Introduction Human donor milk is widely used to feed premature and sick newborns when the milk of their own mothers is insufficient. All treatment processes involving human milk affect its composition. The aim of this study was to assess changes in the macronutrients and bioactive protein (lactoferrin and lysozyme) content in human milk caused by freezing and Holder pasteurization. Materials and Methods Milk samples were collected from 42 mothers 14-16 days after delivery. Each sample was divided into two parts and tested twice for macronutrient content, once upon being freshly collected and again after freezing at -40°C, thawing and Holder pasteurization. The lysozyme and lactoferrin concentrations were first determined in the unpasteurized thawed human milk after it was stored frozen at -80°C for up to 10 months and again after Holder pasteurization. The macronutrient concentrations were determined by midinfrared spectrophotometry, and enzyme-linked immunosorbent assay was used to measure the lysozyme and lactoferrin concentrations. Results Freezing and Holder pasteurization had no significant effects on the macronutrient concentrations. The mean lactoferrin content before and after pasteurization was 2.5 ± 1.07 and 0.03 ± 0.03 mg/mL, respectively (p  less then  0.001), and the lysozyme content was 19.57 ± 20.11 and 12.62 ± 14.14 μg/mL, respectively (p = 0.007). Conclusions Freezing and Holder pasteurization did not decrease the nutritional value of human milk but caused considerable loss of lactoferrin and lysozyme. New methods for treating human milk are needed that ensure the destruction of pathogenic microorganisms while retaining the biological and nutritional value of the milk.

Laparoscopic ventral hernia repair (LVHR) has been shown to decrease wound complications and length of stay (LOS) but results in more postoperative discomfort. The benefits of LVHR for the growing geriatric population are unclear. The aim of our study is to evaluate long-term outcomes and quality of life (QOL) after LVHR in the geriatric population.

A prospectively collected single-center database was queried for all patients who underwent LVHR (1999-2019). Age groups were defined as <40 (young), 40-64 (middle age), and ≥65 years (geriatric). QOL was assessed with the Carolinas Comfort Scale.

LVHR was performed in 1181 patients, of which 13.4% were young, 61.6% middle aged, and 25.0% geriatric. Hernia defect size (64.2 ± 94.4 vs 79.9 ± 102.4 vs 84.7 ± 110.0 cm

) and number of comorbidities (2.2 ± 2.1 vs 3.2 ± 2.2 vs 4.3 ± 2.2) increased with age (all

< .05). LOS increased with age (2.9 ± 2.5 vs 3.8 ± 2.9 vs 5.2 ± 5.3 days,

< .0001). Rates of postoperative cardiac events, pneumonia, respiratory failure, wound complication, reoperation, and death were similar (

> .05). Geriatric patients had increased rate of ileus and urinary retention (all

< .05). Overall recurrence rate was 5.7% with an average follow-up of 43.5 months, with no differences in recurrence between groups (

> .05). Geriatric patients had better overall QOL at 2 weeks (

= .0008) and similar QOL at 1, 6, and 12 months.

LVHR offers excellent results in the geriatric population. Despite having increased rates of comorbidities and larger hernia defects, which may relate to LOS, rates of complications and recurrence were similar compared with younger cohorts, with better short-term QOL.

Materials and Methods A secondary data analysis of the 2011-2012 National Survey of Children's Health was conducted (N = 29,829). Multivariate logistic regression was performed to estimate associations between predictor variables (parental emotional support, neighborhood social support, neighborhood safety, neighborhood amenities, and medical home) and breastfeeding outcomes (breastfeeding initiation [BFI] and exclusive breastfeeding for 6 months [EBF6m]). For predictor variables reaching statistical significance in the adjusted models, we performed subgroup analyses by race-ethnicity. Results After adjusting for individual- and family-level sociodemographic and maternal-child health factors, living in a neighborhood with 4 amenities was associated with 1.54 (95% confidence interval [CI] 1.06-2.23) times the odds of BFI, compared to children living in neighborhoods with no amenities. There was a negative association (adjusted odds ratio [aOR] 0.83; 95% CI 0.70-0.99) between neighborhood social support and BFI, although living in a supportive neighborhood was associated with 1.37 (95% CI 1.11-1.69) times the odds of EBF6m. There was a negative association (aOR 0.71; 95% CI 0.54-0.93) between perceived neighborhood safety and EBF6m. The observed associations differed by race-ethnicity. Conclusion Community-level structural and social support factors influence breastfeeding outcomes, independent of previously described individual level sociodemographic factors, and the observed associations differ by race-ethnicity. selleck screening library These findings have implications for the development of "breastfeeding-friendly" communities and public policies.Preterm and sick term infants are commonly fed with expressed breast milk (EBM) that has been subjected to various storage and handling conditions before feeding that may cause lipase-mediated elevation of free fatty acids (FFA). This study was designed to describe the variation, between mothers' and within the same mother over time, in the concentration of FFA in EBM used in an Australian neonatal unit. A total of 256 EBM samples, 149 freshly expressed in the unit cot-side and 87 expressed at home and brought in to the unit, were collected from 32 mothers with an infant admitted to the neonatal intensive and/or special care units at the Women's and Children's Hospital, Adelaide. Among the fresh EBM samples collected cot-side, the average total fat content was 29.78 ± 9.28 mg/mL, and the FFA concentration was 1.70% of total fats (interquartile range [IQR] 1.17-2.37%). Among the 10 mothers who provided fresh EBM at different stages of lactation, the concentration of FFA remained low overall, with some day-to-day variation (min 0.
