The generalizability of Older Adult Self-Report (OASR) syndromes of psychopathology across 20 societies

OBJECTIVES

As the world population ages, psychiatrists will increasingly need instruments for measuring constructs of psychopathology that are generalizable to diverse elders. The study tested whether syndromes of co-occurring problems derived from self-ratings of psychopathology by US elders would fit self-ratings by elders in 19 other societies.

METHODS/DESIGN

The Older Adult Self-Report (OASR) was completed by 12 826 adults who were 60 to 102 years old in 19 societies from North and South America, Asia, and Eastern, Northern, Southern, and Western Europe, plus the United States. Individual and multigroup confirmatory factor analyses (CFAs) tested the fit of the seven-syndrome OASR model, consisting of the Anxious/Depressed, Worries, Somatic Complaints, Functional Impairment, Memory/Cognition Problems, Thought Problems, and Irritable/Disinhibited syndromes.

RESULTS

In individual CFAs, the primary model fit index showed good fit for all societies, while the secondary model fit indices showed acceptable to good fit. The items loaded strongly on their respective factors, with a median item loading of .63 across 20 societies, and 98.7% of the loadings were statistically significant. In multigroup CFAs, 98% of items demonstrated approximate or full metric invariance. Fifteen percent of items demonstrated approximate or full scalar invariance, and another 59% demonstrated scalar invariance across more than half of societies.

CONCLUSIONS

The findings supported the generalizability of OASR syndromes across societies. The seven syndromes offer empirically based clinical constructs that are relevant for elders of different backgrounds. They can be used to assess diverse elders and as a taxonomic framework to facilitate communication, services, research, and training in geriatric psychiatry.

Prevalence and determinants of early childhood caries in Italy

AIM

Still limited data from representative surveys are available on the prevalence of Early Childhood Caries (ECC; i.e., the presence of one or more decayed, missing, or filled tooth surfaces in any primary tooth in a child aged 71 months or younger), particularly for infant. We conducted a survey in Italian children aged 0 to 71 months.

MATERIALS AND METHODS

A cross-sectional study on ECC was conducted in Italy in 2018 on a sample of parents who were members of an online panel. Using an online questionnaire, 2,522 parents provided information on a total sample of 3,000 children, representative of the Italian population aged 0-71 months.

RESULTS

ECC prevalence was 8.2% overall, 2.9% in children aged 0-23 months, 6.2% in children aged 24-47 and 14.7% in children aged 48-71 months (p for trend<0.001). ECC was more frequently observed among children using baby bottle with milk to fall asleep (multivariate odds ratio, OR, 1.36, 95% confidence interval, CI: 1.03-1.78), baby bottle with sugary beverages (OR 2.87, 95% CI: 2.05-4.03) and pacifier with sugary substances (OR 2.49, 95% CI: 1.79-3.47), consuming beverages other than water (OR for ?1/day vs never 2.29, 95% CI: 1.35-3.90), a higher number of snacks between meals (OR for ?3 vs <2 meals 2.05, 95% CI: 1-38-3.06), a lower frequency of tooth brushing (OR for <1 vs ?2 times/day 2.26, 95% CI: 1.42-3.58) and a high number of siblings (compared to 0, OR for ?2 siblings 2.28, 95% CI: 1.56-3.34). ECC increased with parents' mean age (p for trend=0.048), parents' smoking habit (OR for at least one smoker 1.54, 95% CI: 1.17-2.03), parents' poor oral hygiene (OR for ?1 vs >1 time/day of tooth brushing 1.42, 95% CI: 1.03-1.96) and high number of caries (OR for ?7 vs 0 caries was 2.38, 95% CI: 1.35-4.20).

CONCLUSION

The present large and representative survey for the first time shows that ECC might be frequent also among infants. We confirm that ECC might be prevented if parents follow simple good practices. Information campaign and intervention programmes are needed to inform parents about unfavourable habits that favour the onset of ECC.

Lower Tinetti scores can support an early diagnosis of spatial neglect in post-stroke patients

BACKGROUND

Neglect represents a severe complication of stroke, which impairs patients' daily activities. An early diagnosis of neglect is fundamental for management decisions.

AIM

The aim of this study is to evaluate the usefulness of the Tinetti Test as an outcome of spatial neglect in post-stroke patients.

DESIGN

Observational retrospective data analysis.

SETTING

Rehabilitation Hospital.

POPULATION

Cohort of post-stroke adults admitted in our Rehabilitation Unit.

METHODS

One hundred and sixty stroke patients were evaluated between the 1st of January 2015 and the 31st of December 2016 at our Department. Eighty-nine inpatients matched the inclusion criteria. Their scores of the Tinetti Test for balance condition and gait function were compared with Bells Test and line bisection task for spatial neglect. Global independence activity was also assessed using Barthel Index and global cognitive functioning by means of the Mini-Mental State Examination.

RESULTS

Twenty-two patients between the 89 patients included in this study were affected by spatial neglect at admission. A high statistical significant correlation was observed between lower Tinetti scores and neglect presence (mean Tinetti Score: 2.36 neglect; 7.82 non-neglect; P<0.001).

CONCLUSIONS

The Tinetti Test is a well-established assessment scale to measure balance ability and gait function in post-stroke patients. Results from this study suggest that Tinetti Test may be considered as an early ecological screening tool for the diagnosis of neglect in post-stroke patients.

CLINICAL REHABILITATION IMPACT

The alternative use of the Tinetti Test for the diagnosis of spatial neglect.

The Biological Tumor Markers' Myopia: A Model with CA 125 and Second-look in Ovarian Cancer

Preoperative CA 125 levels were measured in 36 patients with advanced epithelial ovarian carcinoma in clinical response undergoing a second-look operation. All the patients had positive levels (> 35 U/ml) of this tumor marker at diagnosis. The correlation between antigen levels and disease status at surgery revealed a sensitivity of this assay of 0.55 (only 11/20 patients still with tumor had positive levels) and a specificity of 0.94 (15/16 patients with no tumor had < 35 U/ml). The predictive value of a positive test was 0.92. This method unfortunately proved unable to recognize microscopic residual tumor burden, less than 0.5 cm.

Functional and Structural Brain Damage in Friedreich's Ataxia

Friedreich's ataxia (FRDA) is a rare hereditary neurodegenerative disorder caused by a GAA repeat expansion in the FXN gene. There is still no cure or quantitative biomarkers reliaby correlating with the progression rate and disease severity. Investigation of functional and structural alterations characterizing white (WM) and gray matter (GM) in FRDA are needed prerequisite to monitor progression and response to treatment. Here we report the results of a multimodal cross-sectional MRI study of FRDA including Voxel-Based Morphometry (VBM), diffusion-tensor imaging (DTI), functional MRI (fMRI), and a correlation analysis with clinical severity scores. Twenty-one early-onset FRDA patients and 18 age-matched healthy controls (HCs) were imaged at 3T. All patients underwent a complete cognitive and clinical assessment with ataxia scales. VBM analysis showed GM volume reduction in FRDA compared to HCs bilaterally in lobules V, VI, VIII (L>R), as well as in the crus of cerebellum, posterior lobe of the vermis, in the flocculi and in the left tonsil. Voxel-wise DTI analysis showed a diffuse fractional anisotropy reduction and mean, radial, axial (AD) diffusivity increase in both infratentorial and supratentorial WM. ROI-based analysis confirmed the results showing differences of the same DTI metrics in cortico-spinal-tracts, forceps major, corpus callosum, posterior thalamic radiations, cerebellar penduncles. Additionally, we observed increased AD in superior (SCP) and middle cerebellar peduncles. The WM findings correlated with age at onset (AAO), short-allelle GAA, and disease severity. The intragroup analysis of fMRI data from right-handed 14 FRDA and 15 HCs showed similar findings in both groups, including activation in M1, insula and superior cerebellar hemisphere (lobules V-VIII). Significant differences emerged only during the non-dominant hand movement, with HCs showing a stronger activation in the left superior cerebellar hemisphere compared to FRDA. Significant correlations were found between AAO and the fMRI activation in cerebellar anterior and posterior lobes, insula and temporal lobe. Our multimodal neuroimaging protocol suggests that MRI is a useful tool to document the extension of the neurological impairment in FRDA.
