Psittacid alphaherpesvirus 5 infection in Indian ringneck parakeets in southern California.

ABSTRACT: Four Indian ringneck parakeets (Psittacula krameri; syn. ringneck parrots or rose-ringed parakeets) were submitted by 2 private owners for autopsy following a history of dyspnea and death. Gross findings were varied and included thickening of the left caudal thoracic air sac, white spots throughout the liver, mild dilation of the proventriculus, coelomic effusion, splenomegaly, and pulmonary congestion and edema. Microscopically, the submitted parakeets had significant lesions in the lower respiratory tract, including necrotizing bronchitis, parabronchitis, and interstitial pneumonia with numerous syncytia containing eosinophilic intranuclear inclusions. Electron microscopy of the lungs was compatible with a herpesviral infection and Psittacid alphaherpesvirus 5 (PsAHV5) was detected via PCR and sequencing. There has been inconsistent terminology used with Psittacid alphaherpesvirus 3 and PsAHV5; we attempt here to clarify the reported history of these viruses.

Project description:Colorectal cancer (CRC) screening can reduce cancer deaths. However, screening and abnormal test follow-up rates are low among underserved populations. The screening rates of 19-58%, and rates of colonoscopy completion after abnormal stool tests of 18-57% in community health centers (CHC) systems are low. This highlights an opportunity to improve early detection and decrease burden of CRC in our region. Mailed outreach and navigation programs have been shown to increase colonoscopy completion rate. The next step is to understand how to best implement these programs in the community on a larger scale. To achieve this goal, the investigators propose a Hub-and-Spoke intervention combining centralized strategies to maximize CRC screening, follow-up, and referral-to-care. The investigators hypothesize that this intervention will be superior to usual care for increasing CRC screening, abnormal test follow-up, and referral-to-care. The investigators will conduct a randomized trial to determine effectiveness in: 1) improvement in proportion of individuals up-to-date with screening 3 years post implementation; 2) proportion with abnormal FIT who complete diagnostic colonoscopy within 6 months; and 3) proportion with CRC completing first treatment evaluation. The investigators will also evaluate the implementation, scalability, and sustainability of the multi-level implementation strategy. The intervention consists of: Mailed FIT and Reminders. Eligible individuals will receive an introductory letter describing the importance of CRC screening and noting that follow-up mail will include a FIT Kit. It will also be offered to patients who completed prior mailed FIT with normal test results. All materials will be in English and Spanish. Two weeks later, participants will receive a packet via mail containing the FIT kit, a one-page invitation inviting FIT completion and FIT instructions, a postage-paid envelope for return to the patient’s CHC, and COVID-19 message. For non-compliant individuals not returning the kit, a reminder phone call and text message will be delivered 2 weeks later. The investigators will track returned letters, individuals who are later found to be up-to date with screening, and those who decline screening. The CHC will provide care coordination for patients with an abnormal FIT result.
