RESUMO

BACKGROUND: New guidelines for managing cervical precancer among women in the United States use risk directly to guide clinical actions for individuals who are being screened. These risk-based management guidelines have previously only been based on risks from a large integrated healthcare system. We present here data representative of women of low income without continuous insurance coverage to inform the 2019 guidelines and ensure applicability. OBJECTIVE: We examined the risks of high-grade precancer after human papillomavirus and cytology tests in underserved women and assessed the applicability of the 2019 guidelines to this population. STUDY DESIGN: We examined cervical cancer screening and follow-up data among 363,546 women enrolled in the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program from 2009 to 2017. We estimated the immediate (prevalent) risks of cervical intraepithelial lesion grade 3 or cancer by using prevalence-incidence mixture models. Risks were estimated for each combination of human papillomavirus and cytology result and were stratified by screening history. We compared these risks with published estimates used in new risk-based management guidelines. RESULTS: Women who were up-to-date with their screening, defined as being screened with cytology within the past 5 years, had immediate risks of cervical intraepithelial neoplasia grade 3 or higher similar to that of women at Kaiser Permanente Northern California, whose data were used to develop the management guidelines. However, women in the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program had greater immediate risks if they were never screened or not up-to-date with their screening. CONCLUSION: New cervical risk-based management guidelines are applicable for underinsured and uninsured women with a low income in the United States who are up-to-date with their screening. The increased risk observed here among women who received human papillomavirus-positive, high-grade cytology results, who were never screened, or who were not up-to-date with their cervical cancer screening, led to a recommendation in the management guidelines for immediate treatment among these women.

RESUMO

OBJECTIVES: To estimate awardee-specific costs of delivering breast and cervical cancer screening services in their jurisdiction and to assess potential variation in the cost of key activities across awardees. METHODS: We developed the cost assessment tool to collect resource use and cost data from the National Breast and Cervical Cancer Early Detection Program awardees for 3 years between 2006 and 2010 and generated activity-based cost estimates. We estimated awardee-specific cost per woman served for all activities, clinical screening delivery services, screening promotion interventions, and overarching program support activities. RESULTS: The total cost per woman served by the awardees varied greatly from $205 (10th percentile) to $499 (90th percentile). Differences in the average (median) cost per person served for clinical services, health promotion interventions, and overarching support activities ranged from $51 to $125. CONCLUSIONS: The cost per woman served varied across awardee and likely reflected underlying differences across awardees in terms of screening infrastructure, population served, and barriers to screening uptake. Collecting information on contextual factors at the awardee, health system, provider, and individual levels may assist in understanding this variation in cost.

RESUMO

BACKGROUND: CD4+ T cells play an important role in atherosclerosis, but their antigen specificity is poorly understood. Immunization with apolipoprotein B (ApoB, core protein of low density lipoprotein) is known to be atheroprotective in animal models. Here, we report on a human APOB peptide, p18, that is sequence-identical in mouse ApoB and binds to both mouse and human major histocompatibility complex class II molecules. METHODS: We constructed p18 tetramers to detect human and mouse APOB-specific T cells and assayed their phenotype by flow cytometry including CD4 lineage transcription factors, intracellular cytokines, and T cell receptor activation. Apolipoprotein E-deficient ( Apoe-/-) mice were vaccinated with p18 peptide or adjuvants alone, and atherosclerotic burden in the aorta was determined. RESULTS: In human peripheral blood mononuclear cells from donors without cardiovascular disease, p18 specific CD4+ T cells detected by a new human leukocyte antigen-antigen D related-p18 tetramers were mostly Foxp3+ regulatory T cells (Tregs). Donors with subclinical cardiovascular disease as detected by carotid artery ultrasound had Tregs coexpressing retinoic acid-related orphan receptor gamma t or T-bet, which were both almost absent in donors without cardiovascular disease. In Apoe-/- mice, immunization with p18 induced Tregs and reduced atherosclerotic lesions. After peptide restimulation, responding CD4+ T cells identified by Nur77-GFP (green fluorescent protein) were highly enriched in Tregs. A new mouse I-Ab-p18 tetramer identified the expansion of p18-specific CD4+ T cells on vaccination, which were enriched for interleukin-10-producing Tregs. CONCLUSIONS: These findings show that APOB p18-specific CD4+ T cells are mainly Tregs in healthy donors, but coexpress other CD4 lineage transcription factors in donors with subclinical cardiovascular disease. This study identifies ApoB peptide 18 as the first Treg epitope in human and mouse atherosclerosis.

RESUMO

BACKGROUND: Diet is an important contributor to risk of cardiovascular disease (CVD) and integral in management and delaying progression. Little is known however about whether increased CVD risk or established CVD has any influence on dietary intakes of Australian adults or children residing in the same household. This study aimed to determine whether the presence of CVD or CVD risk factors influences dietary intake of Australian adults and if the presence of an adult with increased CVD risk influences the dietary intake of a child living in the same household. METHODS: Data were sourced from the 2011-2013 Australian Health Survey for: (1) adults ≥18 years with risk factors or established CVD and (2) children 2-17 years residing in the same household as adults with CVD risk factors or established CVD. Selected nutrient intakes (total fat, saturated fat plus trans fat, alpha-linolenic acid, total long chain omega 3 fatty acids, fibre and sodium) collected by repeated 24 h recalls were compared to national dietary recommendations and to the intakes of all other adults and children surveyed. Standard errors of the estimates were calculated using the replicate weights method, and an alpha value of <0.05 considered statistically significant. RESULTS: Six thousand two hundred sixty five of 9435 adults surveyed were identified as having CVD risk factors or established disease and of these 1609 had a child in the same household that also contributed data in this survey. No differences were observed in adjusted mean dietary intakes between those without risk factors or established CVD and those with, except for total energy and sodium which were significantly lower in the adults with CVD risk factors and/or established disease. However sodium intakes across both groups were higher than recommended targets. There were no differences for selected nutrients between children residing with affected adults and other children surveyed. CONCLUSIONS: While intakes of Australian adults with CVD risk factors or established disease were favourable for sodium, compared to unaffected adults, there is still scope for improvement as many Australian adults, despite CVD risk, are unable to achieve targets for selected nutrients. Effective dietary behaviour change strategies and resources are urgently needed.

RESUMO

Breast and cervical cancer have had disparate impact on the lives of women. The burden of breast and cervical cancer is more prominent among some racial and ethnic minority women. Providing comprehensive care to all medically underserved women is a critical element in continuing the battle to reduce cancer burden and eliminate disparities. The National Breast and Cervical Cancer Early Detection Program is the only nationally organized cancer screening program for underserved women in the United States. Its public health goal is to ensure access to high-quality screening, follow-up, and treatment services for diverse and vulnerable populations that, in turn, may reduce disparities.

RESUMO

PURPOSE: With little scientific evidence to support use of aromatherapy for postoperative nausea and/or vomiting (PONV) symptoms, this study evaluated controlled breathing with peppermint aromatherapy (AR) and controlled breathing alone (CB) for PONV relief. DESIGN: A single blind randomized control trial design was used. METHODS: On initial PONV complaint, symptomatic subjects received either CB (n = 16) or AR (n = 26) intervention based on randomization at enrollment. A second treatment was repeated at 5 minutes if indicated. Final assessment occurred 10 minutes post initial treatment. Rescue medication was offered for persistent symptoms. FINDINGS: Among eligible subjects, PONV incidence was 21.4% (42/196). Gender was the only risk factor contributing to PONV symptoms (P = .0024). Though not statistically significant, CB was more efficacious than AR, 62.5% versus 57.7%, respectively. CONCLUSIONS: CB can be initiated without delay as an alternative to prescribed antiemetics. Data also support use of peppermint AR in conjunction with CB for PONV relief.

RESUMO

BACKGROUND: Preterm human milk-fed infants often experience suboptimal growth despite the use of human milk fortifier (HMF). The extra protein supplied in fortifiers may be inadequate to meet dietary protein requirements for preterm infants. OBJECTIVE: We assessed the effect of human milk fortified with a higher-protein HMF on growth in preterm infants. DESIGN: This is a randomized controlled trial in 92 preterm infants born at <31 wk gestation who received maternal breast milk that was fortified with HMF containing 1.4 g protein/100 mL (higher-protein group) or 1.0 g protein/100 mL (current practice) until discharge or estimated due date, whichever came first. The HMFs used were isocaloric and differed only in the amount of protein or carbohydrate. Length, weight, and head-circumference gains were assessed over the study duration. RESULTS: Length gains did not differ between the higher- and standard-protein groups (mean difference: 0.06 cm/wk; 95% CI: -0.01, 0.12 cm/wk; P = 0.08). Infants in the higher-protein group achieved a greater weight at study end (mean difference: 220 g; 95% CI: 23, 419 g; P = 0.03). Secondary analyses showed a significant reduction in the proportion of infants who were less than the 10th percentile for length at the study end in the higher-protein group (risk difference: 0.186; 95% CI: 0.370, 0.003; P = 0.047). CONCLUSIONS: A higher protein intake results in less growth faltering in human milk-fed preterm infants. It is possible that a higher-protein fortifier than used in this study is needed. This trial was registered with the Australian New Zealand Clinical Trials Registry (http://www.anzctr.org.au/) as ACTRN12606000525583.

RESUMO

BACKGROUND: The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides breast cancer screening to medically underserved, low-income women aged 40-64 years. No study has evaluated NBCCEDP's effect on breast cancer mortality. PURPOSE: This study estimates life-years saved by NBCCEDP breast cancer screening compared with screening in the absence of NBCCEDP and with no screening. METHODS: A breast cancer simulation model based on existing Cancer Intervention and Surveillance Modeling Network models was constructed. The screening module from these models was modified to reflect screening frequency for NBCCEDP participants. Screening data for uninsured women represented what would have happened without the program. Separate simulations were performed for women who received NBCCEDP (Program) screening, women who potentially received screening without the program (No Program), and women who received no screening (No Screening). The impact of NBCCEDP was estimated as the difference in life-years between the Program and No Program, and the Program and No Screening scenarios. The analysis was performed in 2008-2009. RESULTS: Among 1.8 million women who were screened between 1991 and 2006, the Program saved 100,800 life-years compared with No Program and 369,000 life-years compared with No Screening. Per woman screened, the Program saved 0.056 life-years (95% CI=0.031, 0.081) compared with No Program and 0.206 life-years (95% CI=0.177, 0.234) compared with No Screening. Per woman with invasive breast cancer and screen-detected invasive cancer, the Program saved 0.41 and 0.71 life-years, respectively, compared with No Program. CONCLUSIONS: These estimates suggest that NBCCEDP breast cancer screening has reduced mortality among medically uninsured and underinsured low-income women.

RESUMO

BACKGROUND: Head lice move easily from head to head. The lack of safe, effective repellents leads to reinfestation. OBJECTIVES: To test the efficacy of a slow-release citronella formulation as a repellent against the head louse. METHODS: During 4 months in 2003 a randomized, placebo-controlled double-blind clinical study was conducted in four elementary schools; 103 children were treated with the test formulation and 95 with a placebo. RESULTS: A significant difference was observed during the second examination 2 months later, when 12.0% of the children treated with the test repellent and 50.5% of those treated with placebo were infested with lice. A significant difference was also observed at the third examination 2 months later, when 12.4% of the children treated with the test repellent and 33.7% treated with placebo were infested. Overall, there were significant differences between those treated with the repellent and those treated with the placebo (15.4% and 55.1% respectively, P < 0.0001). Side effects were observed in 4.4% of children who disliked the odor of the formulation, and an additional 1.0% who complained of a slight itching and burning sensation. CONCLUSIONS: Use of an effective repellent could significantly lower the incidence of reinfestations, which would lower expenditure on lice control, including pediculicides, combs and products for nit removal, and the time spent on treatment and removal of the nits.

RESUMO

BACKGROUND: Head louse infestations are prevalent worldwide. Over the past 20-25 years, 15-20% of all children in Israel between 4 and 13 years of age have been infested with head lice. This is mainly due to the existence of ineffective pediculicides on the market. OBJECTIVE: To examine the pediculicidal efficacy and safety of a natural remedy ("Chick-Chack") and to compare it in an open clinical study with a known pesticide spray. METHODS: The natural remedy, which contains coconut oil, anise oil and ylang ylang oil, was applied to the hair of infested children three times at 5 day intervals. Each treatment lasted for 15 minutes. The control pediculicide was a spray formulation containing permethrin, malathion, piperonyl butoxide, isododecane and propellant gas, which was applied twice for 10 minutes with a 10 day interval between applications. RESULTS: Of 940 children, aged 6-14 years, from six schools in Jerusalem who were examined for head louse infestation, 199 (21.2%) were infested with lice and eggs, while 164 (17.4%) were infested only with nits. Altogether, 119 children were randomly treated with either the natural remedy or the control product. Treatment was successful with the natural remedy in 60 children (92.3%) and with the control pediculicide in 59 children (92.2%). There were no significant side effects associated with either formulation. CONCLUSIONS: The natural remedy was very effective in controlling louse infestations under clinical conditions and caused no serious side effects.
