The objective of this study was to evaluate the perception of the initial ASRM COVID-19 recommendations for infertility treatment held by women's health providers within varying subspecialties, as well as their attitudes toward pregnancy and fertility during this time.

An electronic survey was sent to all women's healthcare providers, including physicians, mid-level providers and nurses, in all subspecialties of obstetrics and gynaecology (Ob/Gyn) at a large tertiary care university-affiliated hospital.

Of the 278 eligible providers, the survey response rate was 45% (n= 127). Participants represented 8 Ob/Gyn subspecialties and all professional levels. Participants age 18-30years were significantly more likely to feel that women should have access to infertility treatment despite the burden level of COVID-19 in respective community/states (p= 0.0058). Participants within the subspecialties of general Ob/Gyn, maternal foetal medicine and gynecologic oncology were significantly more likely to disagree that all women should refrain from planned conception during the COVID-19 pandemic, in comparison to those in urogynecology and reproductive endocrinology and infertility (p= 0.0003).

Considering the immediate and unknown long-term impact of the COVID-19 pandemic on fertility care delivery, a better understanding of perceptions regarding infertility management during this time is important. Our study shows overall support for the initial ASRM recommendations, representing a wide spectrum of women's health providers.

Geographic disparities for assisted reproductive technology (ART) continue to exist. Travel cost and time off work may create additional barriers for patients living remotely. Implementing telehealth can alleviate these barriers by reducing office visits. The aim of this study was to evaluate patient satisfaction with telehealth during ART.

This was a cross-sectional survey and retrospective cohort study. Patients living remotely who underwent ART utilizing telehealth between 2015 and 2018 at a single institution were selected for the telehealth group. The non-telehealth control group included randomly selected patients who underwent IVF at the same institution between 2015 and 2018. Demographic variables and treatment outcomes were obtained for both groups. A patient satisfaction questionnaire was distributed to telehealth patients. Statistical analysis using χ

test was performed to compare ART outcomes between both groups.

Ninety-seven control and 97 telehealth patients were included. For telehealth patients, the mean number of office visits and distance traveled was 2.9 (± 0.8 SD) and 143.1 miles (± 49.2 SD) respectively. 58.8% of patients completed the survey. 44/57 participants had an oocyte retrieval and 42/44 underwent embryo transfer. For those who completed the survey, the clinical pregnancy rate was 31/44 and the live birth rate was 25/44. There was no difference in treatment outcomes between telehealth compared to controls. 73% of patients were highly satisfied with telehealth.

Telehealth can improve access to ART in underserved areas and results in high patient satisfaction. Reproductive health providers could consider telehealth as a safe and efficacious tool to ameliorate geographic disparities.

In cultivated tomato (Solanum lycopersicum) glandular trichomes accumulate a blend of abundant monoterpenes and smaller amounts of a few sesquiterpenes. These mono- and sesquiterpenes are synthesized by three terpene synthases, TPS20 as well as TPS9 and TPS12, respectively. Navarixin To study effects of these terpenes on performance and choice behavior of potato aphid (Macrosiphum euphorbiae), we utilized two tomato trichome mutants, hairless and odorless-2, that are differently affected in mono- and sesquiterpene production. Non-choice assays demonstrated that longevity and fecundity of M. euphorbiae were increased when kept on the trichome mutants. A principal component analysis of these aphid performance parameters and terpene production in the trichome mutants indicated that longevity and fecundity of M. euphorbiae were negatively correlated with production of the TPS12-derived sesquiterpenes β-caryophyllene and α-humulene. While we had previously shown that addition of pure β-caryophyllene/α-humulene to an artificial feeding diet affected M. euphorbiae apterae survivorship and feeding behavior, no such effects were observed here upon addition of a mixture of pure TPS20-derived monoterpenes. In olfactometer assays M. euphorbiae alates displayed differential choice behaviors towards the hairless and odorless-2 mutants suggesting a role of TPS20-derived monoterpenes in aphid attraction, which was further confirmed using a mixture of pure monoterpenes. Our analyses revealed contrasting roles of glandular trichome-derived terpenes in S. lycopersicum. While TPS12-derived sesquiterpenes contribute to host plant resistance against M. euphorbiae, TPS20-derived monoterpenes appear to be exploited as cue for host plant orientation by aphids.

Lower respiratory tract infections are common in adult patients with cystic fibrosis (CF) and are frequently caused by Pseudomonas aeruginosa, resulting in chronic lung inflammation and fibrosis. The progression of multidrug-resistant strains of P. aeruginosa and alterations in the pharmacokinetics of many antibiotics in CF make optimal antimicrobial therapy a challenge, as reflected by high between- and inter-individual variability (IIV).

This review provides a synthesis of population pharmacokinetic models for various antibiotics prescribed in adult CF patients, and aims at identifying the most reported structural models, covariates and sources of variability influencing the dose-concentration relationship.

A literature search was conducted using the PubMed database, from inception to August 2020, and articles were retained if they met the inclusion/exclusion criteria.

A total of 19 articles were included in this review. One-, two- and three-compartment models were reported to best describe the pharmacokinetics of various antibiotics.
