Maternal racial and ethnic disparities in glycemic threshold for pharmacotherapy initiation for gestational diabetes.

OBJECTIVE: To compare the glycemic threshold for pharmacotherapy initiation in women with gestational diabetes (GDM) based on maternal race/ethnicity. METHODS: A retrospective cohort study of women with GDM who received pharmacotherapy during pregnancy, in addition to diet and exercise, between 2015 and 2019 in a university center. The primary outcome was percent of elevated capillary blood glucoses (CBGs) prior to pharmacotherapy initiation. This was compared between four maternal racial and ethnic groups: non-Hispanic white (NHW), non-Hispanic black (NHB), Hispanic and other race and ethnicity group that included Asian, American Indian and Alaskan Native. Univariable and multivariable analyses were done to estimate whether there was an independent association between maternal race and ethnicity and the percent of elevated CBGs prior to pharmacotherapy initiation. RESULTS: A total of 440 women met inclusion criteria. In univariable analysis, NHB women, Hispanic, and women of other race and ethnicity had higher percent of elevated CBGs prior to pharmacotherapy initiation, compared to NHW women (45.5 ± 22.5% for NHW, 65.2 ± 25.4% for NHB, 58.3 ± 21.7% for Hispanic and 51.6 ± 26.8% for other race and ethnicity, respectively, p < .001). After the adjustment for maternal demographic and clinical factors, maternal race and ethnicity remained to be significantly associated with timing of pharmacotherapy initiation, with women of racial and ethnic minority having a higher percent of elevated CBGs prior to pharmacotherapy initiation (adjusted linear regression coefficient 18.1, 95% CI 11.3-25.0 for NHB, adjusted linear regression coefficient 13.2, 95% CI 5.0-21.4 for Hispanic, and adjusted linear regression coefficient 9.8, 95% CI 2.6-16.9 for women of other race and ethnicity). CONCLUSION: A significant variation was identified in glycemic threshold for pharmacotherapy initiation in women with GDM across different maternal racial and ethnic groups with minority women starting pharmacotherapy at higher percent of elevated CBGs.

Correlates of Insulin Selection as a First-Line Pharmacological Treatment for Gestational Diabetes.

OBJECTIVE: The aim of this study was to investigate prenatal factors associated with insulin prescription as a first-line pharmacotherapy for gestational diabetes mellitus (GDM; compared with oral antidiabetic medication) after failed medical nutrition therapy. STUDY DESIGN: This is a retrospective cohort study of 437 women with a singleton pregnancy and diagnosis of A2GDM (GDM requiring pharmacotherapy), delivering in a university hospital between 2015 and 2019. Maternal sociodemographic and clinical characteristics, as well as GDM-related factors, including provider type that manages GDM, were compared between women who received insulin versus oral antidiabetic medication (metformin or glyburide) as the first-line pharmacotherapy using univariable and multivariable analyses. RESULTS: In univariable analysis, maternal age, race and ethnicity, insurance, chronic hypertension, gestational age at GDM diagnosis, glucose level after 50-g glucose loading test, and provider type were associated with insulin prescription. In multivariable analysis, after adjusting for sociodemographic and clinical maternal factors, GDM characteristics and provider type, Hispanic ethnicity (0.26, 95% confidence interval [CI]: 0.09-0.73), and lack of insurance (0.34, 95% CI: 0.13-0.89) remained associated with lower odds of insulin prescription, whereas endocrinology management of GDM (compared with obstetrics and gynecology [OBGYN]) (8.07, 95% CI: 3.27-19.90) remained associated with higher odds of insulin prescription. CONCLUSION: Women of Hispanic ethnicity and women with no insurance were less likely to receive insulin and more likely to receive oral antidiabetic medication for GDM pharmacotherapy, while management by endocrinology was associated with higher odds of insulin prescription.This finding deserves more investigation to understand if differences are due to patient choice or a health disparity in the choice of pharmacologic agent for A2GDM. KEY POINTS: · Insulin is recommended as a first-line pharmacotherapy for gestational diabetes.. · Women of Hispanic ethnicity were less likely to receive insulin as first line.. · Lack of insurance was also associated with lower odds of insulin prescription..

Comparison of Lag Versus Nonlag Screw Fixation for Long Oblique Proximal Phalanx Fractures: A Biomechanical Study.

PURPOSE: To compare lag versus nonlag screw fixation for long oblique proximal phalanx (P1) fractures in a cadaveric model of finger motion via the flexor and extensor tendons. METHODS: We simulated long oblique P1 fractures with a 45° oblique cut in the index, middle, and ring fingers of 4 matched pairs of cadaveric hands for a total of 24 simulated fractures. Fractures were stabilized using 1 of 3 techniques: two 1.5-mm fully threaded bicortical screws using a lag technique, two 1.5-mm fully threaded bicortical nonlag screws, or 2 crossed 1.14-mm K-wires as a separate control. The fixation method was randomized for each of the 3 fractures per matched-pair hand, with each fixation being used in each hand and 8 total P1 fractures per fixation group. Hands were mounted to a custom frame where a computer-controlled, motor-driven, linear actuator powered movement of the flexor and extensor tendons. All fingers underwent 2,000 full flexion and extension cycles. Maximum interfragmentary displacement was continuously measured using a differential variable reluctance transducer. Our primary outcome was the difference in the mean P1 fragment displacement between lag and nonlag screw fixation at 2,000 cycles. RESULTS: The observed differences in mean displacement between lag and nonlag screw fixation were not statistically significant throughout all time points. A two one-sided test procedure for paired samples confirmed statistical equivalence in the fragment displacement between these fixation methods at all time points, including the primary end point of 2,000 cycles. CONCLUSIONS: Nonlag screws provided equivalent biomechanical stability to lag screws for simulated long oblique P1 fractures during cyclic testing in this cadaveric model. CLINICAL RELEVANCE: Fixation of long oblique P1 fractures with nonlag screws has the potential to simplify treatment without sacrificing fracture stability during immediate postoperative range of motion.

Social Adaptability Index and Pregnancy Outcomes in Women With Diabetes During Pregnancy.

OBJECTIVE: The social adaptability index (SAI) is a composite indicator capturing an individual's social adaptability within society and socioeconomic status to predict overall health outcomes. The objective of this analysis was to examine whether the SAI is an independent risk factor for adverse pregnancy outcomes in women with and without diabetes during pregnancy. METHODS: Data from the 2011-2017 National Survey of Family Growth were analyzed using a cross-sectional methodology. Women aged 18-44 years with a singleton gestation were included in the analysis. Maternal diabetes was defined as either presence of pregestational diabetes or diagnosis of gestational diabetes. The SAI was developed from the following maternal variables: educational level, employment status, income, marital status, and substance abuse. A higher score indicated lower risk. A series of multivariable logistic regression models were run stratified by maternal diabetes status to assess the association between SAI and pregnancy outcomes, including cesarean delivery, macrosomia (birth weight ≥4,000 g) and preterm birth (<37 weeks). All analyses were weighted and P <0.05 was considered significant. RESULTS: A total of 17,772 women were included in the analysis, with 1,965 (10.7%) having maternal diabetes during pregnancy. The SAI was lower in women with diabetes during pregnancy compared with control subjects (6.7 ± 0.2 vs. 7.2 ± 0.1, P <0.001). After adjusting for maternal race and ethnicity, insurance status, BMI, age, and partner support of the index pregnancy, SAI was associated with preterm birth among women with diabetes during pregnancy (adjusted odds ratio 0.83, 95% CI 0.72-0.94). The SAI was not significantly associated with cesarean delivery or macrosomia in women with diabetes during pregnancy and was not associated with these outcomes in women without diabetes during pregnancy. CONCLUSION: Among women with diabetes during pregnancy, a higher SAI is independently associated with a lower risk of preterm birth. The SAI could be a useful index to identify women at high risk of preterm birth in addition to traditionally defined demographic risk groups among women with diabetes during pregnancy.

Disparities Limit the Effect and Benefit of a Web-Based Clinic Intake System.

With increasing value being placed on patient-centered care and the focus on efficiency and workflow in health care delivery, the authors have implemented a web-based system for demographic, medical history, and patient-reported outcomes data collection for every clinical visit at their specialty upper-extremity center. They evaluated initial success and disparities in use after 12 months. The authors evaluated questionnaire parameters from 2018 patients, focusing primarily on the new patient intake form. They analyzed form-completion time relative to appointment time and form-completion percentage at various times before the appointment. The authors grouped patients by age, sex, race, income, education, employment status, transportation access, self-reported pain, and quality-of-life scores. Waiting room time was evaluated. Of new patients, 94% used the web-based platform to complete the intake form. Of the 4898 completed forms, 69.7% were done more than 1 hour before appointment time, indicating that a personal device was used. When grouped by patient characteristics and controlling for all demographic factors, patients who were male, non-White, and older than 40 years; had lower family income; and had a high school education or less were significantly associated with later form completion. Of the 1136 patients for whom the authors had adequate waiting room time data, late form completion significantly increased odds of waiting more than 15 minutes to be placed into an examination room. These data indicate that the authors are reliably capturing important patient information before appointment time. This could improve clinical workflow and overall quality of care and also identify limits in access and online system use, providing opportunities to improve capture by developing targeted interventions for specific patient populations.

Minimally Invasive Intramedullary Screw Versus Plate Fixation for Proximal Phalanx Fractures: A Biomechanical Study.

PURPOSE: To compare the maximum interfragmentary displacement of short oblique proximal phalanx (P1) fractures fixed with an intramedullary headless compression screw (IMHCS) versus a plate-and-screws construct in a cadaveric model that generates finger motion via the flexor and extensor tendons of the fingers. METHODS: We created a 30° oblique cut in 24 P1s of the index, middle, ring, and little fingers for 3 matched pairs of cadaveric hands. Twelve fractures were stabilized with an IMHCS using an antegrade, dorsal articular margin technique at the P1 base. The 12 matched-pair P1 fractures were stabilized with a radially placed 2.0-mm plate with 2 bicortical nonlocking screws on each side of the fracture. Hands were mounted to a frame allowing a computer-controlled, motor-driven, linear actuator powered movement of fingers via the flexor and extensor tendons. All fingers underwent 2,000 full-flexion and extension cycles. Maximum interfragmentary displacement was continuously measured using a differential variable reluctance transducer. RESULTS: The observed mean displacement differences between IMHCS and plate-and-screws fixation was not statistically significant throughout all time points during the 2,000 cycles. A 2 one-sided test procedure for paired samples confirmed statistical equivalence in fracture displacement between fixation methods at the final 2,000-cycle time point. CONCLUSIONS: The IMHCS provided biomechanical stability equivalent to plate-and-screws for short oblique P1 fractures at the 2,000-cycle mark in this cadaveric model. CLINICAL RELEVANCE: Short oblique P1 fracture fixation with an IMHCS may provide adequate stability to withstand immediate postoperative active range of motion therapy.

A Prospective Pilot Study of Vascular Assessment of the Upper Extremity With Laser Angiography.

Background: Our goal was to investigate patients' upper extremity tissue perfusion changes using an indocyanine green laser angiography imaging system for various pathologic states and interventions. Methods: This prospective observational study used Spy Elite/LUNA laser angiography to evaluate perfusion in patients with upper extremity vascular compromise. All patients had Spy Elite/LUNA imaging as well as clinical and handheld Doppler examinations preintervention, intraoperatively, if applicable, and at 1 week, 2 weeks, and 2 months postintervention. For each laser angiography scan, we used an unaffected control area with uninjured skin to quantitatively compare with the dysvascular tissues. Results: Twelve patients, 7 men and 5 women, had a total of 16 upper extremities evaluated. The mean age was 53 years, and half of the patients entering the study were smokers. Etiologies of vascular compromise were trauma, primary and secondary vasospastic disease, scleroderma, and intravascular drug injection. Interventions included surgical repair/reconstruction, botulinum toxin injections, and/or systemic medications. Improvement in perfusion following intervention was statistically significant, demonstrated by an increase in Spy Elite/LUNA quantitative score postintervention compared with preintervention scans. Adjusting for other variables, such as smoking and handheld Doppler signal status, demonstrated an independent statistically significant increase in Spy Elite/LUNA scores at all postintervention time points compared with preintervention scores. Laser angiography was able to confirm adequate vascular status, with ultimate tissue survival, in some cases when Doppler signals were not initially present. Conclusions: Laser angiography provided objective data to document improved upper extremity tissue perfusion following various interventions.

Adolescents' and Young Adults' Routine Care Use: The Role of Their Mothers' Care Use Behaviors.

PURPOSE: Little is known whether mothers' own care use is differentially associated with their adolescents' routine care use by gender. The main purpose of this study is to examine whether mothers' healthcare use prospectively predicts their adolescents' routine care use stratified by gender, after controlling for predisposing (child's age, race/ethnicity, region of residence, urbanicity, and mother's age at child's birth), enabling (mother's education, adolescent and mother health insurance), and need (child health status) factors. METHODS: In 2018, a prospective analysis was conducted using data from 5,040 adolescents aged 9-24 and their mothers who completed the two-generation National Longitudinal Survey of Youth in 2006 (first interview) and 2008 (second interview). Findings include percentages and adjusted odds ratios of the factors that predict adolescents' self-report of routine care use in the past year measured at the second interview. RESULTS: In 2008, over half of participants reported a routine doctor visit during the prior 12 months and this varied by gender; more females (68.7%) had a visit than males (53.5%). Factors that independently predicted a greater odds of adolescents' routine doctor visits included mothers with routine doctor visits at both interviews or the second interview only, and adolescents' health insurance and past routine visit, regardless of gender. Males aged 18-20 and 21-24 years had lower odds of having a routine doctor visit than males aged 9-11 years. CONCLUSIONS: This study provides evidence for the potential role that mothers' care use can play in their adolescents' routine care use, especially for their sons, independent of insurance status.
