RESUMO

Colorectal cancer (CRC) is a leading cause of cancer death in the USA. Screening programs in federally qualified health centers (FQHCs) are essential to reducing CRC-related mortality and morbidity among underserved populations. Centralized, population-based mailed fecal immunochemical test (FIT) programs can improve CRC screening rates, but barriers to implementation remain. We qualitatively explored barriers and facilitators to implementation of a mailed FIT program at a large, urban FQHC that employed advance notification "primers" (live calls and texts) and automated reminders. We interviewed 25 patients and 45 FQHC staff by telephone about their experience with the program. Interviews were transcribed, coded, and content analyzed using NVivo.12. Patients and staff found advance notifications conveyed through live phone calls or text messages to be acceptable and motivational for FIT completion. Live phone primers were helpful in addressing patients' questions and misconceptions about screening, particularly for patients new to screening. Advance notifications sent by text were considered timely and useful in preparing patients for receipt of the FIT. Barriers to implementation included lack of receipt of primers, reminders, or the mailed FIT itself due to inaccurate patient contact information within the FQHC medical record; lack of systems for documenting mailed FIT outreach to coordinate with clinical care; and lack of local caller identification for primers and reminders. Our findings demonstrate that an enhanced mailed FIT program using primers and reminders was acceptable. Our findings can help other FQHCs implement and optimize their mailed FIT programs.

RESUMO

BACKGROUND: All families experience financial and time costs related to caring for their children's health. Understanding the economic burden faced by families of children with chronic health conditions (CHC) is crucial for designing effective policies to support families. METHODS: In this prospective study we used electronic health records to identify children between 3 and 17 years old with autism spectrum disorder (ASD), asthma, or neither (control) from three Kaiser Permanente regions and several community health centers in the OCHIN network. We oversampled children from racial and ethnic minority groups. Parent/guardian respondents completed surveys three times, approximately four months apart. The surveys included the Family Economic Impact Inventory (measuring financial, time, and employment costs of caring for a child's health), and standardized measures of children's quality of life, behavioral problems, and symptom severity for children with ASD or asthma. We also assessed parenting stress and parent physical and mental health. All materials were provided in English and Spanish. RESULTS: Of the 1,461 families that enrolled (564 ASD, 468 asthma, 429 control), children were predominantly male (79%), with a mean age of 9.0 years, and racially and ethnically diverse (43% non-Hispanic white; 22% Hispanic; 35% Asian, Black, Native Hawaiian, or another race/ethnicity). The majority of survey respondents were female (86%), had a college degree (62%), and were married/partnered (79%). ASD group respondents were less likely to be employed (73%) than those in the asthma or control groups (both 80%; p = .023). Only 32% of the control group reported a household income ≤ $4,000/month compared with 41% of asthma and 38% of ASD families (p = .006). CONCLUSIONS: Utilizing a novel measure assessing family economic burden, we successfully collected survey responses from a large and diverse sample of families. Drawing upon the conceptual framework, survey measures, and self-report data described herein we will conduct future analyses to examine the economic burdens related to CHC and the incremental differences in these burdens between health groups. This information will help policy makers to design more equitable health and social policies that could reduce the burden on families.

RESUMO

Programs that directly mail fecal immunochemical tests (FIT) to patients can increase colorectal cancer (CRC) screening, especially in low-income and Latino populations. Few studies have explored patient reactions to prompts or reminders that accompany such programs. As part of the Participatory Research to Advance Colon Cancer Prevention pilot study, which tested prompts and reminders to a direct-mail FIT program in a large, urban health center, we conducted telephone interviews among English- and Spanish-speaking participants who were assigned to receive a series of text message prompts, automated phone call reminders, and/or live phone call reminders. We analyzed interviews using a qualitative content analysis approach. We interviewed 41 participants, including 25 responders (61%) and 16 nonresponders (39%) to the direct-mail program. Participants appreciated program ease and convenience. Few participants recalled receiving prompts or automated/live reminders; nevertheless, the vast majority (95%, n = 39) thought reminders were acceptable and helpful and suggested that 2-3 reminders delivered starting 1 week after the mailed FIT would optimally encourage completion. Prompts and reminders used with mailed-FIT programs are accepted by patients, and my help boost response rates.

RESUMO

Hispanic women are at high risk for type 2 diabetes (T2D), with obesity and unhealthy eating being important contributing factors. A cross-sectional design was used in this study to identify dietary patterns and their associations with diabetes risk factors. Participants completed a culturally adapted Food Frequency Questionnaire capturing intake over the prior 3 months. Overweight/obese Hispanic women (n = 191) with or at risk for T2D were recruited from a community clinic into a weight loss intervention. Only baseline data was used for this analysis. Dietary patterns and their association with diabetes risk factors (age, body mass index, abdominal obesity, elevated fasting blood glucose [FBG], and hemoglobin A1c). An exploratory factor analysis of dietary data adjusted for energy intake was used to identify eating patterns, and Pearson correlation coefficient (r) to assess the association of the eating patterns with the diabetes risk factors. Six meaningful patterns with healthful and unhealthful traits emerged: (1) sugar and fat-laden, (2) plant foods and fish, (3) soups and starchy dishes, (4) meats and snacks, (5) beans and grains, and (6) eggs and dairy. Scores for the "sugar and fat-laden" and "meats and snacks" patterns were negatively associated with age (r = - 0.230, p = 0.001 and r = - 0.298, p < 0.001, respectively). Scores for "plant foods and fish" were positively associated with FBG (r = 0.152, p = 0.037). Being younger may be an important risk factor for a diet rich in sugar and fat; this highlights the need to assess dietary patterns among younger Hispanic women to identify traits potentially detrimental for their health.

RESUMO

BACKGROUND: Overweight Hispanic women are at high risk for type 2 diabetes. A clinical diagnosis of hyperglycemia is often necessary to access interventions. We examined the prevalence of undiagnosed hyperglycemia among a group of low-income overweight or obese Hispanic women, who were receiving care at a Federally Qualified Health Center (FQHC). METHODS: Among 196 overweight or obese Hispanic women (mean age 44 ± 10 years, mean weight 86.8 ± 16.5 kg, mean body mass index [BMI] 36.5 ± 6.4 kg/m2) enrolled in a randomized clinical weight-loss trial, we compared A1C and fasting blood glucose (FBG) obtained at baseline with women's existing diabetes and prediabetes diagnoses in the medical record. RESULTS: According to the information in participants' medical records, 36% (70/196) had diagnosed diabetes, 20% (39/196) had a diagnosis of prediabetes, and the remaining 44% (87/196) had neither diagnosis. Among participants without a diagnosis of diabetes or prediabetes during the baseline screening for our study, 63% (55/87) had at least one test in the prediabetes range (baseline A1C and FBG were in prediabetes range for 39 and 55 participants, respectively), and 13% (11/87) had at least one test in the diabetic range (baseline A1C and FBG values in diabetes range for 3 and 11 participants, respectively). DISCUSSION: We found substantial prevalence of undiagnosed hyperglycemia among a sample of overweight and obese Hispanic women. It is possible that limited awareness of diabetes risk may be a barrier to patient compliance with screening recommendations.

RESUMO

In a simulated post process contamination scenario liquid smoke was sprayed on the frankfurters after peeling, and then inoculated with Listeria monocytogenes (Lm). Samples that did not receive a liquid smoke spray remained at approximately 2 log cfu/cm(2) during the 48h of storage while the levels on the liquid smoke treated frankfurters continued to decline until they were below detection level (1 cfu/100 cm(2)). A shelf-life study lasting 140 days indicated that liquid smoke suppressed the growth of Lm for up to 130 days. An application of 2 or 3 ml liquid smoke at packaging resulted in at least a 1 log reduction of Lm within 12h post packaging.

RESUMO

Silymarin encompasses a group of flavonolignans that are extracted from Silybum marianum (Asteraceae) fruits. The silymarins have previously been reported to lower low-density lipoprotein (LDL) levels associated with high-fat diets. The present study reports the efficacy of the silymarins in inhibiting oxidized low-density lipoprotein (oxLDL) generation and subsequent scavenger receptor (SR) mediated monocyte adherence to oxLDL. The flavonolignans that comprise silymarin include silichristin (SC), silidianin (SD), silibinin (SBN), and isosilibinin (IS). These flavonolignans (300 microM) lowered oxLDL generation, measured by the thiobarbituric acid-reacting substances (TBARS) assay, by 60.0, 28.1, 60.0, and 30.1%, respectively. SBN treatment of LDL in the presence of copper sulfate (CuSO 4) resulted in a significant dose-dependent inhibition of monocyte adhesion. Inhibition was paralleled by a decrease in binding of anti-oxLDL antibodies recognized by U937 monocyte Fc gamma receptors (FcgammaR). These results showed that silymarin and SBN, likely through antioxidant and free radical scavenging mechanisms of action, inhibit the generation of oxLDL and oxidation-specific neoepitopes recognized by SR and FcgammaR expressed on monocytes/macrophages.

RESUMO

Milk thistle (Silybum marianum L.) seed meal is extracted for the flavonolignans, silychristin, silydianin, silybinin A, silybinin B, isosilybinin A and isosilybinin B, which are collectively known as the silymarin complex. To obtain the flavonolignans, the meal is usually treated with successive washes of petroleum ether to remove the lipids, followed by extraction of the flavonolignans with ethanol. This work examines the possible replacement of petroleum ether and ethanol by water or other aqueous solutions in these processes. To replace petroleum ether, pretreatments with 1.2% NaOH (w/w), 1.5% H2SO4 (w/w), 2% NaHCO3 (w/w), 0.14% cellulase and water were investigated. Of these pretreatments, 1.5% H2SO4 and water produced similar flavonolignan yields as petroleum ether. Results established that pretreating the milk thistle seed meal with 1.5% H2SO4 (w/w) at 50 degrees C for 18 h could replace the petroleum ether pretreatment. In addition, it was shown that similar amounts of flavonolignan could be recovered with a 1.5% H2SO4/water (100 degrees C) extraction as with a petroleum ether/ethanol extraction. Although cellulase pretreatment was not examined extensively, significant advances in cellulase effectiveness and cost have occurred in the past few years by companies such as Genencor International and Novozymes. These advances should help to make enzyme use for cellulose conversion, as well as extraction pretreatment, technically and economically feasible.

RESUMO

Silybum marianum contains flavonolignans, termed silymarin (SM), that are therapeutic agents for many inflammation-based diseases including atherosclerosis. Oxidation of human low-density lipoprotein was induced by CuSO4 or J774 macrophage cells and measured by the formation of thiobarbituric acid reactive substances (TBARS). SM was extracted by pressurized hot water (PHWE) or ethanol, and the effects of these extracts on TBARS formation were evaluated in comparison with those of SM preparations made from blending masses of individual flavonolignan standards in ratios identical to those of the water and ethanol extracts. Ethanol-extracted SM and its blended counterpart inhibited the generation of TBARS by 82% and 43%, respectively, at 150 mumol/L doses. TBARS levels in the presence of 150 micromol/L of the PHWE and its blended SM counterpart were reduced by 84% and 38%, respectively. Extracts from milk thistle fruit displayed higher protective effects than blended SM solutions of the same concentration with an identical compositional makeup. The appearance of degradation peaks in the water extract did not create any cytotoxic effects. Results of this study confirm that PHWE can be used to extract flavonolignans from milk thistle and that these extracts may possess therapeutic potential different from or beyond that of traditional organic solvent preparations.

RESUMO

High-value phytochemicals could be extracted from biomass prior to the current cellulosic pretreatment technologies (i.e., lime, ammonia, dilute acid, or pressurized hot water treatments) provided that the extraction is performed with a solvent that is compatible with the pretreatment. This work reports on the extraction of flavonoids from Albizia julibrissin biomass. While extracting A. julibrissin foliage with 50 degrees C water, 2.227 mg/g of hyperoside and 8.134 mg/g quercitrin were obtained, which is in the realm of what was obtained with 60% methanol. A. julibrissin foliage, flower, and whole plant extracts were tested in terms of their potential to inhibit low-density lipoprotein (LDL) oxidization. The highest inhibition was obtained with foliage water extracts, which were standardized at 2.5 microM of flavonoids. Also, the 2.5 microM foliage water extract resulted in a reduction from 43% to only 1% of the observed monocyte adherence. To have commercial application, A. julibrissin water extracts should be devoid of toxicity. The A. julibrissin foliage, flower, and whole plant water extracts were not toxic to Vero 76 cells. In summary, A. julibrissin biomass can be extracted with 50 degrees C water to yield an antioxidant stream, showing that it may be possible to couple extraction of valuable phytochemicals to the cellulosic pretreatment step.
