RESUMO
Background: Few studies evaluate the effects of vitamin D status and supplementation on maternal bone mineral density (BMD) during lactation and further lack inclusion of diverse racial/ethnic groups, body mass index (BMI), or physical activity. Objective: Determine the effects of vitamin D treatment/status, feeding type, BMI, race/ethnicity, and physical activity on postpartum women's BMD to 7 months. Methods: Women with singleton pregnancies beginning 4-6 weeks' postpartum were randomized into two treatment groups (400 or 6400 IU vitamin D/day). Participant hip, spine, femoral neck, and whole-body BMD using Dual-energy X-ray absorptiometry (DXA Hologic), serum 25-hydroxyvitamin D [25(OH)D] (RIA; Diasorin), BMI, and physical activity were measured at 1, 4, and 7 months postpartum. A general linear mixed modeling approach was undertaken to assess the effects of vitamin D status [both serum 25(OH)D concentrations and treatment groups], feeding type, race/ethnicity, BMI, and physical activity on BMD in postpartum women. Results: During the 6-month study period, lactating women had 1-3% BMD loss in all regions compared with 1-3% gain in nonlactating women. Higher maternal BMI was associated with less bone loss in femoral neck and hip regions. Black American women had less BMD loss than White/Caucasian or Hispanic lactating women in spine and hip regions. Exclusively breastfeeding women in the 6400 IU vitamin D group had less femoral neck BMD loss than the 400 IU group at 4 months sustained to 7 months. Physical activity was associated with higher hip BMD. Conclusion: While there was BMD loss during lactation to 7 months, the loss rate was less than previously reported, with notable racial/ethnic variation. Breastfeeding was associated with loss in BMD compared with formula-feeding women who gained BMD. Higher BMI and physical activity independently appeared to protect hip BMD, whereas higher vitamin D supplementation appeared protective against femoral neck BMD loss.

BACKGROUND: Virtual care may improve access to healthcare and may be well suited to digitally connected youth, but experts caution that privacy and technology barriers could perpetuate access inequities. Success of virtual care will depend on its alignment with patient preferences. However, information on preferences for virtual and in-person healthcare is missing, especially for youth. We sought to quantify preferences for and barriers to virtual versus in-person mental and physical healthcare in youth and their parents, including in vulnerable segments of the population such as families with a parent with severe mental illness (SMI). METHODS: Participants were 219 youth and 326 parents from the Families Overcoming Risks and Building Opportunities for Wellbeing cohort from Canada, of which 61% of youth had at least one parent with SMI. Participants were interviewed about healthcare preferences and access to privacy/technology between October 2021 and December 2022. RESULTS: Overall, youth reported a preference for in-person mental (66.6%) and physical healthcare (74.7%) versus virtual care or no preference, and to a somewhat lesser degree, so did their parents (48.0% and 53.9%). Half of participants reported privacy/technology barriers to virtual care, with privacy being the most common barrier. Preferences and barriers varied as a function of parent SMI status, socioeconomic status and rural residence. CONCLUSIONS: The majority of youth and parents in this study prefer in-person healthcare, and the preference is stronger in youth and in vulnerable segments of the population. Lack of privacy may be a greater barrier to virtual care than access to technology.

BACKGROUND: Cross-sectional studies report high levels of depressive symptoms during the COVID-19 pandemic, especially in youth and females. However, longitudinal research comparing depressive symptoms before and during the pandemic is lacking. Little is known about how the pandemic affected individuals with familial history of mental illness. The present study examines the impact of the pandemic on youth depressive symptoms, including offspring of parents with major mood and psychotic disorders. METHODS: Between March 2018 and February 2020, we measured depressive symptoms in 412 youth aged 5-25 years. We measured depressive symptoms again in 371 (90%) of these youth between April 2020 and May 2022. Two thirds (249) participants had a biological parent with a major mood or psychotic disorder. We tested the effect of the pandemic by comparing depression symptoms before and after March 2020. We examined age, sex, and family history as potential moderators. RESULTS: We found an overall small increase in youth depressive symptoms (b = 0.07, 95% CI -0.01 to 0.15, p = 0.062). This was driven by an increase in female youth without familial history of mental illness (b = 0.35, 95% CI 0.14 to 0.56, p = 0.001). There was no change in depressive symptoms among offspring of parents with mental illness or males. CONCLUSIONS: Our results provide reassurance about the wellbeing of children of parents with mental illness during a period of restricted access to resources outside the family. Rather than increasing symptoms in established risk groups, the pandemic led to a redistribution of depression burden towards segments of the youth population that were previously considered to be low-risk.

More than a decade ago, two faculty met at a conference. Each talked about how they were charged with leading global health education efforts at their institutions and longed to have an opportunity to share resources and learn from each other. After reaching out to a few other Midwestern colleagues and finding a date, the first Midwest Consortium of Global Child Health Educators meeting was held in Madison, WI. Now, after a dozen annual meetings, more than 30 articles, chapters, abstracts, and workshops, as well as the creating, piloting, and sharing of several widely used curricula in global health education, the founding consortium members share the practical steps for faculty looking to form similar regional consortia around shared interests. In this article, the authors provide a recipe for the successful formation of an academic consortium based on the lessons learned from their experience. [Pediatr Ann. 2023;52(9):e351-e356.].

The events of recent years have affected the landscape of global child health education (GCHE) in the United States. War, racism, forced displacement, and the coronavirus disease 2019 (COVID-19) pandemic had global repercussions that reached US GCHE. The aim of this article is to examine the effect of these events on the landscape of GCHE in the US. Key areas of GCHE have been reframed, reshaped, and accelerated by these events. Travel restrictions accelerated virtual learning opportunities. Core curriculum needed to be reconsidered to address antiracism, equity, and decolonization. Expansion of GCHE activities, including local-global electives, was needed to meet increased resident demand and help address local community needs. Inequities in international partnerships were further highlighted, requiring new approaches. Global research education and practices were also affected with a rapid expansion in virtual opportunities and further development of education in equitable research practices.

Background: Vitamin D (vitD) plays a major role in maintenance of bone mineral homeostasis. It is unknown if bone mineral content (BMC) and bone mineral density (BMD) differ between infants who receive direct vitD supplementation and those who receive vitD indirectly via their mother's breast milk, while she received a high dose of vitD. It is hypothesized that there would be no differences in BMC or BMD by treatment group. Design/Methods: Randomized, double-blind trial to compare BMD and BMC of infants who received direct vitD (400 IU vitD3/day) in addition to their mother receiving standard dosage (400 IU vitD3/day) versus infants whose mothers were their only source of vitD and were given high-dose supplementation (6,400 IU vitD3/day). Participants were exclusively breastfeeding mothers and their infant consuming only human milk. Infant BMC and BMD were measured by dual-energy X-ray absorptiometry (DXA) scans of the infant's total body using Hologic Discovery A Densitometer and analyzed using Hologic Infant software at 1, 4, and 7 months of age. Results: Infant BMC and BMD did not differ significantly at 1, 4, or 7 months of age between direct and indirect supplementation arms. The mean difference in BMC from 1 to 7 months was 1.624 and 1.464 g for the 400 and 6,400 IU groups, respectively, (p = 0.5); the mean difference in BMD over this same period was 0.042 and 0.032 g/cm2 for the 400 and 6,400 IU groups, respectively (p = 0.2). Although some differences among races were observed, this did not reflect changes in bone growth between the treatment arms. Conclusion: High-dose vitD supplementation of mothers during lactation provided an efficacious alternative to direct supplementation of infants, as evidenced by noninferior infant BMD and BMC. Clinical Trial Registration number: NCT00412074.

Background: To ensure the safety of higher dose vitamin D supplementation in pregnant and lactating mothers, and urinary calcium/creatinine (UCa/Cr) ratios, serum calcium, and serum 25(OH)D concentrations are closely monitored. To achieve optimal maternal and infant vitamin D status, while avoiding hypercalcemia, safety measures assessing vitD supplementation must be reliable. Whether or not this holds true for infants before 7 months of age, remains unknown. Objective: Analyze the association among UCa/Cr ratio, serum calcium, intact serum parathyroid hormone (iPTH), 25(OH)D, and 25(OH)D/iPTH ratio in infants to determine whether evidence supports the use of these parameters as valuable measures of hypervitaminosis D or toxicity in infants. Methods: A series of analyses were performed on the cohort of infants who participated in the National Institute of Child Health and Human Development lactation vitD supplementation trial to determine the association among UCa/Cr ratio, serum calcium, iPTH, 25(OH)D, and 25(OH)D/iPTH ratio. Results: Upon multivariate analysis, serum calcium was significantly associated with 25(OH)D (p = 0.0441), iPTH (p = 0.0017), and 25(OH)D/iPTH ratio (p = 0.0001). Infant UCa/Cr did not associate with 25(OH)D but did associate with iPTH (p = 0.0008) and 25(OH)D/iPTH ratio (p = 0.0001). The correlation between UCa/Cr and 25(OH)D/iPTH ratios was significantly stronger than the association between UCa/Cr ratio and iPTH. Serum calcium more strongly correlated with 25(OH)D/iPTH ratio versus 25(OH)D and iPTH. Conclusion: In this healthy cohort of infants 1 to 7 months old, UCa/Cr and serum calcium are more valid indicators of 25(OH)D/iPTH ratio than either 25(OH)D or iPTH alone. Moreover, serum calcium (and not UCa/Cr) is a valid indicator of infant total circulating 25(OH)D and should be measured if vitamin D toxicity is a concern.

Global health education is offered increasingly during residency training. The University of Minnesota has offered a global pediatrics track to residents since 2005. This study aimed to understand the impacts of a global pediatrics track on graduates' career choices, skills, and current engagement in global health. An electronic survey was sent to 110 track graduates in February to April 2020. Data were analyzed with descriptive statistics and paired t-tests. Content analysis of written comments was conducted. The response rate was 62% overall, varying by question. Overall, 75% of responding graduates reported global pediatrics track participation affected their career choices. Eighty-four percent recalled plans to work in global health after graduation and 64% of respondents reported working in global health abroad or at home at the time of the survey. Incorporation of public health and global research represented the greatest percentage change in career plans from the time of enrollment to graduation (24% and 27%, respectively). Ninety-five percent of respondents reported that track participation improved their ability to elicit information about cultural beliefs and practices, and 86% reported improvement in cost-conscious care. An increase in global health knowledge and skills was the most common category of impact cited by respondents. Neonatal resuscitation, bubble continuous positive airway pressure, and homemade spacers for metered-dose inhalers were the most used global health-adapted skills. Our study found that graduates of the global pediatrics track perceive their participation affected their knowledge, skills, and attitudes positively, with the potential to improve clinical care and promote health equity locally and globally.

Background: The safety of higher dose vitamin D (vitD) supplementation in women who change from exclusive or full breastfeeding to combination feeding or who continue supplementation after cessation of breastfeeding is unknown. Objective: Compare vitD supplementation safety of 6,400 to 400 IU/day and 2,400 IU/day using specific laboratory parameters in postpartum women and their infants through 7 months postpartum by feeding type. Design: In this randomized controlled trial, mothers (exclusively breastfeeding or formula-feeding) were randomized at 4-6 weeks' postpartum to 400, 2,400, or 6,400 IU vitD3 (cholecalciferol)/day for 6 months. Breastfeeding infants in 400 IU group received oral 400 IU vitD3/day; infants in 2,400 and 6,400 IU groups received placebo. Maternal safety parameters (serum vitD, 25-hydroxy-vitamin D [25(OH)D; calcidiol], calcium, phosphorus, intact PTH; urinary calcium/creatinine ratios; and feeding type/changes) were measured monthly; infant parameters were measured at months 1, 4, and 7. Sufficiency was defined as 25(OH)D >50 nmol/L. Feeding type was defined as exclusive/full, combination, or formula-feeding. Data were analyzed using SAS 9.4. Results: Four hundred nineteen mother-infant pairs were randomized into the three treatment groups and followed: 346 breastfeeding and 73 formula-feeding pairs. A dose of 6400 IU/day safely and significantly increased maternal vitD and 25(OH)D from baseline in all mothers regardless of feeding type (p < 0.0001) and was superior to the 400 and 2,400 IU groups in achieving vitD sufficiency with no other differences in safety parameters by treatment or feeding type. Infants in the 2,400 IU group were more likely vitD-deficient than the other groups; otherwise, there were no infant safety parameter differences. Conclusions: While 6,400 IU/day was more effective than 400 or 2,400 IU/day in achieving maternal vitD sufficiency in all feeding groups, the groups did not differ on other safety parameters. Similarly, infant safety parameters did not differ by treatment group or feeding status. Clinical Trial Registration: FDA IND Number: 66,346; ClinicalTrials.gov Number: NCT00412074.

Severe mental illness (SMI) refers to impairing and frequently chronic disorders that are difficult to treat. Lower cognitive performance early in life may be a manifestation of risk for SMI. Visual memory has been highlighted as a potential cognitive predictor of future risk of developing bipolar disorder and schizophrenia. We examined visual memory in 214 participants (mean age = 12.62, SD = 4.49) using the Rey Complex Figure Test (RCFT). Our sample included 37 offspring with no parental history of mental illness, 103 offspring with parental history of non-severe mental illness (NSMI), and 74 offspring with parental history of SMI. We tested the effects of family history of mental illness on visual memory using mixed-effects linear regression. After accounting for age, sex, and family clustering, we found that as severity of parental mental illness increases, offspring visual memory performance decreases significantly (b = -3.58, 95% CI -6.79 to -0.37, p = 0.029). We found that severity of parental mental illness predicts visual memory ability. This finding may help identify youth most at risk of developing mental illness and thus inform future interventions.
RESUMO
Activities may be modifiable factors that moderate the risk and resilience in the development of mental health and illness. Youth who spend more time using screens are more likely to have poor mental health. Conversely, time spent engaged in active behaviors (i.e., physical activity, socializing and reading) is associated with better mental health. The choice of activities may be important in offspring of parents with mental illness, who are at increased risk for developing mental disorders. Among 357 youth of the FORBOW (Families Overcoming Risks and Building Opportunities for Well-being) cohort aged 6-21, we examined whether parental diagnosis of mental illness (i.e., major depressive disorder, schizophrenia and bipolar disorder) and current levels of depression influenced the amount of time their offspring spent using screens and engaging in active behaviors. Parental history of mental illness and higher levels of current depression in mothers were associated with less time spent engaged in active behaviors and more time spent using screens. Creating opportunities and incentives for active behaviors may redress the balance between youth with and without a familial history of mental illness.

Residency programs are increasingly responding to the growing demand for global health (GH) education by forming dedicated GH tracks. These tracks incorporate a targeted curriculum, support best practices surrounding GH electives such as predeparture preparation and post-return debriefing, and encourage meaningful engagement with international and domestic partners. The University of Minnesota's pediatric residency has had a formal GH track since 2005, and although they have shared several curricular components in the literature, they have yet to provide a comprehensive summary of their GH track. In this article, the authors provide a thorough description of their evolving GH track model, highlighting outcomes and sharing free resources, with the goal of providing a concise, replicable GH track framework for educators seeking to provide more formal GH education within residency programs.

BACKGROUND: While resident participation in global health (GH) rotations has grown, little is known about trainee perceptions of the personal value of these international clinical experiences and their importance to the objectives of GH training. OBJECTIVE: We sought to better understand the clinical scenarios experienced during international rotations that residents perceived as most meaningful and the frequency of these experiences across scenarios and participating residents. METHODS: Using the conceptual framework of Schön's reflection on action, we asked University of Minnesota GH track pediatric and internal medicine-pediatric residents to describe 10 clinical scenarios they found interesting or impactful during their 2016-2017 GH elective. We conducted a qualitative analysis of the deidentified resident narratives and mapped themes to the Accreditation Council for Graduate Medical Education (ACGME) competencies. RESULTS: All eligible residents (n = 13) participated, yielding 129 unique clinical scenarios from 7 countries. We identified 5 thematic groups: (1) addressing challenges in making diagnoses in resource-limited settings; (2) dealing with patient outcomes different from those expected in the United States; (3) encountering and managing diseases in a different clinical context; (4) encountering and managing diseases in a different cultural context; and (5) reflecting on learning and self-growth. Of the 129 unique clinical scenarios, 30% (n = 39) had not been previously experienced by participants. Across the 5 themes, all ACGME core competencies were addressed. CONCLUSIONS: Residents identified meaningful scenarios of their GH experiences that are relevant to the educational and clinical objectives of GH training.
