Visual complaints of patients with glaucoma and controls under optimal and extreme luminance conditions.
Acta Ophthalmol. 2018 Mar 09;:
Authors: Bierings RAJM, van Sonderen FLP, Jansonius NM
Abstract
PURPOSE: To determine (i) whether, compared to controls, visual complaints of glaucoma patients are more pronounced under extreme luminance conditions than in the optimal luminance condition and (ii) whether complaints belonging to different extreme luminance conditions are associated.
METHODS: We developed a luminance-specific questionnaire and sent it to 221 glaucoma patients (response rate 81%); controls (182) were primarily their spouses. Median (interquartile range) mean deviation of the visual field of the patients’ better eye was -4.5 (-10.7 to -1.9) dB. Questions were addressing visual performance under five luminance conditions: presumed optimal (outdoor on a cloudy day), low, high, sudden decrease and sudden increase. We compared percentages of patients and controls who reported visual complaints while performing activities under different luminance conditions.
RESULTS: Percentages of patients and controls with visual complaints were 4 versus 0% (p = 0.02) for optimal luminance and 48 versus 6% (p < 0.001), 22 versus 1% (p < 0.001), 32 versus 1% (p < 0.001) and 25 versus 3% (p < 0.001) for low, high, sudden decrease and sudden increase in luminance. Within the group of glaucoma patients, the frequency of complaints increased significantly with increasing disease severity at a Bonferroni-corrected p value of 0.003 for all but one (p = 0.005) luminance-specific questions that addressed extreme luminance conditions.
CONCLUSION: The concept of (early stage) glaucoma as an asymptomatic disease is only valid with optimal luminance. Differences in visual complaints between glaucoma patients and controls are greater under extreme luminance conditions, especially in the dark. The fact that the cases were aware of their diagnosis could have induced bias.

A Reconsideration of the Self-Compassion Scale’s Total Score: Self-Compassion versus Self-Criticism.
PLoS One. 2015;10(7):e0132940

Abstract
The Self-Compassion Scale (SCS) is currently the only self-report instrument to measure self-compassion. The SCS is widely used despite the limited evidence for the scale’s psychometric properties, with validation studies commonly performed in college students. The current study examined the factor structure, reliability, and construct validity of the SCS in a large representative sample from the community. The study was conducted in 1,736 persons, of whom 1,643 were included in the analyses. Besides the SCS, data was collected on positive and negative indicators of psychological functioning, as well as on rumination and neuroticism. Analyses included confirmatory factor analyses (CFA), exploratory factor analyses (EFA), and correlations. CFA showed that the SCS’s proposed six-factor structure could not be replicated. EFA suggested a two-factor solution, formed by the positively and negatively formulated items respectively. Internal consistency was good for the two identified factors. The negative factor (i.e., sum score of the negatively formulated items) correlated moderately to strongly to negative affect, depressive symptoms, perceived stress, as well as to rumination and neuroticism. Compared to this negative factor, the positive factor (i.e., sum score of the positively formulated items) correlated weaker to these indicators, and relatively more strongly to positive affect. Results from this study do not justify the common use of the SCS total score as an overall indicator of self-compassion, and provide support for the idea, as also assumed by others, that it is important to make a distinction between self-compassion and self-criticism.

Weight and height in children newly diagnosed with cancer.
Pediatr Blood Cancer. 2014 Oct 30;

Abstract
BACKGROUND: Although weight loss and lack of linear growth occur in children with cancer, growth history is not included in research that aims to determine nutritional status in children newly diagnosed with cancer. Therefore, this study aimed to determine weight loss and lack of linear growth in this patient group.
PROCEDURE: Weight and height were recorded in 95 children (ages 1.5-10 years) at diagnosis and compared with data predicted from growth curves. Age, gender, type of malignancy, extent of disease, and prior weight and height were tested for their potential relation to differences between actual and predicted data.
RESULTS: The incidence of undernutrition, based on z-scores for weight-for-age (WFA), height-for-age (HFA), and weight-for-height (WFH), was 2%, 4%, and 7%, respectively. Actual z-scores were lower than predicted z-scores. Differences between actual and predicted z-scores of <-0.5 standard deviation score (SDS) in WFA, HFA, or WFH were found in 25%, 23%, and 29% of the children, respectively. Children with advanced cancer had the highest risk of significant weight loss (<-0.5 SDS in WFA) (ORWFA = 3.45, P = 0.012) prior to diagnosis. Differences were unrelated to type of malignancy, age, gender, and weight and height prior to diagnosis.
CONCLUSIONS: At diagnosis, approximately 25% of the children showed a significant reduction in z-scores for weight-for-age, height-for-age, and weight-for-height. This reduction may indicate a deteriorated nutritional status. Therefore, assessment of growth history should be standard of care to ensure appropriate nutritional interventions and should be included in research that aims to evaluate nutritional status in children newly diagnosed with cancer.
