RESUMO
INTRODUCTION: Pharmacy students share a prevailing sense of stress. Many methods to increase student wellness are pharmacy program specific and faculty driven. This commentary is a call to action for student pharmacists to take shared ownership over improving the current crisis of student well-being. Schools of pharmacy should empower their students to guide the improvement of student wellness. Student-led wellness initiatives can take many forms; this commentary will focus on a student-led walking group as means to bolster wellness within a school of pharmacy. PERSPECTIVE: Exercise activities promote school-life balance, and when initiated by peers, will naturally conform to their schedule and develop collegial support through socialization. Student pharmacists should begin with encouraging peers to engage in exercise as a positive coping mechanism. Students should lead their peers in developing activities and electronic device sharing to encourage socialization and positive coping mechanisms. IMPLICATIONS: While many efforts are in place for faculty and schools of pharmacy to improve student well-being, little has been studied on the impact of student-led wellness programs. This article calls student pharmacists to take shared ownership over the student wellness crisis and find ways to intervene. Schools of pharmacy should empower students by providing supportive structures while allowing students to problem-solve and practice wellness themselves.

Single source and multiple donor (mixed) samples of human mitochondrial DNA were analyzed and compared using the MinION and the MiSeq platforms. A generalized variant detection strategy was employed to provide a cursory framework for evaluating the reliability and accuracy of mitochondrial sequences produced by the MinION. The feasibility of long-read phasing was investigated to establish its efficacy in quantitatively distinguishing and deconvolving individuals in a mixture. Finally, a proof-of-concept was demonstrated by integrating both platforms in a hybrid assembly that leverages solely mixture data to accurately reconstruct full mitochondrial genomes.

BACKGROUND: The MinION™ nanopore sequencer was recently released to a community of alpha-testers for evaluation using a variety of sequencing applications. Recent reports have tested the ability of the MinION™ to act as a whole genome sequencer and have demonstrated that nanopore sequencing has tremendous potential utility. However, the current nanopore technology still has limitations with respect to error-rate, and this is problematic when attempting to assemble whole genomes without secondary rounds of sequencing to correct errors. In this study, we tested the ability of the MinION™ nanopore sequencer to accurately identify and differentiate bacterial and viral samples via directed sequencing of characteristic genes shared broadly across a target clade. RESULTS: Using a 6 hour sequencing run time, sufficient data were generated to identify an E. coli sample down to the species level from 16S rDNA amplicons. Three poxviruses (cowpox, vaccinia-MVA, and vaccinia-Lister) were identified and differentiated down to the strain level, despite over 98% identity between the vaccinia strains. The ability to differentiate strains by amplicon sequencing on the MinION™ was accomplished despite an observed per-base error rate of approximately 30%. CONCLUSIONS: While nanopore sequencing, using the MinION™ platform from Oxford Nanopore in particular, continues to mature into a commercially available technology, practical uses are sought for the current versions of the technology. This study offers evidence of the utility of amplicon sequencing by demonstrating that the current versions of MinION™ technology can accurately identify and differentiate both viral and bacterial species present within biological samples via amplicon sequencing.

Repeated daily dosing of mice with 4-vinylcyclohexene diepoxide (VCD) causes a gradual onset of ovarian failure, providing a model for perimenopause. Because increasing numbers of women are delaying starting a family, infertility in aging women is of concern. This study was designed to determine the effects of impending ovarian failure on fertility in VCD-treated mice. Female C57BL/6J mice were dosed daily (17 d) with vehicle control or VCD (160 mg/kg, intraperitoneally) to deplete primordial follicles and then were divided into 2 groups. Group 1 was mated soon after dosing; group 2 was mated on day 20 after dosing, during impending ovarian failure. Fertility was evaluated on gestational day 16. In group 1, cycle length, pregnancy rate, and number of live fetuses did not differ between VCD-treated animals and controls, but VCD-treated mice required more matings to become pregnant and had more resorptions. In group 2, VCD-treated mice demonstrated proestrus and copulatory plugs, but only 1 animal became pregnant, and she had no viable fetuses. Ovaries from pregnant and nonpregnant controls contained similar numbers of follicles and corpora lutea. Ovaries from VCD-treated animals contained no follicles, and corpora lutea were seen only in pregnant animals. In VCD-treated mice mated soon after dosing, conception was more difficult and more resorbed fetuses were seen, whereas in those mated closer to impending ovarian failure, no successful pregnancies were achieved. These results demonstrate that VCD-treated mice can be used to model infertility in perimenopausal women.
