Dietary factors and cancers of breast, endometrium, and ovary: Strategies for modifying fat intake in African American women

Modification of dietary fat and fiber could help prevent cancers of the breast, endometrium, and ovary that are prevalent in African-American women. Dietary intervention programs aimed at reducing fat intake have had mixed results in this population. The transtheoretic model is proposed for achieving dietary change. Strategies for changing health behaviors in African-American women include heightening sensitivity to cultural values among health educators and the use of multiple strategies to reinforce messages. To stimulate healthier eating, it is important to incorporate the distinct habitual eating patterns into innovative intervention methods, using effective behavioral change methods.

Uterine myomas and factors associated with hysterectomy in premenopausal women

OBJECTIVE: Our purpose was to describe clinical characteristics in premenopausal women with uterine myomas and to identify factors associated with hysterectomy.STUDY DESIGN: Data were collected by chart abstraction in 421 premenopausal women with myomas and analyzed by univariate and multivariable regression.RESULTS: Over a median follow-up period of 29 months, 86% of women had symptoms associated with myomas and 40% had an increase in uterine size of >2 gestational weeks. By multivariable regression, bleeding symptoms at presentation and previous surgical history of cholecystectomy and adhesiolysis were significantly associated with greater odds of hysterectomy. There was a significant interaction between age and uterine size, so that as age increased, uterine size had a greater impact on the likelihood of hysterectomy.CONCLUSIONS: In this cohort of premenopausal women myomas were associated with symptoms in almost all women over the follow-up period. Hysterectomy was performed in 22% of women overall. (Am J Obstet Gynecol 1997;176:1213-9.)     

Mortality: What Are the Roles of Risk Factor Prevalence,Screening, and Use of Recommended Treatment?

CONTEXT: Despite advances in early detection and prevention of cervical cancer, women living in rural areas, and particularly in Appalachia, the rural South, the Texas/Mexico border, and the central valley of California, have had consistently higher rates of cervical cancer mortality than their counterparts in other areas during the past several decades. METHODS: This paper reviews the published literature from 1966 to July 2002 to assess three potential pathways underlying this excess mortality--high human papilloma virus (HPV) prevalence, lack of or infrequent screening and advanced disease at diagnosis, and under-use of recommended treatment and shorter survival. FINDINGS: Living in rural areas may impose barriers to cervical cancer control, including lack of transportation and medical care infrastructures. Population characteristics that place women at greater risk for developing and dying from cervical cancer, such as low income, lack of health insurance, and physician availability, are concentrated in rural areas. Published data, however, are insufficient to identify the key reasons for the observed mortality patterns. CONCLUSIONS: At this time, given the lack of definitive evidence in the published literature, decisions about priorities in areas with high rates of cervical cancer mortality will depend on knowledge of current levels of screening, incidence, and stage distribution; and service delivery infrastructures, resources, and acceptability of interventions to the target population.     

The Economic Value of Childhood Varicella Vaccination in France and Germany

OBJECTIVE: To determine the economic impact of childhood varicella vaccination in France and Germany. METHODS: A common methodology based on the use of a varicella transmission model was used for the two countries. Cost data (2002 per thousand) were derived from two previous studies. The analysis focused on a routine vaccination program for which three different coverage rates (CRs) were considered (90%, 70%, and 45%). Catch-up strategies were also analyzed. A societal perspective including both direct and indirect costs and a third-party payer perspective were considered (Social Security in France and Sickness Funds in Germany). RESULTS: A routine vaccination program has a clear positive impact on varicella-related morbidity in both countries. With a 90% CR, the number of varicella-related deaths was reduced by 87% in Germany and by 84% in France. In addition, with a CR of 90%, routine varicella vaccination induces savings in both countries from both societal (Germany 61%, France 60%) and third-party payer perspectives (Germany 51%, France 6.7%). For lower CRs, routine vaccination remains cost saving from a third-party payer perspective in Germany but not in France, where it is nevertheless cost-effective (cost per life-year gained of 6521 per thousand in the base case with a 45% CR). CONCLUSION: Considering the impact of vaccination on varicella morbidity and costs, a routine varicella vaccination program appears to be cost saving in Germany and France from both a societal and a third-party payer perspective. For France, routine varicella vaccination remains cost-effective in worst cases when a third-party payer perspective is adopted. Catch-up programs provide additional savings.     

Controversies in the management of children with bronchiolitis

In this review, we present and summarize data from recently conducted research regarding controversial aspects of the management of children with bronchiolitis. These data suggest that chronic medical history, gestational age at birth, postnatal age, and physiological variables can identify those children at higher risk for a more severe course of bronchiolitis. Large prospective studies also suggest that the likelihood of significant bacterial illness in febrile infants with bronchiolitis may be lower than in children without bronchiolitis. Nevertheless, urinary tract infections remain relatively common in young febrile children with bronchiolitis. Lastly and unfortunately, the data note a relative lack of effective therapies for children with bronchiolitis, although certain therapies such as systemic corticosteroids show potential efficacy and are in need of further study. The remaining uncertainty surrounding many issues pertaining to bronchiolitis highlight the need for more research aimed to: (1) develop prognostic models to identify patients at risk for a more severe clinical course, (2) develop generalizable diagnostic models to identify febrile infants with bronchiolitis at high and very low risk of significant bacterial illness, and (3) evaluate the effectiveness of promising therapies.     

Children of migratory agricultural workers: the ecological context of acute care for a mobile population of immigrant children

Migratory and seasonal agricultural workers fill the labor needs of United States farmers. Although migrant workers are a culturally and ethnically diverse population, presently, they are predominantly immigrants of Hispanic ethnicity. Migrant farm workers are increasingly young, financially impoverished, male, undocumented immigrants from Mexico. Families with children constitute 45% of this population. The ecological context of migrant children’s lives is characterized by poverty, social isolation, heightened inter- and intra-national mobility, limited protections from occupational safety and health legislation, and health access barriers. Moreover, the linkage of citizenship and immigration status to the receipt of public insurance and selected social services benefits has the potential to increase access barriers for migrant workers and their families. Despite these obvious vulnerabilities, few health services research studies address this population. Most of what is known relates to adults, with very little known about migrant children’s health services utilization patterns or health morbidities. In the emergency department setting, the differential approach required to care for children, as compared to adults, must be modified further in order to address the unique needs of this vulnerable population. The effective delivery of acute care to the children of migratory agricultural workers requires awareness of and attention to their unique health access barriers, issues of continuity and compliance with care, and their unique health and injury risks.     

Timely follow‐up of positive cancer screening results: A systematic review and recommendations from the PROSPR Consortium

Timely follow‐up for positive cancer screening results remains suboptimal, and the evidence base to inform decisions on optimizing the timeliness of diagnostic testing is unclear. This systematic review evaluated published studies regarding time to follow‐up after a positive screening for breast, cervical, colorectal, and lung cancers. The quality of available evidence was very low or low across cancers, with potential attenuated or reversed associations from confounding by indication in most studies. Overall, evidence suggested that the risk for poorer cancer outcomes rises with longer wait times that vary within and across cancer types, which supports performing diagnostic testing as soon as feasible after the positive result, but evidence for specific time targets is limited. Within these limitations, we provide our opinion on cancer‐specific recommendations for times to follow‐up and how existing guidelines relate to the current evidence. Thresholds set should consider patient worry, potential for loss to follow‐up with prolonged wait times, and available resources. Research is needed to better guide the timeliness of diagnostic follow‐up, including considerations for patient preferences and existing barriers, while addressing methodological weaknesses. Research is also needed to identify effective interventions for reducing wait times for diagnostic testing, particularly in underserved or low‐resource settings.
