Abstract
BACKGROUND Understanding the clinical course and short-term outcomes of suspected myocarditis following COVID-19 vaccination has important public health implications in the decision to vaccinate youth. METHODS We retrospectively collected data on patients <21 years-old presenting before 7/4/2021 with suspected myocarditis within 30 days of COVID-19 vaccination. Lake Louise criteria were used for cardiac magnetic resonance imaging (cMRI) findings. Myocarditis cases were classified as confirmed or probable based on the Centers for Disease Control and Prevention definitions. RESULTS We report on 139 adolescents and young adults with 140 episodes of suspected myocarditis (49 confirmed, 91 probable) at 26 centers. Most patients were male (N=126, 90.6%) and White (N=92, 66.2%); 29 (20.9%) were Hispanic; and median age was 15.8 years (range 12.1-20.3, IQR 14.5-17.0). Suspected myocarditis occurred in 136 patients (97.8%) following mRNA vaccine, with 131 (94.2%) following the Pfizer-BioNTech vaccine; 128 (91.4%) occurred after the 2nd dose. Symptoms started a median of 2 days (range 0-22, IQR 1-3) after vaccination. The most common symptom was chest pain (99.3%). Patients were treated with nonsteroidal anti-inflammatory drugs (81.3%), intravenous immunoglobulin (21.6%), glucocorticoids (21.6%), colchicine (7.9%) or no anti-inflammatory therapies (8.6%). Twenty-six patients (18.7%) were in the ICU, two were treated with inotropic/vasoactive support, and none required ECMO or died. Median hospital stay was 2 days (range 0-10, IQR 2-3). All patients had elevated troponin I (N=111, 8.12 ng/mL, IQR 3.50-15.90) or T (N=28, 0.61 ng/mL, IQR 0.25-1.30); 69.8% had abnormal electrocardiograms and/or arrythmias (7 with non-sustained ventricular tachycardia); and 18.7% had left ventricular ejection fraction (LVEF) <55% on echocardiogram. Of 97 patients who underwent cMRI at median 5 days (range 0-88, IQR 3-17) from symptom onset, 75 (77.3%) had abnormal findings: 74 (76.3%) had late gadolinium enhancement, 54 (55.7%) had myocardial edema, and 49 (50.5%) met Lake Louise criteria. Among 26 patients with LVEF <55% on echocardiogram, all with follow-up had normalized function (N=25). CONCLUSIONS Most cases of suspected COVID-19 vaccine myocarditis occurring in persons <21 years have a mild clinical course with rapid resolution of symptoms. Abnormal findings on cMRI were frequent. Future studies should evaluate risk factors, mechanisms, and long-term outcomes.

Abstract
BACKGROUND Understanding the epidemiology and clinical course of multisystem inflammatory syndrome in children (MIS-C) and its temporal association with coronavirus disease 2019 (Covid-19) is important, given the clinical and public health implications of the syndrome. METHODS We conducted targeted surveillance for MIS-C from March 15 to May 20, 2020, in pediatric health centers across the United States. The case definition included six criteria: serious illness leading to hospitalization, an age of less than 21 years, fever that lasted for at least 24 hours, laboratory evidence of inflammation, multisystem organ involvement, and evidence of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) based on reverse-transcriptase polymerase chain reaction (RT-PCR), antibody testing, or exposure to persons with Covid-19 in the past month. Clinicians abstracted the data onto standardized forms. RESULTS We report on 186 patients with MIS-C in 26 states. The median age was 8.3 years, 115 patients (62%) were male, 135 (73%) had previously been healthy, 131 (70%) were positive for SARS-CoV-2 by RT-PCR or antibody testing, and 164 (88%) were hospitalized after April 16, 2020. Organ-system involvement included the gastrointestinal system in 171 patients (92%), cardiovascular in 149 (80%), hematologic in 142 (76%), mucocutaneous in 137 (74%), and respiratory in 131 (70%). The median duration of hospitalization was 7 days (interquartile range, 4 to 10); 148 patients (80%) received intensive care, 37 (20%) received mechanical ventilation, 90 (48%) received vasoactive support, and 4 (2%) died. Coronary-artery aneurysms (z scores ≥2.5) were documented in 15 patients (8%), and Kawasaki's disease-like features were documented in 74 (40%). Most patients (171 [92%]) had elevations in at least four biomarkers indicating inflammation. The use of immunomodulating therapies was common: intravenous immune globulin was used in 144 (77%), glucocorticoids in 91 (49%), and interleukin-6 or 1RA inhibitors in 38 (20%). CONCLUSIONS Multisystem inflammatory syndrome in children associated with SARS-CoV-2 led to serious and life-threatening illness in previously healthy children and adolescents.

Abstract
In support of a clinical trial in the pediatric population, available nonclinical and clinical data provide input on the study design and safety monitoring considerations. When the existing data are lacking to support the safety of the planned pediatric clinical trial, a juvenile animal toxicity study is likely required. Usually a single relevant species, preferably a rodent, is chosen as the species of choice, while a nonrodent species can be appropriate when scientifically justified. Juvenile toxicology studies, in general, are complicated both conceptually and logistically. Development in young animals is a continuous process with different organs maturing at different rates and time. Structural and functional maturational differences have been shown to affect drug safety. Key points to consider in conducting a juvenile toxicology study include a comparative development of the organ systems, differences in the pharmacokinetics/absorption, distribution, metabolism, excretion (PK/ADME) profiles of the drug between young animal and child, and logistical requirement in the juvenile study design. The purpose of this publication is to note pertinent points to consider when designing and conducting juvenile toxicology studies and to aid in future modifications and enhancements of these studies to enable a superior predictability of safety of medicines in the pediatric population.

Abstract
Nurses in primary health care (PHC) provide an increasing proportion of chronic disease management and preventive lifestyle advice. The databases MEDLINE, CINAHL, EMBASE and PsychINFO were searched and the articles were systematically reviewed for articles describing controlled adult lifestyle intervention studies delivered by a PHC nurse, in a PHC setting. Thirty-one articles describing 28 studies were analysed by comparison group which revealed: (i) no difference of effect when the same intervention was delivered by a PHC nurse compared to other health professionals in PHC (n = 2); (ii) the provision of counselling delivered by a PHC nurse was more effective than health screening (n = 10); (iii) counselling based on behaviour change theory was more effective than the same dose of non-behavioural counselling when at least three counselling sessions were delivered (n = 3). The evidence supports the effectiveness of lifestyle interventions delivered by nurses in PHC to affect positive changes on outcomes associated with the prevention of chronic disease including: weight, blood pressure, cholesterol, dietary and physical activity behaviours, patient satisfaction, readiness for change and quality of life. The strength of recommendations is limited by the small number of studies within each comparison group and the high risk of bias of the majority of studies.

Abstract
The issue of "equal health" for Aboriginal and Torres Strait Islander peoples involves a broad range of social determinants, in addition to physical health. The formation of an Australian college of Aboriginal and Torres Strait Islander health would allow a continuing authoritative conference of broad expert opinion, including that of Aboriginal health workers, to address health and social inequality.

Abstract
This study addresses the viability of sol-gel encapsulated HRP (HRP:sol-gel) as a recyclable solid-state catalytic material. Ferric, ferric-CN, ferrous, and ferrous-CO forms of HRP:sol-gel were investigated by resonance Raman and UV-visible methods. Electronic and vibrational spectroscopic changes associated with changes in spin state, oxidation state, and ligation of the heme in HRP:sol-gel were shown to correlate with those of HRP in solution, showing that the heme remains a viable ligand-binding complex. Furthermore, the high-valent HRP:sol-gel intermediates, compound I and compound II, were generated and identified by time-resolved UV-visible spectroscopy. Catalytic activity of the HRP:sol-gel material was demonstrated by enzymatic assays by using I(-), guaiacol, and ABTS as substrates. Encapsulated HRP was shown to be homogeneously distributed throughout the sol-gel host. Differences in turnover rates between guaiacol and I(-) implicate mass transport of substrate through the silicate matrix as a defining parameter in the peroxidase activity of HRP:sol-gel. HRP:sol-gel was reused as a peroxidation catalyst for multiple reaction cycles without loss of activity, indicating that such materials show promise as reusable catalytic materials.

Abstract
The objectives of the study were to determine the relationship between functional health literacy and performance on the Mini-Mental State Examination (MMSE). New Medicare managed-care enrollees aged 65 years and older, living independently in the community in four US cities (Cleveland, Houston, Tampa, and Fort Lauderdale/Miami), were eligible to participate. In-home interviews were conducted to determine demographics and health status, and interviewers then administered the Short Test of Functional Health Literacy in Adults (S-TOFHLA) and the MMSE. We then determined the relationship between functional health literacy and the MMSE, including total scores, subscale scores (orientation to time, orientation to place, registration, attention and calculation, recall, language, and visual construction), and individual items. Functional health literacy was linearly related to the total MMSE score across the entire range of S-TOFHLA scores (R(2) = 0.39, p < 0.001). This relationship between health literacy and MMSE was consistent across all MMSE subscales and individual items. Adjustment for chronic conditions and self-reported overall health did not change the relationship between health literacy and MMSE score. Health literacy was related to MMSE performance even for subscales of the MMSE that were not postulated to be directly dependent on reading ability or education (e.g. delayed recall). These results suggest that the lower MMSE scores for patients with low health literacy are only partly due to 'test bias' and also result from true differences in cognitive functioning. 'Adjusting' MMSE scores for an individual's functional health literacy may be inappropriate because it may mask true differences in cognitive functioning.

Abstract
A microprocessor-controlled tubular multiple metered dose inhaler (MDI) aerosol generator was constructed for the delivery of pharmaceutical aerosols to inhalation chambers. The MDIs were mounted in four cassettes containing one to four MDIs on a stepped end plate. The MDIs in each cassette were pneumatically activated at intervals that were controlled by the microprocessor. The cassettes permitted easy replacement of each set of MDIs with a fresh set of MDIs whenever necessary. Aerosol concentration was controlled by varying the number of active MDIs in each cassette and the frequency of activations per minute of each row. Aerosol from the MDIs flowed along the long axis of the tube, which provided a path length sufficient to diminish impaction losses. Using a light-scattering device to monitor the aerosol concentration, the pulsatile output from the MDIs in the cassettes was demonstrated to be adequately damped out provided that the dilution/mixing/aging chamber exceeded 3 ft in length. The tube diameter selected was the minimum compatible with mounting the required number of MDIs so that the linear velocity of the aerosol was adequate to efficiently transport the aerosol out of the dilution chamber. Aerosol concentration and particle size data were recorded for a nose-only rodent exposure chamber. Reproducible aerosol concentrations ranging from 0.03 to 0.6 mg/L were generated. Particle sizes ranged from 2- to 3-microm mass median aerodynamic diameter. Thus, the aerosol generated was within the size range suitable for inhalation exposures.

Abstract
A novel gene product, GPR74, with homology to the seven transmembrane-domain receptor superfamily, has been cloned. GPR74 has been identified from the expressed sequence tags (EST) database. Subsequent PCR amplification of that sequence and screening of a human heart cDNA library led to the isolation of a 1.7-kb cDNA clone encoding a protein of 408 amino acids. GPR74 shows highest amino acid identity (33%) to the human neuropeptide Y-receptor subtype Y2. The human and mouse genes for GPR74 have been isolated and their exon-intron structures determined. In both species the gene consists of four exons spanning around 20 kb with the exon-intron borders being 100% conserved. Northern analysis of various human tissues reveals highest levels of mRNA expression in brain and heart. In situ hybridisation analysis of rat brain tissue confirms this result and identifies the hippocampus and amygdala nuclei as the brain areas with particular high expression of GPR74 mRNA. Fluorescence in situ hybridisation, PCR analysis on a radiation hybrid panel and interspecific mouse backcross mapping have localised the genes to human chromosome 4q21 and mouse chromosome 5. Expression of the human GPR74 cDNA as a GFP-fusion protein in various cell lines reveals the inability of the recombinant receptor protein to reach the cell surface. This is consistent with the lack of NPY specific binding in these cells and suggests that unknown factors are required for a full functional receptor complex.

Abstract
Several gene duplication events have led to the creation of at least five distinct members of the neuropeptide Y gene family. We now reveal that the most recent of these events, involving the PYY-PPY gene cluster on chromosome 17q21.1, has led to the creation of novel PYY- and PP-like genes on chromosome 17q11 in the human genome. Sequence analysis of the novel human PYY2 and PPY2 genes shows an extensive homology to the peptide YY-pancreatic polypeptide genes, at the level of gene structure, nucleotide sequence, and primary amino acid sequence. The extremely high degree of homology between the PYY-PPY and the PYY2-PPY2 gene clusters, in both coding regions and especially noncoding regions, suggests that the PYY2 and PPY2 genes have arisen by a very recent gene duplication. Similar gene duplication events of the PYY-PPY gene cluster have also occurred in other species, including cow and baboon, but have not been confirmed in the rat and mouse genomes. Interestingly, despite the greater than 92% nucleotide sequence identity between these new genes, a few specific mutations have resulted in significantly altered peptide sequences. These altered sequences are accompanied by acquisition of new functions apparently unrelated to the neurotransmitter/endocrine role of PYY and PPY, as demonstrated by the major involvement of bovine PYY2, also known as seminal plasmin, in the fertilization process.

Abstract
Reductions in testicular mass, sperm motility, and mating frequency have been attributed to the stresses caused by confinement of Sprague-Dawley male rats in nose-only inhalation exposure tubes. Testicular changes, including an increase in testicular atrophy, have been detected at an increased incidence in male rats used in inhalation studies as compared with rats of the same age and strain used in oral toxicity studies. This study was designed to determine whether nose-only exposure of male rats caused testicular toxicity under conditions of cooling of the exposure room and appropriate acclimation to the exposure tubes. In order to acclimate the rats to the nose-only inhalation exposure apparatus, all male rats were placed in the exposure tubes for at least four successively increasing time intervals (15, 30, 45, and 60 min) on 4 separate days, with a rest period of approximately 48 h between the first and second acclimation. Twenty male rats were exposed nose-only to filtered air for approximately 2 h per day for 28 days before cohabitation and continuing throughout a 14-day cohabitation period. To reduce thermal stress, the exposure room temperature was maintained at 64 to 70 degrees F. Twenty control rats were housed in the same room as the exposed rats but were not placed in exposure tubes. End points monitored were body weight, testicular weight, sperm count, sperm motility, and histopathology of the testes, epididymides, prostate, and seminal vesicles. The control rats gained weight more rapidly than the exposed rats. All the rats in both groups mated successfully, and testicular weights, normalized to body weight, were similar for both groups. More importantly, there were no microscopic changes that could be considered an adverse effect on the reproductive tissues in the male rats placed in exposure tubes. Thus, nose-only exposure for up to 2 h per day for a total of 42 days did not cause adverse effects on the reproductive organs, fertility, or reproductive performance of male rats under the conditions of this study.

Abstract
Four fragrances, 6-acetyl-1,1,2,4,4,7-hexamethyltetraline (AHTN), 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta-gamma-2-ben zopyran (HHCB), musk ketone and musk xylene were tested for developmental toxicity in Sprague-Dawley rats (25/group, 3 groups/fragrance, 2 fragrances/corn oil control). Dosages tested were HHCB: 50, 150, 500 mg/kg per day; AHTN: 5, 15, 50 mg/kg per day; musk ketone: 15, 45, 150 mg/kg per day; musk xylene: 20, 60, 200 mg/kg per day. All dosages tested exceeded multiples of the estimated maximal daily human dermal exposure. Treatment (gavage, 5 ml/kg) occurred on GDs 7-17 and Caesarean-sectioning on GD 20. Based on the results of these studies, none of the four fragrances tested were more toxic in the conceptuses than in the dams. Maternal NOAELs were 50, 5, 15 and 20 mg/kg per day for HHCB, AHTN, musk ketone and musk xylene, respectively (150, 50, 45 and 60 mg/kg per day caused clinical signs and reduced weight gain and feed consumption). Developmental NOAELs were 150, 50, 45 and 200 mg/kg per day for HHCB, AHTN, musk ketone and musk xylene, respectively. No adverse effects on embryo-fetal viability, growth or morphology occurred at the highest dosages of AHTN (50 mg/kg per day) or musk xylene (200 mg/kg per day). Developmental toxicity occurred at the high-dosages of HHCB (axial skeletal malformations at 500 mg/kg per day) and musk ketone (increased postimplantation loss and reduced fetal body weight at 150 mg/kg per day). The results of this study indicate that under conditions of normal use, the tested fragrances do not pose a risk to human conceptuses.

Abstract
We describe the development of an abbreviated version of the Test of Functional Health Literacy in Adults (TOFHLA) to measure patients' ability to read and understand health-related materials. The TOFHLA was reduced from 17 Numeracy items and 3 prose passages to 4 Numeracy items and 2 prose passages (S-TOFHLA). The maximum time for administration was reduced from 22 minutes to 12. In a group of 211 patients given the S-TOFHLA, Cronbach's alpha was 0.68 for the 4 Numeracy items and 0.97 for the 36 items in the 2 prose passages. The correlation (Spearman) between the S-TOFHLA and the Rapid Estimate of Adult Literacy in Medicine (REALM) was 0.80, although there were important disagreements between the two tests. The S-TOFHLA is a practical measure of functional health literacy with good reliability and validity that can be used by health educators to identify individuals who require special assistance to achieve learning goals.

Abstract
Molecular cloning techniques have recently led to the identification of a growing number of neuropeptide Y-receptor subtypes, suggesting possible subtype-specific involvement in different physiological processes. Here we report the first study which determines and compares the mRNA expression of all four cloned functional Y-receptor subtypes (Y1, Y2, Y4 and Y5) in consecutive sections of the rat brain on a cellular level, using a uniform in situ hybridization technique. Our results demonstrate that Y-receptor subtype mRNA expression is widely distributed throughout the rat brain. Interestingly, coexpression of all four Y-receptors, at different levels, is particularly evident within the limbic system, including the hypothalamus, hippocampus, amygdala, piriform and cingulate cortices and tegmental areas, all of which are heavily involved in behaviour, emotion and homeostatic regulation. Particularly interesting is the demonstration that Y5-receptor mRNA expression always coincides with the presence of Y1-receptor mRNA (although not vice versa), possibly due to the overlapping organization and transcriptional control of their genes. However, it is also clear that several brain nuclei display preferential expression of one or a selective combination of Y-receptor subtype mRNAs. Furthermore, it is evident that there is regionalization of expression within certain loci which express all four receptor subtype mRNAs, particularly within the paraventricular and arcuate hypothalamic nuclei. Our results suggest that some of neuropeptide Y's (NPY) effects may be mediated through one particular subtype, whereas other physiological processes might require the coordinated action of different subtypes within the same or discrete areas.

Abstract
CONTEXT Elderly patients may have limited ability to read and comprehend medical information pertinent to their health. OBJECTIVE To determine the prevalence of low functional health literacy among community-dwelling Medicare enrollees in a national managed care organization. DESIGN Cross-sectional survey. SETTING Four Prudential HealthCare plans (Cleveland, Ohio; Houston, Tex; south Florida; Tampa, Fla). PARTICIPANTS A total of 3260 new Medicare enrollees aged 65 years or older were interviewed in person between June and December 1997 (853 in Cleveland, 498 in Houston, 975 in south Florida, 934 in Tampa); 2956 spoke English and 304 spoke Spanish as their native language. MAIN OUTCOME MEASURE; Functional health literacy as measured by the Short Test of Functional Health Literacy in Adults. RESULTS Overall, 33.9% of English-speaking and 53.9% of Spanish-speaking respondents had inadequate or marginal health literacy. The prevalence of inadequate or marginal functional health literacy among English speakers ranged from 26.8% to 44.0%. In multivariate analysis, study location, race/language, age, years of school completed, occupation, and cognitive impairment were significantly associated with inadequate or marginal literacy. Reading ability declined dramatically with age, even after adjusting for years of school completed and cognitive impairment. The adjusted odds ratio for having inadequate or marginal health literacy was 8.62 (95% confidence interval, 5.55-13.38) for enrollees aged 85 years or older compared with individuals aged 65 to 69 years. CONCLUSIONS Elderly managed care enrollees may not have the literacy skills necessary to function adequately in the health care environment. Low health literacy may impair elderly patients' understanding of health messages and limit their ability to care for their medical problems.

Abstract
OBJECTIVES This study examined risk factors for not having a regular source of care among children presenting to an urban public hospital for nonappointment care. Lack of a regular source of care is associated with decreased use of appropriate health care services and preventive care among children. METHODS A cross-sectional survey was conducted for all children less than 16 years of age attending an emergency department at an urban public hospital over a consecutive 7-day period. Univariate and multivariate logistic regression analyses were conducted. RESULTS In 791 interviews available for analysis, 52% of preschool children and 66% of school-aged children did not have a regular source of care. Children without a regular source of care were more likely to present for nonurgent conditions (P < 0.0005). In multivariate analysis, older age of the child (OR = 1.6, 95% CI 1.132.25), lack of insurance (OR = 1.47, 95% CI 1.03-2.11), and lack of personal vehicle (OR = 1.44, 95% CI 1.05-1.97) were associated with not having a regular source of care. CONCLUSIONS The majority of children using an urban emergency department were without a regular source of care. In this population, no single factor identified children without a regular source of care, but increased age and lack of insurance were associated with it. Addressing this situation will require a multifaceted approach that includes, but is not limited to, decreasing financial barriers.

Abstract
A novel gene product, GPR56, with homology to the seven transmembrane-domain receptor superfamily, has been cloned by PCR amplification using degenerate oligonucleotide primers and subsequent screening of a human heart cDNA library. The isolated 2.8-kb cDNA clone encodes a protein of 693 amino acids that shows highest identity (32%) to HE6, a member of a subclass of the class B secretin-like G-protein-coupled receptors. Northern analysis of various human tissues revealed a wide distribution of the transcript with highest levels found in thyroid gland, brain, and heart. In situ hybridization analysis of human thyroid gland as well as rat heart and brain tissue confirms these results and identifies the hippocampus and hypothalamic nuclei as brain areas with particularly high expression of GPR56 mRNA. The high level of mRNA expression, its wide distribution, and the mucin-like extracellular domain of the receptor protein suggest a possible role for this receptor in cell-cell interaction processes. The human gene for GPR56 has been isolated and its exon-intron structure determined. The total length of the human GPR56 gene is approximately 15 kb, and it consists of 13 exons. Fluorescence in situ hybridization, PCR analysis of somatic cell hybrids, and interspecific mouse backcross mapping have localized the genes to human chromosome 16q13 and mouse chromosome 8.

Abstract
OBJECTIVE To examine the relationship between reading ability and family planning knowledge and practices among Medicaid managed care enrollees. METHODS A total of 406 women age 19-45 years enrolled in TennCare and members of Prudential HealthCare Community Plan in Memphis, Tennessee were interviewed to determine their methods of contraception, desire for additional information about contraceptives, and knowledge about the time in menstrual cycle they are at highest risk for pregnancy. Patient reading ability was assessed by an abbreviated version of the Test of Functional Health Literacy of Adults. The independent associations between reading ability, desire for additional contraceptive information, and knowledge about the highest risk time for pregnancy were assessed with logistic regression. RESULTS Almost 10% of the respondents had low reading skills. Women who had used an intrauterine device, douching, rhythm, or levonorgestrel implants as methods of birth control had higher rates of low reading skills than women who used other methods of birth control. Compared with women with good reading skills, women with low reading skills were 2.2 times (95% confidence interval [CI] 1.1, 4.4) more likely to want to know more about birth control methods and 4.4 times (95% CI 2.2, 9.0) more likely to have incorrect knowledge about when they were most likely to get pregnant. These relationships were significant even after controlling for age, race, and marital status. CONCLUSION Health providers and organizations that serve historically underserved populations must understand that some individuals have a low level of reading ability that limits family planning education.

Abstract
OBJECTIVE To determine the association between patient literacy and hospitalization. DESIGN Prospective cohort study. SETTING Urban public hospital. PATIENTS A total of 979 emergency department patients who participated in the Literacy in Health Care study and had completed an intake interview and literacy testing with the Test of Functional Health Literacy in Adults were eligible for this study. Of these, 958 (97.8%) had an electronic medical record available for 1994 and 1995. MEASUREMENTS AND MAIN RESULTS Hospital admissions to Grady Memorial Hospital during 1994 and 1995 were determined by the hospital information system. We used multivariate logistic regression to determine the independent association between inadequate functional health literacy and hospital admission. Patients with inadequate literacy were twice as likely as patients with adequate literacy to be hospitalized during 1994 and 1995 (31. 5% vs 14.9%, p <.001). After adjusting for age, gender, race, self-reported health, socioeconomic status, and health insurance, patients with inadequate literacy were more likely to be hospitalized than patients with adequate literacy (adjusted odds ratio [OR] 1.69; 95% confidence interval [CI] 1.13, 2.53). The association between inadequate literacy and hospital admission was strongest among patients who had been hospitalized in the year before study entry (OR 3.15; 95% CI 1.45, 6.85). CONCLUSIONS In this study population, patients with inadequate functional health literacy had an increased risk of hospital admission.

Abstract
The mRNA expression patterns for the Y1, Y2, Y4 and Y5 receptor subtypes have been compared at a cellular level within consecutive coronal sections of rat hippocampus, using a uniform method of in situ hybridisation. All four receptor subtypes show different levels and patterns of expression. The Y5 receptor mRNA is most abundant and most widely distributed (CA3 > DG approximately = CA2 approximately = CA1). Numerous Y5 mRNA-expressing neurons are also observed in the dentate gyrus polymorphic layer, while several positively-labelled neurons are detected in the molecular layer and in the stratum oriens. The Y2 receptor displays lower hybridisation signal relative to the Y5, although the expression pattern is similar. Moderate levels of Y1 mRNA expression are detected in the pyramidal cell layer of CA3-CA1 fields. However, only 20% of dentate gyrus granule neurons express Y1 receptor mRNA. In contrast, Y4 receptor mRNA is much less abundant, only small subpopulations of Y4 receptor expressing neurons are detected within the dentate gyrus and the CA3 to CA1 fields. This differential Y-receptor subtype expression pattern indicates specific and separate roles for these receptors in hippocampus processing, which may prove important in dysfunctional states, such as epilepsy and Alzheimer's disease.

Abstract
OBJECTIVE To describe primary care clinic use and emergency department (ED) use for a cohort of public hospital patients seen in the ED, identify predictors of frequent ED use, and ascertain the clinical diagnoses of those with high rates of ED use. DESIGN Cohort observational study. SETTING A public hospital in Atlanta, Georgia. PATIENTS Random sample of 351 adults initially surveyed in the ED in May 1992 and followed for 2 years. MEASUREMENTS AND MAIN RESULTS Of the 351 patients from the initial survey, 319 (91%) had at least one ambulatory visit in the public hospital system during the following 2 years and one third of the cohort was hospitalized. The median number of subsequent ED visits was 2 (mean 6.4), while the median number of visits to a primary care appointment clinic was O (mean 1.1) with only 90 (26%) of the patients having any primary care clinic visits. The 58 patients (16.6%) who had more than 10 subsequent ED visits accounted for 65.6% of all subsequent ED visits. Overall, patients received 55% of their subsequent ambulatory care in the ED, with only 7.5% in a primary care clinic. In multivariate regression, only access to a telephone (odds ratio [OR] 0.48; 95% confidence interval [CI] 0.39, 0.60), hospital admission (OR 5.90; 95% CI 4.01, 8.76), and primary care visits (OR 1.68; 95% CI 1.34, 2.12) were associated with higher ED visit rates. Regular source of care, insurance coverage, and health status were not associated with ED use. From clinical record review, 74.1% of those with high rates of use had multiple chronic medical conditions, or a chronic medical condition complicated by a psychiatric diagnosis, or substance abuse. CONCLUSIONS All subgroups of patients in this study relied heavily on the ED for ambulatory care, and high ED use was positively correlated with appointment clinic visits and inpatient hospitalization rates, suggesting that high resource utilization was related to a higher burden of illness among those patients. The prevalence of chronic medical conditions and substance abuse among these most frequent emergency department users points to a need for comprehensive primary care. Multidisciplinary case management strategies to identify frequent ED users and facilitate their use of alternative care sites will be particularly important as managed care strategies are applied to indigent populations who have traditionally received care in public hospital EDs.

Abstract
Many pharmaceuticals are administered to children and adults as sprays provided in nebulizers or metered-dose inhalers. Stress associated with possible eye irritation and injury attributable to exposure to vapors and particulates during the required safety testing procedures of such medicines is a potential confounding factor in these studies. Reducing stress and the potential changes associated with stress is particularly important in safety studies involving pregnant animals because maternal stress has been known to be associated with adverse outcomes for the offspring. Training and acclimating rabbits to wearing modified pediatric swim goggles during exposure to vapors and aerosol particles provides a simple, inexpensive method to reduce or eliminate potential stress from eye irritation.

Abstract
BACKGROUND Inadequate functional health literacy is common, but its impact on patients with chronic diseases is not well described. OBJECTIVE To examine among patients with hypertension or diabetes the relationship between their functional health literacy level and their knowledge of their chronic disease and treatment. METHODS We conducted a cross-sectional survey of patients with hypertension and diabetes presenting to the general medicine clinics at 2 urban public hospitals. Literacy was measured by the Test of Functional Health Literacy in Adults. Knowledge of their illness was assessed in patients with diabetes or hypertension using 21 hypertension and 10 diabetes questions based on key elements in educational materials used in our clinics. RESULTS A total of 402 patients with hypertension and 114 patients with diabetes were enrolled. Mean (+/- SD) knowledge scores for patients with hypertension with inadequate (n = 189), marginal (n = 49), or adequate (n = 155) literacy were 13.2 +/- 3.1, 15.3 +/- 2.2, and 16.5 +/- 2.3, respectively (range, 4-20; P < .001). A total of 92% of patients with hypertension and adequate literacy levels knew that a blood pressure reading of 160/100 mm Hg was high compared with 55% of those in the lowest reading level (P < .001). Mean (+/- SD) knowledge scores for patients with diabetes with inadequate (n = 50), marginal (n = 13), or adequate (n = 51) literacy were 5.8 +/- 2.1, 6.8 +/- 1.9, and 8.1 +/- 1.6, respectively (range, 1-10; P < .001). A total of 94% of patients with diabetes and adequate functional health literacy knew the symptoms of hypoglycemia compared with 50% of those with inadequate literacy (P < .001). CONCLUSIONS Inadequate functional health literacy poses a major barrier to educating patients with chronic diseases, and current efforts to overcome this appear unsuccessful.

Abstract
OBJECTIVES This study examined the relationship of functional health literacy to self-reported health and use of health services. METHODS Patients presenting to two large, urban public hospitals in Atlanta, Ga, and Torrance, Calif, were administered a health literacy test about their overall health and use of health care services during the 3 months preceding their visit. RESULTS Patients with inadequate functional health literacy were more likely than patients with adequate literacy to report their health as poor. Number of years of school completed was less strongly associated with self-reported health. Literacy was not related to regular source of care or physician visits, but patients in Atlanta with inadequate literacy were more likely than patients with adequate literacy to report a hospitalization in the previous year. CONCLUSIONS Low literacy is strongly associated with self-reported poor health and is more closely associated with self-reported health than number of years of school completed.

Abstract
Autoradiographic binding studies using the 5-HT3 (5-hydroxytryptamine3) receptor radioligand, [3H]-(S)-zacopride (0.5 nM), identified a heterogeneous distribution of specific binding sites (defined by granisetron, 1 microM) throughout the human brain. Highest radiolabelled 5-HT3 receptor densities were detected in discrete nuclei within the brainstem (nucleus tractus solitarius, area postrema, spinal trigeminal nerve nucleus; 50-200 fmol/mg tissue equivalent) with more modest levels of expression in the forebrain (e.g. hippocampus, nucleus accumbens, putamen, caudate; 4-17 fmol/mg tissue equivalent). Within the hippocampal formation, radiolabelled 5-HT3 receptors were differentially distributed with highest levels in the granule cell layer of the dentate gyrus. Saturation studies with [3H]-(S)-zacopride (0.05-16 nM; non-specific binding defined by granisetron, 10 microM) binding to homogenates of human putamen indicated that [3H]-(S)-zacopride (0.05-16 nM; non-specific binding defined by granisetron, 10 microM) binding to homogenates of human putamen indicated that [3H]-(S)-zacopride labelled an apparently homogenous population of binding sites (Bmax = 72 + 7 fmol mg-1 protein, pKd = 8.69 +/- 0.09, Hill coefficient = 0.99 +/- 0.06, mean +/- SEM, n = 4). The pharmacological profile of [3H]-(S)-zacopride binding to homogenates of putamen indicated the selective labelling of the human variant of the 5-HT3 receptor. The marked differences, however, in the pharmacology (e.g. low affinity for D-tubocurarine) and relative distribution (e.g. presence of 5-HT3 receptors in the human extrapyramidal system) of 5-HT3 receptors in the human forebrain when compared with other species further necessitates caution in predicting clinical responses based on data generated in animal models of disease.

Abstract
BACKGROUND Despite established evidence that screening for breast and cervical cancer reduces mortality in women, screening is underutilized, especially in poor, minority women. We hypothesized that a high percentage of women presenting for care to an inner-city medical walk-in clinic would report inadequate screening for breast and cervical cancer by current standards, accept same-day screening, and comply with recommended follow-up. METHODS To determine how many women presenting to our medical Walk-In Clinic were inadequately screened for breast and cervical cancer and how many were willing to undergo same-day screening, we surveyed all women at this site over a three month period. We then implemented a one-year, same-day screening program and contacted patients with abnormal screening results by letter or phone to encourage follow up. We tracked patients to assess compliance with follow-up. RESULTS Of the 2,363 women in the initial survey, 1,230 (52%) reported inadequate screening, of whom 55% reported interest in same-day screening. Over the one year screening period, we screened 403 women for breast and/or cervical cancer. Of the 48 women with abnormal Pap tests, compliance with initial Gynecology Clinic follow-up was 56%. Compliance was 49% with mammography appointments, and 77% for follow-up to Breast Clinic for clinical and/or mammographic abnormalities. These compliance rates compare favorably to those for screening performed in more traditional settings. CONCLUSION Our results support the establishment of cancer screening programs in nontraditional settings such as walk-in clinics and emergency departments to target patients who are at high risk for remaining unscreened.

Abstract
OBJECTIVE To describe what is known about the relation of literacy skills to contraceptive use and to suggest directions for future research. An overview of what is known about the literacy skills of Americans and the prevalence of inadequate functional health literacy is presented. Information about reading requirements for various methods of contraception and advice from health educators on dealing with low-literate populations are described. DATA SOURCES MEDLINE, PsychInfo, and ERIC searches for the last 20 years were completed using the terms literacy, literacy and health, family planning, health status, educational status, risk factors, contraception, and pregnancy. METHODS OF STUDY SELECTION The primary literature searches identified 125 articles. After reviewing abstracts for these articles, we excluded 79, because they contained no specific mention of literacy or educational status relating to contraception. TABULATION INTEGRATION, AND RESULTS: We were unable to identify and study specifically devoted to the relation between functional literacy and actual use of contraceptives. Forty-six with relevant background or related information were identified: literacy and health (19), adult literacy (nine), literacy and contraception (11), and literacy and family planning (seven). Over one-third of English-speaking and 62% of Spanish-speaking patients had inadequate or marginal functional health literacy in a study conducted at two urban public hospitals. Studies by health educators have demonstrated that information for many types of contraceptives is frequently above the patient's reading level. Available epidemiologic information on the relation between educational status and unplanned pregnancy is also presented. CONCLUSIONS Although no study has specifically addressed how functional health literacy affects contraceptive use, it is reasonable to hypothesize that functional health literacy influences contraceptive knowledge, attitudes, and behaviors. Future research should focus on the relation between functional health literacy and actual use of various contraceptives.

Abstract
OBJECTIVES To understand the difficulties that patients with poor reading ability have interacting with the health care system and to identify the coping mechanisms they use to deal with these problems. DESIGN Focus groups and individual interviews with patients who are illiterate and patients with low literacy. SETTING Two large, urban public hospitals. PARTICIPANTS Sixty patients with marginal to poor reading abilities as measured by the Rapid Estimate of Adult Literacy in Medicine were interviewed in focus groups or individual interviews. MEASUREMENTS AND MAIN RESULTS Patients with low literacy harbor a deep sense of shame, which is reinforced by hospital staff who become frustrated or angry when someone cannot complete a form or read instructions. Seeking medical care is intimidating for patients with low literacy because they cannot understand signs and registration forms. Many patients recounted serious medication errors resulting from their inability to read labels. To cope with these problems, the patients with low literacy rely heavily on oral explanations, visual clues, and demonstrations of tasks to learn new material. Most also use a friend or family member as a surrogate reader. CONCLUSIONS Patients with poor reading ability have important problems accessing the health care system, understanding recommended treatments, and following the instructions of providers. Because of their shame, patients with low literacy may be unwilling to disclose their problem to health care providers, and screening tests of reading ability may be necessary to identify those who need special assistance. Patients' coping mechanisms give insight into possible interventions that may improve their interactions with the health care system.

Abstract
Illiteracy is a well known national crisis, yet relatively little research has focused on how low literacy affects patients' health care experiences. The purpose of this study was to determine the relationship between shame and low functional literacy in the health care setting. It hypothesized that many patients with low literacy may not admit they have difficulty reading because of shame. Patients who presented for acute care at a large, public hospital in Atlanta, Georgia were interviewed. A total of 202 predominately indigent African-American patients completed a demographic survey, the Test of Functional Health Literacy in Adults (TOFHLA) and answered questions about difficulty reading and shame. Of the 202 patients interviewed, 42.6% had inadequate or marginal functional health literacy. Patients with low literacy were more likely to be male (P < 0.05), have less than a high school education (P < 0.01) and be over the age of 60 (P < 0.01). Of those patients with low literacy, 67.4% admitted having trouble reading and understanding what they read. Almost 40% (n = 23) of patients with low functional literacy who acknowledged they have trouble reading admitted shame. Of the 58 patients who had low functional health literacy and admitted having trouble reading, 67.2% had never told their spouses, and 53.4% had never told their children of their difficulties reading. Nineteen percent of patients had never disclosed their difficulty reading to anyone. Many patients with reading problems are ashamed and hide their inability to read. Shame is a deeply harbored emotion that plays an important role in understanding how low literate patients interact with health care providers. Further research is needed to understand how providers should deal with the shame associated with low literacy.
