Effect of Low-Dose Iron Supplementation on Early Development in Breastfed Infants: A Randomized Clinical Trial.

JAMA Pediatrics

Breastfed infants are at risk of iron deficiency, which is associated with suboptimal development. There is a paucity of evidence on the effects of iron supplementation on child development, and current guidelines are divergent.

To assess whether daily iron supplementation, 1 mg/kg, between 4 and 9 months in exclusively or predominantly breastfed infants improves psychomotor development at 12 months.

This was a randomized, double-blind, placebo-controlled trial conducted between December 2015 and May 2020 with follow-up through May 2023 in an outpatient setting in Poland and Sweden. Participants were healthy singleton infants born at term with birth weight greater than 2500 g who were exclusively or predominantly breastfed (>50%) and did not have anemia (hemoglobin >10.5 g/dL) at age 4 months. Exclusion criteria included major illness, congenital anomaly, food allergy, and difficulty communicating with caregivers.

Iron (micronized microencapsulated ferric pyrophosphate), 1 mg/kg, or placebo (maltodextrin) once daily from age 4 to 9 months.

The primary outcome was psychomotor development assessed by motor score of Bayley Scales of Infant and Toddler Development III at 12 months, adjusted for gestational age, sex, and maternal education. Secondary outcomes included cognitive and language scores at 12 months; motor, cognitive, and language scores at 24 and 36 months; iron deficiency (serum ferritin <12 ng/mL), and iron deficiency anemia (iron deficiency and hemoglobin <10.5 g/dL) at 12 months.

Of 221 randomized infants (111 female), 200 (90%) were included in the intention-to-treat analysis (mean [SD] age, 12.4 [0.8] months). Iron supplementation (n = 104) compared to placebo (n = 96) had no effect on psychomotor development (mean difference [MD] for motor score, -1.07 points; 95% CI, -4.69 to 2.55), cognitive score (MD, -1.14; 95% CI, -4.26 to 1.99), or language score (MD, 0.75; 95% CI, -2.31 to 3.82) at 12 months. There were no significant differences at 24 and 36 months. The intervention did not reduce the risk for iron deficiency (relative risk [RR], 0.46; 95% CI, 0.16 to 1.30) or iron deficiency anemia (RR, 0.78; 95% CI, 0.05 to 12.46) at 12 months.

No benefit was found with daily low-dose iron supplementation between 4 and 9 months with respect to psychomotor development, risk of iron deficiency, or iron deficiency anemia among breastfed infants in a setting of low risk of anemia.

US Immigration Policy Stressors and Latinx Youth Mental Health.

JAMA Pediatrics

The youth mental health crisis is exacerbated for Latinx adolescents, a group whose families are targets of anti-immigrant rhetoric and policy.

To investigate how immigration-related stressors are associated with disruptions in parent-child relationships and, in turn, the mental health symptoms of Latinx adolescents.

Data for this prospective cohort study of adolescent-mother dyads were derived from surveys completed at 3 time points spanning 4 years (time 1 [T1] in 2018, time 2 [T2] in 2020, and time 3 [T3] in 2022). Mediation analyses estimated paths from immigration-related stressors to parent-child relationship qualities to mental health symptoms from early to late adolescence. Multivariable and multivariate linear models within a structural equation modeling framework regressed mediators and outcome variables on their own T1 values, offering a scientifically rigorous test of mediation. The setting was a school district in suburban Atlanta, Georgia, and included Latinx adolescents (ages 11-16 years) randomly selected from grade and gender strata. Data were analyzed from June 2023 to March 2024.

The primary independent variables were T1 mother reports of anti-immigrant worry and behavioral modification and adolescent reports of family member detention or deportation. Mediating variables were the reports of parental support and parent-child conflict of T2 adolescents.

T3 adolescent reports of past 6-month internalizing and externalizing symptoms.

A total of 547 Latinx adolescents (mean [SD] age, 13.3 [1.0] years; 303 female [55.4%]; 244 male [44.6%]) were included in this study. Response rates were 65.2% (547 of 839) among contacted parents and 95.3% (547 of 574) among contacted adolescents with parental permission. Four-year retention rates were 67% (366 of 547 adolescents) and 65% (177 of 271 mothers). Structural model results showed that T1 anti-immigrant worry and behavioral modification was associated with T3 increases in externalizing symptoms indirectly through T1 to T2 increases in parent-child conflict (β = 0.03; SE = 0.02; 95% CI, 0-0.08). For girls, T1 family member deportation or detention was associated with T1 to T3 increases in internalizing and externalizing symptoms indirectly through T1 to T2 declines in parental support (internalizing: β = 0.04; SE = 0.02; 95% CI, 0-0.08; externalizing: β = 0.03; SE = 0.02; 95% CI, 0-0.07). Sensitivity analyses supported structural model findings.

Results of this cohort study suggest that legislative bodies, the health care system, and educational institutions should implement safeguards to mitigate potential harm conferred by anti-immigrant environments for parent-child relationships and, in turn, Latinx adolescents' mental health.

Identifying Population-Level and Within-Hospital Disparities in Surgical Care.

Journal of the

The lack of consensus on equity measurement and its incorporation into quality-assessment programs at the hospital and system levels may be a barrier to addressing disparities in surgical care. This study aimed to identify population-level and within-hospital differences in the quality of surgical care provision.

The analysis included 657 National Surgical Quality Improvement Program participating hospitals with over 4 million patients (2014-2018). Multi-level random slope, random intercept modeling was used to examine for population-level and in-hospital disparities. Disparities in surgical care by Area Deprivation Index (ADI), race, and ethnicity were analyzed for five measures: all-case inpatient mortality, all-case urgent readmission, all-case postoperative surgical site infection, colectomy mortality, and spine surgery complications.

Population-level disparities were identified across all measures by ADI, two measures for Black race (all-case readmissions and spine surgery complications), and none for Hispanic ethnicity. Disparities remained significant in the adjusted models. Prior to risk-adjustment, in all measures examined, within-hospital disparities were detected in: 25.8-99.8% of hospitals for ADI, 0-6.1% of hospitals for Black race, and 0-0.8% of hospitals for Hispanic ethnicity. Following risk-adjustment, in all measures examined, fewer than 1.1% of hospitals demonstrated disparities by ADI, race, or ethnicity.

Following risk adjustment, very few hospitals demonstrated significant disparities in care. Disparities were more frequently detected by ADI than by race and ethnicity. The lack of substantial in-hospital disparities may be due to the use of postoperative metrics, small sample sizes, the risk adjustment methodology, and healthcare segregation. Further work should examine surgical access and healthcare segregation.

Thirty- and 90-Day Morbidity and Mortality by Clavien-Dindo 30 and 90 Days after Surgery for Antireflux and Hiatal Hernia.

Journal of the

The historic morbidity and mortality rates of anti-reflux and hiatal hernia surgery are reported as 3-21% and 0.2-0.5%, respectively. These data come from either large national/population level or small institutional studies, with the former focusing on broad 30-day outcomes while lacking granular data on complications and their severity. Institutional studies tend to focus on long-term and quality of life outcomes. Our objective is to describe and evaluate the incidence of 30 and 90-day morbidity and mortality in a large, single institution dataset.

We retrospectively reviewed 2342 cases of anti-reflux and hiatal hernia surgery from 2003-2020 for intra-operative complications causing post-operative sequelae, as well as morbidity and mortality within 90 days. All complications were graded using the Clavien-Dindo (CD) Grading System. The highest-grade of complication was used per patient during 30-day and 31-90-day intervals.

Out of 2342 patients, the overall 30-day morbidity and mortality rates were 18.2% (427/2342) and 0.2% (4/2342), respectively. Most of the complications were CD<3a at 13.1% (306/2342). In the 31-90-day post-operative period, morbidity and mortality rates decreased to 3.1% (78/2338) and 0.09% (2/2338). CD<3a complications accounted for 1.9% (42/2338).

Anti-reflux and hiatal hernia surgery are safe operations with rare mortality and modest rates of morbidity. However, the majority of complications patients experience are minor (CD<3a) and are easily managed. A minority of patients will experience major complications (CD≥3a) that require additional procedures and management to secure a safe outcome. These data are helpful to inform patients of the risks of surgery, and guide physicians for optimal consent.

Impostor Phenomenon and Impact on Women Surgeons: A Canadian Cross-Sectional Survey.

Journal of the

This project aims to characterize the extent and nature of IP among women surgeons in Canada. Impostor Phenomenon (IP) is well documented among medical professionals and trainees. It is known to have significant impacts on mental health and career trajectory.

We conducted a cross-sectional survey of self-identifying women who have completed a surgical residency and currently or most recently practiced in Canada.

Among 387 respondents, 98.7% have experienced IP. Median IP score corresponded to frequent impostor feelings or high impostorism. Self-doubt affects most women surgeons for the first time during training. It tends to be most intense in the first 5 years of practice and lessens over time. 112 surgeons (31.5%) experience self-doubt in the OR. Due to self-doubt, 110 respondents (28.4%) preferred to work with a more experienced assistant in the OR, while 40 (10.4%) stated that they would only operate with an experienced assistant. Few surgeons take on less OR time due to self-doubt (29 (7.5%)) but 60 (16.5%) take on less complex cases due to self-doubt. A small but important number of surgeons (11 (2.8%)) had given up operating altogether due to self-doubt. Due to feelings of self-doubt, 107 (21.4%) were hesitant to take on a leadership role in the workplace.

IP is a nearly universal experience among women surgeons and is influential in their professional lives. This study contributes to scientific knowledge that can advance gender equity in medicine and leadership.

Long-Term Cardiovascular Outcomes in Children and Adolescents With Hypertension.

JAMA Pediatrics

Hypertension affects 6% of all children, and its prevalence is increasing. Childhood hypertension tracks into adulthood and is associated with subclinical cardiovascular disease; however, there is a lack of evidence linking childhood hypertension to cardiovascular outcomes, which may contribute to underdiagnosis and undertreatment.

To determine the long-term associated risk of major adverse cardiac events (MACE) among children diagnosed with hypertension.

This was a population-based, retrospective, matched cohort study conducted from 1996 to 2022. The study included all children (aged 3-18 years) alive in Ontario, Canada, from 1996 to 2021, who were identified using provincial administrative health databases. Children with prior kidney replacement therapy were excluded.

Incident hypertension diagnosis, identified by validated case definitions using diagnostic and physician billing claims. Each case was matched with 5 controls without hypertension by age, sex, birth weight, maternal gestational hypertension, prior comorbidities (chronic kidney disease, diabetes, cardiovascular surgery), and a propensity score for hypertension.

The primary outcome was MACE (a composite of cardiovascular death, stroke, hospitalization for myocardial infarction or unstable angina, or coronary intervention). Time to MACE was evaluated using the Kaplan-Meier method and Cox proportional hazards regression.

A total of 25 605 children (median [IQR] age, 15 [11-17] years; 14 743 male [57.6%]) with hypertension were matched to 128 025 controls without hypertension. Baseline covariates were balanced after propensity score matching, and prior comorbidities were uncommon (hypertension vs control cohort: malignancy, 1451 [5.7%] vs 7908 [6.2%]; congenital heart disease, 1089 [4.3%] vs 5408 [4.2%]; diabetes, 482 [1.9%] vs 2410 [1.9%]). During a median (IQR) of 13.6 (7.8-19.5) years of follow-up, incidence of MACE was 4.6 per 1000 person-years in children with hypertension vs 2.2 per 1000 person-years in controls (hazard ratio, 2.1; 95% CI, 1.9-2.2). Children with hypertension were at higher associated risk of stroke, hospitalization for myocardial infarction or unstable angina, coronary intervention, and congestive heart failure, but not cardiovascular death, compared with nonhypertensive controls.

Children diagnosed with hypertension had a higher associated long-term risk of MACE compared with controls without hypertension. Improved detection, follow-up, and control of pediatric hypertension may reduce the risk of adult cardiovascular disease.

Relaxation Therapy and Human Milk Feeding Outcomes: A Systematic Review and Meta-Analysis.

JAMA Pediatrics

Human milk feeding is a key public health goal to optimize infant and maternal/parental health, but global lactation outcomes do not meet recommended duration and exclusivity. There are connections between lactation and mental health.

To appraise all available evidence on whether the provision of relaxation interventions to lactating individuals improves lactation and well-being.

Embase, MEDLINE, CINAHL, Allied and Complementary Medicine Database, Web of Science, and the Cochrane Library were searched on September 30, 2023, and topic experts were consulted.

Two independent reviewers screened for eligibility. Inclusion criteria were full-text, peer-reviewed publications with a randomized clinical trial design. Techniques that were entirely physical (eg, massage) were excluded. A total of 7% of initially identified studies met selection criteria.

Two independent reviewers extracted data and assessed risk of bias with the Cochrane Risk of Bias 2 tool. Fixed-effects meta-analysis and Grading of Recommendations, Assessment, Development, and Evaluations guidelines were used to synthesize and present evidence.

Prespecified primary outcomes were human milk quantity, length and exclusivity of human milk feeding, milk macronutrients/cortisol, and infant growth and behavior.

A total of 16 studies were included with 1871 participants (pooled mean [SD] age for 1656 participants, 29.6 [6.1] years). Interventions were music, guided relaxation, mindfulness, and breathing exercises/muscle relaxation. Provision of relaxation was not associated with a change in human milk protein (mean difference [MD], 0 g/100 mL; 95% CI, 0; 205 participants). Provision of relaxation was associated with an increase in human milk quantity (standardized mean difference [SMD], 0.73; 95% CI, 0.57-0.89; 464 participants), increased infant weight gain in breastfeeding infants (MD, z score change = 0.51; 95% CI, 0.30-0.72; 226 participants), and a slight reduction in stress and anxiety (SMD stress score, -0.49; 95% CI, -0.70 to -0.27; 355 participants; SMD anxiety score, -0.45; 95% CI, -0.67 to -0.22; 410 participants).

Results of this systematic review and meta-analysis suggest that provision of relaxation was associated with an increase in human milk quantity and infant weight gain and a slight reduction in stress and anxiety. Relaxation interventions can be offered to lactating parents who would like to increase well-being and improve milk supply or, where directly breastfeeding, increase infant weight gain.

Drivers of Variation in Opioid Prescribing after Common Surgical Procedures in a Large Multihospital Healthcare System.

Journal of the

Misuse of prescription opioids is a well-established contributor to the United States opioid epidemic. The primary objective of this study was to identify which level of care delivery (i.e. patient, prescriber, or hospital) produced the most unwarranted variation in opioid prescribing after common surgical procedures.

Electronic health record (EHR) data from a large multihospital healthcare system was used in conjunction with random-effect models to examine variation in opioid prescribing practices following similar inpatient and outpatient surgical procedures between October 2019 and September 2021. Unwarranted variation was conceptualized as variation resulting from prescriber behavior unsupported by evidence. Covariates identified as drivers of warranted variation included characteristics known to influence pain levels or patient safety. All other model variables, including prescriber specialty and patient race, ethnicity, and insurance status were characterized as potential drivers of unwarranted variation.

Among 25,188 procedures with an opioid prescription at hospital discharge, 53.5% exceeded guideline recommendations, corresponding to 13,228 patients receiving the equivalent of >140,000 excess 5mg oxycodone tablets following surgical procedures. Prescribing variation was primarily driven by prescriber-level factors, with approximately half of the total variation in morphine milligram equivalents (MMEs) prescribed observed at the prescriber level and not explained by any measured variables. Unwarranted covariates associated with higher prescribed opioid quantity included non-Hispanic black race, Medicare insurance, smoking history, later hospital discharge times, and prescription by a surgeon rather than a hospitalist or primary care provider.

Given the large proportion of unexplained variation observed at the provider level, targeting prescribers through education and training may be an effective strategy for reducing postoperative opioid prescribing.

Physical Fitness and Risk of Mental Disorders in Children and Adolescents.

JAMA Pediatrics

With the rising prevalence of mental disorders among children and adolescents, identifying modifiable associations is critical.

To examine the association between physical fitness and mental disorder risks.

This nationwide cohort study used data from the Taiwan National Student Fitness Tests and National Health Insurance Research Databases from January 1, 2009 to December 31, 2019. Participants were divided into 2 cohorts targeting anxiety and depression (1 996 633 participants) and attention-deficit/hyperactivity disorder (ADHD; 1 920 596 participants). Participants were aged 10 to 11 years at study entry and followed up for at least 3 years, had a nearly equal gender distribution, and an average follow-up of 6 years. Data were analyzed from October 2022 to February 2024.

Assessments of physical fitness included cardiorespiratory fitness (CF), muscular endurance (ME), muscular power (MP), and flexibility, measured through an 800-m run time, bent-leg curl-ups, standing broad jump, and sit-and-reach test, respectively.

Kaplan-Meier method calculated the cumulative incidence of anxiety, depression, and ADHD across fitness quartiles. Additionally, multivariable Cox proportional hazards models were used that included all 4 fitness components and explored sex and income as modifiers.

The anxiety and depression cohort had 1 996 633 participants (1 035 411 participants were male [51.9%], and the median [IQR] age was 10.6 [10.3-11.0] years), while the ADHD cohort had 1 920 596 (975 568 participants were male [51.9%], and the median [IQR] age was 10.6 [10.3-11.0] years). Cumulative incidence of mental disorders was lower among participants in better-performing fitness quartiles, suggesting a dose-dependent association. Gender-specific analyses, controlling for confounders, revealed that improved CF, indicated by a 30-second decrease in run times, was associated with reduced risks of anxiety, depression, and ADHD in female participants, and lower risks of anxiety and ADHD in male participants (adjusted hazard ratio [aHR] for ADHD risk for female participants, 0.92; 95% CI, 0.90-0.94; P < .001; for male participants, 0.93; 95% CI, 0.92-0.94; P < .001). Enhanced ME, marked by an increase of 5 curl-ups per minute, was associated with decreased risks of depression and ADHD in female participants, and lower anxiety and ADHD risks in male participants (aHR for ADHD risk for female participants, 0.94; 95% CI, 0.92-0.97; P < .001; for male participants, 0.96; 95% CI, 0.95-0.97; P < .001). Improved MP, reflected by a 20-cm increase in jump distance, was associated with reduced risks of anxiety and ADHD in female participants and reduced anxiety, depression, and ADHD in male participants (aHR for ADHD risk for female participants, 0.95; 95% CI, 0.91-1.00; P = .04; for male participants, 0.96; 95% CI, 0.94-0.99; P = .001).

This study highlights the potential protective role of cardiorespiratory fitness, muscular endurance, and muscular power in preventing the onset of mental disorders. It warrants further investigation of the effectiveness of physical fitness programs as a preventive measure for mental disorders among children and adolescents.

Clinical Outcomes of a Large, Prospective Series of Gastric Electrical Stimulation Patients Using a Multidisciplinary Protocol.

Journal of the

Gastric electrical stimulation (GES) is an intervention used in the treatment of medically refractory gastroparesis. There are few large series demonstrating efficacy over a long-term follow-up period. This study reports clinical outcomes for patients from a single institution up to 5 years.

A prospective database of patients undergoing GES implantation for gastroparesis was collected and reviewed. Patients were selected according to a multi-disciplinary institutional protocol. Baseline characteristics, including age, sex, smoking history, etiology of gastroparesis, and duration of gastroparesis symptoms, were collected. Symptomatic response was evaluated utilizing Gastroparesis Cardinal Symptom Index (GCSI) surveys pre-operatively and at subsequent follow-up visits. Other clinical outcome variables include medication use, hospitalizations due to gastroparesis, and overall satisfaction with symptom relief. Patient outcomes regarding reoperation and explantation were also recorded.

157 patients underwent GES at our institution since 2012. GCSI scores were collected in all patients at baseline, in 141 patients at 1 year follow-up, and in 110 patients at 5 years follow-up. Symptom severity in all 9 gastroparesis symptoms evaluated by the GCSI, as well as the total GCSI score, was reduced significantly at 1 year post-operatively, and these results were sustained at 5-year follow-up. Use of prokinetic and antiemetic medications was reduced during the follow-up period. Hospitalizations due to gastroparesis symptoms were also reduced. GES devices were explanted in 5 patients, 12 patients required generator exchanges, and 7 patients required reoperation due to displaced/eroded device leads during the study period.

Gastric electrical stimulation is associated with sustained symptomatic relief, reduced reliance on medications, and reduced hospitalizations in gastroparesis patients selected utilizing our institutional protocol.
