RESUMEN
BACKGROUND: Inadequate breastfeeding and complementary feeding practices are key determinants of child malnutrition and impact one-third of the under-five mortality rate worldwide. The district of Namuno in Cabo Delgado (Mozambique) has been long registering a high prevalence of acute malnutrition. To date, no data exists about Infant and Young Child Feeding (IYCF) practices in the area. The current pilot study explores the feeding practices among children aged 0-23 months in Namuno and sets out its main drivers. METHODS: This cross-sectional study was realized between August and September 2019 and drew on questionnaires for mothers/caregivers of children aged 0 to 23 months. We computed IYCF indicators and correlated them with mothers'/caregivers' school attendance, delivery setting, and distance between home and the place where livelihood activities took place (workplace), using univariate and multivariate (age-adjusted) logistic regression analysis. RESULTS: The survey was data derived from a sample of 632 mothers/caregivers. 62% of 0-23-month-old children received colostrum whilst only 31% of 0-5 months babies were on exclusive breastfeeding (EBF). Among 6-23 months old children, 17% consumed foods and beverages from at least five out of eight defined food groups, 31% received a minimum frequency of meals, and 23% had a minimum acceptable diet. Data revealed a positive correlation between early initiation of breastfeeding and delivery in a maternity ward (OR 6.9, CI 3.2-16.1, p-value < 0.001). No difference in the IYCF indicators between female and male babies was detected. CONCLUSIONS: In the Namuno district, IYCF practices did not fulfill WHO/UNICEF's indicators and recommendations. This suggests that efforts should be focused on EBF-enabling interventions to improve children's dietary consumption patterns.

The pandemics of obesity, undernutrition, and climate change represent severe threats to child health. They co-occur; interact with each other to produce sequelae at biological, psychological, or social levels; and share common underlying drivers. In this paper, we review the key issues concerning child diet and nutritional status, focusing on the interactions with climate and food systems. Inadequate infant and young child feeding practices, food insecurity, poverty, and limited access to health services are the leading causes of malnutrition across generations. Food system industrialization and globalization lead to a double burden of malnutrition, whereby undernutrition (i.e., stunting, wasting, and deficiencies in micronutrients) coexists with overweight and obesity, as well as to harmful effects on climate. Climate change and the COVID-19 pandemic are worsening child malnutrition, impacting the main underlying causes (i.e., household food security, dietary diversity, nutrient quality, and access to maternal and child health), as well as the social, economic, and political factors determining food security and nutrition (livelihoods, income, infrastructure resources, and political context). Existing interventions have the potential to be further scaled-up to concurrently address undernutrition, overnutrition, and climate change by cross-cutting education, agriculture, food systems, and social safety nets. Several stakeholders must work co-operatively to improve global sustainable nutrition.

Adolescent health and well-being are of great concern worldwide, and adolescents encounter particular challenges, vulnerabilities and constraints. The dual challenges of adolescent parenthood and obesity are of public health relevance because of the life-altering health and socioeconomic effects on both the parents and the offspring. Prevention and treatment strategies at the individual and population levels have not been successful in the long term, suggesting that adolescent pregnancy and obesity cannot be managed by more of the same. Here, we view adolescent obese pregnancy through the lens of the social contract with youth. The disruption of this contract is faced by today's adolescents, with work, social and economic dilemmas which perpetuate socioeconomic and health inequities across generations. The lack of employment, education and social opportunities, together with obesogenic settings, increase vulnerability and exposure to lifelong health risks, affecting their offspring's life chances too. To break such vicious circles of disadvantage and achieve sustainable solutions in real-world settings, strong efforts on the part of policymakers, healthcare providers and the community must be oriented towards guaranteeing equity and healthy nutrition and environments for today's adolescents. The involvement of adolescents themselves in developing such programs is paramount, not only so that they feel a sense of agency but also to better meet their real life needs.

OBJECTIVES: The primary aim of this study was to compare the immunological profiles of children affected by recurrent acute otitis media (rAOM) with and without spontaneous tympanic membrane perforation (STMP). The secondary aim was to compare immunological features of children without parameters outside the normal range and affected by either rAOM or recurrent respiratory tract infections (rRTI). METHODS: In this study, otherwise healthy children (<10 years of age) with rAOM or rRTI were included. Data on perinatal history, vaccination status, presence of risk factors for rAOM or rRTI (including personal or family history of allergy) and number of infectious episodes in the previous 12 months were retrospectively obtained. Furthermore, data on immunological profile (blood cell count, circulating IgA, IgG, IgM and total IgE, IgG subclasses and lymphocyte subpopulations) were collected. The immune profile of children affected by rAOM with and without STMP were compared. Among children with parameters within normal range, we compared the levels of the immunological parameters of children affected by rAOM (with and without STMP) and rRTI. RESULTS: The study involved a total of 751 children: 566 (75.3%) with rAOM and 185 (24.7%) with rRTI. Among the 566 children with rAOM, 39.7% had uncomplicated rAOM and 60.3% had rAOM with STMP. The mean age of the study population was 34.9 (SD 20.5) months. The frequency of children with parameters outside the normal range was similar among children with rAOM with (4.9%) and without STMP (6.1%). Among subjects without parameters outside the normal range, children with uncomplicated rAOM had significantly lower serum IgG, lymphocyte CD8+ and CD19+ and significantly higher IgG2 levels than children affected by rAOM with STMP. Finally, children with rAOM had lower levels of IgA, IgM and IgG2 and higher levels of IgG, lymphocyte CD19+ and CD16/56+ compared to children with rRTI. CONCLUSIONS: A low (<6.5%) percentage of children with rAOM with or without STMP present parameters outside the normal range. Among subjects without parameters outside the normal range, children with uncomplicated rAOM have a different immune profile as compared to those with STMP and rRTI. New prospective studies are needed to further explore the immune features of children affected by rAOM with and without STMP.

Obese children are at high risk of developing vitamin D deficiency. Omega-3 polyunsaturated fatty acids and their derivatives might have a beneficial effect on vitamin D status of obese children, due to their anti-inflammatory action, and increasing its absorption. This multicenter, randomized, double-blind controlled study aims to investigate the effect of vitamin D and docosahexaenoic acid (DHA) co-supplementation for six months on vitamin D status, body composition, and metabolic markers of obese children with vitamin D deficiency. A total of 108 children were enrolled and 73 children completed the study: 33 were supplemented with an oral dose of 500 mg of DHA and 1200 IU/day of vitamin D3 and 41 were supplemented with 1200 IU/day of vitamin D3 + wheat germ oil. At the end of the study, more than 50% of the subjects improved their vitamin D status. However, co-supplementation was not more effective than vitamin D plus wheat germ oil. Fat mass percentage was significantly reduced, and body mass index improved in both groups, even if all the subjects were still obese at the end of the study. Children receiving both vitamin D and DHA presented a higher increase of DHA levels that could be relevant to prevent inflammatory-associated complications of obesity, but they had no effect on vitamin D levels.

Cancer vaccination is a powerful strategy to combat cancer. A very attractive approach to prime the immune system against cancer cells involves the use of tumor lysate as antigen source. The immunogenicity of tumor lysate can be further enhanced by treatment with hypochlorous acid. This study explores poly(lactic-co-glycolic acid) (PLGA) nanoparticles to enhance the delivery of oxidized tumor lysate to dendritic cells. Using human donor-derived dendritic cells, it is found that the use of PLGA nanoparticles enhances antigen uptake and dendritic cell maturation, as compared to the use of the free tumor lysate. The ability of the activated dendritic cells to stimulate autologous peripheral blood mononuclear cells (PBMCs) is assessed in vitro by coculturing PBMCs with A375 melanoma cells. Live cell imaging analysis of this experiment highlights the potential of nanoparticle-mediated dendritic-cell-based vaccination approaches. Finally, the efficacy of the PLGA nanoparticle formulation is evaluated in vivo in a therapeutic vaccination study using B16F10 tumor-bearing C57BL/6J mice. Animals that are challenged with the polymer nanoparticle-based oxidized tumor lysate formulation survive for up to 50 days, in contrast to a maximum of 41 days for the group that receives the corresponding free oxidized tumor lysate-based vaccine.

Peptides and proteins represent an emerging class of powerful therapeutics. Peptide and protein nanogels are attractive carriers for the transport and delivery of biologically active peptides and proteins because they allow essentially quantitative encapsulation of these biologics. One interesting field of use of peptide and protein nanogels is the transport of antigens and adjuvants in cancer immunotherapy. This study demonstrates the use of reduction-sensitive protein nanogels for the delivery of ovalbumin and oxidized tumor lysate-based antigens to mouse and human-donor-derived dendritic cells. Challenging mouse-derived and human dendritic cells with reduction-sensitive ovalbumin nanogels was found to significantly enhance antigen uptake as compared to the use of the corresponding free protein antigen. The experiments with mouse-derived dendritic cells further showed that the administration of ovalbumin in the form of reduction-sensitive nanogels enhanced dendritic cell maturation as well as the presentation of the SIINFEKL epitope as compared to experiments that use free ovalbumin. In addition to ovalbumin as a model antigen, the feasibility of reduction-sensitive nanogels was also demonstrated for the delivery of oxidized, whole tumor lysate-based cancer antigens. In experiments with dendritic cells harvested from human donors, dendritic cell uptake of the oxidized tumor lysate antigen was significantly enhanced in experiments that used oxidized tumor lysate nanogels as compared to the free antigen.

A 1-year pilot cross-sectional study was performed to assess eating behaviours and lifestyle among Chinese and Arab pregnant immigrants to Italy. A number of 95 Chinese and 83 Arab women were interviewed. Two ethnic-specific food frequency questionnaires were designed to reflect the habitual diet of women belonging to these ethnic groups. Food items frequency of consumption was discussed using healthy eating guidelines. In both populations, women met healthy eating guidelines, except for salt intake, which was double than recommended; meat, sweet products and sugar-sweetened beverages were consumed more frequently than recommended, while olive oil and yogurt were eaten less frequently. Chinese women did not reach the recommendations for dairy products and fatty fish and exceeded those for red and processed meat, whereas Arab women exceeded the recommendations for cheese. Our findings suggest that the Italian food environment did not significantly affect Chinese and Arab pregnant immigrants' diet.

Micronutrient deficiencies during pregnancy pose important challenges for public-health, given the potential adverse outcomes not only during pregnancy but across the life-course. Provision of iron-folic acid (IFA) supplements is the strategy most commonly practiced and recommended globally. How to successfully implement IFA and multiple micronutrient supplementation interventions among pregnant women and to achieve sustainable/permanent solutions to prenatal micronutrient deficiencies remain unresolved issues in many countries. This paper aims to analyse available experiences of prenatal IFA and multiple micronutrient interventions to distil learning for their effective planning and large-scale implementation. Relevant articles and programme-documentation were comprehensively identified from electronic databases, websites of major-agencies and through hand-searching of relevant documents. Retrieved documents were screened and potentially relevant reports were critically examined by the authors with the aim of identifying a set of case studies reflecting regional variation, a mix of implementation successes and failures, and a mix of programmes and large-scale experimental studies. Information on implementation, coverage, compliance, and impact was extracted from reports of large-scale interventions in Central America, Southeast Asia, South Asia, and Sub-Saharan Africa. The WHO/CDC Logic-Model for Micronutrient Interventions in Public Health was used as an organizing framework for analysing and presenting the evidence. Our findings suggest that to successfully implement supplementation interventions and achieve sustainable-permanent solutions efforts must focus on factors and processes related to quality, cost-effectiveness, coverage, utilization, demand, outcomes, impacts, and sustainability of programmes including strategic analysis, management, collaborations to pilot a project, and careful monitoring, midcourse corrections, supervision and logistical-support to gradually scaling it up.

OBJECTIVES: a description of the epidemiology of tuberculosis in the province of Prato (Tuscany Region, Central Italy) during the period 2007-2014 and verify the latency time between the onset of symptoms and the start of therapy. DESIGN: descriptive, observational study. SETTING AND PARTICIPANTS: tuberculosis cases were identified for the period 2007-2014 through an analysis of the notification files available at the Hygiene and Public Health Service of the Local Health Unit of Prato and through the Information System on Infectious Diseases database. RESULTS: in the years 2007-2014, 619 cases of tuberculosis were reported in the province of Prato, of which 465 (75.12%) were cases of pulmonary TB. The annual rate ranges from 35.2 cases per 100.00 inhabitants in 2010 to 18.5 cases per 100.000 inhabitants in 2012. The median age of foreign-born patients was significantly lower than the one of Italian-born subjects (34 years; interquartile range - IQR: 28-41 vs. 63 years; IQR: 45-77; <0.0001). The rate of cases in patients above 64 years and below 64 years was significantly different between Italian and foreign subjects (<0.01); this dissimilarity remained significant even after stratification by gender. Males were the most affected, in line with regional and national data. The average delay between the date of onset of symptoms and the initiation of therapy was 59 days (IQR: 28-104). CONCLUSIONS: tuberculosis is a complex disease both from an epidemiological and a clinical point of view. This complexity is more relevant in areas where different ethnic groups live together. The data presented in this paper show the necessity of an intervention to improve access to healthcare facilities through a deep collaboration among who works in public health, in general medicine, and in the multidisciplinary integrated care of the considered area.

BACKGROUND: Immunotherapy consists of activating the patient's immune system to fight cancer and has the great potential of preventing future relapses thanks to immunological memory. A great variety of strategies have emerged to harness the immune system against tumors, from the administration of immunomodulatory agents that activate immune cells, to therapeutic vaccines or infusion of previously activated cancer-specific T cells. However, despite great recent progress many difficulties still remain, which prevent the widespread use of immunotherapy. Some of these limitations include: systemic toxicity, weak immune cellular responses or persistence over time and most ultimately costly and time-consuming procedures. MAIN BODY: Synthetic and natural biomaterials hold great potential to address these hurdles providing biocompatible systems capable of targeted local delivery, co-delivery, and controlled and/or sustained release. In this review we discuss some of the bioengineered solutions and approaches developed so far and how biomaterials can be further implemented to help and shape the future of cancer immunotherapy. CONCLUSION: The bioengineering strategies here presented constitute a powerful toolkit to develop safe and successful novel cancer immunotherapies.

Pregnancy and infancy comprise the most critical stages for conditioning an individual's health, with a number of implications for subsequent risks of morbidity, mortality, and reproductive health. Nutrition may influence both the overall pregnancy outcome and the growth trajectory and immune system of the fetus and infant, with short- and long-term effects on the health of the offspring. Within this context, leading experts at Expo Milano 2015 in Milan, Italy, discussed up-to-date knowledge while providing suggestions and challenges before, during, and after pregnancy. This narrative review summarizes the key issues raised by the experts concerning the interplay between the nutritional environment from conception to early infancy and the offspring's immediate and lifelong health, with a particular focus on epigenetic mechanisms, probiotics, vitamin D, and breastfeeding. Taken together, the findings strengthen the awareness that nutritional exposures occurring from preconception to the postnatal period may be strong determinants of the offspring's health and may provide supportive evidence for current nutritional recommendations and guidelines for pregnant women and infants. Critical topics to be addressed in future research and translated into recommendations of public health relevance are also highlighted.

PURPOSE: Iron supplementation is associated with side effects and overload risk. We compared different regimens of iron supplementation on maternal hematological status and pregnancy outcome in a cohort of healthy pregnant women. MATERIALS AND METHODS: Eighty non-anemic women with a normal singleton pregnancy were recruited at 11-13 weeks and randomized into controls (C; n = 20) and groups supplemented with ferrous iron 30 mg (FI; n = 20), liposomal iron 14 mg (Sideral® Pharmanutra, Pisa PI, Italy) (LI14; n = 20) and liposomal iron 28 mg/daily (LI28; n = 20) up to 6 weeks post-partum. Longitudinal maternal blood samples for iron markers were collected. Data on birth outcome were recorded. The treatment effect was evaluated using a mixed-effect regression model. RESULTS: Both LI28 and LI14 groups showed significantly higher hemoglobin and ferritin concentrations compared with controls. Birth weight showed a trend to increase with supplementation, resulting in higher birth weight in the LI28 group compared with controls (3499 ± 464.1 g and 3092 ± 469.5 g, respectively, p < 0.01). CONCLUSIONS: Our data show the effectiveness of 28 mg and 14 mg LI on maternal anemia prevention, as previously reported with FI 40 mg. LI has similar effects of higher doses of ferrous iron on maternal hematological parameters, thus allowing to reduce iron doses and side effects.

Infants and toddlers have high nutritional requirements relative to body size but consume small amounts of food and therefore need nutrient-dense complementary foods. A cross-sectional study included children aged 6-24 months, stratified in three age categories (6-11 months, 12-17 months and 18-24 months) and randomly selected from an urban (n = 158) and a rural (n = 158) area, both of low socio-economic status, in the KwaZulu-Natal Province of South Africa. Dietary diversity and nutrient density of the complementary diet (excluding breast milk and formula milk) based on a repeated 24-h dietary recall was assessed. For breastfeeding children, nutrient density of the complementary diet was adequate for protein, vitamin A and vitamin C; and inadequate for 100% of children for zinc, for >80% of children for calcium, iron and niacin; and between 60% and 80% of children for vitamin B6 and riboflavin. Urban/rural differences in density for animal and plant protein, cholesterol and fibre occurred in 18-24-month-old children. Fewer than 25% of children consumed ≥4 food groups, with no urban/rural differences. Higher dietary diversity was associated with higher nutrient density for protein and several of the micronutrients including calcium, iron and zinc. The poor nutrient density for key micronutrients can probably be ascribed to lack of dietary variety, and little impact of mandatory fortification of maize meal/wheat flour on infants/toddlers' diet. Targeted strategies are needed to enable mothers to feed their children a more varied diet.

BACKGROUND: Small-quantity lipid-based nutritional supplements (SQ-LNS) may potentially be used for home fortification in poor settings, where low nutrient-dense complementary foods are commonly used for infant feeding. However, they need to be acceptable to succeed. OBJECTIVE: This study assessed the acceptability of 2 novel, SQ-LNS (A and B) for supplementing complementary foods among infants aged 6 to 12 months in a peri-urban South African community. METHODS: Both supplements were soy-based pastes and contained micronutrients and essential fatty acids. In addition, supplement B contained docosahexaenoic acid, arachidonic acid, phytase and l-lysine. Mother-infant pairs were enrolled in a 2-part trial. Part 1 (n = 16) was a test-feeding trial with a crossover randomized design, and a 5-point hedonic scale was used for sensory evaluation (disagree = 1, agree = 5). Part 2 (n = 38) was a 2-week, home-use trial followed by focus group discussions. RESULTS: In part 1, more than 70% of mothers reported a score ≥4 on sensory attributes for both SQ-LNSs indicating that both supplements were well perceived. In part 2, the mean reported consumption over the 2-week period was 65.3% ± 34.2% and 62.0% ± 31.3% of the 20 g daily portion for supplements A and B, respectively. Focus group discussions confirmed a positive attitude toward the supplements in the study population. CONCLUSION: This study showed acceptance of both SQ-LNSs in terms of sensory characteristics as well as in terms of practicality for home use.

This study evaluated the effects on satiety-related sensations of seven isoenergetic cereal-based breakfasts and two fruit products (salad and juice) consumed within breakfast or as a midmorning snack. Nine healthy women participated to 11 sessions following a randomized repeated-measures design. Subjects were asked to consume seven breakfasts consisting of a standard beverage and a different cereal-based product, and also fruit salad or apricot juice consumed within breakfast or as a midmorning snack. Satiety, desire-to-eat and perceived characteristics of products consumed were monitored on Visual Analog Scales from 8:30 am until lunch. Ratings registered and areas under the curve of sensations were analyzed by repeated-measures ANOVA. All breakfast meals maintained the satiety-related sensations at lunch time higher than basal values. The best satiety control was obtained when the fruit salad was consumed as a midmorning snack. Consequently, regular consumption of breakfast and of whole fruit as midmorning snack may be a valid strategy to achieve appetite control.
