Patterns of ongoing thought in the real world.

Health and well-being are impacted by our thoughts and the things we do. In the laboratory, studies suggest specific task contexts impact thought processes. More broadly, this suggests the people we are with, the places we are in, and the activities we perform may influence our thought patterns. In our study, participants completed experience sampling surveys for five days in daily life. Principal component analysis decomposed this data to identify common "patterns of thought," and linear mixed modelling related these patterns to the participants' activities. Our study replicated the influence of socializing on patterns of thought and established that this is part of a broader set of relationships linking activities to how thoughts are organized in daily life. Our study suggests sampling thinking in the real world may help map thoughts to activities, and these "thought-activity" mappings could be useful to researchers and health care professionals interested in health and well-being.

Conjunctival lymphoid hyperplasia presenting with bilateral panuveitis.

PURPOSE: To report on a case of bilateral conjunctival lymphoid hyperplasia presenting with bilateral panuveitis in a female patient. DESIGN: Observational case report. METHODS: In this case excisional biopsy indicated lymphoid tissue. Immunohistochemistry showed a follicular architecture with appropriate zoning of B and T lymphocytes. RESULTS: Causes of panuveitis were considered and excluded based on a detailed history, physical examination, and laboratory investigations. The bilateral panuveitis resolved on topical corticosteroids and visual acuity returned to normal. CONCLUSIONS: Ocular adnexal lymphoproliferative lesions consist of a spectrum of disease entities, including reactive lymphoid hyperplasia, atypical lymphoid hyperplasia, and lymphoma. There are no established clinical criteria to differentiate between these lesions. This case highlights the importance of a thorough ophthalmic examination in these patients, as an intra-ocular inflammatory process may accompany the conjunctival findings. Furthermore, we advocate periodic follow-up examinations because of the small potential risk of developing ocular or systemic lymphoma in these patients.

The Chirila Keratoprosthesis: phase I human clinical trial.

OBJECTIVE: To undertake a preliminary safety and performance evaluation of an artificial cornea, the Chirila Keratoprosthesis, in human patients. DESIGN: A prospective, interventional case series. PARTICIPANTS: Fourteen consecutive patients with blindness of corneal origin not treatable by repeated standard penetrating keratoplasty. METHODS: Keratoprostheses were manufactured and implanted. The patients, all with preoperative visual acuity of light perception to count fingers (CF), were followed clinically in adherence to a protocol. MAIN OUTCOME MEASURES: Safety (keratoprosthesis retention, incidence of serious complications) and performance (visual acuity, comfort, appearance). RESULTS: Ninety-three percent of keratoprostheses were retained to the date of reporting, up to 2.5 years. One keratoprosthesis (7%) was removed in a manner that restored the patient's preoperative condition. All but one patient maintained their preoperative level of visual acuity or improved on it, with most achieving their estimated full potential visual acuity, (range, count fingers - 20/20). CONCLUSIONS: This keratoprosthesis is acceptably safe and has demonstrated an ability to restore vision in cases in which alternative management would have had a poor prognosis. More extensive trials are warranted.
