RESUMEN
IMPORTANCE: It is well known that influenza A viruses (IAV) initiate host cell infection by binding to sialic acid, a sugar molecule present at the ends of various sugar chains called glycoconjugates. These sugar chains can vary in chain length, structure, and composition. However, it remains unknown if IAV strains preferentially bind to sialic acid on specific glycoconjugate type(s) for host cell infection. Here, we utilized CRISPR gene editing to abolish sialic acid on different glycoconjugate types in human lung cells, and evaluated human versus avian IAV infections. Our studies show that both human and avian IAV strains can infect human lung cells by utilizing any of the three major sialic acid-containing glycoconjugate types, specifically N-glycans, O-glycans, and glycolipids. Interestingly, simultaneous elimination of sialic acid on all three major glycoconjugate types in human lung cells dramatically decreased human IAV infection, yet had little effect on avian IAV infection. These studies show that avian IAV strains effectively utilize other less prevalent glycoconjugates for infection, whereas human IAV strains rely on a limited repertoire of glycoconjugate types. The remarkable ability of avian IAV strains to utilize diverse glycoconjugate types may allow for easy transmission into new host species.

Objective: To solicit Illinois staff and clinician perspectives on rapid implementation of telehealth for contraceptive counseling and recommendations to improve and sustain it in the long term. Study design: Researchers recruited and interviewed clinicians (n = 20) in primary care and obstetrics/gynecology clinics across 13 health care systems in Illinois, as well as clinicians (n = 11), leadership (n = 6) and staff (n = 7) from Planned Parenthood of Illinois clinics. Guided by the Consolidated Framework for Implementation Research, we coded and analyzed interview transcripts in Dedoose with a focus on themes regarding steps to improve quality and sustainability of telehealth. Results: Participants expressed generally positive attitudes towards telehealth, noting that it increased access to care and time for patient education. Still, many highlighted areas of implementation that needed improvement. Clinic operations were complicated by gaps in telehealth training and the logistical needs of balancing telehealth and in-person appointments. Clinics had difficulty ensuring patient awareness of telehealth as an option for care, in addition to deficiencies with the telehealth technology itself. Finally, innovative resources for telehealth patients, while existent, have not been evenly offered across clinics. This includes the use of self-injection birth control, as well as providing medical equipment such as blood pressure cuffs in community settings. Some themes reflect issues specific to contraceptive counseling while others reflect issues with telehealth implementation in general, including confusion about reimbursement. Conclusion: Illinois contraceptive care providers and staff wish to sustain telehealth for the long term, while also recommending specific improvements to patient communications, clinic operations, and access to supportive resources. Implications: Our study highlights considerations for clinics to optimize implementation of telehealth services for contraceptive care. Providers described the value of clear workflows to balance in-person and telehealth visits, streamlined communications platforms, targeted patient outreach, training on providing virtual contraceptive care, and creative approaches to ensuring patient access to resources.
RESUMEN
CONTEXT: The COVID-19 pandemic increased the provision of contraception through telemedicine. This qualitative study describes provider perceptions of how telemedicine provision of contraception has impacted patient care. METHODS: We interviewed 40 obstetrics-gynecology and family medicine physicians, midwives, nurse practitioners, and support staff providing contraception via telemedicine in practices across Illinois, including Planned Parenthood of Illinois (PPIL) health centers. We analyzed interview content to identify themes around the perceived impact of telemedicine implementation on contraception access, contraceptive counseling, patient privacy, and provision of long-acting reversible contraception (LARC). RESULTS: Participants perceived that telemedicine implementation improved care by increasing contraception access, increasing focus on counseling while reducing bias, and allowing easier method switching. Participants thought disparities in telemedicine usage and limitations to the technological interface presented barriers to patient care. Participants' perceptions of how telemedicine implementation impacts patient privacy and LARC provision were mixed. Some participants found telemedicine implementation enhanced privacy, while others felt unable to ensure privacy in a virtual space. Participants found telemedicine modalities useful for counseling patients considering methods of LARC, but they sometimes presented an unnecessary extra step for those sure about receiving one at a practice offering same day insertion. CONCLUSION: Providers felt telemedicine provision of contraception positively impacted patient care. Improvements to counseling and easier access to method switching suggest that telemedicine implementation may help reduce contraceptive coercion. Our findings highlight the need to integrate LARC care with telemedicine workflows, improve patient privacy protections, and promote equitable access to all telemedicine modalities.

It is well documented that influenza A viruses selectively package 8 distinct viral ribonucleoprotein complexes (vRNPs) into each virion; however, the role of host factors in genome assembly is not completely understood. To evaluate the significance of cellular factors in genome assembly, we generated a reporter virus carrying a tetracysteine tag in the NP gene (NP-Tc virus) and assessed the dynamics of vRNP localization with cellular components by fluorescence microscopy. At early time points, vRNP complexes were preferentially exported to the MTOC; subsequently, vRNPs associated on vesicles positive for cellular factor Rab11a and formed distinct vRNP bundles that trafficked to the plasma membrane on microtubule networks. In Rab11a deficient cells, however, vRNP bundles were smaller in the cytoplasm with less co-localization between different vRNP segments. Furthermore, Rab11a deficiency increased the production of non-infectious particles with higher RNA copy number to PFU ratios, indicative of defects in specific genome assembly. These results indicate that Rab11a+ vesicles serve as hubs for the congregation of vRNP complexes and enable specific genome assembly through vRNP:vRNP interactions, revealing the importance of Rab11a as a critical host factor for influenza A virus genome assembly.

This report describes an interprofessional rotation for pharmacy and medical students focused on telehealth outreach to patients at high risk for delays in care due to the COVID-19 pandemic. The curriculum was designed around core competencies of interprofessional education. Student activities included participating in interprofessional huddles, collaborating on patient interviews, and practicing interprofessional communication. Three pharmacy students and two medical students completed the rotation. Evaluation was conducted via survey and exit interview. All students successfully increased their knowledge of their own and others' professional roles and demonstrated interprofessional communication and collaboration through telehealth.

OBJECTIVE: The present study investigated the relationship between difficulty initiating sleep and depressed mood and whether it is mediated by repetitive negative thinking. A moderating role of perfectionism was also examined. METHODS: We surveyed 393 adolescents aged 14 to 20 years (M = 17.32, SD = 1.90) via an online questionnaire that assessed difficulty initiating sleep, repetitive negative thinking, perfectionism, and depressed mood. RESULTS: Results indicated that repetitive negative thinking fully mediated the relationship between difficulty initiating sleep and depressed mood. In addition, this relationship was moderated by perfectionism, specifically, the relationship between repetitive negative thinking and depressed mood was stronger among more perfectionistic adolescents. CONCLUSIONS: These findings highlight that repetitive negative thinking is significantly associated with both difficulty initiating sleep and depressed mood, supporting the conceptualization of repetitive negative thinking as a transdiagnostic process. Further, individual differences in perfectionism may amplify the relationship between repetitive negative thinking and mood. The role of repetitive negative thinking and perfectionism in explaining the link between sleep onset problems and depressed mood has important clinical implications through providing possible treatment targets.

OBJECTIVES: In patients with uninvestigated dyspepsia, a common initial management strategy in primary care is to prescribe a course of empiric antisecretory therapy and to refer those patients who do not respond for endoscopy. The objective of this research was to evaluate the effects of an empiric course of antisecretory therapy on dyspepsia-related health in patients with uninvestigated dyspepsia. METHODS: We conducted a double blind, randomized, placebo-controlled trial in which patients with uninvestigated dyspepsia were randomized to a 6-wk course of omeprazole 20 mg p.o. b.id. versus placebo capsules p.o. bi.d. and followed over 1 yr. The patients were at least 18 yr old with at least a 1-wk history of dyspepsia without alarm features. Dyspepsia-related health was measured using the Severity of Dyspepsia Assessment (SODA), a valid, reliable, disease-specific outcome measure. The primary outcome was treatment failure, defined by a SODA Pain Intensity score > or = 29 (scores, 2-47) during follow-up. Patients who were treatment failures underwent endoscopy. RESULTS: We enrolled 140 patients. The mean age was 51 yr, and seven (5%) were women. At 2 wk there were fewer treatment failures in the omeprazole group: 12 of 71 patients (17%) in the omeprazole group failed compared with 24 of 69 (35%) in the placebo group (p = 0.037, log rank test). Also, at 6 wk there were fewer failures in the omeprazole group: 21 of 71 patients (30%) in the omeprazole group failed compared with 31 of 69 (45%) in the placebo group in 0.067, log rank test). However, at the 1-yr follow-up, there was no significant difference in treatment failure rates in the two groups: 37 of 71 patients (52%) in the omeprazole group failed compared with 41 of 69 (59%) in the placebo group (p = 0.28, log rank test). CONCLUSIONS: In patients with uninvestigated dyspepsia, as compared with a strategy that would entail prompt endoscopy for all patients, an initial 6-wk course of either placebo or omeprazole reduces the need for endoscopy over a 1-yr follow-up. Compared with placebo, an initial 6-wk course of omeprazole delays, but does not reduce, the need for endoscopy. For proton pump inhibitor therapy to reduce the need for endoscopy, it may need to be given continuously.
