Abstract
Despite goat milk having health benefits over cow milk, goat milk yogurt (GY) presents low consistency and viscosity, which reduces its overall acceptability by the consumer. Thus, new innovative methods can be an alternative to improve the quality of GY. Hence, this study aimed to investigate the effect of ultrasound (US) treatment with different sonication times on quality parameters of probiotic GY during refrigerated storage. US treatment was conducted at 20 KHz for 3, 6, and 9 min in yogurt. Lactobacillus bulgaricus and Lactobacillus acidophilus LA-5 were sensitive to US treatment, presenting a decrease in the yogurts stocked. This loss of viability led to reduced post-acidification due to smaller lactose metabolization in yogurt samples submitted to the US. Among tested treatments, the application of 6 min enhanced the apparent viscosity and consistency index of GY yogurts. In addition, this time also reduced tyramine and total biogenic amine (BAs) content. These findings suggest that 6 min of sonication is a promising way to improve the rheological properties and reduce the acidity and BAs content in GY. Further studies should be performed to optimize the US setting conditions to preserve the probiotic culture viability in yogurts.

Abstract
A child with osteogenic sarcoma of the sacral spine has complex nursing and interdisciplinary team needs. The course of one patient is discussed, both from the patient and family's perspective and that of her inter-disciplinary care team. The need for a coordinated, holistic approach to care that involves advance planning, continual reassessment of goals, and clear communication among the team members and consulting services is clearly demonstrated.

Abstract
Conflicting results have been reported regarding the association of formula samples given at hospital discharge with breastfeeding duration. This study investigated the relationship between the distribution of formula samples and breastfeeding duration in low-income Hispanic women. A gift pack of formula was distributed randomly to 88 breastfeeding women. All women received a telephone call at one and three weeks to collect information about infant feeding. Chi-square analysis revealed no significant difference in the proportion of women exclusively breastfeeding at one week. However, fewer women were exclusively breastfeeding in the gift pack group at three weeks (p less than .004). Gift packs given to Hispanic breastfeeding women are associated with a decrease in exclusively breastfeeding during the first three weeks postpartum.
