Maternal diet during breastfeeding in correlation to calcium and phosphorus concentrations in human milk

alexandrossfakianakis shared this article with you from Inoreader Maternal diet during breastfeeding in correlation to calcium and phosphorus concentrations in human milk via Journal of Human Nutrition and Dietetics Abstract Background The impact of maternal diet on minerals concentration in human milk (HM) remains unclear. The main aim of this study was to investigate the relationship between maternal dietary intake and calcium and phosphorus concentrations in HM. Furthermore, we aimed to evaluate the intake of both minerals by exclusively breastfed infants. Methodology HM samples were obtained from 30 mothers at 6-8 weeks postpartum. Each mother was asked to express pre- and post-feeding milk four times during 24-h period (6.00-12.00, 12.00-18.00, 18.00-24.00, 24.00-6.00). Maternal dietary assessment was based on food frequency questionnaire and 3-day dietary records. Analyzed minerals were determined by inductively coupled plasma mass spectrometer (NexION 300D ICP Mass Spectrometer, Perkin Elmer SCIEX, USA). Results The mean concentrations of calcium and phosphorus in HM samples were 278.7 ± 61.0 mg/L and 137.1 ± 21.9 mg/L, respectively, maintaining 2:1 ratio b y weight. The concentration of both minerals was correlated with each other (r=0.632, p=<0.001). The infants' mean calcium intake was 149.53 ± 36.41 mg/L and for phosphorus it was 74.62 ± 19.41 mg/L. The risk of insufficient intake of calcium was reported in 60% of infants (n=18). Spearman/Pearson correlation coefficients did not reveal any correlations between HM calcium concentration and maternal diet, contrary to HM phosphorus concentration, which was positively correlated with energy (r=0.369, p=0.045), total protein (r=0.464, p=0.01), calcium (r=385, p=0.036), phosphorus (r=501, p=0.005), niacin (p<0.001) and pyridoxine (r=382, 0.037) intake. However, in multivariable analysis we observed that maternal dietary intake of both minerals had positive influence on their concentration in HM. Conclusion Maternal calcium and phosphorus intake influenced concentration of both minerals in HM, however the relationship was rather weak. Additionally, we observed that c alcium intake by most of the exclusively breastfed infants was insufficient to meet the recommended daily intake. This article is protected by copyright.

Optimizing SARS-CoV-2 Pooled Testing Strategies Through Differentiated Pooling for Distinct Groups

alexandrossfakianakis shared this article with you from Inoreader Optimizing SARS-CoV-2 Pooled Testing Strategies Through Differentiated Pooling for Distinct Groups via American Journal of Epidemiology - Advance Access Abstract Pooled testing has been successfully used to expand SARS-CoV-2 testing, especially in settings requiring high volumes of screening of lower-risk individuals, but efficiency of pooling declines as prevalence rises.We propose a differentiated pooling strategy that independently optimizes pool sizes for distinct groups with different probabilities of infection to further improve the efficiency of pooled testing. We compare the efficiency (results obtained per test kit used) of the differentiated strategy to a traditional pooling strategy in which all samples are processed using uniform pool sizes under a range of scenarios.For most scenarios, differentiated pooling is more efficient than traditional pooling. In scenarios examined here, an improvement in efficiency of up to 3.94 results per test kit could be obtained through differentiated versus traditional pooling, with more likely scenarios resulting in 0.12 to 0.61 additional results per kit. Und er circumstances similar to those observed in a university setting, implementation of our strategy could result in an improvement in efficiency between 0.03 to 3.21 results per test kit.Our results can help identify settings, such as universities and workplaces, where differentiated pooling can conserve critical testing resources.

Using indocyanine green angiography to achieve complete engraftment of pectoralis major myocutaneous flaps

alexandrossfakianakis shared this article with you from Inoreader Using indocyanine green angiography to achieve complete engraftment of pectoralis major myocutaneous flaps via International Journal of Oral and Maxillofacial Surgery via MedWorm.com This report describes the usefulness of indocyanine green angiography (ICGA) to achieve complete engraftment of the PMMC flap. Five patients with oral cancer underwent reconstruction with a PMMC flap after cancer ablation. During the skin paddle design and flap elevation, the blood supply to the flap was assessed by ICGA.
