Feasibility and reliability of measured glomerular filtration rate with [I125]-iothalamate among young adults with mild-to-moderate cerebral palsy.

Objective: Despite the need, measuring glomerular filtration rate (mGFR) is not routinely performed for adults with cerebral palsy (CP), possibly due to unknown feasibility given the secondary complications of CP. This study aimed to assess the feasibility and reliability of mGFR and explore factors associated with eGFR-mGFR discordance among young adults with mild-to-moderate CP. Methods: This single-center, cross-sectional study included 18- to 40-year-olds with CP gross motor function classification system (GMFCS) I-III. The participants were excluded if they were pregnant/lactating, had cognitive impairments, or had contraindications to mGFR. A routine clinical protocol for mGFR and eGFR was used. mGFR feasibility was assessed based on the number of participants who completed testing. mGFR reliability was assessed using the coefficient of variation (CV) across the four 30 min intervals. The association between age, sex, and GMFCS and the percentage of eGFR-mGFR discordance was assessed. Results: Of the 19 participants enrolled, 18 completed the testing [mean age (SD), 29.9 (7.4) years, n = 10 female participants, n = 10/3/5 for GMFCS I/II/III] and most (n = 15) of the participants had an mGFR >90 mL/min; 14 participants (77.8%) had a CV <20%, 2 had a CV between 20 and 25%, and 2 had a CV >50%. eGFR overestimated mGFR by a median (interquartile range) of approximately 17.5% (2-38%); the full range of mis-estimation was -20.5 to 174.3%. Increasing age and GMFCS levels exhibited notable, but weak-to-modest, associations with a larger eGFR-mGFR discordance. Discussion: Obtaining mGFR was feasible and reasonably reliable within this small sample. eGFR overestimated mGFR by a notable amount, which may be associated with patient-level factors.

Responding to the ripple effects of sexual harassment: an emergency management framework.

Sexual harassment in academia is endemic driven by gender-based inequalities and sustained through organizational tolerance, and its impact extends beyond the primary victim(s). Applying principles of emergency management provides a framework for institutions to balance their obligations to the primary victim(s) while also acknowledging the need to restore the well-being and culture of secondary victims.

Supporting Patient-Centered Pregnancy Counseling in Nephrology Care: A Semistructured Interview Study of Patients and Nephrologists.

Introduction: Individuals with chronic kidney disease (CKD) are at increased risk of adverse pregnancy outcomes and are susceptible to disempowerment and decisional burden when receiving reproductive counseling and considering pregnancy. Nephrologists do not frequently counsel about reproductive health, and no tools exist to support patient-centered reproductive counseling for those with CKD. Methods: A total of 30 patients aged 18 to 45 years with CKD stages 1 to 5 who were assigned female sex at birth and 12 nephrologists from a single academic medical center participated in semistructured qualitative interviews. They were asked about information needs, decision support needs, and facilitators and barriers to reproductive health care and counseling. Thematic analysis was performed. Results: The following 4 main themes were identified: (i) assessing reproductive intentions; (ii) information about reproductive health and kidney disease; (iii) reproductive risk; and (iv) communication and decision-making needs. Patients' reproductive intentions varied over time and shaped the content of information needed from nephrologists. Patients and nephrologists both felt that risk communication could be improved but focused on different aspects to improve the quality of this counseling; nephrologists focused on providing individualized risk estimates and patients focused on balancing risks with benefits and management. Patients desired nephrologists to bring up the topic of reproductive health and counseling in kidney clinic, and this is not frequently or systematically done currently. Conclusion: This work highlights a critical need for more dialog about reproductive health in kidney care, identified differences in what patients and nephrologists think is important in communication and decision-making, and provides an important step in developing patient-centered reproductive counseling tools in nephrology.

Pregnancy History and Kidney Disease Progression Among Women Enrolled in Cure Glomerulonephropathy.

Introduction: Preeclampsia increases the risk for future chronic kidney disease (CKD). Among those diagnosed with CKD, it is unclear whether a prior history of preeclampsia, or other complications in pregnancy, negatively impact kidney disease progression. In this longitudinal analysis, we assessed kidney disease progression among women with glomerular disease with and without a history of a complicated pregnancy. Methods: Adult women enrolled in the Cure Glomerulonephropathy study (CureGN) were classified based on a history of a complicated pregnancy (defined by presence of worsening kidney function, proteinuria, or blood pressure; or a diagnosis of preeclampsia, eclampsia, or hemolysis, elevated liver enzymes, and low platelets [HELLP] syndrome), pregnancy without these complications, or no pregnancy history at CureGN enrollment. Linear mixed models were used to assess estimated glomerular filtration rate (eGFR) trajectories and urine protein-to-creatinine ratios (UPCRs) from enrollment. Results: Over a median follow-up period of 36 months, the adjusted decline in eGFR was greater in women with a history of a complicated pregnancy compared to those with uncomplicated or no pregnancies (-1.96 [-2.67, -1.26] vs. -0.80 [-1.19, -0.42] and -0.64 [-1.17, -0.11] ml/min per 1.73 m2 per year, P = 0.007). Proteinuria did not differ significantly over time. Among those with a complicated pregnancy history, eGFR slope did not differ by timing of first complicated pregnancy relative to glomerular disease diagnosis. Conclusions: A history of complicated pregnancy was associated with greater eGFR decline in the years following glomerulonephropathy (GN) diagnosis. A detailed obstetric history may inform counseling regarding disease progression in women with glomerular disease. Continued research is necessary to better understand pathophysiologic mechanisms by which complicated pregnancies contribute to glomerular disease progression.

Gendered Language in Letters of Recommendation for Applicants to Pulmonary Critical Care Fellowships.

Background: Previous work has demonstrated letters of recommendation for women in academic medicine are shorter and emphasize communal traits over grindstone or agentic traits. Objective: To determine if there are sex-based differences in letters of recommendation written for applicants applying to pulmonary critical care medicine fellowships and if the sex of the letter writer impacts these differences. Methods: All fellowship applications submitted to a pulmonary critical care medicine fellowship program in 2020 were included in this study. The applicant demographics and self-reported accomplishments were extracted from their application. The sex of letter writers was identified through public online searches. Word count and language differences in the letters of recommendation were analyzed for each applicant using the Linguistic Inquiry and Word Count (LIWC2015) program. Multivariable linear regressions were performed controlling for applicant characteristics to identify if applicant sex was associated with total word counts and total agentic word counts. Results: Of the 529 complete applications, 2,024 letters of recommendation were reviewed. A majority of the applicants (70%, n = 370/530) and letter writers (75%, n = 1,515/2,024) were male. When adjusting for applicant demographic and accomplishments, female applicants had longer letters of recommendation (30.91 words longer, 95% confidence interval [CI], 1.53-60.29; P = 0.04) and more supportive letters (3.27 words longer, 95% CI, 1.59-4.95; P < 0.01) as compared with male applicants. Female letter writers wrote longer and more supportive letters than male letter writers, and this difference was greatest for female applicants. Conclusion: Female applicants received longer and more supportive letters of recommendation. Further work is needed to understand if this finding is the beginning of a change in the letters of recommendation for female applicants.

Pregnancy and CKD: Advances in Care and the Legacy of Dr Susan Hou.

Dr Susan Hou began her illustrious nephrology career at a time when pregnancy in women with chronic kidney disease (CKD) was hazardous and actively discouraged. Her pioneering research in women's health provided much of the early outcome data that shaped our current understanding of CKD and pregnancy. Although many uncertainties regarding optimal management of this vulnerable patient group remain, recent decades have witnessed important advances and renewed interest in improving care for pregnant women with CKD. Many nephrologists have been inspired by Dr Hou's lifetime of work and are grateful for her generous collaborations. In this In Practice Review, we honor her legacy by providing an update of current literature and clinical management guidance in the context of a clinical case vignette that challenges us to consider the many complex aspects to the counseling and care of women with CKD who desire a pregnancy.

The Association Between Kidney Disease and Mortality Among Adults With Cerebral Palsy-A Cohort Study: It Is Time to Start Talking About Kidney Health.

Objective: Recent evidence shows that adults with cerebral palsy (CP) have an increased risk for kidney disease, but nothing is known about how kidney disease integrates with their overall health. To begin understanding the importance of kidney health, the objective was to determine if kidney disease is associated with mortality among adults with CP after accounting for comorbidities common to CP and kidney disease. Methods: Data from 2016 to 2018 from adults ≥18 years with CP were used from a random 20% sample fee-for-service Medicare database. Kidney disease in 2016 was ascertained as chronic kidney disease (CKD) stages 1-4, end stage kidney disease (ESKD), nephritic and nephrotic syndrome, and renal osteodystrophy. A modified version of the Whitney Comorbidity Index (modWCI) was used, which includes 24 comorbidities relevant to CP and kidney disease. Mortality rate ratio (MRR) through the year 2018 was estimated for each kidney disease and Cox regression estimated the hazard ratio (HR) of mortality after adjusting for demographics, co-occurring neurological conditions, and the modWCI. Results: Prevalence of kidney disease was 7.3% among 16,728 adults with CP. MRR was elevated for any kidney disease (MRR = 3.14; 95%CI = 2.76-3.58) and most subtypes (MRR = 2.21-3.56; all p < 0.05). The adjusted HR of mortality remained elevated for any kidney disease (HR = 1.25; 95%CI = 1.09-1.45) and ESKD (HR = 1.38; 95%CI = 1.10-1.74). Discussion: Kidney disease, especially ESKD, is associated with mortality among adults with CP independent of comorbidities that are relevant to CP and kidney disease. Findings suggest that nephrology care should be considered as part of routine clinical care for this population.

Validating a Computable Phenotype for Nephrotic Syndrome in Children and Adults Using PCORnet Data.

Background: Primary nephrotic syndromes are rare diseases which can impede adequate sample size for observational patient-oriented research and clinical trial enrollment. A computable phenotype may be powerful in identifying patients with these diseases for research across multiple institutions. Methods: A comprehensive algorithm of inclusion and exclusion ICD-9 and ICD-10 codes to identify patients with primary nephrotic syndrome was developed. The algorithm was executed against the PCORnet CDM at three institutions from January 1, 2009 to January 1, 2018, where a random selection of 50 cases and 50 noncases (individuals not meeting case criteria seen within the same calendar year and within 5 years of age of a case) were reviewed by a nephrologist, for a total of 150 cases and 150 noncases reviewed. The classification accuracy (sensitivity, specificity, positive and negative predictive value, F1 score) of the computable phenotype was determined. Results: The algorithm identified a total of 2708 patients with nephrotic syndrome from 4,305,092 distinct patients in the CDM at all sites from 2009 to 2018. For all sites, the sensitivity, specificity, and area under the curve of the algorithm were 99% (95% CI, 97% to 99%), 79% (95% CI, 74% to 85%), and 0.9 (0.84 to 0.97), respectively. The most common causes of false positive classification were secondary FSGS (nine out of 39) and lupus nephritis (nine out of 39). Conclusion: This computable phenotype had good classification in identifying both children and adults with primary nephrotic syndrome utilizing only ICD-9 and ICD-10 codes, which are available across institutions in the United States. This may facilitate future screening and enrollment for research studies and enable comparative effectiveness research. Further refinements to the algorithm including use of laboratory data or addition of natural language processing may help better distinguish primary and secondary causes of nephrotic syndrome.

A theoretical model of contraceptive decision-making and behaviour in diabetes: A qualitative application of the Health Belief Model.

AIM: People with diabetes have contraceptive needs that have been inadequately addressed. The aim of this qualitative study was to develop a theoretical model that reflects contraceptive decision-making and behaviour in the setting of diabetes mellitus. METHODS: We conducted semi-structured, qualitative interviews of 17 women with type 1 or type 2 diabetes from Michigan, USA. Participants were recruited from a diabetes registry and local clinics. We adapted domains from the Health Belief Model (HBM) and applied reproductive justice principles to inform the qualitative data collection and analysis. Using an iterative coding template, we advanced from descriptive to theoretical codes, compared codes across characteristics of interest (e.g. diabetes type), and synthesized the theoretical codes and their relationships in an explanatory model. RESULTS: The final model included the following constructs and themes: perceived barriers and benefits to contraceptive use (effects on blood sugar, risk of diabetes-related complications, improved quality of life); perceived seriousness of pregnancy (harm to self, harm to foetus or baby); perceived susceptibility to pregnancy risks (diabetes is a 'high risk' state); external cues to action (one-size-fits-all/anxiety-provoking counselling vs. personalized/trust-based counselling); internal cues to action (self-perceived 'sickness'); self-efficacy (reproductive self-efficacy, contraceptive self-efficacy); and modifying factors (perceptions of biased counselling based upon one's age, race or severity of disease). CONCLUSIONS: This novel adaptation of the HBM highlights the need for condition-specific and person-centred contraceptive counselling for those with diabetes.

End-Stage Kidney Disease and Dialysis in Pregnancy.

End-stage kidney disease is associated with low fertility, with rates of conception in women on dialysis estimated at 1/100th of the general population. However, live birth rates are increasing over time in women on hemodialysis, whereas they remain lower and static in women on peritoneal dialysis. Intensification of hemodialysis, targeting a serum blood urea nitrogen <35 mg/dL or 36 hours of dialysis per week in women with no residual kidney function, is associated with improved live birth rates and longer gestational age. Even in intensively dialyzed cohorts, rates of prematurity and need for neonatal intensive care are high, upwards of 50%. Although women on peritoneal dialysis in pregnancy do not appear to be at increased risk of delivering preterm compared with those on hemodialysis, their infants are more likely to be small for gestational age. As such, hemodialysis has emerged as the preferred dialysis modality in pregnancy. Provision of specialized nephrology, obstetric, and neonatal care is necessary to manage these complex pregnancies and family planning counseling should be offered to all women with end-stage kidney disease.

Advanced CKD Among Adults With Cerebral Palsy: Incidence and Risk Factors.

RATIONALE & OBJECTIVE: Recent evidence suggests that adults with cerebral palsy have an elevated risk for developing advanced chronic kidney disease (CKD). To develop effective interventions, the objective was to identify whether demographics and preexisting medical conditions are risk factors for advanced CKD among adults with cerebral palsy. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Data were from the Optum Clinformatics Data Mart. Adults 18 years or older with cerebral palsy and without advanced CKD (CKD stage 4 or later) were identified from 2013 and subsequently followed up from January 1, 2014, to the development of advanced CKD, death, loss to follow-up, or end of the study period (December 31, 2017), whichever came first. Diagnostic, procedure, and diagnosis-related group codes were used to identify cerebral palsy, incident cases of advanced CKD, comorbid intellectual disability, and 10 preexisting medical conditions. EXPOSURES: Demographic variables and 10 preexisting medical conditions: CKD stages 1-3, hypertension, diabetes, heart and cerebrovascular disease, non-CKD urologic conditions, bowel conditions, respiratory disease, skeletal fragility, arthritis, and dysphagia. OUTCOME: Incidence of advanced CKD. ANALYTIC APPROACH: Crude incidence rate (IR) of advanced CKD and IR ratios with 95% CIs were estimated. Cox proportional hazards regression models that were adjusted for demographics, intellectual disability, and preexisting medical conditions were used to evaluate the adjusted independent effect of predictor variables. RESULTS: 237 of the 8,011 adults with cerebral palsy developed advanced CKD during follow-up (IR, 10.16/1,000 person years; 95% CI, 8.87-11.46). In the crude analysis, all preexisting medical conditions were associated with an elevated IR and IR ratio of advanced CKD. In the fully adjusted Cox proportional hazards regression model, the HR was elevated for older age, CKD stages 1-3 (HR, 3.32; 95% CI, 2.39-4.61), diabetes (HR, 2.69; 95% CI, 2.03-3.57), hypertension (HR, 1.54; 95% CI, .10-2.16), heart and cerebrovascular disease (HR, 1.53; 95% CI, 1.12-2.07), and non-CKD urologic conditions (HR, 1.39; 95% CI, 1.05-1.84). LIMITATIONS: Private insurance database, short follow-up period, and lack of laboratory values, such as albuminuria/proteinuria. CONCLUSIONS: Advanced CKD was common among adults with cerebral palsy and its development was associated with both traditional and nontraditional urologic risk factors.
