Narrative review of the psychometric properties of language tests used in anomia treatment for primary progressive aphasia (PPA)

Background: Primary progressive aphasia (PPA) is a neurodegenerative dementia in which language decline is the first and most prominent symptom. Among several interventions for PPA, language rehabilitation has been the most frequently used.

Aims: This narrative review aimed to evaluate existing standardised language tests used in the assessment of PPA, in order to determine whether they are appropriate and psychometrically adequate to detect change over time in the treatment of anomia.

Main Contribution: The present findings highlight the scarcity of psychometrically robust instruments used to measure therapy-induced gains in PPA. Additionally, most of these instruments were not validated for use with the PPA population, which consequently might bias the results. There is a need for population-based norms for existing instruments.

Conclusions: The accurate assessment of lexico-semantic deficits in PPA should rely on objective, reliable, valid, and responsive outcome measures. Psychometric studies are needed to evaluate and eventually improve the quality of language tests used in clinical practice.     

Is there an association between overweight/obesity and dental implant complications? A systematic review and meta-analysis

The aim of this systematic review was to test the following hypotheses: (1) that there is no difference in implant survival rate between individuals with overweight or obesity and those who are within the ideal weight range; (2) that there are no differences between these groups regarding indicators of peri-implant health. Two independent reviewers performed a literature search of the PubMed/MEDLINE, Scopus, and Cochrane Library databases for studies published up to April 1, 2018. A meta-analysis was performed to determine the risk difference for implant failure and mean difference for marginal bone loss, probing depth, and bleeding on probing. Six studies were selected for review, involving a total of 746 patients with 986 implants: 609 in overweight or obese individuals and 377 in individuals within the ideal weight range. The findings of this systematic review indicate that the first hypothesis should be accepted, since no statistically significant difference in implant survival rate was found between individuals with overweight/obesity and those within the ideal weight range (P = 0.64). The second hypothesis was rejected, as the review indicated a difference in marginal bone loss (P < 0.00001), probing depth (P < 0.00001), and bleeding around dental implants (P < 0.00001).     

Bad news: Families’ experiences and feelings surrounding the diagnosis of Zika‐related microcephaly

The rapidly increasing number of cases of Zika virus and limited understanding of its congenital sequelae (e.g., microcephaly) led to stories of fear and uncertainty across social media and other mass communication networks. In this study, we used techniques generic to netnography, a form of ethnography, using Internet‐based computer‐mediated communications as a source of data to understand the experience and perceptions of families with infants diagnosed with Zika‐related microcephaly. We screened 27 YouTube? videos published online between October 2015 and July 2016, during which the Zika epidemic started, peaked, and declined. We identified three themes: (a) experiencing the news of a diagnosis of Zika‐associated microcephaly; (b) experiencing feelings and expectations of the ‘imperfect’ child; and (c) seeking to understand microcephaly to care for the child. We found that families experienced distressing feelings of shock, sadness, hopelessness, and pain, while dealing with emerging and sometimes conflicting information being transmitted by news outlets, uncertainty about the child's health, and healthcare providers’ lack of clarity to guide the family members. The ‘unknown’ factor of ZIKA was an additional stressful factor in the experience of the families.

The Impact of Socioeconomic Factors,Coverage and Access to Health on Heart Ischemic Disease Mortality in a Brazilian Southern State: A Geospatial Analysis

Background:No other disease has killed more than ischemic heart disease (IHD) for the past few years globally. Despite the advances in cardiology, the response time for starting treatment still leads patients to death because of the lack of healthcare coverage and access to referral centers.Objectives:To analyze the spatial disparities related to IHD mortality in the Parana state, Brazil.Methods:An ecological study using secondary data from Brazilian Health Informatics Department between 2013–2017 was performed to verify the IHD mortality. An spatial analysis was performed using the Global Moran and Local Indicators of Spatial Association (LISA) to verify the spatial dependency of IHD mortality. Lastly, multivariate spatial regression models were also developed using Ordinary Least Squares and Geographically Weighted Regression (GWR) to identify socioeconomic indicators (aging, income, and illiteracy rates), exam coverage (catheterization, angioplasty, and revascularization rates), and access to health (access index to cardiologists and chemical reperfusion centers) significantly correlated with IHD mortality. The chosen model was based on p < 0.05, highest adjusted R² and lowest Akaike Information Criterion.Results:A total of 22,920 individuals died from IHD between 2013–2017. The spatial analysis confirmed a positive spatial autocorrelation global between IDH mortality rates (Moran’s I: 0.633, p < 0.01). The LISA analysis identified six high-high pattern clusters composed by 66 municipalities (16.5%). GWR presented the best model (Adjusted R²: 0.72) showing that accessibility to cardiologists and chemical reperfusion centers, and revascularization and angioplasty rates differentially affect the IHD mortality rates geographically. Aging and illiteracy rate presented positive correlation with IHD mortality rate, while income ratio presented negative correlation (p < 0.05).Conclusion:Regions of vulnerability were unveiled by the spatial analysis where sociodemographic, exam coverage and accessibility to health variables impacted differently the IHD mortality rates in Paraná state, Brazil.Highlights

• The increase in ischemic heart disease mortality rates is related to geographical disparities.
• The IHD mortality is differentially associated to socioeconomic factors, exam coverage, and access to health.
• Higher accessibility to chemical reperfusion centers did not necessarily improve patient outcomes in some regions of the state.
• Clusters of high mortality rate are placed in regions with low amount of cardiologists, income and schooling.
