample size and censored data. Conclusions: GCCC is a rare histologic type of cervical cancer that presents at a younger age, is more frequently seen in white females and is commonly associated with localized or regional spread at time of initial presentation.[Table: see text]

Educational leaders throughout the United States have repeatedly emphasized the importance of increasing the number of Black and Latinx teachers in American schools. Prior qualitative work suggests that Black and Latinx teachers who are demographically isolated in their schools often report negative experiences. Drawing on theories of proportional representation in organizations, we use Tennessee statewide survey and administrative data to examine whether self-reported professional experiences of Black and Latinx teachers are different when they are demographically isolated. We estimate models using two measures of demographic isolation: a continuous measure and a theoretically generated ordinal measure. We find that, for Black teachers, the percentage of Black teachers in the school is positively associated with teachers’ perceived satisfaction and support and with the frequency of collaboration. There is also some evidence of threshold effects of demographic isolation for Black teachers, as Black teachers in schools in which at least 60% of fellow teachers are Black report significantly higher satisfaction and support than other Black teachers. Our models do not find any associations between isolation and professional experience for Latinx teachers, but a small sample size and lack of variation in demographic isolation among Latinx teachers makes it difficult to estimate these associations. Our findings suggest that both ordinal and continuous measures of demographic isolation may be useful when examining relationships between demographic isolation and workplace experiences. Because we study factors linked to turnover in prior research, these analyses can contribute to the broader discussion about the retention of Black and Latinx teachers.

10598 Background: African Americans (AA) have the highest breast cancer (BC) mortality rate. Access to treatment is a known contributing factor. In the past 4 years, several targeted therapies for HER2- BC have become available which require testing for specific biomarkers. This study assessed the impact of race on biomarker testing rates in HER2- ABC pts receiving treatment in the US. Methods: Oncologists were recruited to abstract data from medical charts for the next 8-10 pts receiving treatment with HER2- ABC during Sept 2019-Apr 2020. Pts records were stratified by race and categorized into 3 mutually exclusive cohorts [White/Caucasian (White), AA, Other]. The other race cohort was excluded from this analysis due to small sample size. Differences in pt demographics/clinical characteristics were analyzed via Fisher’s exact tests. Testing rates for actionable biomarkers (i.e. BRCA1/2, PIK3CA, PD-L1) were compared between White and AA pts utilizing logistic regressions controlling for age, known family history of a BRCA-related cancer, hormone receptor (HR) status and practice setting (academic vs. community). Further analyses by age will be presented. Results: This analysis included 378 pts records, provided by 40 oncologists. Mean age was 64 years; 77% had HR+/HER2- ABC; 20% had advanced triple negative breast cancer (TNBC), 3% had ABC with an unknown HR status. Compared to White pts, AA pts were significantly more likely to have advanced TNBC (27% vs. 18%, p<0.05). Compared to White pts, AA pts had significantly lower BRCA1/2 mutation (mut) testing rates (Table). Numerically lower rates of PIK3CAmut and PD-L1 testing were observed among AA pts (Table). BRCA1/2mut positivity rate (germline [g] and/or somatic [s]) was higher among AA vs. White pts (30% vs. 22%). Positivity rate for PIK3CAmut was lower for AA vs. White pts (8% vs. 11%). Conclusions: A higher than expected BRCA1/2mut positivity rate was observed than previously reported in the literature. This is likely because this analysis included s BRCA1/2mut and represented a high risk pt population. Across all biomarkers assessed, AA pts had lower testing rates than White pts. This suggests racial disparities in testing rates of actionable biomarkers. Consistent with guidelines, and with the increased availability of targeted therapies, focused efforts should be developed to increase biomarker testing in AA pts.

Introduction: Since the CREDENCE trial results, the American Diabetes Association (ADA) recommends SGLT-2 inhibitors as first line therapy for patients with stage III Chronic Kidney Disease (CKD) or proteinuric CKD, regardless of baseline A1C. We project the number of US individuals with diabetes and renal disease that meets inclusion into the CREDENCE trial and that are recommended for SGLT-2 inhibitors based on the guidelines. Methods: Our initial cohort consisted of 48,710 individuals from the 2007-2016 National Health and Nutrition Examination Survey with survey weights designed to estimate the US population. CREDENCE eligible patients were patients with diabetes who had an eGFR of 30-90 and urine albumin-to-creatinine ratio (UACR) of >300 mg/g. Guideline eligible patients were stage III CKD individuals and those with a UACR > 30 mg/g. Results: In the US population, 21,411,059 (+/-708,233) individuals are >=18 years and have diabetes. Of these individuals, 578,514 (+/-72,385) are CREDENCE eligible. Based on the ADA recommendations, 7,504,508 (+/- 342,139) adults with CKD and diabetes are recommended for an SGLT-2 inhibitor, representing 35.0% of individuals with diabetes. The mean age of guideline eligible individuals is 64.4 years, with 3,886,904 males (51.8%) and 3,617,604 females (48.2%). Conclusions: In the United States, a large number of individuals--approximately 35% of adults with diabetes--have renal disease characteristics that give them a first-line indication for SGLT-2 inhibitor initiation.

Chronic kidney disease (CKD) is a clinical syndrome arising from progressive kidney injury, formerly known as chronic renal failure, chronic renal disease, and chronic renal insufficiency. It is classified into five stages based primarily on glomerular filtration rate (GFR). This article discusses the epidemiology of CKD and end-stage renal disease (ESRD), as well as etiology and genetics, pathophysiology, and pathogenesis. The section on diagnosis looks at clinical manifestations and physical findings, laboratory (and other) tests, imaging studies, and biopsy. A short section on differential diagnosis is followed by a discussion of treatment, including hemodialysis and peritoneal dialysis. Long-term complications of patients on dialysis include cardiovascular disease, renal osteodystrophy, dialysis-related amyloidosis, and acquired cystic disease (renal cell carcinoma). The final section addresses prognosis and socioeconomic burden. Figures include the classification system for CKD, prevalence of CKD in the United States, rising prevalence, risk of, and leading causes of ESRD in the United States, plus the changing prevalence of ESRD over time, clinical manifestations of uremia, and an overview of hemodialysis circuit. Tables look at the burden of CKD relative to other chronic disorders, the specific hereditary causes of kidney disease, and situations when serum creatinine does not accurately predict GFR. Other tables list equations for estimating GFR, the causes of CKD without shrunken kidneys, and clinical features distinguishing chronic kidney disease from acute kidney injury. ESRD and indications for initiation of dialysis are presented, as well as typical composition of dialysate and reasons for failure of peritoneal dialysis. This chapter contains 71 references.

BackgroundEchocardiography has been a popular modality used to aid in the diagnosis of infective endocarditis (IE) with the modified Dukes' criteria. We evaluated the necessity between the uses of either a transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE) in patients with a body mass index (BMI) greater than or equal to 25 kg/m2 and less than 25.MethodsA single-centered, retrospective study of 198 patients between the years of 2005 and 2012 diagnosed with IE based on modified Dukes' criteria. Patients were required to be above the age of 18, undergone an echocardiogram study and had blood cultures to be included in the study.This study was conducted at a major hospital in one of the most diverse communities in the United States, providing a cultural and epidemiologically significant advantage. An approved chart analysis using QuadraMed Computerized Patient Record (QCPR) was retrospectively accessed with data-input and calculations formulated in computerized software.ResultsAmong 198 patients, two echocardiographic groups were evaluated as 158 patients obtained a TTE, 143 obtained a TEE, and 103 overlapped with TEE and TTE. 167 patients were included in the study as 109 (65%) were discovered to have native valve vegetations on TEE and 58 (35%) with TTE. TTE findings were compared to TEE results for true negative and positives to isolate valvular vegetations Overall sensitivity of TTE was calculated to be 67% with a specificity of 93%. Patients were further divided into two groups with the first group having a BMI less than or equal to 25 kg/m2 and the subsequent group with a BMI<25. Patients with a BMI less than or equal to 25 that underwent a TTE study had a sensitivity and specificity of 54% and 92, respectively. On the contrary, patients with a BMI<25 had a TTE sensitivity and specificity of 78% and 95, respectively. Furthermore, we obtained the sensitivities of specific valves diseased from vegetations, visualized by TTE (figure 1). Lastly, we were able to demonstrate a correlation between the different modalities of echocardiography used to the specific organism identified on blood cultures (figure 2).ConclusionCalculating a BMI in patients with suspicion for IE may provide benefit in reducing further diagnostic imaging. Our study demonstrated that patients having a BMI <25 kg/m2 with a negative TTE should refrain from further diagnostic studies with TEE, given the findings of increased sensitivities (figure 3). Patients with a BMI less than or equal to 25 may proceed directly to a TEE, possibly avoiding an additional study with a TTE given the low sensitivities identified in this population. Clinicians should be aware that this study has several limitations, one of which a small sample size that may be increased with a multi-centered study. Further investigations with a larger population may improve and possibly provide similar findings, reinforcing the study.

767 Background: The CORRECT trial (NCT01103323) showed that REG improves overall survival (OS) vs placebo (PBO) in patients with mCRC who failed approved therapies (OS HR 0.77; 1-sided p=0.0052; Grothey 2013). A total of 760 patients were randomized to REG (n=505) or PBO (n=255) in more than 100 centers across North America, Europe, Asia, and Australia. We conducted a post-hoc exploratory subgroup analysis of the 83 (11%) patients from 18 US centers. Methods: Eligible patients had an ECOG PS ≤1 and had received approved therapies, including a fluoropyrimidine, oxaliplatin, irinotecan, and bevacizumab, and if KRAS wild-type cetuximab and/or panitumumab. Data from the overall cohort, including US patients, are provided for perspective. Descriptive statistics are shown. Results: Of the 83 US patients, 36 (43%) were randomized to PBO and 47 (57%) to REG. Baseline characteristics of the US group were consistent with the overall cohort: median age in the US was 58 yr (range, 34 – 85) vs 61 (22 – 85) overall, 49% of US patients were ECOG PS1 (vs 46%), and 46% received ≤ 3 treatments for mCRC (vs 52%). KRAS status mutant/wild-type was 57%/34% in the US vs 57%/39% overall. All patients in the trial had prior bevacizumab and 57% of US patients also had prior cetuximab and/or panitumumab (vs 51% overall). However, higher proportion of patients in the US were Black (11% vs 2%), KRAS status unknown (10% vs 4%), and had colon as the primary disease site (82% vs 65%). Mean percentages of planned REG dose were similar (76% US vs 79% overall) and mean REG treatment duration was 3.1 mos in US vs 2.8 mos overall. Rates of dose modifications REG/PBO were 87%/47% in the US vs 76%/38% overall and grade ≥3 adverse events REG/PBO were 74%/64% vs 78%/49%, respectively. Based on 44 total death events, the HR for OS in the US subgroup was 0.46 (95%CI 0.25 – 0.84) favoring REG; median OS was 4.7 mos for PBO, but could not be estimated for REG due to censored data. However, this analysis was based on a relatively small sample size and event count. Conclusions: Patients treated in the CORRECT study in the US appear similar to the overall cohort and results are generally consistent with the overall findings of the trial. Clinical trial information: NCT01103323.

<p>This study focused on a lately constructed survey instrument that was intended to test the family perspective on a home visiting program and school. The four areas investigated were parent-teacher communications, student-teacher interactions, the parent’s perception of the school and the parents’ understanding of the home visiting program. The participants were selected from parents/guardians of 7th, 8th, 9th and 10th grade students at a Charter school in a southwestern major city in Texas, the United States of America. Twenty-two questions were asked to evaluate parent’s viewpoint with the four designated areas of interaction and communication of among school-parent-teacher. The findings showed that 73.5% of the students’ families living were in low income. The outcomes for reliability were promising (a = .909). Yet, the factor analysis outcomes of a rotated four-factor solution were insufficient to assess validity. This might be related to a small sample size (n = 45).</p>

Astronauts who undergo prolonged periods of spaceflight may develop a unique constellation of neuro-ocular findings termed Spaceflight Associated Neuro-Ocular Syndrome (SANS). SANS is a disorder that is unique to spaceflight and has no terrestrial equivalent. The prevalence of SANS increases with increasing spaceflight duration and although there have been residual, structural, ocular changes noted, no irreversible or permanent visual loss has occurred after SANS, with the longest spaceflight to date being 14 months. These microgravity-induced findings are being actively investigated by the United States' National Aeronautics Space Administration (NASA) and SANS is a potential obstacle to future longer duration, manned, deep space flight missions. The pathophysiology of SANS remains incompletely understood but continues to be a subject of intense study by NASA and others. The study of SANS is of course partially limited by the small sample size of humans undergoing spaceflight. Therefore, identifying a terrestrial experimental model of SANS is imperative to facilitate its study and for testing of preventative measures and treatments. Head-down tilt bed rest (HDTBR) on Earth has emerged as one promising possibility. In this paper, we review the HDTBR as an analog for SANS pathogenesis; the clinical and imaging overlap between SANS and HDTBR studies; and potential SANS countermeasures that have been or could be tested with HDTBR.
