RESUMO
Ice loss from the world's glaciers and ice sheets contributes to sea level rise, influences ocean circulation, and affects ecosystem productivity. Ongoing changes in glaciers and ice sheets are driven by submarine melting and iceberg calving from tidewater glacier margins. However, predictions of glacier change largely rest on unconstrained theory for submarine melting. Here, we use repeat multibeam sonar surveys to image a subsurface tidewater glacier face and document a time-variable, three-dimensional geometry linked to melting and calving patterns. Submarine melt rates are high across the entire ice face over both seasons surveyed and increase from spring to summer. The observed melt rates are up to two orders of magnitude greater than predicted by theory, challenging current simulations of ice loss from tidewater glaciers.
RESUMO
BACKGROUND: Smoking during pregnancy increases the health risks of the unborn child as well as the mother. Although smoking rates for the population as a whole have declined drastically in the past generation, since 1992 there has been an increase in smoking among women, teenagers, and adults living in poverty. The purpose of this study was to assess reading level, tobacco knowledge, attitudes, and practices of tobacco use among pregnant adult and adolescent women in the public health system in north Louisiana. METHODS: A convenience sample of 600 pregnant women was interviewed in person in the Obstetrics Clinics at Louisiana State University Health Sciences Center at Shreveport and E.A. Conway in Monroe. The structured interview contained detailed questions about smoking practices, tobacco knowledge, and attitudes. Reading was assessed using the Rapid Estimate of Adult Literacy in Medicine. Smoking practices were assessed by self-report and verified by measuring urine cotinine levels. The Cochran-Mantel-Haenszel test was used to estimate the relationship between reading level and knowledge and attitude; multiple logistic regression was used to determine which variable(s) predicted current smoking practices. RESULTS: Knowledge about the effects of smoking and concern about the health effect of smoking on their baby varied significantly by reading level, with participants with higher reading levels having more knowledge and greater concern. Smoking practices did not vary by reading level even when race, age, and living with a smoker were controlled. Race was a significant determinant of smoking practices, with more white women reporting currently smoking during pregnancy than African Americans (34% vs 8%). CONCLUSIONS: Reading level was related to knowledge about health effects of smoking. Women with higher reading levels were also more concerned about the adverse health effects of smoking on themselves and their babies. However, reading level was not correlated with smoking prevalence. The most significant determinant of smoking was race (with whites smoking significantly more than African Americans).

Phosphorus (P) is the key limiting nutrient in most UK freshwater systems. With increased legislation controlling point source inputs, dissolved (DP) and particulate P (PP) derived from diffuse sources are making a more significant contribution to the total P loading of surface waters. Recent research has focused on pathways linking diffuse sources to the fluvial system and sub-surface field drains have been shown to transport both sediment and P rapidly to watercourses. Preliminary results are presented from an ongoing study using environmental tracers to identify the source of the drain sediment and its potential as a carrier of PP. These results suggest that the majority of sediment in drains is topsoil derived, but the significance of P loss via this pathway in a regional or UK context has yet to be evaluated. A protocol to study the potential problem at a regional/national scale is discussed and initial data presented.

Phage display provides a methodology for obtaining fully human antibodies directed against human transforming growth factor-beta (TGFbeta) suitable for the treatment of fibrotic disorders. The strategy employed was to isolate a human single chain Fv (scFv) fragment that neutralises human TGFbeta2 from a phage display repertoire, convert it into a human IgG4 and then determine its TGFbeta binding and neutralisation properties and its physical characteristics. Several scFv fragments binding to TGFbeta2 were isolated by panning of an antibody phage display repertoire, and subsequent chain shuffling of the selected V(H) domains with a library of V(L) domains. The three most potent neutralising antibodies were chosen for conversion to IgG4 format. The IgG4 antibodies were ranked for their ability to neutralise TGFbeta2 and the most potent, 6B1 IgG4, was chosen for further characterisation. 6B1 IgG4 has a high affinity for TGFbeta2 with a dissociation constant of 0.89 nM as determined using the BIAcore biosensor and only 9% cross-reactivity with TGFbeta3 (dissociation constant, 10 nM). There was no detectable binding to TGFbeta1. 6B1 IgG4 strongly neutralises (IC50 = 2 nM) the anti-proliferative effect of TGFbeta2 in bioassays using TF1 human erythroleukaemia cells. Similarly, there was strong inhibition of binding of TGFbeta2 to cell surface receptors in a radioreceptor assay using A549 cells. 6B1 IgG4 shows no detectable cross-reactivity with related or unrelated antigens by immunocytochemistry or ELISA. The 6B1 V(L) domain has entirely germline framework regions and the V(H) domain has only three non-germline framework amino acids. This, together with its fully human nature, should minimise any potential immunogenicity of 6B1 IgG4 when used in therapy of fibrotic diseases mediated by TGFbeta2.

A series of carboxy-substituted cinnamides were investigated as antagonists of the human cell surface leukotriene B4 (LTB4) receptor. Binding was determined through measurement of [3H]LTB4 displacement from human neutrophils. Receptor antagonism was confirmed through a functional assay, which measures inhibition of Ca2+ release in human neutrophils. Potent antagonists were discovered through optimization of a random screening hit, a p-(alpha-methylbenzyloxy)cinnamide, having low-micromolar activity. Substantial improvement of in vitro potency was realized by the attachment of a carboxylic acid moiety to the cinnamide phenyl ring through a flexible tether, leading to identification of compounds with low-nanomolar potency. Modification of the benzyloxy substituent, either through ortho-substitution on the benzyloxy phenyl group or through replacement of the ether oxygen with a methylene or sulfur atom, produced achiral antagonists of equal or greater potency. The most potent compounds in vitro were assayed for oral activity using the arachidonic acid-induced mouse ear edema model of inflammation. Several compounds in this series were found to significantly inhibit edema formation and myeloperoxidase activity in this model up to 17 h after oral administration. Representatives of this series have been shown to be potent and long-acting orally active inhibitors of the LTB4 receptor.

OBJECTIVE: To study the effects of three approaches to increasing utilization of screening mammography in a public hospital setting in Northwest Louisiana. DESIGN: Randomized intervention study. POPULATION: Four hundred forty-five women aged 40 years and over, predominantly low-income and with low literacy skills, who had not had a mammogram in the preceding year. INTERVENTION: All interventions were chosen to motivate women to get a mammogram. Group 1 received a personal recommendation from one of the investigators. Group 2 received the recommendation plus an easy-to-read National Cancer Institute (NCI) brochure. Group 3 received the recommendation, the brochure, and a 12-minute interactive educational and motivational program, including a soap-opera-style video, developed in collaboration with women from the target population. MEASUREMENTS AND MAIN RESULTS: Mammography utilization was determined at 6 months and 2 years after intervention. A significant increase (p = .05) in mammography utilization was observed after the intervention designed in collaboration with patients (29%) as compared with recommendation alone (21%) or recommendation with brochure (18%) at 6 months. However, at 2 years the difference favoring the custom-made intervention was no longer significant. CONCLUSIONS: At 6 months there was at least a 30% increase in the mammography utilization rate in the group receiving the intervention designed in collaboration with patients as compared with those receiving the recommendation alone or recommendation with brochure. Giving patients an easy-to-read NCI brochure and a personal recommendation was no more effective than giving them a recommendation alone, suggesting that simply providing women in a public hospital with a low-literacy-level, culturally appropriate brochure is not sufficient to increase screening mammography rates. In a multivariate analysis, the only significant predictor of mammography use at 6 months was the custom-made intervention.

BACKGROUND: Low-income women utilize screening mammography less frequently, present at more advanced stages of disease, and have higher breast cancer mortality rates then women with higher incomes. The purpose of this study was to examine the relationship of reading ability to the knowledge and attitudes that low-income women have regarding screening mammography. METHODS: A convenience sample of 445 women were interviewed for this study. These women, age 40 years and older, had not had a mammogram in the past year. They were waiting to see a doctor in one of two outpatient clinics at Louisiana State University Medical Center in Shreveport when they were interviewed. A structured questionnaire assessed mammography knowledge and attitudes. Each patient's reading ability was assessed with the Rapid Estimate of Adult Literacy in Medicine (REALM). RESULTS: The women interviewed had a mean age of 56 years. Sixty-nine percent were African American, and 97% lived in households with annual incomes of less than $20,000. On the average, the highest grade completed in school was tenth grade. The average reading level was fourth to sixth grade, with 76% reading below a 9th-grade level. Lower reading ability correlated significantly with less mammography knowledge (P < 0.0001). A lack of accurate information about mammography was prevalent among low-level readers. Thirty-nine percent of women reading at or below a third-grade level did not know why women are given mammograms, compared with 12% of those reading at or above a ninth-grade level. Cost was a great concern in general, but cost concerns did not vary by reading level; 41% of all participants were very concerned about cost. CONCLUSIONS: Limited literacy skills and lack of knowledge about screening mammography may contribute considerably to the underutilization of screening mammograms in low-income women. Screening for reading level may identify a subset of low-income patients who could benefit from specialized education. These results could help guide effective educational interventions and better provider-patient communication about screening mammography for low-literate, low-income women.

The program described here tests the effectiveness of a community-based and school-based program to reduce violence among African-American and Hispanic adolescents. The program methods are based on social network theory research, which has found that key lay people in communities can be identified and trained to carry out prevention programs. The educational content is based on theories suggesting that characteristics of healthy, adaptive individuals and communities can be taught. A violence-prevention leadership program is provided to a cohort of middle-school student peer leaders and their parents and for the leaders of the neighborhoods around the middle schools. Three matched pairs of urban middle-school attendance zones were randomly assigned to receive either the intervention or serve as a nonintervention control group. Surveys, interviews, and observations were conducted with the peer leaders, their parents, community leaders, and community residents. Sixty-six percent of the peer leaders reported that they had hit someone in the past 30 days. Twenty-six percent of the sixth-graders had punched or beaten someone in the past 30 days. Within the past year, 6% of the adults had slapped or kicked someone. Within the past 30 days, 14% of the sixth-graders had been punched or beaten. Within the past year, 6% of the adults had been punched or beaten. A large percentage of adolescents are victims and perpetrators of violence and are exposed to violence in their neighborhoods. Violence-prevention strategies can be implemented through collaborations among health departments, community-based organizations, universities, and schools.

BACKGROUND: Medical information pamphlets often are written using language that requires a reading level higher than parents of many pediatric patients have achieved. Anecdotal reports suggest that many parents may not readily understand the federally mandated Public Health Service vaccine information pamphlets prepared by the Centers for Disease Control and Prevention (CDC) in 1991. The level at which the pamphlets need to be written for low-reading-level parents is undetermined, as is whether parents reading at higher levels will accept low-reading-level materials. METHODS: To determine whether a simple pamphlet prepared at a low reading level using qualitative and adult education techniques would be preferable to the available CDC polio vaccine information pamphlet, we conducted an integrated qualitative-quantitative study. We compared the parent reading time and comprehension of a simplified pamphlet (Louisiana State University, LSU) comprising 4 pages, 322 words, 7 instructional graphics, and a text requiring a 6th grade reading ability with the equivalent 1991 CDC vaccine information pamphlet comprising 16 pages, 18,177 words, no graphics, and a text requiring a 10th grade reading level. We measured the reading ability of 522 parents of pediatric patients from northwest Louisiana seen at public clinics (81%) and in a private office (19%). Of the entire group, 39% were white, 60% African-American, and 1% Hispanic; the mean age was 29 years; the mean highest grade completed was 12th grade 3 months; and the reading level was less than 9th grade in 47% of parents and less than 7th grade in 20%. After parents were given one of the pamphlets to read, their reading time, comprehension, and attitude toward the pamphlet were measured. RESULTS: Mean comprehension was 15% lower for CDC than for LSU (56% vs 72% correct; P < .001) and reading time was three times longer for CDC than for LSU (13 minutes 47 seconds vs 4 minutes 20 seconds; P < .0001). These trends were significant for parents reading at all but the lowest levels. Mean comprehension and reading time did not differ among parents reading at the third grade level or less. However, mean comprehension was greater and reading time lower for LSU among parents at all reading abilities greater than the third grade. Parents in the private practice setting took the longest time to read the CDC (20 minutes 59 seconds vs 5 minutes 46 seconds, LSU), yet their comprehension on the LSU was significantly higher than on the CDC (94% vs 71%; P < .0001). Two focus groups of high-income parents were unanimous in preferring the LSU. CONCLUSIONS: A short, simply written pamphlet with instructional graphics was preferred by high- and low-income parents seen in private and public clinics. The sixth grade reading level appears to be too high for many parents in public clinics; new materials aimed at third to fourth grade levels may be required. The new 1994 CDC immunization materials, written at the eighth grade level, may still be inappropriately high. The American medical community should adopt available techniques for the development of more effective patient-parent education materials.

"In the sixteenth and seventeenth centuries Spanish officials and members of the Catholic church created a series of race-based caste terms designed to identify and categorize the peoples of mixed ancestry. The Spanish American caste system relied on the assumed ability of a census-taker or priest to define the blood lines of an individual based on skin color and physical characteristics. However, the demographic knowledge created from the caste system was imprecise, and changed over time.... There were also long-term shifts in the meaning of terms and the definitions of status caused by socioeconomic changes. An example is the rapid rate of apparent mestizoization in the...indigenous communities of the Valle Bajo of Cochabamba, Bolivia. The rapid increase in the number of mestizos was related to changing definitions of the status and identity of indigenous peoples, and was not strictly caused by racial mixture."

Patients who misunderstand their diagnosis and treatment plans usually exhibit poor compliance. The 90 million adult Americans with low literacy skills struggle to understand such essential health information as discharge instructions, consent forms, oral instructions and drug labels. The Joint Commission on Accreditation of Health Organizations (JCAHO) now requires that instructions be given on a level understandable to the patient. Most physicians tend to give too much information on too high a level for many patients to understand. Physicians who speak in simpler language, repeat their instructions and demonstrate key points, while avoiding too many directives, enhance their patients' understanding. Combining easy-to-read written patient education materials with oral instructions has been shown to greatly enhance patient understanding. To be effective with patients whose literacy skills are low, patient education materials should be short and simple, contain culturally sensitive graphics and encourage desired behavior. Compliance with therapy also may be improved by including family members in the patient education process.

BACKGROUND AND OBJECTIVES: Because of its brevity and ease of use, the Mini-mental State Examination (MMSE) is commonly used to screen and follow patients with cognitive impairment. This pilot study attempted to determine the relationships between literacy, age, and self-reported educational level and the total MMSE score. METHODS: Cross-sectional analysis of all patients was followed by a family practice group at five local nursing homes. The associations between the patients' MMSE scores; literacy, as measured by the Rapid Estimate of Adult Literacy in Medicine (REALM); self-reported educational level; and age were determined using Pearson's correlation coefficient and stepwise multivariate linear regression. RESULTS: A total of 105 patients completed the study. Linear regression analysis showed that MMSE scores were significantly predicted by REALM score (P < .001) and the patient's age (P < .02). However, after accounting for REALM score and age, the self-reported educational level was not related to the MMSE score (P < .8). A significant relationship was seen between the REALM score and the subjects' self-reported educational levels (r = .44, P < .001) but not the subjects' ages (r = -.17, P < 0.09). A significant linear correlation was found between the MMSE and REALM scores (r = .71, P < .0001) and a significant inverse correlation was seen between MMSE scores and the patients' ages (r = -.28, P < .004). The correlation coefficient between the patients' MMSE scores and the self-reported educational levels was .33 (P < .0007). CONCLUSIONS: Practitioners who rely on the MMSE should be aware that patients may score in the demented range because they cannot read well enough to accurately complete the test. Literacy testing with REALM or other instruments may help identify such patients.

A new compound, bis(sulfato)-cyclosiphonodictyol A [1], which inhibits the binding of [3H]-LTB4 to intact human neutrophils with an IC50 value of 44 microM, was isolated from the sponge Siphonodictyon coralliphagum. The sponge was collected using the Johnson-Sea-Link manned submersible at a depth of 195 feet in the Bahamas. The compound was isolated via reversed-phase chromatography and its structure determined spectroscopically. To the best of our knowledge, 1 is the first marine-derived compound with two aromatic sulfate ester functionalities, and is also the first in the siphonodictyal series to contain an oxepane functionality.

To participate effectively in their health care, older patients often are expected to read a wide variety of materials, including written instructions, brochures, and consent forms. This study quantitates the reading ability of older patients and compares it to that of younger patients. Two hundred seventy-two patients 30 and older were selected from five outpatient clinics at a public teaching hospital and tested for objective reading ability using the Peabody Individual Achievement Test--Revised. The 76 patients 60 and older read significantly worse (grade level 2.9) than the 196 patients younger than 60 (grade level 5.8) (P < 0.0001). Older patients also completed significantly fewer years of school than younger patients (7.3 years versus 10.6 years). Analysis of variance for age categories 30-44, 45-59, 60-74, and 75 and older confirmed declining reading ability and educational status with advancing age. Multiple regression analysis helped show that an equation could be derived to predict reading ability from age, educational status, race, and sex, but the coefficient of determination was so low (r2 = 0.39) that it cannot be considered clinically useful for individual patients. In this study, older patients read significantly worse than younger patients, and a formula that combines age, race, sex, and educational status cannot reliably predict reading ability for individual patients. Most older patients read on a level so low that they cannot be expected to read most commonly used written materials. Routine testing of reading ability may allow more appropriate design and use of written materials.

OBJECTIVES: To test the reading ability of parents of pediatric outpatients and to compare their reading ability with the ability necessary to read commonly used educational materials; to compare individual reading grade levels with the levels of the last grade completed in school; and to further validate a new literacy screening test designed specifically for medical settings. DESIGN: Prospective survey. SETTING: Pediatrics outpatient clinic in a large, public university, teaching hospital. PARTICIPANTS: Three hundred ninety-six parents or other caretakers accompanying pediatric outpatients. MEASUREMENTS: Demographics and educational status were assessed using a structured interview. Reading ability was tested using the Rapid Estimate of Adult Literacy in Medicine (REALM) and the Wide Range Achievement Test-Revised. Written educational materials were assessed for readability levels with a computer program (Grammatik IV). RESULTS: The mean score on the REALM for all parents placed them in the seventh to eighth grade reading range, despite the mean self-reported last grade completed in school being 11th grade 5th month. Wide Range Achievement Test-Revised scores correlated well with REALM scores (0.82). Eighty percent of 129 written materials from the American Academy of Pediatrics, the Centers for Disease Control, the March of Dimes, pharmaceutical companies, and commercially available baby books required at least a 10th grade reading level. Only 25% of 60 American Academy of Pediatrics items and 19% of all materials tested were written at less than a ninth grade level, and only 2% of all materials were written at less than a seventh grade level. CONCLUSION: This study demonstrates that parents' self-reported education level will not accurately indicate their reading ability. Testing is needed to screen at-risk parents for low reading levels. In a public health setting, a significant amount of available parent education materials and instructions require a higher reading level than most parents have achieved. In such settings, all materials probably should be written at less than a high school level if most parents are to be expected to read them. The REALM can easily be used in busy public health clinics to screen parents for reading ability.

BACKGROUND: This study was conducted to validate a shortened version of the Rapid Estimate of Adult Literacy in Medicine (REALM). This screening instrument is designed to be used in public health and primary care settings to identify patients with low reading levels. It provides reading grade estimates for patients who read below a ninth-grade level. The REALM can be administered in one to two minutes by personnel with minimal training. METHODS: Two hundred and three patients in four university hospital clinics (internal medicine, family practice, ambulatory care, and obstetrics/gynecology) were given the REALM and three other standardized reading tests: the reading recognition section of the Peabody Individual Achievement Test-Revised (PIAT-R), the Wide Range Achievement Test-Revised (WRAT-R), and the Slosson Oral Reading Test-Revised (SORT-R). One hundred inmates at a state prison were also given the REALM twice, one week apart, to determine test-retest reliability. RESULTS: The REALM correlated well with the three other tests. (Correlation coefficients were 0.97 [PIAT-R], 0.96 [SORT-R], and 0.88 [WRAT-R].) All correlations were significant at P < .0001. Test-retest reliability was 0.99 (P < .001). CONCLUSIONS: The REALM provides an estimate of patient reading ability, displays excellent concurrent validity with standardized reading tests, and is a practical instrument for busy primary care settings.

Adult inpatients in state-supported (public) and private substance misuse treatment settings were tested for reading ability. Patient education materials and consent forms were assessed for readability levels. Public patients' mean reading levels were significantly lower than those of private patients, and were 4 to 5 years below the level needed to read and understand standard treatment materials. More than half of the public and almost one-third of the private patients tested were reading below a 9th grade level. Standard treatment materials were written on 11th to 12th grade reading levels; admission and consent forms were written on 12th to 18th grade levels. Patients in substance misuse settings should be tested for literacy levels upon admission and provided with materials commensurate with their reading ability.
