RESUMEN
Background: During the COVID-19 pandemic, telemedicine plays a critical role in providing safe, effective healthcare services, while reinforcing social distancing and optimizing the use of personal protective equipment. In this context, the Oklahoma Children's Hospital implemented virtual neonatology prenatal visits for pregnant women with a diagnosis of fetal anomalies. While tele-consultations have been broadly used with a high degree of acceptance in rural and remote areas, satisfaction has not been assessed in this particular scenario, where patients and physicians discussing sensitive healthcare information had to rapidly adjust to this new modality. Objectives: To evaluate patients' and neonatologists' satisfaction with virtual prenatal consultations in the context of the COVID-19 pandemic and to compare satisfaction levels of patients receiving virtual consultation with those receiving in-person consults. Methods: This cross-sectional study evaluated patients' and neonatologists' satisfaction with virtual consultations. Participants included pregnant women with diagnosis of fetal anomalies who received neonatology prenatal consultations at Oklahoma Children's Hospital, either in-person or through telemedicine, from May to mid-November 2020, and neonatologists providing virtual prenatal consultations in the same period. Virtual visits were delivered via Zoom Pro™. Patients and physicians who agreed to participate rated acceptability completing an anonymous 5-point Likert scale survey. Item frequencies and means for categories of items were computed by group (video-consult patients, in-person patients, physicians) and analyzed, using Welch's t for unequal sample size. Results: Overall consultation quality was rated good or excellent by 35 (100%) video-consult patients and 12 (100%) in-person patients. Patient group means computed on six 5-point Likert items about patient-physician communication did not differ significantly, video-consult: M = 28.71 (2.22); in-person consult: M = 28.92 (1.78) (p = 0.753263). All eight physicians (100%) agreed or strongly agreed that telemedicine was effective, using a 5-point Likert scale, and their combined consultation quality score computed on 10 survey questions was high: M = 46.4 (3.11). Conclusion: Despite patient inexperience with tele-consultations, the quick implementation of telemedicine, and the sensitive reason for the visit, patients and physicians were highly satisfied with virtual visits. Telemedicine is a safe, effective alternative for providing neonatology prenatal consultations for pregnant women with diagnosis of fetal anomalies during the pandemic.
RESUMEN
PREMISE OF THE STUDY: Characteristics of rare taxa include small population sizes and limited geographical ranges. The genetic consequences of rarity are poorly understood for most taxa. A small geographical range could result in reduced opportunity for isolation by distance or environment, thereby limiting genetic structure and variation, but few studies explore genetic structure at small spatial scales with sufficient resolution to test this hypothesis. Moreover, few comparative genetic studies exist among infrataxa differing in rarity. Here, we compare genetic variation among varieties of Astragalus lentiginosus differing in range size. Additionally, we ask if genetic structure exists in A. lentiginosus var. piscinensis, a rare taxon consisting of several thousand individuals that persist on ~8 km2 of alkaline soil. METHODS: We compared genetic variation among 11 varieties of A. lentiginosus differing in range size using a genotyping by sequencing (GBS) approach, which generated 11,475 single nucleotide polymorphisms (SNPs). We characterized genetic structure among subpopulations of A. lentiginosus var. piscinensis using a second GBS data set of 7274 SNPs and explored associations between genetic structure and environmental variation. KEY RESULTS: We found no association between genetic variation and range size among varieties of A. lentiginosus. Additionally, despite the extremely small range of A. lentiginosus var. piscinensis, we report a well-defined genetic structure among subpopulations associated with microhabitat variation in soil composition. CONCLUSIONS: Our results suggest that fine scale genetic structure may exist within other rare Astragalus taxa and that rarity does not preclude the maintenance of genetic diversity in this genus.

Effects observed within one generation disregard potential detrimental effects that may appear across generations. Previously we have developed a two generation Daphnia magna reproduction test using the OECD TG 211 protocol with a few amendments, including initiating the second generation with third brood neonates produced from first generation individuals. Here we showed the results of an inter-laboratory calibration exercise among 12 partners that aimed to test the robustness and consistency of a two generation Daphnia magna reproduction test. Pyperonyl butoxide (PBO) was used as a test compound. Following experiments, PBO residues were determined by TQD-LC/MS/MS. Chemical analysis denoted minor deviations of measured PBO concentrations in freshly prepared and old test solutions and between real and nominal concentrations in all labs. Other test conditions (water, food, D. magna clone, type of test vessel) varied across partners as allowed in the OECD test guidelines. Cumulative fecundity and intrinsic population growth rates (r) were used to estimate "No observed effect concentrations "NOEC using the solvent control as the control treatment. EC10 and EC-50 values were obtained regression analyses. Eleven of the twelve labs succeeded in meeting the OECD criteria of producing >60 offspring per female in control treatments during 21days in each of the two consecutive generations. Analysis of variance partitioning of cumulative fecundity indicated a relatively good performance of most labs with most of the variance accounted for by PBO (56.4%) and PBO by interlaboratory interactions (20.2%), with multigenerational effects within and across PBO concentrations explaining about 6% of the variance. EC50 values for reproduction and population growth rates were on average 16.6 and 20.8% lower among second generation individuals, respectively. In summary these results suggest that the proposed assay is reproducible but cumulative toxicity in the second generation cannot reliably be detected with this assay.
