Concerns for anaphylaxis may hamper severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunization efforts. We convened a multidisciplinary group of international experts in anaphylaxis composed of allergy, infectious disease, emergency medicine, and front-line clinicians to systematically develop recommendations regarding SARS-CoV-2 vaccine immediate allergic reactions. Medline, EMBASE, Web of Science, the World Health Organizstion (WHO) global coronavirus database, and the gray literature (inception, March 19, 2021) were systematically searched. Paired reviewers independently selected studies addressing anaphylaxis after SARS-CoV-2 vaccination, polyethylene glycol (PEG) and polysorbate allergy, and accuracy of allergy testing for SARS-CoV-2 vaccine allergy. Random effects models synthesized the data to inform recommendations based on the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) approach, agreed upon using a modified Delphi panel. The incidence of SARS-CoV-2 vaccine anaphylaxis is 7.91 cases per million (n [ 41,000,000 vaccinations; 95% confidence interval [95% CI] 4.02-15.59; 26 studies, moderate certainty), the incidence of 0.15 cases per million patient-years (95% CI 0.11-0.2), and the
The term planetary health—denoting the interdependence between human health and place at all scales—emerged from the environmental and preventive health movements of the 1970–80s; in 1980, Friends of the Earth expanded the World Health Organization definition of health, stating: “health is a state of complete physical, mental, social and ecological well-being and not merely the absence of disease—personal health involvesplanetary health”. Planetary health is not a new discipline; it is an extension of a concept understood by our ancestors, and remains the vocation of multiple disciplines. Planetary health, inseparably bonded to human health, is formally defined by the inVIVO Planetary Health network as the interdependent vitality of all natural and anthropogenic ecosystems (social, political and otherwise). Here, we provide the historical background and philosophies that have guided the network, and summarize the major themes that emerged at the 7th inVIVO meeting in Canmore, Alberta, Canada. We also provide the Canmore Declaration, a Statement of Principles for Planetary Health. This consensus statement, framed by representative participants, expands upon the 1986 Ottawa Charter for Health Promotion and affirms the urgent need to consider the health of people, places and the planet as indistinguishable.
Human milk provides essential substrates for the optimal growth and development of a breastfed infant. Besides providing nutrients to the infant, human milk also contains metabolites which form an intricate system between maternal lifestyle, such as the mother’s diet and the gut microbiome, and infant outcomes. This study investigates the variation of these human milk metabolites from five different countries. Human milk samples (n = 109) were collected one month postpartum from Australia, Japan, the USA, Norway, and South Africa and were analyzed by nuclear magnetic resonance. The partial least squares discriminant analysis (PLS-DA) showed separation between either maternal countries of origin or ethnicities. Variation between countries in concentration of metabolites, such as 2-oxoglutarate, creatine, and glutamine, in human milk, between countries, could provide insights into problems, such as mastitis and/or impaired functions of the mammary glands. Several important markers of milk production, such as lactose, betaine, creatine, glutamate, and glutamine, showed good correlation between each metabolite. This work highlights the importance of milk metabolites with respect to maternal lifestyle and the environment, and also provides the framework for future breastfeeding and microbiome studies in a global context.
This open-label, non-randomized, multicenter trial (Registration: NCT 03661736) aimed to assess if an amino acid-based formula (AAF) supplemented with two human milk oligosaccharides (HMO) supports normal growth and is well tolerated in infants with a cow’s milk protein allergy (CMPA). Term infants aged 1–8 months with moderate-to-severe CMPA were enrolled. The study formula was an AAF supplemented with 2′-fucosyllactose (2′-FL) and lacto-N-neotetraose (LNnT). Infants were fed the study formula for 4 months and were offered to remain on the formula until 12 months of age. Tolerance and safety were assessed throughout the trial. Out of 32 infants (mean age 18.6 weeks; 20 (62.5%) male), 29 completed the trial. During the 4-month principal study period, the mean weight-for-age Z score (WAZ) increased from −0.31 at the baseline to +0.28 at the 4-months’ follow-up. Linear and head growth also progressed along the WHO child growth reference, with a similar small upward trend. The formula was well tolerated and had an excellent safety profile. When comparing the microbiome at the baseline to the subsequent visits, there was a significant on-treatment enrichment in HMO-utilizing bifidobacteria, which was associated with a significant increase in fecal short-chain fatty acids. In addition, we observed a significant reduction in the abundance of fecal Proteobacteria, suggesting that the HMO-supplemented study formula partially corrected the gut microbial dysbiosis in infants with CMPA.
Background: Excessive use of specialized formula for cow's milk allergy was reported in England, but complete analysis has not been undertaken and trends in other countries are unknown. Some specialized formula products, especially amino-acid formula (AAF), have high free sugars content. We evaluated specialized formula trends in countries with public databases documenting national prescription rates.Methods: Cross-sectional analysis of national prescription databases in the United Kingdom, Norway and Australia. Outcomes were volume and cost of specialized formula, and proportion of infants prescribed specialized formula. Expected volumes assumed 1% cow's milk allergy incidence and similar formula feeding rates between infants with and without milk allergy.Results: Prescribed volumes of specialized formula for infants rose 2.8-fold in England from 2007 to 2018, with similar trends in other regions of the United Kingdom.Volumes rose 2.2-fold in Norway from 2009 to 2020 and 3.2-fold in Australia from 2001 to 2012. In 2020, total volumes were 9.7-to 12.6-fold greater than expected in England, 8.3-to 15.6-fold greater than expected in Norway and 3.3-to 4.5-fold greater than expected in Australia, where prescribing restrictions were introduced in 2012. In Norway, the proportion of infants prescribed specialized formula increased from 2.2% in 2009 to 6.9% in 2020, or 11.2-to 13.3-fold greater than expected. In 2020, specialized formula for infants cost US$117 (103 euro) per birth in England, US$93 (82 euro) in Norway and US$27 (23 euro) in Australia. Soya formula prescriptions exceeded expected volumes 5.5-to 6.4-fold in England in 1994 and subsequently declined, coincident with public health concerns regarding soya formula safety. In 2020, 30%-50% of prescribed specialized formula across the three countries was AAF.
Conclusions:In England, Norway and Australia, specialized formula prescriptions increased in the early 21st century and exceeded expected levels. Unnecessary specialized formula use may make a significant contribution to free sugars consumption in young children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
