ABSTRACT

Ovarian teratomas are found in one-third of females presenting with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. When a teratoma is detected on imaging, its removal is first-line therapy. Even with multiple imaging modalities, occasionally, the teratoma is found only on subsequent imaging, long after initial presentation. Very rarely, patients have undergone oophorectomy despite negative imaging, with pathology demonstrating teratoma, and resulting clinical improvement. We present a patient in whom removal of a teratoma, not visible on conventional imaging, resulted in marked clinical improvement. Such cases present a major clinical challenge, needing to consider the risks of oophorectomy, including sterilisation and early menopause, versus the possibility of death in the absence of response to first-line (eg, corticosteroids, plasma exchange, intravenous immunoglobulin), second-line (eg, rituximab) and third-line (eg, bortezomib) immunosuppression. This decision is made more difficult as patients are usually females of childbearing age who at the time lack capacity to make medical decisions. This case also highlights the lack of consensus and guidelines for imaging modalities used to detect teratoma and when to pursue oophorectomy.

ABSTRACT

Infections caused by Salmonella serovars are the leading cause of foodborne hospitalizations and deaths in Americans, extensively prevalent worldwide, and pose a considerable financial burden on public health infrastructure and private manufacturing. While a comprehensive review is lacking for delineating the role of dietary components on prevention of Salmonellosis, evidence for the role of diet for preventing the infection and management of Salmonellosis symptoms is increasing. The current study is an evaluation of preclinical and clinical studies and their underlying mechanisms to elaborate the efficacy of bioactive dietary components for augmenting the prevention of Salmonella infection. Studies investigating dietary components such as fibers, fatty acids, amino acids, vitamins, minerals, phenolic compounds, and probiotics exhibited efficacy of dietary compounds against Salmonellosis through manipulation of host bile acids, mucin, epithelial barrier, innate and adaptive immunity and gut microbiota as well as impacting the cellular signaling cascades of the pathogen. Pre-clinical studies investigating synergism and/or antagonistic activities of various bioactive compounds, additional randomized clinical trials, if not curtailed by lack of equipoise and ethical concerns, and well-planned epidemiological studies could augment the development of a validated and evidence-based guideline for mitigating the public health burden of human Salmonellosis through dietary compounds.

ABSTRACT

Previously known as Enterobacter sakazakii from 1980 to 2007, Cronobacter sakazakii is an opportunistic bacterium that survives and persists in dry and low-moisture environments, such as powdered infant formula. Although C. sakazakii causes disease in all age groups, infections caused by this pathogen are particularly fatal in infants born premature and those younger than two months. The pathogen has been isolated from various environments such as powdered infant formula manufacturing facilities, healthcare settings, and domestic environments, increasing the chance of infection through cross-contamination. The current study discusses the outbreak history of C. sakazakii and the ability of the microorganism to produce biofilms on biotic and abiotic surfaces. The study further discusses the fate of the pathogen in low-moisture environments, articulates preventive measures for healthcare providers and nursing parents, and delineates interventions that could be utilized in infant formula manufacturing to minimize the risk of contamination with Cronobacter sakazakii.

ABSTRACT

Latinos have the highest US childhood uninsurance rate of any race/ethnicity, but little is known about effective ways to eliminate this disparity. We evaluated the effects of parent mentors-Latino parents with children covered by Medicaid or the Children's Health Insurance Program-on insuring Latino children in a randomized, controlled, community-based trial of 155 uninsured children conducted in the period 2011-15. Parent mentors were trained to assist families in getting insurance coverage, accessing health care, and addressing social determinants of health. We found that parent mentors were more effective than traditional methods in insuring children (95 percent versus 69 percent), achieving faster coverage and greater parental satisfaction, reducing unmet health care needs, providing children with primary care providers, and improving the quality of well-child and subspecialty care. Children in the parent-mentor group had higher quality of overall and specialty care, lower out-of-pocket spending, and higher rates of coverage two years after the end of the intervention (100 percent versus 70 percent). Parent mentors are highly effective in insuring uninsured Latino children and eliminating disparities.

ABSTRACT

BACKGROUND: More than 48% of U.S. children are racial/ethnic minorities, 21% are poor, and 6% are uninsured. It is unclear, however, what methods are most effective for identifying and engaging community partners in study enrollment of these children in high-risk communities. OBJECTIVE: Evaluate a new methodological approach to the screening, identification, and intervention study enrollment of uninsured minority children. METHODS: We developed, implemented, and evaluated a methodological approach consisting of four components: (1) identify communities with the highest proportions of low-income minority families with uninsured children, (2) hire minority research staff responsible for community engagement and data collection, (3) implement and evaluate a parent mentor (PM) intervention built on community partnerships and which creates jobs, and (4) successfully execute the research by engaging appropriate community partners. RESULTS: PMs were successfully recruited (n = 15) and trained (test scores significantly improved). Large numbers (n = 97) of appropriate, diverse community partners were engaged.The most productive community partners for recruitment were schools and childcare establishments, community-based organizations, discount and niche stores, supermarkets, and churches. Community partnerships resulted in 49,631 candidate participants screened and 329 enrolled in the study. The intervention was highly successful, with PMs significantly more effective and faster than traditional outreach/enrollment in insuring uninsured minority children, sustaining coverage, improving care access, reducing out-of-pocket costs, and achieving parental satisfaction and care quality, while saving $6,045 per child insured per year. CONCLUSIONS: This innovative, community-based methodology is highly effective, and could prove useful for community-based interventions targeting a variety of childhood and adult health, health-care, and equity issues.

ABSTRACT

BACKGROUND: Of the 4.8 million uninsured children in America, 62-72% are eligible for but not enrolled in Medicaid or CHIP. Not enough is known, however, about the impact of health insurance on outcomes and costs for previously uninsured children, which has never been examined prospectively. METHODS: This prospective observational study of uninsured Medicaid/CHIP-eligible minority children compared children obtaining coverage vs. those remaining uninsured. Subjects were recruited at 97 community sites, and 11 outcomes monitored monthly for 1 year. RESULTS: In this sample of 237 children, those obtaining coverage were significantly (P < .05) less likely than the uninsured to have suboptimal health (27% vs. 46%); no PCP (7% vs. 40%); experienced never/sometimes getting immediate care from the PCP (7% vs. 40%); no usual source of preventive (1% vs. 20%) or sick (3% vs. 12%) care; and unmet medical (13% vs. 48%), preventive (6% vs. 50%), and dental (18% vs. 62%) care needs. The uninsured had higher out-of-pocket doctor-visit costs (mean = $70 vs. $29), and proportions of parents not recommending the child's healthcare provider to friends (24% vs. 8%) and reporting the child's health caused family financial problems (29% vs. 5%), and lower well-child-care-visit quality ratings. In bivariate analyses, older age, birth outside of the US, and lacking health insurance for >6 months at baseline were associated with remaining uninsured for the entire year. In multivariable analysis, children who had been uninsured for >6 months at baseline (odds ratio [OR], 3.8; 95% confidence interval [CI], 1.4-10.3) and African-American children (OR, 2.8; 95% CI, 1.1-7.3) had significantly higher odds of remaining uninsured for the entire year. Insurance saved $2886/insured child/year, with mean healthcare costs = $5155/uninsured vs. $2269/insured child (P = .04). CONCLUSIONS: Providing health insurance to Medicaid/CHIP-eligible uninsured children improves health, healthcare access and quality, and parental satisfaction; reduces unmet needs and out-of-pocket costs; and saves $2886/insured child/year. African-American children and those who have been uninsured for >6 months are at greatest risk for remaining uninsured. Extrapolation of the savings realized by insuring uninsured, Medicaid/CHIP-eligible children suggests that America potentially could save $8.7-$10.1 billion annually by providing health insurance to all Medicaid/CHIP-eligible uninsured children.

ABSTRACT

BACKGROUND: Recruiting and retaining minority participants in clinical trials continue to be major challenges. Although multiple studies document lower minority trial enrollment, much less is known about effective minority retention strategies. Our objectives were to evaluate an innovative approach to high RCT retention of minority children, and identify child/caregiver characteristics predicting attrition. METHODS: The Kids' HELP trial examined the effects of Parent Mentors on insuring uninsured minority children. We tested a retention strategic framework consisting of: 1) optimizing cultural/linguistic competency; 2) staff training on participant relationships and trust; 3) comprehensive participant contact information; 4) an electronic tracking database; 5) reminders for upcoming outcomes-assessment appointments; 6) frequent, sustained contact attempts for non-respondents; 7) financial incentives; 8) individualized rapid-cycle quality-improvement approaches to non-respondents; 9) reinforcing study importance; and 10) home assessment visits. We compared attrition in Kids' HELP vs. two previous RCTs in similar populations, and conducted bivariate and multivariable analyses of factors associated with Kids' HELP attrition. RESULTS: Attrition in Kids' HELP was lower than in two similar RCTs, at 10.9% vs. 37% and 40% (P <0.001). After multivariable adjustment, missing the first outcomes follow-up assessment was the only factor significantly associated with attrition (relative risk=1.5; 95% confidence interval, 1.1-2.0). CONCLUSIONS: A retention strategic framework was successful in minimizing attrition in minority, low-income children. Participants missing first assessment appointments were at highest risk of subsequent attrition. These findings suggest that deploying this framework may help RCT retention of low-income minority children, particularly those at the highest risk of subsequent attrition.

ABSTRACT

BACKGROUND: Six million US children are uninsured, despite two-thirds being eligible for Medicaid/Children's Health Insurance Program (CHIP), and minority children are at especially high risk. The most effective way to insure uninsured children, however, is unclear. METHODS: We conducted a randomized trial of the effects of parent mentors (PMs) on insuring uninsured minority children. PMs were experienced parents with ≥1 Medicaid/CHIP-covered child who received 2 days of training, then assisted families for 1 year with insurance applications, retaining coverage, medical homes, and social needs; controls received traditional Medicaid/CHIP outreach. The primary outcome was obtaining insurance 1 year post-enrollment. RESULTS: We enrolled 237 participants (114 controls; 123 in PM group). PMs were more effective (P< .05 for all comparisons) than traditional methods in insuring children (95% vs 68%), and achieving faster coverage (median = 62 vs 140 days), high parental satisfaction (84% vs 62%), and coverage renewal (85% vs 60%). PM children were less likely to have no primary care provider (15% vs 39%), problems getting specialty care (11% vs 46%), unmet preventive (4% vs 22%) or dental (18% vs 31%) care needs, dissatisfaction with doctors (6% vs 16%), and needed additional income for medical expenses (6% vs 13%). Two years post-PM cessation, more PM children were insured (100% vs 76%). PMs cost $53.05 per child per month, but saved $6045.22 per child insured per year. CONCLUSIONS: PMs are more effective than traditional Medicaid/CHIP methods in insuring uninsured minority children, improving health care access, and achieving parental satisfaction, but are inexpensive and highly cost-effective.

ABSTRACT

BACKGROUND: Minority children have the highest US uninsurance rates; Latino and African-American children account for 53 % of uninsured American children, despite comprising only 48 % of the total US child population. The study aim was to examine parental awareness of and the reasons for lacking health insurance in Medicaid/CHIP-eligible minority children, and the impact of the children's uninsurance on health, access to care, unmet needs, and family financial burden. METHODS: For this cross-sectional study, a consecutive series of uninsured, Medicaid/CHIP-eligible Latino and African-American children was recruited at 97 urban Texas community sites, including supermarkets, health fairs, and schools. Measures/outcomes were assessed using validated instruments, and included sociodemographic characteristics, uninsurance duration, reasons for the child being uninsured, health status, special healthcare needs, access to medical and dental care, unmet needs, use of health services, quality of care, satisfaction with care, out-of-pocket costs of care, and financial burden. RESULTS: The mean time uninsured for the 267 participants was 14 months; 5 % had never been insured. The most common reason for insurance loss was expired and never reapplied (30 %), and for never being insured, high insurance costs. Only 49 % of parents were aware that their uninsured child was Medicaid/CHIP eligible. Thirty-eight percent of children had suboptimal health, and 2/3 had special healthcare needs, but 64 % have no primary-care provider; 83 % of parents worry about their child's health more than others. Unmet healthcare needs include: healthcare, 73 %; mental healthcare, 70 %; mobility aids/devices, 67 %; dental, 61 %; specialty care, 57 %; and vision, 46 %. Due to the child's health, 35 % of parents had financial problems, 23 % cut work hours, and 10 % ceased work. Higher proportions of Latinos lack primary-care providers, and higher proportions of African-Americans experience family financial burden. CONCLUSIONS: Half of parents of uninsured minority children are unaware that their children are Medicaid/CHIP-eligible. These uninsured children have suboptimal health, impaired access to care, and major unmet needs. The child's health causes considerable family financial burden, and one in 10 parents ceased work. The study findings indicate urgent needs for better parental education about Medicaid/CHIP, and for improved Medicaid/CHIP outreach and enrollment.

ABSTRACT

OBJECTIVE: Seven million US children lack health insurance. Community health workers are effective in insuring uninsured children, and parent mentors (PMs) in improving asthmatic children's outcomes. It is unknown, however, whether a training program can result in PMs acquiring knowledge/skills to insure uninsured children. The study aim was to determine whether a PM training program results in improved knowledge/skills regarding insuring uninsured minority children. METHODS: Minority parents in a primary-care clinic who already had Medicaid/Children's Health Insurance Program (CHIP)-covered children were selected as PMs, attending a 2-day training session addressing 9 topics. A 33-item pretraining test assessed knowledge/skills regarding Medicaid/CHIP, the application process, and medical homes. A 46-item posttest contained the same 33 pretest items (ordered differently) and 13 Likert-scale questions on training satisfaction. RESULTS: All 15 PMs were female and nonwhite, 60% were unemployed, and the mean annual income was $20,913. After training, overall test scores (0-100 scale) significantly increased, from a mean of 62 (range 39-82) to 88 (range 67-100) (P < .01), and the number of wrong answers decreased (mean reduction 8; P < .01). Significant improvements occurred in 6 of 9 topics, and 100% of PMs reported being very satisfied (86%) or satisfied (14%) with the training. Preliminary data indicate PMs are significantly more effective than traditional Medicaid/CHIP outreach/enrollment in insuring uninsured minority children. CONCLUSIONS: A PM training program resulted in significant improvements in knowledge and skills regarding outreach to and enrollment of uninsured, Medicaid/CHIP-eligible children, with high levels of satisfaction with the training. This PM training program might be a useful model for training Patient Protection and Affordable Care Act navigators.

ABSTRACT

BACKGROUND & OBJECTIVES: Six million US children have no health insurance, and substantial racial/ethnic disparities exist. The design, methods, and baseline characteristics are described for Kids' Health Insurance by Educating Lots of Parents (Kids' HELP), the first randomized, clinical trial of the effectiveness of Parent Mentors (PMs) in insuring uninsured minority children. METHODS & RESEARCH DESIGN: Latino and African-American children eligible for but not enrolled in Medicaid/CHIP were randomized to PMs, or a control group receiving traditional Medicaid/CHIP outreach. PMs are experienced parents with ≥1 Medicaid/CHIP-covered children. PMs received two days of training, and provide intervention families with information on Medicaid/CHIP eligibility, assistance with application submission, and help maintaining coverage. Primary outcomes include obtaining health insurance, time interval to obtain coverage, and parental satisfaction. A blinded assessor contacts subjects monthly for one year to monitor outcomes. RESULTS: Of 49,361 candidates screened, 329 fulfilled eligibility criteria and were randomized. The mean age is seven years for children and 32 years for caregivers; 2/3 are Latino, 1/3 are African-American, and the mean annual family income is $21,857. Half of caregivers were unaware that their uninsured child is Medicaid/CHIP eligible, and 95% of uninsured children had prior insurance. Fifteen PMs completed two-day training sessions. All PMs are female and minority, 60% are unemployed, and the mean annual family income is $20,913. Post-PM-training, overall knowledge/skills test scores significantly increased, and 100% reported being very satisfied/satisfied with the training. CONCLUSIONS: Kids' HELP successfully reached target populations, met participant enrollment goals, and recruited and trained PMs.

ABSTRACT

This study evaluates the potential of ellagic acid (EA) as an enhancer of radiation-induced apoptosis in cancer cells. HeLa cells treated with EA and gamma radiation showed increased superoxide generation, upregulated p53 protein expression, and decreased antioxidant enzymes. We also found that EA and radiation enhance capase-3 activity via oxidative stress, increased intracellular calcium levels, and phospholipase C and cause a drop in mitochondrial potential. These results might provide a basis for prominent reduction of cancer cell using EA as an adjunct to radiotherapy and an opportunity to lower the toxic radiation doses to improve the quality of life.
