Abstract

PURPOSE: To evaluate the accuracy of a parent-administered visual acuity test, using the electronic visual acuity tester (EVA) (JAEB Center, Tampa, FL) and evaluate its use as a means to improve efficiency of office acuity testing. METHODS: This was a prospective experimental study. Part I: Sixty-four children had their visual acuity determined using the EVA, first by their parents and then by an ophthalmic technician. Acuity scores were compared. Part II: Forty-four other children were randomly assigned to one of 2 groups. Group A (parent-prescreen) children had their visual acuity determined first by the parents using the EVA. The visual acuity result in that child was then rechecked by the technician using the Reinforcement Phase and Phase 2 of the Amblyopia Treatment Study (ATS) visual acuity testing protocol. Group B (full ATS protocol) children had their acuity determined by the technician using the full ATS protocol. The number of optotypes presented by the technician in order to determine the acuity in each group was compared. RESULTS: Part I: Reliability of parent-determined visual acuity scores was high (r = 0.91 and 0.81 for right eyes (OD) and left eyes (OS), respectively), with 93% of right eye parent scores and 85% of left eye parent scores within 0.11 logarithm of minimal angle of resolution (logMAR) units (ie, within one line of vision) of the technician score. Part II: The parent prescreen group (Group A) required presentation of 66% fewer optotypes to the OD and 68% fewer optotypes to the OS than the full ATS protocol group (Group B) (OD: P = 5.4 x 10(-18); OS: P = 6.5 x 10(-18)). CONCLUSIONS: Visual acuity testing results by parents using the EVA are reliable. Electronic visual acuity prescreening by parents reduces the number of optotype presentations required to be shown by the technician to accurately determine acuity. Use of a parent-assisted screening system in the waiting room may translate to increased office efficiency.

Caregiver experiences after the death of a person with dementia with Lewy bodies: A mixed-methods analysis.

BackgroundDementia with Lewy bodies (DLB) is a common degenerative dementia, but no studies investigate bereaved caregiver experiences.ObjectiveTo investigate the experiences of caregivers three months after the death of persons with DLB using a mixed-methods approach.MethodsDyads of individuals with moderate-advanced DLB and their primary informal caregivers were followed prospectively every 6 months until the person with DLB died. Caregivers completed a study visit with questionnaires and a semi-structured interview ∼3 months later. Spearman correlation coefficients and Wilcoxon rank-sum tests evaluated the relationships of post-death measures with pre-death patient and caregiver variables. Thematic analysis was used to analyze the interviews.ResultsSeventy-three caregivers completed visits (mean 3.5 months post-death). Most of the caregivers were women (82.2%) and spouses (76.7%) or adult children (17.8%). Over 40% had scores indicating risk for clinical depression. Post-death caregiver experiences (depression, quality of life, grief, resilience) correlated with pre-death caregiver experiences. Post-death experiences did not associate with patient characteristics, disease-related symptoms, or healthcare services used in the last 6 months of life. Trajectories for caregiver measures from pre- to post-death visits varied widely. Interview themes included grief and sadness, anger, guilt and regret, relief, appreciation/gratitude, and adjusting to a new normal.ConclusionsThe finding that pre-death caregiving experiences have the strongest association with post-death experiences emphasizes the critical importance of accessible and evidence-based caregiver support before and after the death of a person with DLB. Research is needed to develop interventions for current and bereaved caregivers of individuals with DLB.Trial registration informationNCT04829656 (submitted 2021-03-22).

[Rehabilitation of parkinsonian patients].

Although most parkinsonian patients greatly benefit from medical and/or surgical treatment, their clinical management should not be limited to these two interventions. Axial symptoms, freezing, postural instability, speech and swallowing problems may be drug-resistant, and disability may persist in spite of improvement of motor symptoms. A coordinate interdisciplinary approach facilitates the clinical management of the disease. Physiotherapy, occupational therapy and speech therapy may contribute to reduce impairment and improve quality of life; a psychological and social support of patients and caregivers helps them carrying the burden of the disease; counseling through a specialized nurse may give practical solutions to problems like bladder incontinence, symptomatic hypotension or hypersalivation. As sensory cueing may help patients bypassing the disease-specific motor control deficits, it should be included in training programs. Rehabilitatory interventions are part of the standards of care of Parkinson's disease and their efficacy is supported by several neurophysiological and clinical investigations. However, the poor methodological quality of most clinical studies as compared with the standard of pharmacological investigations fails to provide clear-cut evidence in favour of rehabilitation.
