Predictors of poor health-related quality of life among people living with HIV aged ≥60 years in the PISCIS cohort: Findings from the Vive+ project.

INTRODUCTION: Advancements in and accessibility to effective antiretroviral therapy has improved the life expectancy of people living with HIV, increasing the proportion of people living with HIV reaching older age (≥60 years), making this population's health-related quality of life (HRQoL) more relevant. Our aim was to identify the determinants of poor HRQoL in people living with HIV aged ≥60 years and compare them with those of their younger counterparts. METHODS: We used data from the 'Vive+' study, a cross-sectional survey conducted between October 2019 and March 2020, nested within the PISCIS cohort of people living with HIV in Catalonia and the Balearic Islands, Spain. We used the 12-item short-form survey (SF-12), divided into a physical component summary (PCS) and a mental component summary (MCS), to evaluate HRQoL. We used the least absolute shrinkage and selection operator for variable selection and used multivariable regression models to identify predictors. RESULTS: Of the 1060 people living with HIV (78.6% males) who participated in the study, 209 (19.7%) were aged ≥60 years. When comparing older people living with HIV (≥60 years) and their younger counterparts, older people exhibited a worse PCS (median 51.3 [interquartile range {IQR} 46.0-58.1] vs. 46.43 [IQR 42.5-52.7], p < 0.001) but a similar MCS (median 56.0 [IQR 49.34-64.7] vs. 57.0 [IQR 48.9-66.3], p = 0.476). In the multivariable analysis, cognitive function correlated with a PCS (ß correlation factor [ß] -0.18, p = 0.014), and depressive symptoms and satisfaction with social role correlated with an MCS (ß 0.61 and ß -0.97, respectively, p < 0.001) in people living with HIV aged ≥60 years. CONCLUSION: Depressive symptoms, poor cognitive function, and lower satisfaction with social roles predict poorer HRQoL in older people living with HIV. These factors need to be considered when designing targeted interventions.

Cross-cultural adaptation and validation of the Social Comfort Questionnaire for Brazilian adult survivors of burns.

PURPOSE: Burn patients may encounter social barriers and stigmatization. The objectives of this study were to adapt the Social Comfort Questionnaire (SCQ) into Brazilian Portuguese and to assess the psychometric properties of the adapted version. METHODS: Cross-cultural adaptation of the 8 items of the SCQ followed international guidelines. We interviewed 240 burn patients and verified the SCQ internal consistency, test-retest reliability and construct validity, correlating the scores with depression [Beck Depression Inventory (BDI)], affect/body image and interpersonal relationships [Burns Specific Health Scale-Revised (BSHS-R)] and self-esteem [Rosenberg's Self-Esteem Scale (RSES)]. We also performed a confirmatory factor analysis (CFA). RESULTS: The cross-cultural adaptation resulted in minor semantic modifications to the original SCQ version. After CFA, a reduced 6-item version showed satisfactory fit to the one-factor model (RMSEA = 0.05, CFI = 0.99, TLI = 0.99). Cronbach alpha's was 0.80, and test-retest intraclass correlation coefficient was 0.86. The final version presented a strong negative correlation with depression (BDI), and strong positive correlations with affect/body image (BSHS-R), interpersonal relationships (BSHS-R) and self-esteem (RSES) (all p < 0.001). CONCLUSION: The results showed that the SCQ Brazilian Portuguese adapted version complies with the validity and reliability criteria required for an instrument assessing social comfort in Brazilian burn patients. The Brazilian version yields a single score that is easy to interpret and well understood by patients.

Testing the PROMIS® Depression measures for monitoring depression in a clinical sample outside the US.

The Patient Reported Outcomes Measurement Information System (PROMIS) was devised to facilitate assessment of patient self-reported health status, taking advantage of Item Response Theory. We aimed to assess measurement properties of the PROMIS Depression item bank and an 8-item static short form in a Spanish clinical sample. A three-month follow-up study of patients with active mood/anxiety symptoms (n = 218) was carried out. We assessed model unidimensionality (Confirmatory Item Factor Analysis), reliability (internal consistency and Item Information Curves), and validity (convergent-discriminant with correlations; known-groups with comparison of means and effect sizes; and criterion validity with Receiver operating Characteristics (ROC) analysis). We also assessed 3-month responsiveness to change (Cohen's effect sizes (d) in stable and recovered patients). The unidimensional model showed adequate fit (CFI = 0.97, RMSEA = 0.08). Information Curves had reliabilities over 0.90 throughout most of the score continuum. As expected, we observed high correlations with external self-reported depression, and moderate with self-reported anxiety and clinical measures. The item bank showed an increasing severity gradient from no disorder (mean = 48, SE = 0.6) to depression with comorbid anxiety (mean = 55.8, SE = 0.4). PROMIS detected depression disorder with great accuracy according to the area under the curve (AUC = 0.89). Both formats, item bank and short form, were highly responsive to change in recovered patients (d > 0.7) and had small changes in stable patients (d < 0.2). The good metric properties of the Spanish PROMIS Depression measures provide further evidence of their adequacy for monitoring depression levels of patients in clinical settings. This double check of quality (within countries and populations) supports the ability of PROMIS measures for guaranteeing fair comparisons across languages and countries in specific clinical populations.

[The development of antisocial behavior: psychobiological and environmental factors and gene-environment interactions]. / Desarrollo del comportamiento antisocial: factores psicobiológicos, ambientales e interacciones genotipo-ambiente.

INTRODUCTION: Antisocial behavior is a complex phenomenon with strong implications in neurology and psychiatry. In order to study the ontogenetic development of antisocial behavior, we must check for the existence of physiological mechanisms related to it, and to understand its environmentally-modulated functioning. AIM: To review the state-of-the-art of the development of antisocial behavior, and especially, of the interaction between environmental and genetic factors. DEVELOPMENT: Recent research has highlighted certain brain alterations linked to violent behavior, either at structural, or functional or biochemical levels. Genetic research has also made some advances in this field, discovering some genes--i.e. monoamineoxidase A (MAOA)--related to antisocial behavior. However, the importance of environmental factors in its development must not be left behind. Recent studies have shown that individuals carrying a low transcriptional activity allele of the MAOA gene, and that also suffered severe maltreatment are more prone to antisocial behavior. This interaction is biologically relevant, as there are underlying biological mechanisms that may be able to explain the ethiopathogeny of antisocial behavior. CONCLUSIONS: Although the works herein presented pioneered the field, they are limited by the fact that all the reviewed variables are associated to antisocial behavior, but they lack direct causal evidence of their effects on antisocial behavior. Undoubtedly, future research on psychobiological mechanisms and the understanding of their environmental modulation will help finding therapeutic targets and preventive strategies for antisocial behavior.
