CLC Estimator: A Tool for Latent Construct Estimation via Congeneric Approaches in Survey Research.

This article proposes the Shiny app 'CLC Estimator' -Congeneric Latent Construct Estimator- to address the problem of estimating latent unidimensional constructs via congeneric approaches. While congeneric approaches provide more rigorous results than suboptimal parallel-based scoring methods, most statistical packages do not provide easy access to congeneric approaches. To address this issue, the CLC Estimator allows social scientists to use congeneric approaches to estimate latent unidimensional constructs smoothly. The present app provides a novel solution to the challenge of limited access to congeneric estimation methods in survey research.

How Could Medical and Surgical Treatment Affect the Quality of Life in Glaucoma Patients? A Cross-Sectional Study.

BACKGROUND: To evaluate and compare the visual function and the quality of life (QoL) in glaucomatous patients treated with topical medical therapy (TMT) alone, canaloplasty (CP), or trabeculectomy (TB). METHODS: A total of 291 eyes of 167 patients with primary open-angle glaucoma or secondary pseudoexfoliative glaucoma in TMT or surgically treated with CP or TB were included. Eligibility criteria for surgical patients included not needing TMT after surgery. Each patient underwent a visual field assessment and peripapillary retinal nerve fiber layer (pRNFL) optical coherence tomography and filled out the Glaucoma Symptoms Scale (GSS) questionnaire and the 25-Item National Eye Institute Visual Functioning Questionnaire (25-NEI-VFQ). Comparison between the QoL level of the three groups and its correlation with optic nerve's anatomical and functional status was the primary outcome. RESULTS: CP patients reported the best general vision (p = 0.01), a lower incidence of eye burning (p = 0.03), and the lowest annoyance level of non-visual symptoms (p = 0.006). QoL positively correlated with pRNFL thickness, whereas no correlation was found with visual field damage. CONCLUSION: CP provides a better QoL when compared both to TB and TMT, regardless of glaucoma stage. pRNFL seems to provide additional information for predicting change in QoL.

Suicide and suicides attempts in Italian prison epidemiological findings from the "Triveneto" area, 2010-2016.

The aim of this observational study was to assess rates of suicide and suicide attempts, in relation to gender, age, place of birth and security levels, in north-eastern Italian prisons during 2010-2016, and investigate associations with prison overcrowding, offence type and prior self-harm and suicide attempts. The study was based on individual data on suicides and suicide attempts from 16 prisons, with an average yearly number of 3900 inmates during the study period, for all prisons combined. Descriptive and binomial regression analyses were performed. Rates of suicide and suicide attempts in Triveneto prisons were 1and 15 per 1000 inmates, respectively. >90% of suicides and suicide attempters were men aged between 21 and 49 years old, and most had committed violent offenses. Only half the prisoners who died by suicide and 30% of those who made a suicide attempt in custody were Italians. 'Cooperative witnesses' had the highest mean suicide attempt rate (30/1000 inmates). Fourteen per cent of suicides and 19% of attempters had a prior history of suicide attempts and self-injury. In binomial regression analyses, predictors of suicidal behaviour were being a male inmate in standard security conditions, with a mean age of 30 years. The study highlighted that there is a need for suicide prevention policies in Triveneto; these should take into account predictors of suicidal behaviours and individual characteristics of suicidal inmates. More research is warranted in order to both evaluate the effectiveness of prevention plans and better assess risk of suicide in specific groups, such as cooperative witnesses.
