Effects of rise in food costs on hemoglobin concentrations of early school-age children, 1972-75.
In a hematologic survey conducted in 1972, microcythemia in school children was found to be associated with microcythemia in other family members. The association of cultural characteristics of chronic poverty with reduced red cell volume suggested nutritional iron deficiency. A resurvey of families was made in 1975. For 39 children between the ages of 3 and 10 years at the time of both surveys, mean hemoglobin concentration (HGB) decreased from 21.0 g/dl to 10.8 g/dl. Thirteen infants, 6 months to 3 years of age in 1972, in the resurveyed families had mean HGB of 11.5 g/dl as compared to 10.4 g/dl for 9 similarly aged children newly born into the resurvey families. The rate of somatic growth was unchanged during the interval between survey. During the interval between 1972 and 1975, food costs rose nationally, and the purchase of meat products decreased both nationally and (as found in this study) locally. The data suggest that the high cost of foods rich in micronutrients may increase the prevalence of iron deficiency in an impoverished community.

Hepatitis and HIV: interrelationship and interactions.
Hepatitis in the context of HIV infection is commonplace, but the causative agent is not always readily identifiable. This review highlights the differential diagnosis of hepatitis in that context, examining the interrelationships and interactions between the four main hepatitis viruses and HIV.

A Western Australian Delphi survey of staff development research priorities.
A modified Delphi survey conducted during 1989-1990 identifies problems that Western Australian nurses consider research priorities. Participants were employed in hospital and health-care agencies throughout metropolitan and rural regions of the state. The large number of topics generated were analyzed and categorized into three areas of nursing: staff development, clinical practice, and management. Participants rated each topic on its importance to nurses and patients. The results are based on the 10 priority items identified in the staff development field.

Maternal and paternal risk factors and adverse neonatal outcomes among Hispanic subgroups in Illinois (1989 through 1993).
OBJECTIVES: The study purposes were to examine maternal and paternal high-risk factors and note associated differences in birth outcomes among Hispanic subgroups compared with white and black populations in Illinois. STUDY DESIGN: Computerized birth certificate data of 131,768 Hispanic singleton neonates (14.1% of all Illinois births from 1989 through 1993) were compared among five Hispanic subgroups. Matched infant birth-death computerized files were obtained for neonatal and postneonatal mortality (1989 through 1992 birth cohorts) and separate fetal mortality tables were also examined. RESULTS: Whereas Puerto Rican mothers had higher prevalence rates for various maternal risk factors and higher infant morbidity rates among the five Hispanic groups, infants of Cuban mothers had significantly higher fetal and infant mortality rates. CONCLUSIONS: Our study identified substantial differences during the prenatal period and in birth outcomes among the five Hispanic subgroups. Those differences may help us develop innovative targeted interventions.

Comparison of two methods of surfactant administration and the effect on dosing-associated hypoxemia.
OBJECTIVE: The purpose of our study was to test the hypothesis that surfactant dosing through a proximal sideport adapter on an endotracheal tube leads to more dosing-associated hypoxemia compared with a method of dosing that uses a double-lumen endotracheal tube. STUDY DESIGN: Using adequate sample size to compare significant changes in O2 saturation (power > 0.8, alpha < 0.05) we enrolled 36 infants with respiratory distress syndrome in this randomized trial. A 10% change in O2 saturation was considered clinically significant. Nineteen infants received 38 doses of surfactant through the sideport adapter. Seventeen infants received 31 doses of surfactant through the nonventilation lumen of a double-lumen endotracheal tube. Two main outcome measures were assessed: time-averaged O2 saturation values 30 minutes after dosing and the largest absolute fall in O2 saturation for each patient. RESULTS AND CONCLUSIONS: Time-averaged O2 saturation measures were higher in the proximal sideport group (p = 0.02), but the magnitude of difference was probably not clinically significant. No significant difference was detected between groups when we compared largest absolute drop in O2 saturation. Secondary analyses found no effect of birth weight or dose number (second vs third dose) on either outcome measure.
