Infant consumption of 100% lactose-based and reduced lactose infant formula in the United States: Review of NHANES data from 1999 to 2020.

OBJECTIVES: An acceptable alternative to human milk is US Food and Drug Administration (US FDA)-registered infant formula, which must meet the requirements of the US FDA Infant Formula Act. Human milk contains lactose, but some infant formulas may contain alternative carbohydrate sources such as corn syrup solids, maltodextrin, and sucrose. Recent research shows that infant-formula made with corn syrup solids may be associated with increased obesity risk in the first 5 years of life. A previous study found that of all formulas purchased, 59.0% were lactose-reduced. More US infants consume infant formula with nonlactose carbohydrates more frequently than is medically necessary. The purpose of this study is to use National Health and Nutrition Examination Survey (NHANES) data to describe the type and prevalence of nonlactose carbohydrates consumed in infant formula. METHODS: NHANES data from 1999 to 2020 was used to perform cross-sectional analyses and analyses of comparison of prevalence over time on consumption of nonlactose carbohydrate sources in infant formulas. RESULTS: We identified 3709 unique infant IDs associated with 36,084 feeding sessions. More than half of the feeding sessions involved a formula with at least one nonlactose carbohydrate. Feeding sessions involving a formula with at least one nonlactose carbohydrate increased by 163% from 1999-2004 to 2017-2020; formulas containing single or multiple nonlactose carbohydrate types account for the increase in prevalence. CONCLUSIONS: This study highlights an increase in the consumption of infant formula containing a nonlactose carbohydrate. More studies are needed to understand the short- and long-term effects of early exposure to these carbohydrates.

Cross-Sectional Analysis of Infant Diet, Outcomes, Consumer Behavior and Parental Perspectives to Optimize Infant Feeding in Response to the 2022 U.S. Infant Formula Shortage.

In May of 2022, millions of U.S. parents encountered uncertainty in safely feeding their infants due to the infant formula shortage. METHODS: An anonymous, electronic, cross-sectional, retrospective survey was used. RESULTS: U.S. parents (n = 178) whose infants were ~10 weeks old during the shortage completed the survey. Of parents, 81% switched formulas during the shortage, 87% switched because they could not find the formula they typically used, 34% switched 3-5 times, 29% of parents visited ≥4 stores/24 h and 26% of parents traveled >20 miles/24 h to purchase formula. Use of infant formula increased (p < 0.01); in infants requiring specialty formula, use of intact cow's milk formula increased (p < 0.05) and use of premature infant formulas decreased (p < 0.05). Infants relying on specialty formulas experienced at least one undesirable outcome compared with non-specialty users. Parents used social media, relatives/friends and healthcare providers for support during the shortage, but their helpfulness scores were suboptimal. Parents reported the need for greater infant formula availability, free prenatal lactation education and postpartum lactation support. CONCLUSIONS: Government, regulatory and healthcare policy oversight are needed to protect the infant feeding system, including more commercially available products, access to banked donor milk and lactation support.

Nutrition Content of Young Child Formulas.

OBJECTIVE: European Society for Pediatric Gastroenterology, Hepatology and Nutrition and the American Academy of Pediatrics state that young child formula (YCF) is not considered necessary for healthy children. Despite these recommendations, YCF accounts for approximately 13% of overall formula sales. Five percent of infants less than 1 year of age in the United States are being fed YCF. The purpose of this study is to identify the most Internet recommended and encountered YCF in the United States and determine if they meet nutritional recommendations for use in children 0-3 years. STUDY DESIGN: We used the search terms "toddler formula," "toddler milk," "follow-up formula," or "young child formula" in Google and DuckDuckGo to identify the most like encountered or recommended YCF on the Internet. We compared their labeled nutrients to Food and Drug Administration (FDA) Infant Formula Act (IFA) and international nutrient recommendations, given the absence of US nutrient requirements for YCF recommendations, for children 12-36 months. RESULTS: Twenty-nine YCF were reviewed. On average, YCF did not meet nutrient recommendations for infants and toddlers with 2.17 and 4.6 ingredients not meeting formula recommendations for younger and older infants, respectively, and between 3 and 4 ingredients for 12-36 months. CONCLUSIONS: Nutrition content of YCF are variable and do not meet FDA IFA requirements or YCF international recommendations. Increased US regulation is needed for YCF. It is important for health care providers to ask patients what they are feeding their infants and toddlers so they can educate parents on potential nutritional safety concerns.

The Impact of eConsults on Access to Specialty Care for the Uninsured in Rural Texas.

OBJECTIVE: This study evaluated the impact of eConsults on access to specialty care for uninsured patients in Central Texas. METHODS: eConsults for four specialties, cardiology, gastroenterology, rheumatology, and endocrinology, were implemented in a large, multi-site federally qualified health center. Data were collected on specialty care access and utilization for a one-year period before and after implementation of the new process. RESULTS: Prior to implementation, 23% of uninsured patients referred to the included specialties completed a visit with a specialist. After implementation, 62% received a specialty consultation either through an eConsult or with a face-to-face visit. Wait times for referrals improved from a median of 54 days to seven days. CONCLUSION: This project demonstrated that eConsults improve access and reduce wait times for specialty care for uninsured patients. Interventions such as this have the potential to reduce health inequalities by providing timely access to care for common specialty concerns.

Nutritional and Safety Concerns of Infant Feeding Trends.

OBJECTIVE: The American Academy of Pediatrics (AAP) and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition recommend either exclusively breastfeeding for at least 6 months or an u.S. Food and Drug Administration-reviewed infant formula or donor breast milk from an established milk bank as alternatives. The purpose of this study was to establish the prevalence of contemporary infant feeding practices such as informal human milk sharing, imported European infant formula, toddler formula and homemade formula and gain insight into the parental reasoning for their choices. STUDY DESIGN: An anonymous, cross-sectional, voluntary electronic survey was sent to active prescribers to a Yumi (a baby food subscription company) list server in April and May 2021. Basic demographic, utilization of infant feeding practices and general feeding practices were collected. RESULTS: Of 2315 respondents, at least 18% of the families were following at least one contemporary feeding practice. Thirty six percent of parents using donor breast milk obtained it from unregulated sources, 14% of the respondents were using European infant formula, 5% were using toddler formula for their infants, and 2% were making homemade infant formula. CONCLUSION: The AAP has clear guidelines on infant nutrition and breastfeeding and when not possible, FDA reviewed infant formula or donor breast milk from an established milk bank as alternatives. Yet, our study found that at least 18% of the families across the united States were following at least one contemporary feeding practice with possible nutritional and safety concerns. it is important for pediatric gastroenterologists and dieticians to ask their patients how they are feeding their infants and be aware of these feeding practices that may pose significant health risks.

Offering preimplantation genetic testing for monogenic disorders (PGT-M) for conditions with reduced penetrance or variants of uncertain significance: Ethical insight from U.S. laboratory genetic counselors.

Preimplantation genetic testing for monogenic disorders (PGT-M) was originally developed to identify embryos affected with serious childhood-onset disorders, but its use has recently broadened. Guidance on the use of PGT-M in the United States (U.S.) is currently limited, with no formal laws or guidelines established on its use. The goals of this study were to determine for which types of conditions U.S. laboratories currently do not offer PGT-M, to explore ethical considerations U.S. laboratory genetic counselors (GCs) take into consideration when deciding to accept or reject a PGT-M request, and to explore whether U.S. laboratory GCs believe PGT-M should be offered for conditions with reduced penetrance or for variants of uncertain significance (VUS). Qualitative analysis of semi-structured interviews with nine genetic counselors, from five different PGT-M laboratories, was conducted. Participants were required to be GCs working at a PGT-M laboratory in the U.S. and either actively counsel patients on PGT-M or determine a patient's eligibility for PGT-M. Two participants reported their separate laboratories have no limitations for allowable PGT-M testing, while the other seven participants representing three other laboratories reported having limitations. The main ethical consideration GCs reported considering when deciding to accept or reject a PGT-M request was patient autonomy, with a focus on the patient understanding risks of the testing. All participants reported believing PGT-M should be allowable for conditions with reduced penetrance and VUS, with all participants stating their respective laboratories allow for this currently. However, all participants reported a lack of sufficient guidelines and that having guidelines from a professional organization would be beneficial to their practice. In conclusion, lack of current guidelines in the United States has created discrepancies between PGT-M laboratories. PGT-M laboratory GCs support the use of PGT-M for conditions with reduced penetrance and VUS with informed consent. The need for guidelines is supported.

Disparities in Telehealth Utilization Within Pediatric Gastroenterology: One Academic Center's Experience.

OBJECTIVES: While the use of telemedicine has accelerated significantly with the recent pandemic, it has also magnified disparities in access to telemedicine. This study aims to look at telemedicine utilization patterns within a large pediatric gastroenterology practice. METHODS: A retrospective study of ambulatory care visits within Yale-New Haven Hospital's pediatric gastroenterology practice during the peak expansion of the telemedicine program was conducted. Zip code-level socioeconomic data were obtained using the Distressed Communities Index. A multivariate logistic regression to evaluate disparities between the use of video versus telephone visits was computed, and unadjusted and adjusted odds ratios with 95% confidence intervals (CIs) were obtained. RESULTS: A total of 1273 clinic visits were included in analysis. The majority of the patients listed English as their preferred language, had private insurance, and identified as non-Hispanic White. When adjusting for co-variates, having public insurance/Medicaid was associated with decreased odds of having video over telephone visits (adjusted odds ratio [aOR] 0.60; 95% CI 0.44-0.80). Those whose primary language was not English continued to have a statistically significant decreased odds of using video visits (Spanish aOR 0.24; 95% CI 0.13-0.44; other aOR 0.29; 95% CI 0.12-0.72). Within the adjusted multivariate logistic regression, race/ethnicity and SES were, however, no longer found to have a statistically significant decreased odds of video visits. CONCLUSIONS: The accelerated implementation of telemedicine within pediatric gastroenterology has given rise to disparities in its use. Further studies are needed to understand these disparities and develop interventions to lessen this gap in usage.

Impact of Pediatric Electronic Consultations in a Federally Qualified Health Center.

Background: Access to pediatric specialty care is a challenge, particularly for medically underserved populations. Introduction: One evolving method that has shown promise in helping ameliorate this disparity is electronic consultations (e-consults). Materials and Methods: This retrospective cohort study compared two groups: patients referred to pediatric cardiology, endocrinology, or pulmonology from a Federally-Qualified Health Center 10 months before the implementation of an evidence-based care pathway and those referred in the 10 months after implementation. The care pathway included evidence-based referral guidelines for common pediatric diagnoses and an e-consult process. Data included patient demographics, dates of referral requests, appointment dates, e-consult response dates and times, diagnosis codes, and consultants' recommendations. Results: Twenty-three percent of all referrals made postimplementation were submitted for an e-consult, with 53% preventing an unnecessary face-to-face visit. The most common reason for an e-consult was heart murmur/chest pain for cardiology, short stature for endocrinology, and asthma for pulmonology. Discussion: Providers used e-consults for nearly one-quarter of all consultations postimplementation, resulting in 17% of consultations not needing a face-to-face visit. The use of e-consults combined with evidence-based referral guidelines provided a useful tool to help front line pediatric primary care providers manage complex problems and identify those not needing to see a specialist in person. Conclusions: Evidence-based care pathways combined with e-consults can help improve access to pediatric specialty care by reducing demand for in-person visits and allowing more care to be delivered in primary care.

Assessment of Community Pediatric Providers' Approach to Children With Helicobacter pylori.

In 2016, the European and North American Societies for Pediatric Gastroenterology, Hepatology, and Nutrition updated guidelines for management of Helicobacter pylori in children, adjusting the previous diagnostic and therapeutic approaches in response to changing epidemiology and antibiotic resistance patterns. In this study, we assessed knowledge, practice habits of H. pylori management, and adherence to new guideline recommendations among one state's community pediatric providers. The majority of the surveyed community pediatric providers are not following the new pediatric guidelines for H. pylori management. An evidence-practice gap for diagnosis and treatment of H. pylori disease can lead to poor resource utilization, inadequate antibiotic usage, increased antibiotic resistance, and prolonged symptoms in patients. By understanding pediatric provider practices, pediatric gastroenterologists can assist in addressing the gap through development of educational interventions for community pediatric providers.

Non-FDA-Reviewed Imported European Formula Use Among Parents in Urban Pediatric Private Practice.

In 2018, the American Academy of Pediatrics warned consumers over the increasing use of imported infant formulas. The purpose of this study was to assess the usage of imported European infant formula among parents in a large urban private practice. An anonymous survey was distributed at well-child appointments to a convenience sample of parents at an urban private pediatric practice from November 2017 to March 2018. Of the 750 eligible respondents, 552 (74%) completed the survey. Of the parents using formula, 20% were using imported European infant formulas. The most commonly used formula was Holle (33%), and 72% were acquired from web-based third-party vendors. Parents chose to use these formulas because they believed that European formulas contained better ingredients. Only 8% of parents received information about European infant formula from their pediatricians. Pediatricians need to be aware of these formulas and their risks to educate families on the use and safety of these formulas.

Impact of Endocrinology eConsults on Access to Endocrinology Care for Medicaid Patients.

Background: Access to endocrinologists is a particular challenge for medically underserved populations. Introduction: Electronic consultations (eConsults) are a promising tool to help address this problem. Materials and Methods: This retrospective cohort study compared two groups: (1) Medicaid patients referred to an endocrinologist 1 year before the implementation of eConsults and (2) those referred in the 1 year after implementation. Data included patient demographics, dates of referral requests, appointment dates, eConsult response dates and times, diagnosis codes, and consultants' recommendations. Provider perspectives of eConsults were determined by using a survey. Results: Before eConsult implementation, only 138 out of 365 (37.8%) of referrals to endocrinology were completed. Postimplementation, 281 out of 469 (59.9%) of referrals were completed either by a confirmed face-to-face visit with an endocrinologist or by an eConsult, of whom 194 (41.4%) did not require a face-to-face visit. Thyroid conditions were the most common reason for a consult, accounting for roughly 40% of all consults. Overall, 32 out of 36 (89%) primary care providers (PCPs) indicated that they were satisfied with eConsults and 19 out of 36 (53%) felt that the process did not create additional work or burden for them. Discussion: These findings demonstrate that eConsult use can help address poor access to specialty care for Medicaid-insured patients. eConsults were able to significantly decrease the need for face-to-face visits and enabled PCPs to address specialty-related issues in primary care. Conclusions: Widespread adoption of eConsults could be a potential solution for major challenges that our health care system faces today.

IgA-deficient humans exhibit gut microbiota dysbiosis despite secretion of compensatory IgM.

Immunoglobulin A is the dominant antibody isotype found in mucosal secretions and enforces host-microbiota symbiosis in mice, yet selective IgA-deficiency (sIgAd) in humans is often described as asymptomatic. Here, we determined the effects of IgA deficiency on human gut microbiota composition and evaluated the possibility that mucosal secretion of IgM can compensate for a lack of secretory IgA. We used 16S rRNA gene sequencing and bacterial cell sorting to evaluate gut microbiota composition and taxa-specific antibody coating of the gut microbiota in 15 sIgAd subjects and matched controls. Despite the secretion of compensatory IgM into the gut lumen, sIgAd subjects displayed an altered gut microbiota composition as compared to healthy controls. These alterations were characterized by a trend towards decreased overall microbial diversity as well as significant shifts in the relative abundances of specific microbial taxa. While secretory IgA in healthy controls targeted a defined subset of the microbiota via high-level coating, compensatory IgM in sIgAd subjects showed less specificity than IgA and bound a broader subset of the microbiota. We conclude that IgA plays a critical and non-redundant role in controlling gut microbiota composition in humans and that secretory IgA has evolved to maintain a diverse and stable gut microbial community.

Comparison of Imported European and US Infant Formulas: Labeling, Nutrient and Safety Concerns.

OBJECTIVE: Infant formula in the United States is highly regulated. The American Academy of Pediatrics (AAP) has reported concerns over the use of non-Food and Drug Administration (FDA)-registered imported infant formulas. The purpose of this study is to identify Internet purchased and recommended imported European infant formulas and compare them with FDA labeling and nutrient requirements. STUDY DESIGN: We searched "European infant formulas" in Google and DuckDuckGo to identify vendors of European formulas and blogs discussing these formulas to determine the most frequently purchased and recommended brands. We then compared the identified European formula's label and listed nutrients to FDA labeling and nutrient requirements. RESULTS: Thirteen of 18 vendors responded to our inquiry of their top selling formula and 17 blogs were reviewed. Sixteen formulas were identified. None met all FDA label requirements. Listed nutrients fell within FDA requirements in 15 of 16 formulas. CONCLUSIONS: Non-FDA-registered imported European formulas do not meet all FDA-labeling requirements. Although linoleic acid, which was not listed on all of the European formulas, could not be evaluated, all formulas except one met the remaining FDA nutrient requirements. These European infant formulas are being imported into the United States via third party vendors and are not FDA-regulated, limiting the notable consumer protections set by the FDA that ensure infant formula safety. Pediatric gastroenterologists and healthcare providers need to understand the composition, labelling and lack of FDA regulation and safety concerns of these formulas in order to better counsel parents.

Segmentation of Both Diseased and Healthy Skin From Clinical Photographs in a Primary Care Setting.

This work presents the first segmentation study of both diseased and healthy skin in standard camera photographs from a clinical environment. Challenges arise from varied lighting conditions, skin types, backgrounds, and pathological states. For study, 400 clinical photographs (with skin segmentation masks) representing various pathological states of skin are retrospectively collected from a primary care network. 100 images are used for training and fine-tuning, and 300 are used for evaluation. This distribution between training and test partitions is chosen to reflect the difficulty in amassing large quantities of labeled data in this domain. A deep learning approach is used, and 3 public segmentation datasets of healthy skin are collected to study the potential benefits of pretraining. Two variants of U-Net are evaluated: U-Net and Dense Residual U-Net. We find that Dense Residual U-Nets have a 7.8% improvement in Jaccard, compared to classical U-Net architectures (0.55 vs. 0.51 Jaccard), for direct transfer, where fine-tuning data is not utilized. However, U-Net outperforms Dense Residual U-Net for both direct training (0.83 vs. 0.80) and fine-tuning (0.89 vs. 0.88). The stark performance improvement with fine-tuning compared to direct transfer and direct training emphasizes both the need for adequate representative data of diseased skin, and the utility of other publicly available data sources for this task.

Assessment of Community Pediatric Providers' Approach to a Child With Celiac Disease and Available Serological Testing Associated With a Large Tertiary Care Center.

An evidence-practice gap for use of celiac disease testing can lead to poor resource utilization. False positive tests may lead to unnecessary diet changes, gastroenterology consults, parental/patient concern, and additional testing and expenses complicated by varied available celiac bundles. An understanding of pediatric provider practices according to guideline recommendations further improves this gap.

Impact of dermatology eConsults on access to care and skin cancer screening in underserved populations: A model for teledermatology services in community health centers.

BACKGROUND: The clinical outcome of teledermatology with dermoscopy in large-scale primary care networks remains unclear. OBJECTIVE: We evaluate the impact of implementing a teledermatology consultation program with dermoscopy on a statewide scale, focusing on access to care and skin cancer screening for medically underserved populations. METHODS: Descriptive retrospective cohort study of 2385 dermatology referrals from primary care from June 2014 through November 2015. RESULTS: Before implementation of electronic consultations (eConsults), access to dermatology was limited; only 139 (11%) of 1258 referrals resulted in a confirmed appointment with a median wait time of 77 days. Post implementation, 499 of 1127 consults (44%) were sent electronically, and of those, 16% required a face-to-face visit with a median wait time of 28 days. Ten malignancies were identified via eConsults. Overall consult volume remained stable pre- and post-eConsult implementation. LIMITATIONS: We evaluated eConsults in medically underserved populations seeking care at community health centers. Results might not be generalizable to other populations or in other settings. CONCLUSION: eConsults increase access to dermatologic care and reduce wait times for patients receiving medical care at community health centers. Implementing dermoscopy into teledermatology could increase access to skin cancer screening and treatment for medically disadvantaged populations.

Creating a Program for Junior Faculty Professional Development: A Tool Kit.

Introduction: Junior academic faculty must balance increasing clinical responsibilities whilst maintaining academic portfolios aimed at promotion. Our goal was to design, implement, and evaluate a curriculum for career development amongst junior faculty in pediatrics. Methods: Following the Kern method of curriculum development, we performed a needs assessment of junior faculty via an electronic survey to identify areas for career development. We created objectives based on the themes identified and developed associated learning activities, including (1) a monthly seminar series, (2) an orientation day for new hires, and (3) a formal mentoring program for junior faculty. At the end of each academic year, we sent electronic surveys to junior faculty participants for program evaluation. Results: Of 50 junior faculty, 60% completed the initial needs assessment and identified a need for a forum for junior faculty orientation, career development, and formal mentoring. Local experts were solicited to create and lead a 10-part seminar series to cover topics such as CV review, promotions, and mentoring. Twenty-one junior faculty (42%) who did not already have established mentors joined the formal mentoring program. All incoming new junior faculty attended a formal orientation day held annually. At the end of the first year, a follow-up survey for program evaluation was completed by 17 (27%) junior faculty, and 98% reported satisfaction with the learning activities. Discussion: We successfully developed and implemented a junior faculty career development program at our institution that can be replicated at other institutions.

Reduced Cost Of Specialty Care Using Electronic Consultations For Medicaid Patients.

Specialty care accounts for a significant and growing portion of year-over-year Medicaid cost increases. Some referrals to specialists may be avoided and managed more efficiently by using electronic consultations (eConsults). In this study a large, multisite safety-net health center linked its primary care providers with specialists in dermatology, endocrinology, gastroenterology, and orthopedics via an eConsult platform. Many consults were managed without need for a face-to-face visit. Patients who had an eConsult had average specialty-related episode-of-care costs of $82 per patient per month less than those sent directly for a face-to-face visit. Expanding the use of eConsults for Medicaid patients and reimbursing the service could result in substantial savings while improving access to and timeliness of specialty care and strengthening primary care.
