Expanded Newborn Screening: Information and Resources for the Family Physician.

Each year, 4 to 5 million newborns receive state-mandated screening. Although the Advisory Committee on Heritable Disorders in Newborns and Children has identified 34 core conditions that should be incorporated into screening programs, each state manages, funds, and maintains its own program. State programs encompass screening, as well as the diagnosis and coordination of care for newborns with positive findings. Testing for core disorders is fairly standardized, but more extensive screening varies widely by state, and the rigorous evaluation of new screening panels is ongoing. The core panel includes testing for three main categories of disorders: metabolic disorders (e.g., amino acid and urea cycle, fatty acid oxidation, and organic acid disorders); hemoglobinopathies; and a group of assorted conditions, including congenital hearing loss. Family physicians must be familiar with the expanded newborn screening tests to effectively communicate results to parents and formulate interventions. They must also recognize signs of metabolic disorders that may not be detected by screening tests or that may not be a part of standard newborn screening in their state. For infants with positive screening results leading to diagnosis, long-term follow-up involves ongoing parental education, regular medical examinations, management at a metabolic treatment center, and developmental and neuropsychological testing to detect associated disorders in time for early intervention.

A view from Cheyenne Mountain: Generation III's perspective of Keystone III.

In October 2000 the family of family medicine convened the Keystone III conference at Cheyenne Mountain Resort. Keystone III participants included members of Generation I (entered practice before 1970), Generation II (entered 1970-1990), and Generation III (entered after 1990). They represented a wide range of family physicians, from medical students to founders of the discipline, and from small-town solo practice to academic medicine. During the conference, the three generations worked together and separately thinking about the past, present, and future of family medicine, our roles in it, and how the understanding of a family physician and our discipline had and would continue to evolve. After the conference, the 10 Generation III members wrote the article published here, reflecting on our experiences as new physicians and physicians in training, and the similarities and differences between our experiences and those of physicians in Generations I and II. Key similarities included commitment to whole-person care, to a wide scope of practice, to community health, and to ongoing engagement with our discipline. Key differences included our understanding of availability, the need for work-life balance, the role of technology in the physician-patient relationship, and the perceptions of the relationship between medicine and a range of outside forces such as insurance and government. This article, presented with only minor edits, thus reflects accurately our perceptions in late 2000. The accompanying editorial reflects our current perspective.

Menopause.

Public awareness of the benefits of a healthy transition through menopausal and postmenopausal stages offers women a new perspective on aging and empowers them to take greater responsibility for their own health and well-being. Primary care physicians are a chief influence on information regarding health behaviors, risk assessment, and medical interventions that preserve health and that prevent premature death and disability. Clinicians can help identify therapy goals for short-term relief of menopausal symptoms and long-term relief and prevention of osteoporosis and fractures. Physicians must consider individual needs and concerns and be cognizant that because a woman's needs can change, re-evaluation is needed.

How primary care providers might review evidence on hydration.

Primary care providers (PCPs) are increasing their use of evidence-based medicine (EBM) in the care they give patients. They evaluate the available evidence to determine if it applies to their patients and seek to complement their clinical experience with EBM to improve patient outcomes. In evidence-based practices, patient oriented data are valued more highly than disease oriented evidence. More than 8 million biomedical articles are published annually, but only an estimated 2% of those are relevant to improved patient outcomes (POEMs - patient oriented evidence that matters). This paper describes some of the tools used by PCPs to search for evidence and the decision-making process used to determine if they will change their practice. Understanding how PCPs evaluate research findings and other evidence can help hydration researchers frame their research questions and study reports.

Prenatal smoking cessation among Black and White women in Eastern North Carolina.

PURPOSE: Limited information is available about Black:White disparities in prenatal smoking cessation, and the results of prior research are inconsistent. We analyzed smoking cessation and factors associated with cessation (attitudes, environment, and nicotine addiction) in a sample of pregnant Black and White women. METHODS: Women were interviewed at the first prenatal visit at two hospital-based clinics. RESULTS: Among former and current smokers, there were no significant differences in the percentage of former smokers between Black (46.8%) and White (43.3%) pregnant women, or in the percentage of "spontaneous quitters" (i.e., those who quit after learning that they were pregnant) for Blacks (36%) and Whites (28%). Both Black and White spontaneous quitters had evidence of occasional relapses to smoking. For Black and White women, smoking more than a pack a day prior to pregnancy was associated with smoking during pregnancy. DISCUSSION: Among current and former smokers, spontaneous cessation was about the same for Black and White women, and about two thirds of women who were smokers when they learned of the pregnancy continued to smoke during pregnancy. Nicotine addiction contributed to continued smoking.

Factors associated with prenatal smoking among black women in eastern North Carolina.

OBJECTIVES: The objective of this research was to explore prenatal smoking behaviors among Black women attending prenatal clinics. Despite the racial disparities in poor pregnancy outcomes, and the well-known association of smoking with harmful outcomes, little research has been conducted about prenatal smoking among Black women. METHODS: Women were enrolled in the study and interviewed at the time of the first prenatal visit. The interview contained items to assess prenatal smoking and cessation, depressive symptoms, demographic factors, and beliefs about smoking. Reports of smoking cessation were verified using urinary cotinine. RESULTS: The sample consisted of 811 Black women. Fourteen percent of the women were self-reported smokers, 12.6% reported cessation and 73% were nonsmokers. Twenty percent of the self-reported quitters had elevated cotinine; when these women were reclassified, 17% of the women were smokers. Factors associated with smoking in logistic regression analysis included elevated maternal depressive symptoms (OR = 1.7, 95% CI: 1.1-2.6), maternal age 20 years or older (OR = 1.94; 95% CI: 1.1, 3.3), less than a high school education (OR = 2.2; 95% CI: 1.2, 3.8), unmarried/not living with a partner (OR = 1.9; 95% CI: 1.0, 3.6), and allowing smoking in the home (OR = 5.5; 95% CI: 3.4, 8.6). CONCLUSIONS: The prevalence of maternal prenatal smoking was much higher among women in this sample than has been previously reported. The rate of nondisclosure of smoking among self-reported quitters was also high. Maternal behavioral (allowing smoking in the home) and psychosocial factors (depressive symptoms) were associated with prenatal smoking.

Emergency contraception.

Women can use emergency contraception to prevent pregnancy after known or suspected failure of birth control or after unprotected intercourse. Many patients do not ask for emergency contraception because they do not know of its availability. Emergency contraception has been an off-label use of oral contraceptive pills since the 1960s. Dedicated products, the Yuzpe regimen (Preven) and levonorgestrel (Plan B), were marketed in the United States after 1998 but had been available in Europe for years before that. A third approved method of emergency contraception is the insertion of an intrauterine device. Emergency contraception is about 75 to 85 percent effective. It is most effective when initiated within 72 hours after unprotected intercourse. The mechanism of action may vary, depending on the day of the menstrual cycle on which treatment is started. Despite the large number of women who have received emergency contraception, there have been no reports of major adverse outcomes. If a woman becomes pregnant after using emergency contraception, she may be reassured about the lack of negative effects emergency contraception has on fetal development. It may be beneficial for physicians to offer an advance prescription for emergency contraception at a patient's regular gynecologic visit to help reduce unwanted pregnancies. Advance provision of emergency contraception can increase its use significantly without adversely affecting the use of routine contraception.
