The role of inadequate health literacy skills in colorectal cancer screening.

Colorectal cancer is ideally suited for early detection strategies that are likely to improve survival rates. Screening with either a fecal occult blood test (FOBT) or flexible sigmoidoscopy has been shown to identify precancerous polyps or cancers in early stages. However, persons with limited education and of lower socioeconomic status infrequently participate in screening programs in general and have very low rates of colorectal screening. Low literacy, which is common among persons with limited education and low income, may be an overlooked factor in understanding patients' decision making about colorectal cancer screening. This article provides information from focus groups about colorectal cancer screening, which we examine in the context of relevant literature on cancer screening and literacy. Using the health belief model, we examine the association between inadequate health literacy skills and low rates of colorectal cancer screening. The theoretical model also provides insights into strategies for improving knowledge, attitudes, and beliefs and screening rates for this challenging patient population.

Childhood vaccine risk/benefit communication in private practice office settings: a national survey.

UNLABELLED: Communication about childhood vaccine risks and benefits has been legally required in pediatric health care for over a decade. However, little is known about the actual practice of vaccine risk/benefit communication. OBJECTIVES: This study was conducted to identify current practices of childhood vaccine risk/benefit communication in private physician office settings nationally. Specifically, we wanted to determine what written materials were given, by whom, and when; what information providers thought parents wanted/needed to know, the content of nurse and doctor discussion with parents, and the time spent on discussion. We also wanted to quantify barriers to vaccine risk/benefit discussion and to prioritize materials and dissemination methods preferred as solutions to these barriers. METHODS: We conducted 32 focus groups in 6 cities, and then administered a 27-question cross-sectional mailed survey from March to September 1998, to a random national sample of physicians and their office nurses who immunize children in private practices. Eligible survey respondents were active fellows of the American Academy of Pediatrics or American Academy of Family Physicians in private practice who immunized children and a nurse from each physician's office. After 3 mailings, the response rate was 71%. RESULTS: Sixty-nine percent of pediatricians and 72% of family physicians self-reported their offices gave parents the Centers for Disease Control and Prevention Vaccine Information Statement, while 62% and 58%, respectively, gave it with every dose. In ~70% of immunization visits, physicians and nurses reported initiating discussion of the following: common side effects, when to call the clinic and the immunization schedule. However, physicians reported rarely initiating discussion regarding contraindications (<50%) and the National Vaccine Injury Compensation Program (<10%). Lack of time was considered the greatest barrier to vaccine risk/benefit communication. Nurses reported spending significantly more time discussing vaccines with parents than pediatricians or family physicians (mean: 3.89 vs 9.20 and 3.08 minutes, respectively). Both physicians and nurses indicated an additional 60 to 90 seconds was needed to optimally discuss immunization with parents under current conditions. Stratified analysis indicated nurses played a vital role in immunization delivery and risk/benefit communication. To improve vaccine risk/benefit communication, 80% of all providers recommended a preimmunization booklet for parents and approximately one half recommended a screening sheet for contraindications and poster for immunization reference. The learning method most highly endorsed by all providers was practical materials (80%). Other desirable learning methods varied significantly by provider type. CONCLUSIONS: There was a mismatch between the legal mandate for Vaccine Information Statement distribution and the actual practice in private office settings. The majority of providers reported discussing some aspect of vaccine communication but 40% indicated that they did not mention risks. Legal and professional guidelines for appropriate content and delivery of vaccine communication need to be clarified and to be made easily accessible for busy private practitioners. Efforts to improve risk/benefit communication in private practice should take into consideration the limited time available in an office well-infant visit and should be aimed at both the nurse and physician.

Perinatal lactation protocol and outcome in mothers with and without insulin-dependent diabetes mellitus.

This study compared the course of lactation from days 2 to 84 postpartum in 33 women with insulin-dependent diabetes mellitus (IDDM); 33 women without diabetes selected by using gestational age of the infant, method of delivery, sex of the infant, and prior lactation experience as a means of ensuring similar patterns in factors known to influence success (control subjects); and 11 healthy reference subjects who delivered vaginally. Nutritionists visited the mothers on days 2, 3, 7, 14, 42, and 84 postpartum; obtained prenatal and perinatal medical information; and questioned the mothers on their breast-feeding experience. Women with IDDM were able to establish lactation despite postpartum separation from their infants, delays in the start of breast-feeding, reduced frequency of feeding, increased use of supplemental feedings, and the high rate of cesarean section. Clinicians must recognize the need to provide appropriate counseling so that mothers with IDDM will not be discouraged by problems with breast-feeding.

Delayed lactogenesis in women with insulin-dependent diabetes mellitus.

Breast milk lactose, total nitrogen, conductivity, osmolality, and intake by infants of 33 women with insulin-dependent diabetes mellitus (IDDM), 33 control women without diabetes, and 11 reference women were determined in a 3-mo study of lactation. Milk of women with IDDM had significantly lower lactose and higher total nitrogen (2-3 d postpartum), and their infants had significantly less milk intake (7-14 d postpartum) than did control or reference women. Total nitrogen was negatively correlated with milk lactose for women with IDDM at all times and for control women through day 14 postpartum. The data indicate delayed lactogenesis for women with IDDM, which was more likely to occur with poor metabolic control. Differences in milk composition of women with IDDM do not preclude them from breast-feeding their infants.

Antenatal sonographic findings in a case of intra-abdominal pulmonary sequestration.

This report describes the antenatal sonographic identification of a hyperechoic intra-abdominal mass in a 30-week fetus. The mass was proved by autopsy to be an extralobar pulmonary sequestration. Although a rare type of congenital malformation, pulmonary sequestration should be included in the differential diagnosis of an echodense intra-abdominal mass seen during antenatal ultrasound examination.

Detection of hearing loss with ipsilateral acoustic reflex thresholds.

This study consisted of two experiments both of which involved measurement of the ipsilateral acoustic reflex threshold (ART). In Experiment I, ipsilateral ARTs were measured in normal-hearing adults for a 2 000-Hz tone and computer-generated complex stimuli of varying bandwidth. Results of this experiment revealed that the bandwidth effect for the ipsilateral ART was similar to the contralateral effect. The ART decreased monotonically as a function of bandwidth of the reflex-eliciting stimulus. Results of Experiment II indicated that ipsilateral ARTs successfully differentiated between normal hearing and significant hearing loss, in difficult-to-test groups of young children, when used with the bivariate plotting procedure. In addition, obtaining reflexes ipsilaterally, rather than contralaterally, appeared to have advantages with this population. The ipsilateral test apparatus is less cumbersome, the possibility of calibration error from a malpositioned contralateral earphone is eliminated and the children were generally more accepting of the ipsilateral assembly.

The effects of maternally administered magnesium sulfate on the neonate.

The effects of parenterally administered magnesium sulfate on maternal and neonatal calcium and magnesium metabolism in nonasphyxiated, term pregnancies complicated by pregnancy-induced hypertension were studied prospectively. In addition, the neurobehavioral effects of neonatal hypermagnesemia were investigated by means of a neonatal assessment scale that specifically measures reflex activity and both passive and active muscle tone. Maternal magnesium sulfate infusion was associated with maternal and neonatal hypermagnesemia when compared with that of control subjects (1.8 +/- 0.10 to 3.6 +/- 0.5 mg/dl, p less than 0.001, and 1.75 +/- 0.2 to 3.6 +/- 0.5 mg/dl, p less than 0.005, respectively). Maternal serum calcium levels fell with magnesium therapy (9.3 +/- 0.18 to 7.9 +/- 0.1 mg/dl, p less than 0.001), while neonatal calcium levels were unaffected (10.8 +/- 0.44 to 10.5 +/- 0.38 mg/dl, p less than 0.05). Neurological status examinations in the neonate were similar in both the control and treatment groups. In addition, neurological performance of the neonate did not correlate with cord magnesium levels or to the total dose of magnesium administered.
