Study design We compared laboratory indices of 151 samples obtained from 139 different individual patients with negative, borderline, or positive EMA-test results. We also compared the clinical data of the patients in each EMA test results group. Results Borderline EMA-test results were obtained for 13 patients and were associated with more severe anemia, and lower reticulocyte count and reticulocyte production index compared with samples with positive EMA-test results. A receiving operator characteristic analysis identified mean corpuscular hemoglobin concentration of <32.5 g/dL as a cut-off, between positive/borderline and negative test results with 100% sensitivity. A higher prevalence of clinical markers typical of hereditary spherocytosis was found in patients with borderline or positive compared with negative EMA test samples. Conclusions Based on laboratory data, borderline EMA-test results may be an indication of a more severe form of hereditary spherocytosis. Using mean corpuscular hemoglobin concentration as a cut-off may help predict and reduce negative EMA tests without compromising sensitivity. This finding needs to be further validated in other flow cytometry laboratories with a large EMA test sample pool.

Study design We included 500 children aged 2-72 months with a history of UTI who were followed prospectively for approximately 2 years in the context of 2 previously conducted studies (Randomized Intervention for Children with Vesicoureteral Reflux and Careful Urinary Tract Infection Evaluation). We identified significant risk factors for febrile recurrences among children not receiving antimicrobial prophylaxis using univariate and multivariate logistic regression. Result On univariate analysis, non-Black race, febrile index UTI, bowel-bladder dysfunction, grade IV vesicoureteral reflux, renal scarring at baseline, and renal-bladder ultrasound abnormalities were associated with febrile recurrence. On multivariate analysis, the following variables independently increased the odds of febrile recurrences (OR; 95% CI): non-Black race (7.1; 1.5-127.9), bowel-bladder dysfunction (2.6; 1.1-5.3), febrile index UTI (2.5; 1.1-6.9), abnormalities on renal-bladder ultrasound scan (2.6; 1.2-5.6), grade IV vesicoureteral reflux (3.9; 1.4-10.5), and renal scarring at baseline (4.7; 1.2-19.1). Conclusions Non-Black race and grade IV vesicoureteral reflux increased the odds of febrile recurrence of UTI. Although our findings should stimulate other studies to further explore the relationship between race and UTIs, given that the link between race and UTI recurrence is unclear, race should not be used to make decisions regarding management of children with a UTI.

Study design LARC insertion data (682 implants and 681 intrauterine devices [IUDs]) were prospectively collected from January 1, 2017, through December 31, 2019, across 3 Adolescent Medicine practices. Followup data through December 31, 2020, were included to ensure at least 1 year of follow-up of this cohort. Continuation rates were calculated at 1, 2, and 3 years, overall and by Adolescent Medicine site, as were descriptive statistics for LARC procedural complications and patient experience. Results Implant and IUD insertion complications were uncommon and largely self-limited, with no IUD-related uterine perforations. Uterine bleeding was the most frequently reported concern at follow-up (35% implant, 25% IUD), and a common reason for early device removal (45% of implant removals, 32% of IUD removals). IUD malposition or expulsion occurred following 6% of all insertions. The pooled implant continuation rate at 1 year was 87% (range, 86%-91 % across sites; P = .63), 66% at 2 years (range, 62%-84%; P = .01), and 42% at 3 years (range, 36%-60%; P = .004). The pooled IUD continuation rate at 1 year was 88% (range, 87%-90% across sites; P = .82), 77% at 2 years (range, 76%-78%; P = .94), and 60% at 3 years (range, 57%-62%; P = .88). Conclusions LARC is successfully provided in Adolescent Medicine clinical settings, with continuation rates analogous to those of well-resourced clinical trials. Uterine bleeding after LARC insertion is common, making counselling imperative. Future analyses will assess whether the medical management of LARC-related nuisance bleeding improves continuation rates in our Adolescent Medicine patient population.

Study design This was a prospective observational cohort study evaluating arterial blood gas (ABG) samples and ventilator support in 34 infants with CDH in the first hour of life. Infants were stratified into mild, moderate, and severe CDH. The first ABG was compared with the umbilical cord ABGs and response to intervention evaluated on subsequent ABGs among infants with different CDH severities. Results Infants were intubated at a median of 120 seconds (range 50-240 seconds) and ABGs obtained at a median of 6 minutes (IQR 4, 8 minutes), 16 minutes (IQR 13.5, 22.5 minutes), and 60 minutes (IQR 56, 64 minutes). Compared with the cord ABG, first ABG mean partial pressure of carbon dioxide (PaCO2) increased from 49.8 mm Hg to 82.1 mm Hg, mean base deficit decreased from -2.2 to -7.3, and mean pH from 7.298 to 7.060. With ventilator adjustments, second mean PaCO2 decreased to 76.7 mm Hg and third mean PaCO2 48.5 mm Hg. When stratified, with all CDH seventies PaCO2 increased abruptly, remained elevated in moderate and severe CDH, and improved in all severities by 60 minutes after delivery. Conclusions Gas exchange is markedly altered in the first hour of life in infants with CDH with abrupt onset of acidemia and a mixed respiratory and metabolic acidosis. Early implementation of adequate cardiopulmonary support may contribute to more timely stabilization of gas exchange.
