A new tetratertiary phosphine ligand and its use in Pd-catalyzed allylic substitution.

A new tetraphosphine, the cis-cis-cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane (Tedicyp) 1 has been synthesized, characterized, and used in Pd-catalyzed allylic substitutions. The Tedicyp was easily prepared in seven steps from the commercially available himic anhydride. The structure of the complex Tedicyp-borane was determined by X-ray analysis. The tetraphosphine in combination with [Pd(eta(3)-C(3)H(5))Cl](2) affords a very efficient catalyst for allylic substitution of several allylic acetates. Under mild conditions, very high turnover numbers and turnover frequencies have been obtained.

Comparison of internal medicine, pediatric, and medicine/pediatrics applicants and factors influencing career choices.

BACKGROUND: A reemergence of medical students choosing primary care is occurring, with medicine/pediatrics as an increasingly popular option. We compared applicants to pediatrics, medicine, and medicine/pediatrics and the factors that influence career choice. METHODS: We designed a survey to gather objective data and information shown to influence career choices. Applicants interviewing in our three primary care programs completed the survey. RESULTS: Pediatric applicants were more likely to be women and to choose their career in the 2nd year of medical school. Medicine/Pediatrics applicants had the highest interest in practicing primary care and in pursuing an academic career. However, they had the smallest number of role models. The average education debt was the same. CONCLUSION: Differences in applicants applying to primary care programs may be used to target particular applicants and to counsel medical students on career choice.

A curriculum for teaching clinical ethics in neonatal-perinatal medicine.

Ethical thought plays a role in clinical decision-making, especially in fields such as neonatal-perinatal medicine. There is limited information, however, on the best way to teach ethics to postgraduate medical trainees in this subspeciality. This article describes the development, implementation, and evolution of a structured curriculum in ethics for a program in neonatal-perinatal medicine. The curriculum is facilitated by a specialist in ethics and based on hypothetical case scenarios, which are discussed using a framework that highlights the ethical values promoted or neglected in each decision option. Formal evaluation of the program has been impossible, but informal reviews indicate that there is a high degree of satisfaction.

[Contributions of ethics to the practice of intensive care].

Intensive care, one of the greatest achievements of modern medicine, is not without its problems. In what sense could ethics contribute towards an intensive care medicine which would be humane and respectful of what it means to be sick? After having presented a phenomenology of what it means to be sick and in intensive care, the author proposes an ethical framework which could guide the decision-making of physicians specialized in the field. This framework has three levels. Level one deals with the basic values of benevolence and autonomy which are those of medicine itself. Level two deals with the implementation of these values, which bioethics sees as conflicting. Implementation is achieved by "conversation" between the physician and the patient. Finally, the physician is invited to question his or her own attitude towards the unavoidable dilemmas created by the paradoxes and contradictions of modern medicine.

Iron status and intake of older infants fed formula vs cow milk with cereal.

One hundred four infants were randomly assigned to receive whole cow milk plus iron-fortified cereal (WCM + C) in accord with the previous recommendations of the Committee of Nutrition/American Academy of Pediatrics (CON/AAP); one of two iron-fortified, follow-up formulas; or an iron-fortified infant formula. Mean iron intakes and vitamin C exceeded the recommended dietary allowance in all groups. By 12 mo of age, mean ferritin and mean corpuscular volume were lower in the WCM + C group and significantly more infants had serum ferritin concentrations < 12 micrograms/L. We conclude that infants 6-12 mo of age fed whole cow milk and iron-containing table food are at risk of developing depleted iron stores but not anemia. The iron insufficiency in these infants is not due to inadequate intake of iron or vitamin C, but probably to relatively poor bioavailability of iron in infant cereal.

Low birth weight and household structure.

Data collected during postnatal visits were used to study the risk of low birth weight (LBW) among unmarried women living alone and among unmarried women living with a partner or another adult, using married women living with their husbands as the reference group. Information on 1,627 singleton live births was included in a binomial regression, controlling for seven potential confounding variables: mother's age, education, gestational weight gain, parity, smoking status, and presence of medical problems preceding or during pregnancy. Unmarried women living alone were at greater risk of bearing a LBW infant than married women living with their husbands (RR = 2.0, 95% Cl = 1.2-3.4). Unmarried women living with a partner had a slightly lower risk of LBW than married women (RR = 0.6, 95% Cl = 0.3-1.3) and unmarried women living with another adult had a slightly increased risk (RR = 1.3, 95% Cl = 0.6-3.0), although neither of these results was statistically significant. On the basis of these findings, we suggest that public health interventions should target women according to their household structure rather than their marital status.

Risk of low birthweight and prematurity among foreign-born mothers.

Data collected during postnatal visits were used to study the risk of low birthweight (LBW) and prematurity among foreign-born mothers and mothers born in Canada. 2,913 singleton live births were included in the analysis. Odds ratios (OR) and 95% confidence intervals (CI) for LBW and prematurity were estimated using a logistic regression model. Foreign-born mothers did not have a higher risk of LBW or prematurity as compared to native-born mothers (OR = 1.1, 95% CI = 0.8-1.5; OR = 1.0, 95% CI = 0.7-1.4, respectively). For both LBW and prematurity, women in the intermediate category of length of stay (1-3 years) had a somewhat lower risk and women with the shortest length of stay (less than one year) had a slightly higher risk than women with the longest length of stay (more than 3 years). However, none of these results was statistically significant. Results of this study suggest that foreign-born mothers do not have a higher risk than Canadian-born mothers of bearing a LBW or premature infant. This finding differs from the widespread perception that immigrant mothers are at high risk for adverse birth outcomes.
