Urinary concentrations of non-essential and essential elements during weaning in infants from the NELA Cohort in Spain

Infancy is a period of continuous growth and development, where inadequate intake of essential elements and exposure to non-essential elements may have lifelong health consequences. Thus, the aim of this study is to evaluate the urine concentration of essential and non-essential elements as a proxy for internal exposure during the weaning period, from 3 to 18 months of age. The Nutrition in Early Life and Asthma (NELA) birth cohort generated the data for this study. Sociodemographic, dietary, and urine concentration of essential (Co, Cu, Mo, I, Fe, Mn, Se, Zn, and Ni) and non-essential elements (Al, V, As, Cd, Sb, Tl, and Pb) data were available for 490 participants at 3 months of age and 216 participants at 18 months of age. Paired urine samples at both time periods were available for 175 infants. At 3 months of age, exclusively breastfed infants had lower urine concentrations of Al, V, Fe, Co, Se, Sb, and Tl. Notably, the concentration of Mo had a median (IQR) of 0.60 (0.40-2.10) μg/L compared to a median (IQR) of 39.80 (25.00-56.40) μg/L observed in infants exclusively fed with formula. When we analyzed the change in urine elements concentrations between 3 and 18 months of age, we observed increased As (0.75 vs. 18.60μg/L), Co (0.05 vs. 0.24μg/L), Mo (1.98 vs. 50.0μg/L), Pb (0.15 vs. 0.69μg/L), Se (11.3 vs. 23.1μg/L), Tl (0.02 vs. 0.11μg/L), and V (0.05 vs. 0.11μg/L). For Cu, lower urine concentrations were observed at 18 months of age in comparison with concentrations at 3 months (5.77 vs. 4.41μg/L). Among the main food items identified as driving the changes in urine concentration between 3 and 18 months of age were white fish, rice and pasta, potato chips, custard, small blue fish, and legumes. Exclusively breastfed infants showed lower exposure to non-essential elements compared to those who were fed with a mixture or formula. With the introduction of solid foods, the exposure to some non-essential elements increased drastically, as in the case of As and Pb. In addition, exposure to the essential metal Mo also increased substantially with the introduction of solid food.

Factors Associated with Weaning in Infants with Cow's Milk Allergy: A Cohort Study.

Objective: To analyze the factors associated with weaning in infants with cow's milk allergy (CMA) treated at a food allergy reference center in a state in the northeast of Brazil. Method: A prospective cohort study, with a case group (children with CMA) and two control groups (symptomatic nonallergic children [SC] and asymptomatic [AC]). At the beginning of the study, 30 children comprised the CMA group, 84 the SC group, and 52 the AC group. Survival analysis was performed to compare breastfeeding time between the three groups and an adjusted linear regression model to verify the factors associated with breastfeeding time. Results: At the beginning of the study, 33.3% of children in the CMA group, 17.1% in the SC group, and 69.6% in the AC group were exclusively breastfeeding (p = 0.005). The most common factors for weaning in children with CMA were the cow's milk elimination diet (30%), allergic symptoms in the child (20%), and breast engorgement (20%). Children who used a cup as a means of offering infant formula spent 281 more days breastfeeding compared with those who used a baby bottle (Bstd = 1.39; p = 0.031). Conclusion: Children with CMA and nonallergic gastrointestinal complaints weaned earlier compared with asymptomatic children. The main causes of weaning in CMA children were maternal difficulty adhering to the elimination diet, breast engorgement, and allergic symptoms in the child. Using a cup was the main factor associated with longer breastfeeding duration, regardless of gastrointestinal symptoms and socioeconomic factors.

Factors of late respiratory support or oxygen weaning in infants with bronchopulmonary dysplasia.

Bronchopulmonary dysplasia (BPD) is the most common complication in preterm infants. This study aimed at identifying factors associated with early or with late or weaning failure from respiratory support or oxygen (O2) in preterm infants with BPD requiring respiratory support or O2 therapy after discharge from the neonatal intensive care unit (NICU). This retrospective study was conducted in the NICU of a tertiary hospital, in infants born before 32 weeks of gestation between 2012 and 2021, and discharged from the NICU with a respiratory support (tracheostomy [TT], invasive ventilation [IV], Non-IV [NIV], continuous positive airway pressure [CPAP], high flow nasal canula [HFNC]) or O2 therapy for BPD. Univariate and multivariate analyses were performed to identify factors associated with early weaning (before 6 months postmenstrual age [PMA]) or late (after 6 months PMA) and weaning failure. Among the 53 infants included (2% TT, 2% IV, 11% NIV, 25% CPAP or HFNC, 60% O2 at NICU discharge), 23 (43%) were weaned from respiratory support or O2 before 6 months PMA and 39 (73%) before 12 months PMA. IV duration during NICU stay and postnatal steroid treatment were identified as factors associated with a late or weaning failure (OR 1.03, p = .04 and OR 4.11, p = .023, respectively). In this study, nearly half of preterm infants with severe BPD were weaned from respiratory support or O2 before 6 months PMA. IV duration and postnatal steroid treatment during NICU stay were associated with a late or weaning failure.

Allergens weaning: what is missing from commercial baby food?

Background. Current recommendations for infant weaning suggest introducing common food allergens by the age of 12 months. While homemade meals are advisable, there is a notable demand for commercially available complementary foods (CACF). Furthermore, emerging evidence suggests a potential link between the consumption of ultra-processed products and the incidence of allergic diseases. This study aimed to examine the presence of the fourteen main food allergens in CACF ingredients through label analysis and evaluate their extent of processing. Methods. Between January and February 2024, labels of all CACF found in infant feeding sections of 10 Portuguese grocery retailers were analyzed. CACF were categorized based on the NOVA food classification system's processing levels. Milk formulas, products for children over 15 months, and those for children with food allergies or intolerances were excluded Results. Of the 492 products analysed, 132 contained wheat and 112 contained milk. 16 products included fish and 6 contained egg. Soy was listed as an ingredient in 11 products, mainly as soy lecithin. Only 2 product contained nuts, and 1 product contained peanuts. None of the products contained the remaining six allergens. The majority of milk- and wheat-containing products were classified as ultra-processed and contained added sugars and/or sweeteners. Conclusions. Despite the current guidelines, commercial baby foods often lack major allergens, namely nuts and peanuts, eggs, and shellfish. Our results underscore the need for healthy, age-appropriate, minimally processed products that incorporate rather than exclude major food allergens.

Food-breastmilk combinations alter the colonic microbiome of weaning infants: an in silico study.

The introduction of solid foods to infants, also known as weaning, is a critical point for the development of the complex microbial community inhabiting the human colon, impacting host physiology in infancy and later in life. This research investigated in silico the impact of food-breastmilk combinations on growth and metabolite production by colonic microbes of New Zealand weaning infants using the metagenome-scale metabolic model named Microbial Community. Eighty-nine foods were individually combined with breastmilk, and the 12 combinations with the strongest influence on the microbial production of short-chain fatty acids (SCFAs) and branched-chain fatty acids (BCFAs) were identified. Fiber-rich and polyphenol-rich foods, like pumpkin and blackcurrant, resulted in the greatest increase in predicted fluxes of total SCFAs and individual fluxes of propionate and acetate when combined, respectively, with breastmilk. Identified foods were further combined with other foods and breastmilk, resulting in 66 multiple food-breastmilk combinations. These combinations altered in silico the impact of individual foods on the microbial production of SCFAs and BCFAs, suggesting that the interaction between the dietary compounds composing a meal is the key factor influencing colonic microbes. Blackcurrant combined with other foods and breastmilk promoted the greatest increase in the production of acetate and total SCFAs, while pork combined with other foods and breastmilk decreased the production of total BCFAs.IMPORTANCELittle is known about the influence of complementary foods on the colonic microbiome of weaning infants. Traditional in vitro and in vivo microbiome methods are limited by their resource-consuming concerns. Modeling approaches represent a promising complementary tool to provide insights into the behavior of microbial communities. This study evaluated how foods combined with other foods and human milk affect the production of short-chain fatty acids and branched-chain fatty acids by colonic microbes of weaning infants using a rapid and inexpensive in silico approach. Foods and food combinations identified here are candidates for future experimental investigations, helping to fill a crucial knowledge gap in infant nutrition.

Theophylline impact on weaning in oxygen-dependent infants followed in an outpatient Kangaroo Program.

Theophylline was an orally administered xanthine used for treatment of apnea of prematurity and Bronchopulmonary Dysplasia in ambulatory follow-up of Low-Birth-Weight infants (LBWI) with oxygen-dependency in the outpatient Kangaroo Mother Care Program (KMCP). Theophylline's main metabolic product is caffeine; therefore, it was an alternative due to the frequent lack of ambulatory oral caffeine in low and middle-income countries. To assess the effectiveness of oral theophylline in decreasing days with oxygen and to describe frequency of adverse related events. Quasi-experiment before and after withdrawal of theophylline given systematically to LBWI with ambulatory oxygen in two KMCPs. 729 patients were recruited; period 1: 319 infants when theophylline was given routinely and period 2: 410 infants when theophylline was no longer used. The theophylline cohort had less gestational age, less weight at birth, more days in Neonatal Intensive Care Unit, more days of oxygen-dependency at KMCP admission, and more frequencies of Intrauterine Growth Restriction and apneas. After adjusting with propensity score matching, multiple linear regression showed that nutrition was associated with days of oxygen-dependency, but theophylline treatment not. No differences were found in frequencies of readmissions up to 40 weeks, intraventricular hemorrhage or neurodevelopmental problems. Participants in period 2 had more tachycardia episodes. We did not find association between oral theophylline treatment and the reduction of days with ambulatory oxygen. For the current management of oxygen-dependency in LBW infants, the importance of nutrition based on exclusive breast feeding whenever possible, is the challenge.

Evaluating Pressure Variability and Influencing Factors during High-Flow Nasal Cannula Therapy in Premature Infants.

Heated humidified high-flow nasal cannulas (HHHFNCs) are increasingly used as an alternative strategy for weaning from nasal continuous positive airway pressure (NCPAP) in premature infants. However, the optimal pressure provided by HHHFNCs is unknown. This retrospective study investigated the pressure changes and associated factors during HHHFNC therapy in preterm infants. Clinically stable preterm neonates born with a birth weight of 2500 g or less and receiving HHHFNC therapy for weaning from NCPAP were enrolled. The flow of the HHHNFCs was adjusted to achieve an initial pressure equivalent to the positive expiratory pressure (PEEP) of NCPAP. Subsequent pressure changes in the HHHFNCs were measured by a GiO digital pressure gauge. Nine premature infants were enrolled. Their gestational age (mean ± SD) was 28.33 ± 2.61 weeks, and the birth weight was 1102.00 ± 327.53 g. Overall, 437 pressure measurements were conducted. The median pressure of the HHHFNCs was 5 cmH2O. The generated pressure had a significant association with the body weight, postmenstrual age (PMA) and flow rate. A multiple regression model revealed that the measured pressure (cmH2O) = -5.769 + 1.021 × flow rate (L/min) - 0.797 × body weight (kg) + 0.035 × PMA (days) (r2 = 0.37, p < 0.001). The pressure provided by HHHFNCs is influenced by body weight, PMA, and flow rate. It is feasible to set the delivered pressure of HHHFNCs to match the applied PEEP of NCPAP initially, facilitating the weaning of preterm infants from NCPAP to HHHFNCs.

Trends and practices of weaning in infants across India: A comprehensive review.

Weaning is a critical phase in an infant's life, during which there is a transition from exclusive breastfeeding or formula feeding to consuming solid foods. Weaning is a critical step in determining a child's nutritional status, growth, and general health. India is a multiethnic and culturally diverse nation and has a variety of weaning practices that are affected by local customs, religious beliefs, and socioeconomic concerns. Malnutrition brought on by inadequate weaning methods used in infancy and early childhood may have an impact on cognitive, motor and social, development and productivity of the child, more importantly manifesting in later ages. Weaning customs in India have a long history of being ingrained in both family and cultural traditions. The variety of Indian cuisine is reflected in the meals that are offered to the infant during weaning. Homemade food commonly prepared like mashed fruits and vegetables, lentil soups, and rice porridge are the most popular. However, the inclination by parents toward professionally produced infant foods and formulas has increased because of urbanization and globalization; there have been observable changes in weaning practices over the past few decades because of changing lifestyles and easier access. These foods are frequently thought of as more convenient but may not be as nutrient-dense as homemade alternatives. Not following the medically recommended mandate of an exclusive diet of mother's breast milk to the infant, many parents often begin introducing complementary foods as early as four months. Still most concerningly also the timing of weaning commencement varies significantly across areas and communities. Overall, this review offers valuable insights into the current trends and practices of weaning in infants across India, underscoring the importance of culturally sensitive and informed strategies to ensure the well-being of the nation's youngest population.

Effects of Nutrition Education Program on Lactating Mothers in Relation to Infant Feeding Practices

Maternal and child health status is profoundly affected by infant feeding practices. In Pakistan, these practices are sub optimal which may lead to adverse outcomes. The initiation of breastfeeding within the first hour of birth, as well as good counseling of lactating mothers regarding infant weaning and introduction of complementary foods to the infants in a hygienic and clean environment, can decrease the risk of malnutrition and infections, leading to a decrease in infant morbidity and mortality. Increasing the awareness of mothers regarding recommended feeding practices is a key to improving this situation, especially in the region of South Asia. The current study was conducted with the aim of assessing the impacts of contextually developed nutrition education sessions on the knowledge and attitudes of women regarding infant feeding. A quasi experiment was conducted for this purpose. A sample of 400 lactating mothers between 20-30 years of age visiting a private post-natal clinic located in Lahore, Pakistan was selected. Half of the sample (200) was included in the experimental group and exposed to 12 weeks of educational intervention based on various audio-visual aids. Pretest and posttest knowledge and attitude scores of the women of both control and experimental groups were recorded. The results showed that women belonging to both control and experimental groups had similar knowledge regarding infant feeding at baseline (pretest). However, experimental group showed significant improvement in knowledge scores after intervention, as compared to control. The results also revealed that simple educational intervention can lead to profound improvements in maternal knowledge and attitudes regarding infant feeding. Increasing awareness is the first step in the translation of knowledge into practice. Therefore, similar interventions may be helpful in improving infant breast and complementary feeding practices. Effective implementation of nutrition education interventions that can improve the breastfeeding rates and also bring about improvement in complementary feeding practices is important for a developing country like Pakistan. This, in turn, may lead to better health outcomes for infants by reducing direct and indirect impacts of undernutrition.

Long-term continuous cultivation of Kenyan infant fecal microbiota using the host adapted PolyFermS model

Appropriate in vitro models to investigate the impact of novel nutritional strategies on the gut microbiota of infants living in rural Africa are scarce. Here, we aimed to develop such a continuous gut fermentation model based on the PolyFermS platform, which allows controlled and stable long-term cultivation of colon microbiota in conditions akin the host. Nine immobilized Kenyan infant fecal microbiota were used as inoculum for continuous PolyFermS colon models fed with medium mimicking the weaning infant diet. Fructo-oligosaccharides (FOS) supplementation (1, 4 and 8 g/L) and cultivation pH (5.8 and 6.3) were investigated stepwise. Conditions providing a close match between fecal and in vitro microbiota (pH 5.8 with 1 g/L FOS) were selected for investigating long-term stability of four Kenyan infant PolyFermS microbiota. The shared fraction of top bacterial genera between fecal and in vitro microbiota was high (74–89%) and stable during 107 days of continuous cultivation. Community diversity was maintained and two distinct fermentation metabolite profiles of infant fecal microbiota were observed. Three propiogenic and one butyrogenic metabolite profile of infant fecal microbiota established from day 8 onwards and stayed stable. We present here the first rationally designed continuous cultivation model of African infant gut microbiota. This model will be important to assess the effect of dietary or environmental factors on the gut microbiota of African infants with high enteropathogen exposure.

Bifidobacterium longum subsp. iuvenis subsp. nov., a novel subspecies isolated from the faeces of weaning infants.

The species Bifidobacterium longum currently comprises four subspecies: B. longum subsp. longum , B. longum subsp. infantis , B. longum subsp. suis and B. longum subsp. suillum . Recently, several studies on B. longum suggested the presence of a separate clade containing four strains isolated from infants and one from rhesus macaque. These strains shared a phylogenetic similarity to B. longum subsp. suis DSM 20210T and B. longum subsp. suillum JCM1995T [average nucleotide identity (ANI) of 98.1 %) while showed an ANI of 96.5 % with both B. longum subsp. infantis and B. longum subsp. longum . The current work describes five novel additional B. longum strains isolated from Bangladeshi weaning infants and demonstrates their common phylogenetic origin with those of the previously proposed separated clade. Based on polyphasic taxonomic approach comprising loci multilocus sequence analysis and whole genome multilocus sequence typing, all ten examined strains have been confirmed as a distinct lineage within the species B. longum with B. longum subsp. suis and B. longum subsp. suillum as closest subspecies. Interestingly, these strains are present in weaning infants and primates as opposed to their closest relatives which have been typically isolated from pig and calves. These strains, similarly to B. longum subsp. infantis , show a common capacity to metabolize the human milk oligosaccharide 3-fucosyllactose. Moreover, they harbour a riboflavin synthesis operon, which differentiate them from their closest subspecies, B. longum subsp. suis and B. longum subsp. suillum . Based on the consistent results from genotypical, ecological and phenotypical analyses, a novel subspecies with the name Bifidobacterium longum subsp. iuvenis, with type strain NCC 5000T (=LMG 32752T=CCOS 2034T), is proposed.

Accuracy of lung and diaphragm ultrasound in predicting infant weaning outcomes: a systematic review and meta-analysis.

Although lung and diaphragm ultrasound are valuable tools for predicting weaning results in adults with MV, their relevance in children is debatable. The goal of this meta-analysis was to determine the predictive value of lung and diaphragm ultrasound in newborn weaning outcomes. For eligible studies, the databases MEDLINE, Web of Science, Cochrane Library, PubMed, and Embase were thoroughly searched. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) method was used to evaluate the study's quality. Results were gathered for sensitivity, specificity, diagnostic odds ratio (DOR), and the area under the curve of summary receiver operating characteristic curves (AUSROC). To investigate the causes of heterogeneity, subgroup analyses and meta-regression were conducted. A total of 11 studies were suitable for inclusion in the meta-analysis, which included 828 patients. The pooled sensitivity and specificity of lung ultrasound (LUS) were 0.88 (95%CI, 0.85-0.90) and 0.81 (95%CI, 0.75-0.87), respectively. The DOR for diaphragmatic excursion (DE) is 13.17 (95%CI, 5.65-30.71). The AUSROC for diaphragm thickening fraction (DTF) is 0.86 (95%CI, 0.82-0.89). The most sensitive and specific method is LUS. The DE and DTF were the key areas where study heterogeneity was evident. Lung ultrasonography is an extremely accurate method for predicting weaning results in MV infants. DTF outperforms DE in terms of diaphragm ultrasound predictive power.

Comparative Screening of the Nutritive Composition and Serum Nutrient Levels of Rats Weaned with Rice (Oryza spp) - Beniseed (Sesame indicum) Flour Blends

Weaning foods should complement the nourishment the baby receives from milk. This study was carried out to evaluate the nutritional value of Rice-Beniseed (R-B) flour-blends in rats’ pups. The objective of the study was to determine the Nutritive value of Rice-Beniseed flour blends of rats’ pups weaned with different ratios of the flour-blends. First, mature female and male rats in the ratio of 2:1 were mated to produce pups used in the analyses. The pups were randomly distributed into five groups of five rats and were fed with the experimental (Rice-Beniseed) blends. Group 1 was fed with a standard weaning meal, groups 2, 3, 4 and 5 were fed ad lib with Rice-Beniseed blends (after proximate analysis for nutritive content) in the ratio of 30:70, 50:50, 60:40 and 70:30 respectively. All treatments lasted for 21 days, after which their blood was collected for haematological and biochemical analyses. The results showed carbohydrate (71.76 %) and moisture content (14.75 %) of rice to be higher than beniseed with values of 18.74 and 8.24 % respectively. The crude proteins (23.19 %), crude fibre (11.47 %) and fats (36.40%) content in beniseed was more than doubled compared to that in rice with 9.38 %, 1.339 % and 2.41 % for crude protein, crude fibre, and fats contents respectively. Percentage weight change in pups was highest (26.31 ± 1.03%) and least (8.69 ± 2,32%) in the 50:50 and 60:40 rice-beniseed groups on day 7. Percentage weight change of pups on day 14 showed that groups fed with 70:30 and 50:50 ratios with the highest (37.24 ± 0.47%) and least (6.16 ± 1.14%) weight gain respectively. Hence, 70:30 (Rice-Beniseed blend) meal produced the best growth index (weight increase) and was potentially viable for the formulation of infant weaning formula amidst appreciable performance of all other ratios.

The Association of Tube Weaning and Oral Skill Development in Infants With Tube Dependency: A Prospective Study.

This study was the first of its kind by assessing oral skills development during and after applying the "Graz Model" of tube weaning. This prospective case series study included data of 67 (35 females, 32 males, treated from March 2018 to April 2019) tube dependent children, who participated in the effective "Graz Model" of tube weaning. Parents filled out the standardized Pediatric Assessment Scale for Severe Feeding Problems (PASSFP) prior to and immediately after completion of the program. Paired sample t tests were conducted to examine pre-to-post changes in the children's oral skills. The study showed that oral skills increased significantly during tube weaning PASSFP score of 24.76 (standard deviation, SD = 12.38) prior to versus 47.97 (SD = 6.98) after completion of the program. Furthermore, significant changes in their sensory and tactile perception and in their general eating behavior were observed. Children also showed reduced oral aversion symptoms and food pocketing, could enjoy their meals, and increased their food repertoire. Mealtime duration could be decreased, and parents were less anxious about their infants' intake and less frustrated because of their children's eating behavior. The results of this study demonstrated for the first time that tube dependent children can improve their oral skills significantly during and after their participation in the child-led approach of the "Graz model" of tube weaning.

Recommendations regarding weaning in infants &amp; its importance in oral health status

Aim: To evaluate the knowledge, attitude and practice regarding weaning in infants among dental professionals in Gujarat. Materials and Methods: A cross-sectional survey was conducted among IDA members of Gujarat. Self- prepared questionnaire was validated by Subject Experts. The electronic questionnaire was sent to the participants through e-mail. Data was collected and analyzed using the SPSS software with significant value p&lt;0.05. Results:Only 33% of respondents were aware that bottle unavailability completely represented weaning cessation. 56% considered that weaning should start at 6-8 months of age however 44% of them considered at 12-15 months of age. 63% considered that weaning should be achieved by the age of 12-18 months. Weaning recommendations vary among various dental professionals. Conclusion: Dentists frequently lack a common understanding of newborn weaning guidelines. To create good and reliable oral health preventive recommendations for parents and caregivers, dentists must reach a clear consensus. As a result, dental practitioners need to have a thorough education, and these subjects need to be included in the basic education system. Keywords: Weaning, Infants, Knowledge, Awareness, Dentists

Early Medieval English Life Courses: Cultural-Historical Perspectives ed. by Thijs Porck and Harriet Soper

Reviewed by: Early Medieval English Life Courses: Cultural-Historical Perspectives ed. by Thijs Porck and Harriet Soper Timothy D. Arner thijs porck and harriet soper, eds., Early Medieval English Life Courses: Cultural-Historical Perspectives. Leiden: Brill, 2022. Pp. xii, 369. isbn: 978–90–04–49929–4. $194. Early Medieval English Life Courses: Cultural-Historical Perspectives literally considers some age-old questions: how does the human body change throughout its lifetime? What is the relationship between physical, emotional, and intellectual maturity? How is the biological process of aging conditioned by one’s social environment? The essays in this volume look for answers in a range of sources from pre-Conquest England, and, in so doing, provide a rich account of perspectives on the stages of human development. The collection helpfully groups the essays into four sections with three essays in each. Part I is dedicated to ‘Defining and Dividing the Life Course,’ with the first two essays examining how stages of the human life course were classified in early medieval English texts. Thijs Porck’s ‘The Ages of Man and the Ages of Woman in Early Medieval England: From Bede to Byrhtferth of Ramsey and the Tractatus de quaternario’ describes different approaches to categorizing life stages in Old English [End Page 102] and Anglo-Norman manuscripts. Tracing aging schemata as represented through three key works, Porck demonstrates that ‘early medieval English authors stuck to a flexible but uniform definition of the human life course’ (p. 45), and he identifies a significant shift in this paradigm during the twelfth century. Daria Izdebska’s essay surveys vocabulary for describing the stages of life throughout the Old English corpus, linking the various words used to describe infancy, youth, maturity, and old age to their Latin equivalents and to the Old English lexemes associated with these phases. These essays are followed by a discussion of an individual’s particular and influential understanding of aging and maturity, as Darren Barber’s ‘Alcuin and the Student Life Cycle’ highlights Alcuin’s writings about how one’s development through the stages of youth allows greater possibilities for moral and spiritual education. The second set of essays on ‘The Life Course and the Human Body’ considers the discourse around significant bodily changes or events. Jacqueline Fay’s ‘Treating Age in Medical Texts from Early Medieval England’ offers the field’s first look at ‘how, or even if, Old English medieval remedies are inflected by age’ (p. 118) and how these texts define normative and non-normative bodies with regard to age, gender, and bodily strength. Caroline R. Batten examines Old English obstetric remedies, demonstrating how the pregnant female body is more consistently associated with death than the creation and nurturing of life. In ‘The Theology of Puberty in Early Medieval England,’ Elaine Flowers shows how ‘the biological process of puberty in pre-Conquest England . . . generated theological consequences associated with leaving an age of spiritual innocence behind’ (p. 160). Focusing almost exclusively on the male body as a pubescent subject, theological discourse describes sexual temptation as both a challenge and opportunity for young men to demonstrate moral understanding and self-control. The essays in ‘Part III: Intergenerational Dynamics’ concern how names, knowledge, and goods are passed down to create a sense of individual identity within a community. James Chetwood’s essay on naming and renaming demonstrates how names were bestowed not only at birth but throughout one’s life to signal familial and social bonds. Just as Flowers’ essay in Part II considers the theological discourse regarding bodily processes, Katherine Cross examines how eighth- and ninth-century ecclesiastical texts refer to the weaning of infants as both a natural life process and a metaphor for spiritual instruction. Amy Faulkner’s essay on treasure describes how Genesis A presents an ideal model for aristocratic inheritance that Beowulf shows to be prone to disruption. The volume’s final section considers ‘Life Beyond the Human.’ Gale R. Owen-Crocker demonstrates how object biography can reveal ‘The Life Course of Artefacts’ as she examines the Orkney Hood, the Bayeux Tapestry, the Sutton Hoo Hanging Bowl and Shield, and early English manuscripts. The final essay places the linear life course of human development alongside the...

Nutritional evaluation of formulated Arachis hypogea L. and Anacardium occidentale L. supplemented feeds in weaning albino rats

Malnutrition is still a serious public health problem in developing countries including Nigeria. This may be attributed to the deficiency of vital nutrients, especially in weaning foods for infants. The current study evaluated the nutritional importance of two formulations: Arachis hypogea and Anarcardium occidentale supplemented feeds in weaning rats. The proximate composition analysis of the formulated Arachis hypogea and Anarcardium supplemented feeds contained significantly (P&lt;0.05) high amounts of carbohydrates, lipids and proteins. There were also significantly (P&lt;0.05) high levels of amino acids; lysine, arginine, methionine, histidine, leucine, tryptophan and phenylalanine, compared to the control. A total of 15 weaned albino rats were used in the experiment. The animals were divided into three groups; A, B and C. Group A was fed with standard feed while Groups B and C were fed with Arachis hypogea and Anarcardium occidentale supplemented feeds respectively, for 21 days, after which the blood samples were collected for biochemical and hematological assays using standard methods. The level of glucose, total proteins, albumin and globulin were significantly higher (P&lt;0.05) compared to the control. The results of hematological parameters indicated significantly (P&lt;0.05) increased packed cell volume (PCV), red blood cells (RBC), hemoglobin (HB) and platelets (PLT), when compared to the control. These results indicated the nutritional significance of the two formulated feeds for complementation in weaning foods and infants’ nutrition.

STUDY OF INFANT WEANING PRACTICES IN A TERTIARY CARE HOSPITAL

Background: Complementary feeding is extremely essential from six months of age, while continuing breastfeeding, to meet the nutritional demands of the growing baby. Hence this study was intended to determine various factors inuencing weaning in infants. Objectives: 1. To study weaning practices in infants of age between six to twelve months. To know the status of nutrition of the child in relation to weaning practices and socio-demographic prole. 2. To know the age of weaning and its impact on a child's growth. Materials and methods: Data was collected using a self-administered, semi-structured questionnaire with the mothers regarding practices of weaning.200 mothers were interviewed with infants, 6-12 months of age attending OPD in Narayana medical college and hospital, Nellore, Andhra Pradesh. Participants: Mothers with infants of age 6 months to 12 months who were attending OPD for minor illness or immunisation. Results: Among 200 mothers, practices of weaning were evaluated. seven months is the average age of weaning. Only a small number of health professionals had accurate information. 40% of mothers started on processed foods. Weaning is more likely to occur later in female children, mothers who lack literacy, people from lower socioeconomic status. There is no relationship between parity, occupation and residence(p&gt;0.05). Children that were underweight, stunted, or wasted made up 46.7%, 43.4%, and 36.6% of the population. There is a strong correlation between a child's malnutrition and delayed weaning. Conclusions: Most of the mothers were unaware of current standards regarding weaning time. Due to incorrect knowledge, wrong ideas and attitudes, illiteracy, low socioeconomic position, the average age of weaning is delayed, which causes the infant to become malnourished. Therefore, in order to prevent malnutrition and enhance the health of the children, proper information and education about timely weaning, weaning foods, preparation, and practices should be provided to mothers and caregivers

Diet Diversification and Priming with Kunu: An Indigenous Probiotic Cereal-Based Non-Alcoholic Beverage in Nigeria

Kunu is a fermented non-alcoholic beverage consumed all over Nigeria. The drink is served as an alternative to alcohol due to its perceived extreme nourishing and therapeutic properties. Varieties of this beverage are determined mostly by the type of grain, the supplements, sensory additives used, and the process employed during its production. Dietary quality is paramount in nutritional well-being and a key factor in human overall health development. The nutritional quality of grains utilised for Kunu production makes the drink more appealing to a large growing population when compared to some other drinks. Some use Kunu drink as an infant weaning drink, thus serving as a priming beverage for infants due to its rich probiotic and nutritional properties. However, this beverage’s short shelf-life has limited its production scale. This review therefore elaborates succinctly on the diverse therapeutic nutritional properties of the Kunu beverage and the effect of additives and fermentation on the microbial dynamics during Kunu production, as well as the prospect of Kunu in diet diversification and priming for weaning infants.

Infant egg consumption during introduction to solid food remains low in the United Kingdom but increases with infant age and a baby-led weaning approach.

As a nutritious food-providing protein, essential fatty acids, vitamin D, iodine and choline eggs have historically been central to an infant weaning diet. However, food poisoning scares and allergy concerns have contributed to low consumption among infants aged 6-12 months. This paper presents a secondary data analysis of infant egg exposure and intake using three weaning data sets: a 7-day food frequency questionnaire (n = 297), a 24-h recall (n = 180) and a 3-day weighed food diary (n = 71). Egg introduction, frequency of consumption and intake in grams were analysed for infants aged 6-8, 9-10 and 11-12 months). Comparisons were made by whether infants were following a baby-led approach to weaning (where infants self-feed family foods) or a traditional approach where pureed foods are given alongside finger foods. Data were collected in the United Kingdom between 2015 and 2018. Our data showed that despite introduction being recommended from the start of weaning at 6 months of age by the Department of Health, just 54% of infants aged 6-8 months had ever been offered eggs. Average egg intake was one to two times per week, increasing with age. However, in terms of frequency and grams consumed, our data suggest a small increase in consumption compared with previous research, although limitations of our smaller sample size should be noted. Finally, a baby-led approach was associated with increased exposure and consumption; baby-led infants consumed eggs twice as frequently as spoon-fed infants. The findings have important implications for public health messaging and for supporting families in introducing solid foods.
