Early human milk feeding is associated with a lower risk of necrotizing enterocolitis in very low birth weight infants.

BACKGROUND: Necrotizing enterocolitis (NEC) is a frequent cause of mortality and morbidity in very low birth weight (VLBW) infants. Human milk (HM) feeding has been associated with lower risk of NEC. However, mothers of VLBW infants often experience insufficient milk production, resulting in mixed feedings of HM and formula. Moreover, medical complications often limit the volume of feeding they can be given. OBJECTIVE: To determine if high proportions of (50% or greater) HM enteral feeding within the first 14 days of life are protective against NEC. METHOD: This was a prospective cohort study of VLBW infants who were grouped according to the HM proportion of enteral feeding in the first 14 days: <50% (low human milk, LHM, n=46) and > or =50% (high human milk, HHM, n=156). The outcome of interest was development of NEC (Bell stage 2 or 3). Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) and to assess potential confounding due to perinatal risk factors. RESULT: Two hundred and two infants were studied. Confirmed NEC occurred in 5/46 (10.6%) of the LHM group, as compared with 5/156 (3.2%) of the HHM. Gestational age was the only perinatal factor associated with risk of NEC. After adjustment for gestational age, HHM was associated with a lower risk of NEC ((OR=0.17, 95% CI: 0.04 to 0.68), P=0.01). CONCLUSION: Enteral feeding containing at least 50% HM in the first 14 days of life was associated with a sixfold decrease in the odds of NEC.

In-home continuing care services for substance-affected families: the bridges program.

Addressing substance abuse in families is an important concern for the social work field. This article presents a preliminary view of a continuing care substance abuse recovery services program designed to assist the substance-affected family. The intervention approach is a blended model of substance abuse recovery work and family preservation. Services are directed at helping substance-abusing parents with "recovering" their role with their families, developing support for their recovery work, and helping them gain the education and skills they need for effective parenting, supportive family involvement, and avoidance of drugs and alcohol. The program focuses on helping substance abusers and their families achieve relapse prevention by addressing functioning in four domains: individual actions and cognitions, individual recovery actions, family actions and cognitions, and family recovery actions. The article presents two case examples to highlight the efficacy of the intervention model and the general positive effect continuing care services are having on substance-affected families.

Identifying determinants of risk of sexual victimization of youth: a multivariate approach.

The present study argues that a greater understanding of the factors which contribute to a youth's sexual victimization is likely to not only be based on what we know about the youths who are victimized but also on comparative information on youths who are not. Selected social background variables from a sample of young victims (n = 20) and nonvictims (n = 21) representing a population of youths with histories of antisocial behavior were compared. Using stepwise discriminant analysis several factors relating to youths' home environment significantly discriminated victims from nonvictims. The results suggest that the probability of being sexually victimized is increased when the home environment is unstable and lacks adequate control over youths' activities. The need for improved research methodologies to achieve better identification of determinants of risk is discussed. Multivariate assessment of social, situational, and personal factors of victims and nonvictims is recommended as a potentially promising approach for improving current rape prevention efforts.

Instigative aggression as a function of past experience and target characteristics.

Third-party-instigated aggression was examined by manipulating the provocativeness of the same or a new target in Part 2 of a task. Effects of previous experience with aggression (i.e., interacting with partners supportive of or disapproving of aggression in Part 1) were also examined. Although the provocativeness of the target accounted for the most variance in the amount of aggression expressed, when the target in Part 2 was new, prior experience influenced aggression. Results are discussed in terms of and interactional model of behavior. The clearer the current situational demands (i.e., known, predictable target) were, the less the influence of past aggressive experience on continued aggression; the more ambiguous the current situation (i.e., new, unpredictable target) was, the more the influence of past aggressive experience on continued aggression.

Factor and discriminant analysis of the Bem Sex-Role Inventory.

Several studies have recently recommended that items which fail to load substantially (< .40) on one of several primary factors characterizing the Bem Sex-Rote Inventory (BSRI) could be deleted without substantial loss of interpretability. This recommendation is questioned on the basis that the extent of interrelatedness of the items is an insufficient indicator of the contribution each item makes towards the classification (identifying sex-types by Bem's median split technique) efficiency of the inventory. Empirical support of this contention was provided by conducting several discriminant analyses (predicting sex-types) on a sample of 1117 BSRI protocols and excluding the various items suggested by the earlier research. These results were then compared with the results of a discriminant analysis using the 40 masculine and feminine items. The analyses using less. than all 40 items produced substantially poorer discrimination than when all 40 items were included. The results Suggest that decisions to exclude items on the basis of factor analysis may be inappropriate and risk serious loss of power in classifying individuals by sex-type.
