Realizing Inclusion and Systemic Equity in Medicine: Upstanding in the Medical Workplace (RISE UP)-an Antibias Curriculum.

Introduction: Racism is a public health threat, and racist behaviors adversely affect clinicians in addition to patients. Medical trainees commonly experience racism and bias. More than half of pediatric residents at a single institution reported experiencing or witnessing discriminatory behavior at work; only 50% reported receiving training on implicit bias, delivering difficult feedback, or peer support. Our multispecialty team created Realizing Inclusion and Systemic Equity in Medicine: Upstanding in the Medical Workplace (RISE UP), an antibias, anti-racism communication curriculum composed of three hybrid (virtual and in-person) workshops. Methods: During the pediatric resident workshops, we introduced tools for addressing bias, presented video simulations, and led small-group debriefings with guided role-play. We also reviewed escalation pathways, reporting methods, and support systems. Residents completed an evaluation before and after each workshop to assess the curriculum's efficacy. Results: Thirty-nine residents participated in RISE UP, with 20 attending all three workshops. Ninety-six percent of participants indicated they would recommend the workshops to colleagues. After the third workshop, 92% reported having tools to respond to bias, and 85% reported knowing how to escalate concerns regarding discriminatory behavior. Chief residents were most frequently identified as sources of resident support when encountering discriminatory behavior. Discussion: This curriculum was successful in developing and strengthening residents' responses to discrimination, including upstander support. The curriculum is adaptable for virtual, in-person, and hybrid settings, allowing for flexibility. Establishing institutional support, promoting faculty development, and creating and disseminating escalation pathways are critical to addressing racism in health care.

Longitudinal outcomes of body mass index in overweight and obese children with chronic kidney disease.

BACKGROUND: Longitudinal changes in body mass index (BMI) among overweight and obese children with chronic kidney disease (CKD) are not well characterized. We studied longitudinal trajectories and correlates of these trajectories, as results may identify opportunities to optimize health outcomes. METHODS: Longitudinal changes in age-sex-specific BMI z-scores over 1851 person-years of follow-up were assessed in 524 participants of the Chronic Kidney Disease in Children Study. A total of 353 participants were categorized as normal (BMI > 5th to < 85th percentile), 56 overweight (BMI ≥ 85th to 95th percentile) and 115 obese (BMI ≥ 95th percentile) based on the average of three BMI measurements during the first year of follow-up. Studied covariates included age, sex, race, CKD etiology, corticosteroid usage, household income, and maternal education. RESULTS: In unadjusted analysis, BMI z-scores decreased over time in elevated BMI groups (overweight: mean = - 0.06 standard deviations (SD) per year, 95% CI: - 0.11, - 0.01; obese: mean = - 0.04 SD per year, 95% CI: - 0.07, - 0.01). Among obese children, only age was associated with change in BMI z-score; children < 6 years had a mean decrease of 0.19 SD during follow-up (95% CI: - 0.30, - 0.09). Socioeconomic factors were not associated with change in BMI. CONCLUSION: Overweight and obese children with CKD demonstrated a significant annual decline in BMI, though the absolute change was modest. Among obese children, only age < 6 years was associated with significant decline in BMI. Persistence of elevated BMI in older children and adolescents with CKD underscores the need for early prevention and effective intervention.

Perceived appetite and clinical outcomes in children with chronic kidney disease.

BACKGROUND: Children with chronic kidney disease (CKD) may have impaired caloric intake through a variety of mechanisms, with decreased appetite as a putative contributor. In adult CKD, decreased appetite has been associated with poor clinical outcomes. There is limited information about this relationship in pediatric CKD. METHODS: A total of 879 participants of the Chronic Kidney Disease in Children (CKiD) study were studied. Self-reported appetite was assessed annually and categorized as very good, good, fair, or poor/very poor. The relationship between appetite and iohexol or estimated glomerular filtration rate (ieGFR), annual changes in anthropometrics z-scores, hospitalizations, emergency room visits, and quality of life were assessed. RESULTS: An ieGFR < 30 ml/min per 1.73 m(2) was associated with a 4.46 greater odds (95 % confidence interval: 2.80, 7.09) of having a worse appetite than those with ieGFR >90. Appetite did not predict changes in height, weight, or BMI z-scores. Patients not reporting a very good appetite had more hospitalizations over the next year than those with a very good appetite. Worse appetite was significantly associated with lower parental and patient reported quality of life. CONCLUSIONS: Self-reported appetite in children with CKD worsens with lower ieGFR and is correlated with clinical outcomes, including hospitalizations and quality of life.

Preactivation of AMPK by metformin may ameliorate the epithelial cell damage caused by renal ischemia.

Alterations in epithelial cell polarity and in the subcellular distributions of epithelial ion transport proteins are key molecular consequences of acute kidney injury and intracellular energy depletion. AMP-activated protein kinase (AMPK), a cellular energy sensor, is rapidly activated in response to renal ischemia, and we demonstrate that its activity is upregulated by energy depletion in Madin-Darby canine kidney (MDCK) cells. We hypothesized that AMPK activity may influence the maintenance or recovery of epithelial cell organization in mammalian renal epithelial cells subjected to energy depletion. MDCK cells were ATP depleted through a 1-h incubation with antimycin A and 2-deoxyglucose. Immunofluoresence localization demonstrated that this regimen induces mislocalization of the Na-K-ATPase from its normal residence at the basolateral plasma membrane to intracellular vesicular compartments. When cells were pretreated with the AMPK activator metformin before energy depletion, basolateral localization of Na-K-ATPase was preserved. In MDCK cells in which AMPK expression was stably knocked down with short hairpin RNA, preactivation of AMPK with metformin did not prevent Na-K-ATPase redistribution in response to energy depletion. In vivo studies demonstrate that metformin activated renal AMPK and that treatment with metformin before renal ischemia preserved cellular integrity, preserved Na-K-ATPase localization, and led to reduced levels of neutrophil gelatinase-associated lipocalin, a biomarker of tubular injury. Thus AMPK may play a role in preserving the functional integrity of epithelial plasma membrane domains in the face of energy depletion. Furthermore, pretreatment with an AMPK activator before ischemia may attenuate the severity of renal tubular injury in the context of acute kidney injury.
