Objective: To determine influences on incidence of breast milk feeding (BMF) at time of discharge and 6 months later among infants cared for in the neonatal intensive care unit (NICU)., Design: A 2-year prospective descriptive NICU hospital-based cohort design., Setting: Academic Center Level III-IV NICU., Participants: Five hundred and thirty-five infants cared for in NICU and a subgroup of one hundred twenty-nine participant mothers who answered questionnaires., Methods: Predischarge data were collected using maternal and infant medical records. Post-discharge data were collected from maternal questionnaires., Results: At NICU discharge, biophysiologic stressors predictive of not receiving BMF included birth weight <1500 grams (p < .035), heart surgery (p = .014), and inhaled nitric oxide treatment (p = .002). Teenage mothers were less likely to BMF (p = .022). After discharge, BMF duration correlated with BMF duration of a prior infant (p < .009). Most mothers reported BMF >4 months, 91% continued pumping, and 89% indicated an interest in a hospital support group. Logistic regression analysis (R(2) 0.45) identified factors that significantly increased the likelihood of BMF > 4 months: BMF plan (p < .001), convenience (p = .018), and family as resource (p = .025). Negative associations were: awareness of immune benefits (p = .025), return to work (p = .002), and infants requiring surgical ligation of the patent ductus arterious (p = .019)., Conclusions: Social and medical stressors contribute to BMF duration pre- and post-NICU discharge. We speculate that active NICU BMF support targeting vulnerable infants and their families and assisting with plans for BMF pre- and post-discharge will help overcome barriers., (© 2012 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.)

Deficits in odor identification have been most frequently described in schizophrenia (SZ). A relationship between dysfunction in odor identification and negative symptoms of SZ has also been reported. Furthermore, deficit SZ (a subtype of the illness with primary, enduring negative symptoms) has been found to be associated with a particularly poor performance on odor identification tests indicating that deficits in smell identification could be differentially expressed in some subtypes of SZ. We describe correlations of performance on smell identification with positive and negative symptoms of SZ. Patients with SZ (n=15) and normal controls (n=19) were tested by the University of Pennsylvania Smell Identification Test (UPSIT). Psychopathology was assessed with the Scales for the Assessment of Positive and Negative Symptoms (SAPS and SANS). SZ patients performed more poorly on the UPSIT test than did normal controls. Consistent with previous findings, we observed a correlation of SANS with UPSIT performance. In particular, specific subdomains of SANS, such as blunted affect, apathy and anhedonia, were associated with odor identification deficits. Furthermore, UPSIT score predicts these subdomains of negative symptoms. No correlation was observed between positive symptom and odor identification deficits. Our study further reinforces a relation between olfactory identification deficit and negative symptoms in SZ and suggests that smell identification could be a candidate endophenotype relevant to negative symptoms of SZ., (Copyright 2009 Elsevier Ireland Ltd and the Japan Neuroscience Society.
