Postacute Sequelae of SARS-CoV-2 Infection and Impact on Quality of Life 1-6 Months After Illness and Association With Initial Symptom Severity.

Background: Individuals with coronavirus disease 2019 (COVID-19) may have persistent symptoms following their acute illness. The prevalence and predictors of these symptoms, termed postacute sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; PASC), have not been fully described.

Methods: Participants discharged from an outpatient telemedicine program for COVID-19 were emailed a survey (1-6 months after discharge) about ongoing symptoms, acute illness severity, and quality of life.

Prolonged Symptoms After COVID-19 Infection in Outpatients.

We review 127 encounters for polymerase chain reaction-confirmed coronavirus disease 2019 (COVID-19) infection at a multidisciplinary outpatient clinic. We describe the symptomatology, time course, exam, and radiographic findings in this population. Patients with COVID-19 can experience persistent symptoms, primarily respiratory in nature, which can be severe enough to warrant hospitalization.

Optimizing Discharge Summaries: A Multispecialty, Multicenter Survey of Primary Care Clinicians.

Background: Patient care in the United States has become increasingly more fragmented, and the discharge summary serves as a critical tool for transmitting information on a patient's hospital admission to the primary care clinician. Some guidelines regarding how to write discharge summaries exist, but few are focused on prioritizing content that is most important to optimize a patient's transition of care.

Methods: We conducted a national survey across various medical primary care specialties, including trainees and advanced practice providers, to understand the priorities of primary care clinicians.

Gene expression profiles of mouse retinas during the second and third postnatal weeks.

Mouse retina undergoes crucial changes during early postnatal development. By using Affymetrix microarrays, we analyzed gene expression profiles of wild-type 129SvEv/C57BL/6 mouse retinas at postnatal days (P) 7, 10, 14, 18, and 21 and found significantly altered expression of 355 genes. Characterization of these 355 genes provided insight into physiologic and pathologic processes of mouse retinal development during the second and third postnatal weeks, a period that corresponds to human embryogenesis between weeks 12 and 28.

Distinct gene expression profiles and reduced JNK signaling in retinitis pigmentosa caused by RP1 mutations.

To understand the mechanisms underlying autosomal dominant progressive retinitis pigmentosa (RP) caused by the mutations of the RP1 gene and to identify molecules that play roles in the early disease process, we used Affymetrix U74Av2 microarrays to compare the gene expression profiles of retinas from Rp1-/- and Rp1+/+ mice at postnatal days (P) 7, 10, 14, 18 and 21. These profiles were independently verified by comparison with results of retinal serial analysis of gene expression, U74Av2 array studies of mouse retinas, real-time PCR and in situ hybridization. We found that the disruption of Rp1 significantly affected the expression of multiple clusters of genes whose products were involved in diverse biological pathways.

Purkinje cell degeneration (pcd) phenotypes caused by mutations in the axotomy-induced gene, Nna1.

The classical recessive mouse mutant, Purkinje cell degeneration (pcd), exhibits adult-onset degeneration of cerebellar Purkinje neurons, retinal photoreceptors, olfactory bulb mitral neurons, and selected thalamic neurons, and has defective spermatogenesis. Here we identify Nna1 as the gene mutated in the original pcd and two additional pcd alleles (pcd2J and pcd3J). Nna1 encodes a putative nuclear protein containing a zinc carboxypeptidase domain initially identified by its induction in spinal motor neurons during axonal regeneration.
