PurposeWe used quantitative magnetic resonance imaging to prospectively analyze the association between microstructural damage to memory-associated structures within the medial temporal lobe and longitudinal memory performance after brain radiation therapy (RT).Methods and materialsPatients with a primary brain tumor receiving fractionated brain RT were enrolled on a prospective trial (n = 27). Patients underwent high-resolution volumetric brain magnetic resonance imaging, diffusion-weighted imaging, and neurocognitive testing before and 3, 6, and 12 months post-RT. Medial temporal lobe regions (hippocampus; entorhinal, parahippocampal, and temporal pole white matter [WM]) were autosegmented, quantifying volume and diffusion biomarkers of WM integrity (mean diffusivity [MD]; fractional anisotropy [FA]). Reliable change indices measured changes in verbal (Hopkins Verbal Learning Test-Revised) and visuospatial (Brief Visuospatial Memory Test-Revised [BVMT-R]) memory. Linear mixed-effects models assessed longitudinal associations between imaging parameters and memory.ResultsVisuospatial memory significantly declined at 6 months post-RT (mean reliable change indices, -1.3; P = .012). Concurrent chemotherapy and seizures trended toward a significant association with greater decline in visuospatial memory (P = .053 and P = .054, respectively). Higher mean dose to the left temporal pole WM was significantly associated with decreased FA (r = -0.667; P = .002). Over all time points, smaller right hippocampal volume (P = .021), lower right entorhinal FA (P = .023), greater right entorhinal MD (P = .047), and greater temporal pole MD (BVMT-R total recall, P = .003; BVMT-R delayed recall, P = .042) were associated with worse visuospatial memory. The interaction between right entorhinal MD (BVMT-R total recall, P = .021; BVMT-R delayed recall, P = .004) and temporal pole FA (BVMT-R delayed recall, P = .024) significantly predicted visuospatial memory performance.ConclusionsBrain tumor patients exhibited visuospatial memory decline post-RT. Microstructural damage to critical memory regions, including the hippocampus and medial temporal lobe WM, were associated with post-RT memory decline. The integrity of medial temporal lobe structures is critical to memory performance post-RT, representing possible avoidance targets for memory preservation.

Background and purposeExecutive function (EF) decline is common after brain radiation therapy (RT), yet the etiology is unclear. We analyzed the association between longitudinal changes in frontal lobe white matter microstructure and decline in EF following RT in brain tumor patients on a prospective clinical trial.Materials and methodsDiffusion tensor imaging was obtained on 22 patients with brain tumors prior to RT, as well as 3- and 6-months post-RT, in a prospective, observational trial. Fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD) were calculated within the superficial white matter (SWM) of the anterior cingulate (AC) and dorsolateral prefrontal cortex. Measures of cognitive flexibility, verbal fluency, and verbal set-shifting were obtained pre- and post-RT. Reliable change indices were calculated to determine significant baseline to 6-month EF changes.ResultsDecreases in FA and increases in MD were observed in the caudal AC (CAC) at 3-months post-RT. CAC changes were characterized by increased RD bilaterally. From baseline to 6-months post-RT, decreased FA and increased MD and RD of the CAC was associated with decline in verbal set-shifting ability, whereas increased MD in the CAC was associated with a decline in cognitive flexibility.ConclusionWhite matter underlying the AC may be particularly vulnerable to radiation effects. Early microstructural loss within AC SWM represents an important biomarker for EF decline, and dose reduction in this region may represent a possibility for cognitive preservation for patients receiving radiotherapy.

PurposeNeurologic deficits that may be manifested as cognitive impairment contribute to the challenges faced by caregivers of patients with brain metastases. To better address their needs, we examined how caregivers respond to these challenges and explore the relationship between the patient's cognitive impairment and caregiver resilience and coping.MethodsWe conducted a descriptive, cross-sectional study using self-reported data from 56 caregivers of patients with brain metastases. Study participants from a comprehensive cancer center were asked to complete a series of instruments that measured their perception of the patient's cognitive dysfunction (revised memory and behavior problems checklist, RMBC), their own personal resilience (Resilience Scale, RS), and their utilization of a broad range of coping responses (COPE inventory and Emotional-Approach Coping scale).ResultsCaregivers reported that memory-related problems occurred more frequently in the patients they cared for compared to depression and disruptive behavior (mean scores 3.52 vs 2.34 vs. 1.32, respectively). Coping strategies most frequently used by caregivers were acceptance (3.28), planning (3.08), and positive reinterpretation and growth (2.95). Most caregivers scored moderate to high on the RS (77%). The coping strategy acceptance correlated significantly with the memory and disruptive behavior subscales of the RMBC.ConclusionsGiven the protective effect of problem-focused coping and the high rate of caregivers utilizing less effective coping strategies in instances of worsening cognitive dysfunction, healthcare professionals need to systematically assess the coping strategies of caregivers and deliver a more personalized approach to enhance effective coping among caregivers of patients with brain metastases.

Goal Attainment Scaling (GAS), an individualized measurement approach, is particularly attractive for the evaluation and care planning of frail elders, who often experience multiple, complex problems. Some service providers find GAS too unwieldy for routine use. A modified version of GAS that uses a standardized menu of goals and attainment levels has been developed by the Geriatric Assessment and Rehabilitation Unit of a regional referral hospital in Nova Scotia, Canada. This article reviews the development, implementation, benefits, and challenges of the standardized menu, as well as the results of a retrospective descriptive study of its measurement properties. The standardized menu appears to be a feasible, valid, and responsive alternative to traditional GAS, while retaining much of its individualized nature.

The purpose of this study was to evaluate the effect of a nutrition education module, emphasizing both cognitive and affective concepts, on the nutrition knowledge, flexibility of attitude toward nutrition and attitude aabout nutrition education of missionaries during their orientation period. The experimental (n = 22) and control (n = 19) groups completed pre- and post-test questionnaires that were developed for this study. Missionaries in the experimental group demonstrated significant increases in both nutrition knowledge and more positive attitudes about nutrition education after participation in the module. The control group, however, had no significant increase in knowledge at post-testing and, in general, had significantly more negative attitudes about nutrition education. No significant changes in flexibility were detected for the control group and only for one statement in the experimental group. Significant positive correlations resulted at post-testing between nutrition knowledge and attitude, as well as knowledge and flexibility for the experimental group and between flexibility and attitude for both the experimental and control groups. Results from this study suggest that a change in nutrition knowledge precedes a change in attitude in the knowledge-attitude-behavior pathway as revealed by an analysis of covariance. This sequence supports the principles of adult learning and the theory of holistic education upon which the program of missionary orientation is based.

Abstract Background In 6-month anti-dementia drug trials, a 4-point change in the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) is held to be clinically important. We examined how this change compared with measures of clinical meaningfulness. Methods This is a secondary analysis of a 12 month open-label study of 100 patients (71 women) diagnosed with mild to moderate AD treated with 5–10 mg of donepezil daily. We studied the observed case, 6-month change from baseline on the ADAS-Cog, the Clinician's Interview Based Impression of Change-Plus Caregiver Input (CIBIC-Plus), patient-Goal Attainment Scaling (PGAS) and clinician-GAS (CGAS). Results At 6 months, donepezil-treated patients (n = 95) were more likely to show no change (+/- 3 points) on the ADAS-Cog (56%) than to improve (20%) or decline (24%) by 4-points. ADAS-Cog change scores were little correlated with other measures: from -0.09 for PGAS to 0.27 for the CIBIC-Plus. While patients who improved on the ADAS-Cog were less likely to decline on the clinical measures (26%), 43% of patients who declined on the ADAS-Cog improved on at least two of the clinical measures. Conclusion The ADAS-Cog did not capture all clinically important effects. In general, ADAS-Cog improvement indicates clinical improvement, whereas many people with ADAS-Cog decline do not show clinical decline. The open-label design of this study does not allow us to know whether this is a treatment effect, which requires further investigation.

A study on households, in which one or more participants were a part of Special Supplement Food Program for Women, Infants and Children (WIC) and examining the prevalence of food insecurity, is presented. The results indicate that 35% experience food insecurity, and this was high among female-headed households and in households with 5 years and younger children.

Introduction: Cholinesterase inhibitors (ChEIs) and memantine are medications used to treat the symptoms of specific types of dementia. Their benefits and harms can change over time, particularly during long term use. Therefore, appropriate use of ChEIs and memantine involves both prescribing these medications to individuals who are likely to benefit, and deprescribing (withdrawing) them from individuals when the risks outweigh the benefits. We recently developed an evidence-based clinical practice guideline for deprescribing ChEIs and memantine, using robust international guideline development processes.Main Recommendations: Our recommendations aim to assist clinicians to: identify individuals who may be suitable for a trial of deprescribing ChEIs and memantine (such as those who do not have an appropriate indication, those who have never experienced a benefit, those who appear to be no longer benefitting, and those who have severe or end-stage dementia); and taper treatment and monitor individuals during the deprescribing process.Changes in Management AsA Result Of the Guideline: Deprescribing ChEIs and memantine through shared decision making with individuals and their caregivers by: ▶determining their treatment goals; ▶discussing benefits and harms of continuing and ceasing medication, from the start of therapy and throughout; and ▶engaging them in monitoring after discontinuation, while informing carers that the individual will continue to decline after discontinuation. This approach may reduce adverse drug reactions and medication burden, leading to improved quality of life in people with dementia. [ABSTRACT FROM AUTHOR]
