RESUMO

BACKGROUND: Some users of the etonogestrel contraceptive implant experience bothersome bleeding, which can reduce contraceptive satisfaction and continuation. Few strategies exist to manage this bleeding. The exact mechanism of progestin-induced bleeding is unknown, but it is likely multifactorial (eg, impaired angiogenesis, "leaky" fragile vasculature, and inflammation). Curcumin, the active ingredient in turmeric, has anti-inflammatory, antiproliferative, and antiangiogenic properties, which may make it a useful agent for implant-associated bothersome bleeding. OBJECTIVE: This study aimed to evaluate whether curcumin decreases frequent or prolonged bleeding or spotting in contraceptive implant users. STUDY DESIGN: The study was a randomized, double-blind, placebo-controlled trial. Here, etonogestrel implant users with frequent or prolonged bleeding or spotting were enrolled and randomized to either 600-mg Theracurmin HP (Immunovites, Las Vegas, NV) or placebo daily for 30 days. The term "frequent" was defined as ≥2 independent bleeding or spotting episodes, and the term "prolonged" was defined as ≥7 consecutive days of bleeding or spotting in a 30-day interval. Implant use was confirmed by clinical examination and negative gonorrhea and chlamydia and pregnancy tests. Enrolled participants initiated study treatment after 3 consecutive days of bleeding or spotting; if no bleeding or spotting occurred within 30 days of enrollment, the participants were withdrawn from the study. Study treatments were encapsulated to maintain a similar appearance. Participants used text messages to record daily bleeding patterns and study drug compliance. Bleeding was defined as a day that required the use of protection with a pad, tampon, or liner, and spotting was defined as a day with minimal blood loss that did not require the use of any protection. Our primary outcome was the total number of days without bleeding or spotting during the 30 days of study drug or placebo exposure. The secondary outcomes included total number of bleeding-free days, bleeding episodes, and satisfaction. A sample size of 22 per group provided 80% power at an alpha level of .05 to demonstrate a 6-day difference between groups. RESULTS: From February 2021 to November 2022, 58 individuals enrolled in the study with 54 participants (93%) completing 30 days of treatment (26 in the curcumin group and 28 in the placebo group). Of note, 1 individual in the curcumin arm did not experience a qualifying bleeding event and, thus, never initiated treatment and, per protocol, was withdrawn from the study. Participant characteristics did not differ between groups, including length of implant use at study enrollment (placebo, 521±305 days; curcumin, 419±264 days). The study groups did not differ concerning any bleeding-related outcome (mean days without bleeding or spotting: curcumin, 16.7±6.9; placebo, 17.5±4.8; P=.62; mean bleeding-free days: curcumin, 23.4±4.9; placebo, 22.4±4.5; P=.44; bleeding episodes: curcumin, 2.0±0.8; placebo, 2.1±0.8; P=.63). In addition, satisfaction with the implant as contraception and acceptability of bleeding over the study period did not differ by study group (P=.54 and P=.30, respectively). CONCLUSION: Daily use of curcumin did not improve bleeding patterns in users of the etonogestrel contraceptive implant experiencing frequent or prolonged bleeding patterns.

RESUMO

Background: Long-term outcomes of preterm infants fed an exclusive human milk-based (EHM) diet using a donor human milk-based fortifier are not well defined. Materials and Methods: Infants ≤1,250 g birth weight (BW) were studied prospectively at two outpatient visits: 12-15 and 18-22 months corrected age (CA). Dual-energy X-ray absorptiometry and Bayley Scales of Infant and Toddler Development III (BSID-III) were performed at 18-22 months CA. Results: In this pilot study, 51 preterm infants (gestational age 27.8 ± 2.6 weeks and BW 893 ± 204 g) were evaluated. While anthropometric z-scores were significantly lower at discharge compared with birth, z-scores returned to birth levels by 12-15 months CA (length and head circumference [HC]) and 18-22 months CA (weight). Body composition at 2 years of age was similar to term-matched controls. Inpatient growth was significantly correlated with bone density, lean mass (LM), and fat-free mass at 18-22 months CA. Increased mother's own milk (MOM) was significantly correlated with decreased fat mass indices. BSID-III showed that 0% of cognitive composite scores were <70. Conclusions: In addition to returning to BW, length, and HC z-scores by 2 years of age, body composition analysis revealed that increase in body size was appropriate as reflected by LM and bone density similar to matched term controls without an increase in fat mass. No child had severe cognitive developmental delay using a cutoff score of 70. Inpatient growth and increased receipt of MOM correlated with favorable growth and body composition outcomes. Positive outcomes as shown in this study to confirm postdischarge safety of an EHM diet during hospitalization.

RESUMO

OBJECTIVE: To evaluate the hypothesis that feeding volumes exceeding 100 mL/kg/d and exposure to cow's milk formula preoperatively increase the risk for preoperative necrotizing enterocolitis (NEC) in infants with complex congenital heart disease. STUDY DESIGN: All infants, of any gestational age, with an isolated cardiac lesion at high risk for NEC (ductal-dependent lesions, transposition of the great arteries, truncus arteriosus, and aorto-pulmonary window) admitted to Texas Children's Hospital from 2010 to 2016 were included. NEC was defined based on the modified Bell criteria. Feeding regimen information and relevant covariates were collected. Logistic regression was used to evaluate the association of feeding regimen and other potential risk factors with NEC. RESULTS: In this single-center, retrospective cohort of 546 infants, 3.3% developed Bell stage I-III NEC preoperatively. An exclusive unfortified human milk diet was associated with a significantly lower risk of preoperative NEC (OR 0.17, 95% CI 0.04-0.84, P = .03) in a multivariable regression model controlling for cardiac lesion, race, feeding volume, birth weight small for gestational age, inotrope use presurgery/pre-NEC, and prematurity. Feeding volumes exceeding 100 mL/kg/d were associated with a significantly greater risk of preoperative NEC (OR 3.05, 95% CI 1.19-7.90, P = .02). CONCLUSIONS: The findings suggest that an unfortified exclusive human milk diet may reduce the risk of preoperative NEC in infants with complex congenital heart disease.

RESUMO

BACKGROUND: Mother's own milk (MOM) is protective against gut microbiota alterations associated with necrotizing enterocolitis (NEC) and feeding intolerance among preterm infants. It is unclear whether this benefit is preserved with donor milk (DM) feeding. OBJECTIVE: We aimed to compare microbiota development, growth, and feeding tolerance in very-low-birth-weight (VLBW) infants fed an exclusively human milk diet of primarily MOM or DM. METHODS: One hundred and twenty-five VLBW infants born at Texas Children's Hospital were enrolled and grouped into cohorts based on percentage of MOM and DM in enteral feeds. Feeds were fortified with DM-derived fortifier per unit protocol. Weekly stool samples were collected for 6 wk for microbiota analysis [16S ribosomal RNA (rRNA) sequencing]. A research nurse obtained weekly anthropometrics. Clinical outcomes were compared via Wilcoxon's rank-sum test and Fisher's exact test, as well as multivariate analysis. RESULTS: The DM cohort (n = 43) received on average 14% mothers' milk compared with 91% for the MOM cohort (n = 74). Diversity of gut microbiota across all time points (n = 546) combined was increased in MOM infants (P < 0.001). By 4 and 6 wk of life, microbiota in MOM infants contained increased abundance of Bifidobacterium (P = 0.02) and Bacteroides (P = 0.04), whereas DM-fed infants had increased abundance of Staphylococcus (P = 0.02). MOM-fed infants experienced a 60% reduction in feeding intolerance (P = 0.03 by multivariate analysis) compared with DM-fed infants. MOM-fed infants had greater weight gain than DM-fed infants. CONCLUSIONS: Compared with DM-fed infants, MOM-fed infants have increased gut microbial community diversity at the phylum and genus levels by 4 and 6 wk of life, as well as better feeding tolerance. MOM-fed infants had superior growth. The incidence of NEC and other gastrointestinal morbidity is low among VLBW infants fed an exclusively human milk diet including DM-derived fortifier. This trial was registered at clinicaltrials.gov as NCT02573779.

RESUMO

OBJECTIVE: To determine if a combined oral contraceptive (COC) initiated shortly after ulipristal acetate (UPA) administration interferes with its mechanism of action. STUDY DESIGN: Healthy, reproductive-age women of normal BMI with proven ovulation (serum progesterone >3 ng/ml) were enrolled for three cycles (Cycle 1, UPA only; Cycle 2 washout; Cycle 3 UPA plus COC). During Cycles 1 and 3, subjects were monitored with transvaginal ultrasound and blood sampling for progesterone and LH every other day until a dominant follicle measuring >15 mm was visualized. In both treatment cycles, subjects received UPA (30mg) and were followed daily with similar monitoring for up to 7 days. In Cycle 3 only, subjects initiated a daily COC (0.15 mg levonorgestrel/30 µg ethinyl estradiol) 2 days after UPA. The study had 80% power to detect a 15% difference in the proportion of cycles with at least a 5-day delay in follicle rupture. We assessed follicle rupture as >50% decrease in mean size and adjudicated unclear outcomes with serum hormones. RESULTS: A total of 36 women enrolled and 33 completed all study procedures [age 28.4 years (SD 3.9); BMI 23.4 (SD 2.4)]. Compared to Cycle 1, more subjects demonstrated evidence of follicle rupture in <5 days in Cycle 3 [1/33 (3%) vs. 9/33 (27%), p = .008]. We also included data from 2 subjects who experienced rupture prior to COC dosing in the analysis. CONCLUSION: UPA's effectiveness is significantly reduced by administering COCs 2 days later. IMPLICATIONS: This study demonstrates that UPA's efficacy as an emergency contraceptive is reduced with early exposure to COCs.

RESUMO

OBJECTIVE: The aim of this study was to compare outcomes of infants pre and post initiation of a feeding protocol providing an exclusive human milk-based diet (HUM). MATERIALS AND METHODS: In a multicenter retrospective cohort study, infants with a birth weight <1,250 g who received a bovine-based diet (BOV) of mother's own milk fortified with bovine fortifier and/or preterm formula were compared to infants who received a newly introduced HUM feeding protocol. Infants were excluded if they had major congenital anomalies or died in the first 12 hours of life. Data were collected 2-3 years prior to and after introduction of an exclusive HUM diet. Primary outcomes were necrotizing enterocolitis (NEC) and mortality. Secondary outcomes included late-onset sepsis, retinopathy of prematurity (ROP), and bronchopulmonary dysplasia (BPD). RESULTS: A total of 1,587 infants were included from four centers in Texas, Illinois, Florida, and California. There were no differences in baseline demographics or growth of infants. The HUM group had significantly lower incidence of proven NEC (16.7% versus 6.9%, p < 0.00001), mortality (17.2% versus 13.6%, p = 0.04), late-onset sepsis (30.3% versus 19.0%, p < 0.00001), ROP (9% versus 5.2%, p = 0.003), and BPD (56.3% versus 47.7%, p = 0.0015) compared with the BOV group. CONCLUSIONS: Extremely premature infants who received an exclusive HUM diet had a significantly lower incidence of NEC and mortality. The HUM group also had a reduction in late-onset sepsis, BPD, and ROP. This multicenter study further emphasizes the many benefits of an exclusive HUM diet, and demonstrates multiple improved outcomes after implementation of such a feeding protocol.

RESUMO

OBJECTIVES: To confirm that measuring pregnancy-associated plasma protein-A (PAPP-A) in both first- and second-trimester serum samples improves Down syndrome screening. METHODS: We selected paired first- and second-trimester stored serum samples from 34 Down syndrome pregnancies (cases) and 514 unaffected pregnancies (controls) and tested the second-trimester samples for PAPP-A and dimeric inhibin-A (DIA). First-trimester PAPP-A measurements were already available, as were second-trimester measurements of alpha-fetoprotein, unconjugated estriol (uE3), and human chorionic gonadotrophin (hCG). RESULTS: PAPP-A was lower among cases than controls (0.47 MoM) in the first trimester (at an average of 12.5 weeks); in the second trimester, it was not different (0.91 MoM). Using repeated measures of PAPP-A alone, 21 of 34 cases were detected (62%, 95%CI 44% to 78%) with 5% false positives. At an observed 2% false-positive rate, the detection rates (DR) for the quadruple (69%) and serum integrated (69%) tests were lower than for the repeated measures test (75%). Modelled performance at 12 weeks was similar to these observed findings (70, 75, and 82%, respectively). If the first-trimester samples were collected at 10 weeks, however, DR would be higher (70, 81, and 91%, respectively). CONCLUSIONS: Adding a repeated measure of PAPP-A to existing serum markers improves Down syndrome screening to levels that are currently obtainable only by including ultrasound measurement of nuchal translucency (NT). Serum-based screening has the advantages of higher availability and reliability at a lower cost, resulting in a more effective screening strategy. A serum-based repeated measures test has a place in routine Down syndrome screening.
