RESUMEN
Background: Complementary and alternative medicine (CAM) could be one option to address perceived insufficient milk (PIM), but there are few data comparing the effectiveness, acceptability, and safety of various CAM therapies. The purpose of this study was to describe and compare, among women delivering at 34-376/7 weeks, the feasibility and acceptability of two CAM interventions for treatment of PIM: (1) a meditation/relaxation intervention via an MP3 (Apple iPod Shuffle©) player and (2) a commercially available combination-blend herbal supplement (Motherlove: More Milk Plus Alcohol Free®). Materials and Methods: After randomization, over 9 days, women received three home visits from a lactation consultant, recorded pre/post intervention test weights and expressed milk volume, tracked daily breastfeeding behavior, and completed an end-of-study interview about the interventions. Women in each group were offered the other group's intervention on study day 9. Breastfeeding status and intervention continuation were assessed at 2 months. Results: Of 183 women screened, 11 were eligible, enrolled into, and completed the 9-day trial. Six women were randomized to the herbal supplement and 5 to meditation. One participant (meditation) stopped breastfeeding on study day 8. At 2 months, 3 of 6 women assigned to the herbal supplement and 3 of 5 women assigned to meditation were still breastfeeding; 1 (herbal supplement) was exclusively breastfeeding. Most participants were adherent to the prescribed protocols for both interventions. Interventions were generally perceived as safe, with benefits not necessarily related to increased milk supply. Conclusion: Mothers of late preterm and early term infants who had PIM found the CAM interventions acceptable and safe. The effect of CAM therapies on breastfeeding outcomes, with and without in-home lactation assistance, requires further investigation.
RESUMEN
Incidences of low-trauma fractures among osteopenic women may be related to changes in bone quality. In this blinded, prospective-controlled study, compositional and heterogeneity contributors of bone quality to fracture risk were examined. We hypothesize that Raman spectroscopy can differentiate between osteopenic women with one or more fractures (cases) from women without fractures (controls). This study involved the Raman spectroscopic analysis of cortical and cancellous bone composition using iliac crest biopsies obtained from 59-cases and 59-controls, matched for age (62.0 ± 7.5 and 61.7 ± 7.3 years, respectively, p = 0.38) and hip bone mineral density (BMD, 0.827 ± 0.083 and 0.823 ± 0.072 g/cm3, respectively, p = 0.57). Based on aggregate univariate case-control and odds ratio based logistic regression analyses, we discovered two Raman ratiometric parameters that were predictive of past fracture risk. Specifically, 1244/1268 and 1044/959 cm-1 ratios, were identified as the most differential aspects of bone quality in cortical cases with odds ratios of 0.617 (0.406-0.938 95% CI, p = 0.024) and 1.656 (1.083-2.534 95% CI, p = 0.020), respectively. Both 1244/1268 and 1044/959 cm-1 ratios exhibited moderate sensitivity (59.3-64.4%) but low specificity (49.2-52.5%). These results suggest that the organization of mineralized collagen fibrils were significantly altered in cortical cases compared to controls. In contrast, compositional and heterogeneity parameters related to mineral/matrix ratios, B-type carbonate substitutions, and mineral crystallinity, were not significantly different between cases and controls. In conclusion, a key outcome of this study is the significant odds ratios obtained for two Raman parameters (1244/1268 and 1044/959 cm-1 ratios), which from a diagnostic perspective, may assist in the screening of osteopenic women with suspected low-trauma fractures. One important implication of these findings includes considering the possibility that changes in the organization of collagen compositional structure plays a far greater role in postmenopausal women with osteopenic fractures.
