Healthcare professionals' perceptions of neglect of older people in Mexico: A qualitative secondary analysis.

AIMS AND OBJECTIVES: To describe healthcare professionals' perceptions of neglect of older people in Mexico. BACKGROUND: Mistreatment of older people, particularly neglect, has emerged as a significant public health concern worldwide. However, few studies have been conducted to examine neglect of older people in low- and middle-income countries. Most research has focused on estimating the prevalence of neglect in older populations with little emphasis on the perceptions of healthcare professionals and their role in addressing neglect of older people. DESIGN: Qualitative secondary analysis. METHODS: The parent study consisted of nine focus groups conducted with healthcare professionals at five public hospitals in Mexico. The purpose of the parent study was to perform a needs assessment to determine the feasibility of adapting the Nurses Improving Care for Healthsystem Elders programme to Mexico. A qualitative secondary analysis with directed content analysis approach was used to extract data related to neglect of older people. RESULTS: A total of 89 participants representing healthcare professionals from several disciplines were interviewed. Three themes emerged: (i) The main point is not here; (ii) We feel hopeless; and (iii) We need preparation. Participants reported distress and hopelessness related to neglect of older people. Lack of community-based resources was noted as contributing to neglect. Increased education regarding care of older people for both caregivers and healthcare professionals and greater interdisciplinary collaboration were identified as potential solutions to combat neglect. CONCLUSIONS: Community-based services and resource allocation need to be re-evaluated to improve the care of older Mexicans. Interdisciplinary models of care should be developed to address concerns related to neglect of older people. IMPLICATIONS FOR PRACTICE: Neglect negatively impacts healthcare professionals' ability to adequately care for older patients. There is a need to invest in community-based services and models of care to address these concerns.

Tooth erosion with low severity does not impact child oral health-related quality of life.

BACKGROUND: Prevalence data about tooth erosion has attracted increasing attention in the dental community; however, no study has addressed the impact of this condition on child oral health-related quality of life (COHRQoL). This study assessed the impact of tooth erosion on COHRQoL. METHODS: This study followed a cross-sectional design, with a multistage random sample of 944 11- to 14-year-old children representative of Santa Maria, a southern city in Brazil. They were examined for recording the prevalence and severity of tooth erosion by 2 examiners. Children completed the Brazilian version of Child Perceptions Questionnaire (CPQ(11-14)) and data about socioeconomic variables of the target population were collected by means of a structured questionnaire. The Poisson regression model using robust variance was performed to assess the association between the predictor variables and the outcomes. RESULTS: Prevalence of tooth erosion (7.2%) and severity were low. Poisson regression models showed a distinct gradient in mean CPQ(11-14) scores by socioeconomic indicators. Children with tooth erosion with low levels of severity did not report higher means in the total scores or domains of CPQ(11-14). CONCLUSION: The presence of tooth erosion of low severity did not have a significant negative impact on the children's perception of oral health or on their daily performance.

Preliminary validation of the Brazilian version of the Child Perceptions Questionnaire 8-10.

AIM: The aim of the study was to perform a preliminary validation of the Brazilian version of the Child Perceptions Questionnaire 8-10 (CPQ 8-10). METHODS: The sample used to test the measurement equivalence was made up of 59 children from 8 to 10 years of age at the Federal University of Minas Gerais, Brazil. The CPQ 8-10 was administered, and clinical exams were performed by a single examiner, calibrated for the diagnosis of dental caries (Kappa= 0.98) and malocclusion (weighted Kappa and intraclass correlation coefficient = 0.66-1.00). The children were divided into three groups according to their clinical condition (22 with cavitated carious lesions; 20 with malocclusion; 17 with both oral conditions). STATISTICS: The internal consistency of the instrument was assessed by Cronbach's alpha Coefficient. The Intraclass correlation coefficient (ICC) was used for the test-retest reliability (40 children). Discriminant validity was determined using the Kruskal-Wallis test. RESULTS: An assessment of the psychometric properties revealed the instrument to be reliable (Cronbach's alpha=0.92 for the total scale and 0.63-0.85 for the subscales), exhibiting excellent stability (ICC=0.96 for the total scale and 0.79-0.95 for the subscales). Construct validity was demonstrated through the significant correlations between the global indicators and subscales. There were statistically significant differences between the clinical groups regarding the total scale, thereby demonstrating discriminant validity (p=0.03). CONCLUSIONS: The preliminary validation of the Brazilian version of the CPQ 8-10 showed valid and reliable for use on Brazilian children.

Family Impact Scale (FIS): psychometric properties of the Brazilian Portuguese language version.

AIM: Evaluate the psychometric properties of the Brazilian version of the Family Impact Scale (FIS). METHODS: Following translation and cross-cultural adaptation, the FIS was tested on 123 parents-caregivers of children between 11 and 14 years of age with dental caries and malocclusions. The parents were recruited from the Paediatric Dental and Orthodontic clinics where their children were receiving dental care. Psychometric properties were assessed through internal consistency, test-retest reliability, construct validity and discriminant validity. RESULTS: The mean FIS score was 6.97 (SD 7.81) for the dental caries group and 7.25 (SD 7.70) for the malocclusion group. The FIS score was unable to discriminate different family impact caused by children's oral health conditions. Internal consistency was confirmed by a Cronbach's alpha coefficient of 0.79. Test-retest reliability revealed good reproducibility (ICC 0.83). Construct validity was good, demonstrating highly significant correlations between parent's perceptions regarding the overall wellbeing indicator for their children and the total FIS and subscales. Financial burden demonstrated no significant correlation with global indicators. CONCLUSIONS: Overall psychometric results for the Brazilian version of the FIS confirm it as a reliable, valid questionnaire for assessing the family impact caused by children's oral conditions.

Relationship between mothers' sense of coherence and oral health status of preschool children.

OBJECTIVE: The aim of the present study was to investigate the relationship between mothers' sense of coherence (SOC) and oral health status in a representative sample of 5-year-old preschool children. METHODS: A cross-sectional study was conducted in Belo Horizonte (Brazil) on a sample of 546 mothers and their 5-year-old children, randomly selected from preschools. Data were collected through questionnaires (mothers), the short version of Antonovsky's SOC scale (SOC-13) and clinical dental examinations (children). Simple and multiple logistic regression analyses were performed on the data. The following 8 outcome variables were selected: dental caries, filled and missing teeth, dental pulp exposure due to caries, dental root fragment, visible plaque, gingivitis and supragingival calculus. The examination was carried out by 2 trained, calibrated examiners. RESULTS: Mothers with a lower SOC were more likely to have children with decayed teeth (OR = 1.59, 95% CI = 1.01-2.29), dental pulp exposure (OR = 1.99, 95% CI = 1.06-3.77) or filled teeth (OR = 1.85, 95% CI = 1.12-3.06) regardless of the child's social class and gender. CONCLUSION: The data indicate that mothers' SOC is an important psychosocial determinant of the oral health status among preschool children.

Observation of the suppression of the flux of cosmic rays above 4 x 10 (19) eV.

The energy spectrum of cosmic rays above 2.5 x 10;{18} eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the particle flux, J proportional, variantE;{-gamma}, at energies between 4 x 10;{18} eV and 4 x 10;{19} eV is 2.69+/-0.02(stat)+/-0.06(syst), steepening to 4.2+/-0.4(stat)+/-0.06(syst) at higher energies. The hypothesis of a single power law is rejected with a significance greater than 6 standard deviations. The data are consistent with the prediction by Greisen and by Zatsepin and Kuz'min.

Upper limit on the diffuse flux of ultrahigh energy tau neutrinos from the Pierre Auger Observatory.

The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau neutrinos that interact in Earth's crust. Tau leptons from nu(tau) charged-current interactions can emerge and decay in the atmosphere to produce a nearly horizontal shower with a significant electromagnetic component. The data collected between 1 January 2004 and 31 August 2007 are used to place an upper limit on the diffuse flux of nu(tau) at EeV energies. Assuming an E(nu)(-2) differential energy spectrum the limit set at 90% C.L. is E(nu)(2)dN(nu)(tau)/dE(nu)<1.3 x 10(-7) GeV cm(-2) s(-1) sr(-1) in the energy range 2 x 10(17) eV< E(nu)< 2 x 10(19) eV.
