Socioeconomic and psychosocial predictors of dental healthcare use among Brazilian preschool children

Abstract Background Disparities in utilization of oral healthcare services have been attributed to socioeconomic and individual behavioral factors. Parents’ socioeconomic status, demographics, schooling, and perceptions of oral health may influence their children’s use of dental services. This cross-sectional study assessed the relationships between socioeconomic and psychosocial factors and the utilization of dental health services by children aged 1–5 years. Methods Data were collected through clinical exams and a structured questionnaire administered during the National Day of Children’s Vaccination. A Poisson regression model was used to estimate prevalence ratios and 95% confidence intervals. Results Data were collected from a total of 478 children. Only 112 (23.68%) were found to have visited a dentist; 67.77% of those had seen the dentist for preventive care. Most (63.11%) used public rather than private services. The use of dental services varied according to parental socioeconomic status; children from low socioeconomic backgrounds and those whose parents rated their oral health as “poor” used dental services less frequently. The reason for visiting the dentist also varied with socioeconomic status, in that children of parents with poor socioeconomic status and who reported their child’s oral health as “fair/poor” were less likely to have visited the dentist for preventive care. Conclusion This study demonstrated that psychosocial and socioeconomic factors are important predictors of the utilization of dental care services.

Dynamics of follicular growth and progesterone concentrations in cyclic and anestrous suckling Nelore cows (Bos indicus) treated with progesterone, equine chorionic gonadotropin, or temporary calf removal

The objective of this study was to investigate the effects of eCG and temporary calf removal (TCR) associated with progesterone (P4) treatment on the dynamics of follicular growth, CL size, and P4 concentrations in cyclic (n ¼ 36) and anestrous (n ¼ 30) Nelore cows. Cyclic (C) and anestrous (A) cows were divided into three groups. The control group received 2 mg of estradiol benzoate via intramuscular (IM) injection and an intravaginal device containing 1.9 g of P4 on Day 0. On Day 8, the device was removed, and the animals received 12.5 mg of dinoprost tromethamine IM. After 24 hours, the animals received 1 mg of estradiol benzoate IM. In the eCG group, cows received the same treatment described for the control group but also received 400 UI of eCG at the time of device removal. In the TCR group, calves were separated from the cows for 56 hours after device removal. Ultrasound exams were performed every 24 hours after device removal until the time of ovulation and 12 days after ovulation to measure the size of the CL. On the same day as the CL measurement, blood was collected to determine the plasma P4 level. Statistical analyses were performed with a significance level of P ≤ 0.05. In cyclic cows, the presence of the CL at the beginning of protocol resulted in a smaller follicle diameter at the time of device removal (7.4 ± 0.3 mm in cows with CL vs. 8.9 ± 0.4 mm in cows without CL; P ¼ 0.03). All cows ovulated within 72 hours after device removal. Anestrous cows treated with eCG or TCR showed follicle diameter at fixed-timed artificial insemination (A-eCG 10.2 ± 0.3 and A-TCR 10.3 ± 0.5 mm) and follicular growth rate (A-eCG 1.5 ± 0.2 and A-TCR 1.3 ± 0.1 mm/day) similar to cyclic cows (C-eCG 11.0 ± 0.6 and C-TCR 12.0 ± 0.5 mm) and (C-eCG 1.4 ± 0.2 and C-TCR 1.6 ± 0.2 mm/day, respectively; P ≤ 0.05). Despite the similarities in CL size, the average P4 concentration was higher in the A-TCR (9.6 ± 1.4 ng/mL) than in the A-control (4.0 ± 1.0 ng/mL) and C-TCR (4.4 ± 1.0 ng/mL) groups (P < 0.05). From these results, we conclude that eCG treatment and TCR improved the fertility of anestrous cows by providing follicular growth rates and size of dominant follicles similar to cyclic cows. Additionally, TCR increases the plasma concentrations of P4 in anestrous cows

Stato sanitario di Spigole (Dicentrarchus Labrax) ed Orate (Sparus Aurata) allevate in Grecia e in Italia in relazione alla presenza di agenti di Zoonosi ed Ectoparassiti patogeni

Le attività di ricerca della presente tesi di dottorato si sono focalizzata principalmente sulla parassitofauna dei pesci marini allevati in Grecia ed in Italia con particolare attenzione allo studio degli ectoparassiti di maggior rilievo sanitario in maricoltura ed alla ricerca di endoparassiti di potenziale interesse zoonosico, in particolare larve di nematodi Anisakidae del genere Anisakis. Nel corso del triennio sono stati sottoposti ad esami parassitologici 916 spigole (Dicentrarchus labrax) e 462 orate (Sparus aurata) prelevate presso diverse tipologie di allevamenti greci ed italiani. Per quanto concerne le spigole, la presenza di ectoparassiti è stata riscontrata nel 29,2% e nel 61,9% dei soggetti provenienti rispettivamente da impianti siti in Grecia ed in Italia, mentre le orate hanno presentato percentuali di positività rispettivamente del 87,5% e del 26,7%. Gli ectoparassiti dominanti sono risultati essere il monogeneo Diplectanum aequans nelle spigole ed il ciliato Cryptocaryon irritans e il monogeneo Furnestinia echeneis nelle orate, sebbene sia stato possibile studiare anche il coinvolgimento di altri ectoparassiti, quali il monogeneo Sparicotyle chrysophrii ed il dinoflagellato Amyloodinium ocellatum, nel determinismo di alcuni episodi morbosi. Le osservazioni istopatologiche hanno permesso di caratterizzare le lesioni causate dagli ectoparassiti a diverse intensità d’infestazione. Per quanto concerne la ricerca di parassiti zoonosici, con particolare riferimento agli stadi larvali di nematodi Anisakidae del genere Anisakis, si sono condotti esami parassitologici a livello di cavità viscerale e di muscolo laterale in tutti i soggetti provenienti da allevamenti in gabbia (626 soggetti, di cui 441 spigole e 185 orate). Tutti i soggetti esaminati sono risultati negativi, indicando come il rischio di infestazione da larve di nematodi anisakidi possa essere considerato trascurabile in spigole ed orate allevate in gabbia, come già dimostrato per il salmone atlantico (EFSA, 2010).

Problemi di consolidamento di matrici lapidee di differente microstruttura esposte a sollecitazioni ambientali e microclimatiche di varia origine

Questa ricerca presenta i risultati di una indagine volta a verificare la reale efficacia di rinforzo corticale su rocce carbonatiche di differenti caratteristiche mineralogiche, utilizzando consolidanti inorganici in soluzione acquosa quali l’Ossalato Ammonico (AmOX) e il Diammonio Fosfato Acido (DAHP). Le matrici carbonatiche scelte sono quelle del marmo invecchiato e una biomicrite. Sui campioni sono state effettuate indagini (SEM,MIP,XRD,MO,TG-DTA) di caratterizzazione prima e dopo i trattamenti volte a valutare eventuali effetti di rinforzo e misure fisiche di suscettività all’acqua. L’efficacia dei consolidanti inorganici è stata comparata con diversi consolidanti organici e ibridi presenti in commercio ed utilizzati in ambito conservativo. L'efficacia si è mostrata fortemente legata al fabric del materiale e alle modalità di strutturazione del prodotto di neomineralizzazione all’interno della compagine deteriorata. Nel caso del trattamento con AmOx il soluzione acquosa al 4%, la whewellite è l’unica fase di neoformazione riscontrata; la sua crescita avviene con un meccanismo essenzialmente topochimico. Nei materiali carbonatici compatti si possono ottenere solo modesti spessori di coating di neoformazione; per le rocce porose, contenenti difetti come lesioni, pori o micro-fratture, l’efficacia del trattamento può risultare più incisiva. Questo trattamento presenta lo svantaggio legato alla rapidissima formazione dei cristalli di whewellite che tendono a passivare le superfici impedendo la progressione della reazione; il vantaggio è connesso alla facile applicazione in cantiere. Nel caso del DAHP sulla matrice carbonatica trattata, si formano cluster cristallini contenenti specie più o meno stabili alcune riconducibili all’idrossiapatite. La quantità e qualità delle fasi, varia fortemente in funzione della temperatura, pH, pressione con conseguenze interferenza nelle modalità di accrescimento dei cristalli. Il trattamento alla stato attuale appare comunque di notevole interesse ma allo stesso tempo difficilmente applicabile e controllabile nelle reali condizioni operative di un cantiere di restauro.

Longitudinal evolution of cognitive functions in patients with multiple system atrophy: a prospective study

Introduction and Background: Multiple system atrophy (MSA) is a sporadic, adult-onset, progressive neurodegenerative disease characterized clinically by parkinsonism, cerebellar ataxia, and autonomic failure. We investigated cognitive functions longitudinally in a group of probable MSA patients, matching data with sleep parameters. Patients and Methods: 10 patients (7m/3f) underwent a detailed interview, a general and neurological examination, laboratory exams, MRI scans, a cardiovascular reflexes study, a battery of neuropsychological tests, and video-polysomnographic recording (VPSG). Patients were revaluated (T1) a mean of 16±5 (range: 12-28) months after the initial evaluation (T0). At T1, the neuropsychological assessment and VPSG were repeated. Results: The mean patient age was 57.8±6.4 years (range: 47-64) with a mean age at disease onset of 53.2±7.1 years (range: 43-61) and symptoms duration at T0 of 60±48 months (range: 12-144). At T0, 7 patients showed no cognitive deficits while 3 patients showed isolated cognitive deficits. At T1, 1 patient worsened developing multiple cognitive deficits from a normal condition. At T0 and T1, sleep efficiency was reduced, REM latency increased, NREM sleep stages 1-2 slightly increased. Comparisons between T1 and T0 showed a significant worsening in two tests of attention and no significant differences of VPSG parameters. No correlation was found between neuropsychological results and VPSG findings or RBD duration. Discussion and Conclusions: The majority of our patients do not show any cognitive deficits at T0 and T1, while isolated cognitive deficits are present in the remaining patients. Attention is the cognitive function which significantly worsened. Our data confirm the previous findings concerning the prevalence, type and the evolution of cognitive deficits in MSA. Regarding the developing of a condition of dementia, our data did not show a clear-cut diagnosis of dementia. We confirm a mild alteration of sleep structure. RBD duration does not correlate with neuropsychological findings.

Le disfluenze e la percezione degli ascoltatori. Valutazione di tre interpretazioni consecutive.

This study aims at exploring listeners’ perception of disfluencies, i.e. ungrammatical pauses, filled pauses, repairs, false starts and repetitions, which can irritate listeners and impede comprehension. As professional communicators, conference interpreters should be competent public speakers. This means that their speech should be easily understood by listeners and not contain elements that may be considered irritating. The aim of this study was to understand to what extent listeners notice disfluencies and consider them irritating, and to examine whether there are differences between interpreters and non-interpreters and between different age groups. A survey was therefore carried out among professional interpreters, students of interpreting and people who regularly attend conferences. The respondents were asked to answer a questionnaire after listening to three speeches: three consecutive interpretations delivered during the final exams held at the Advanced School of Languages, Literature, Translation and Interpretation (SSLLTI) in Forlì. Since conference interpreters’ public speaking skills should be at least as good as those of the speakers at a conference, the speeches were presented to the listeners as speeches delivered during a conference, with no mention of interpreting being made. The study is divided into five chapters. Chapter I outlines the characteristics of the interpreter as a professional communicator. The quality criterion “user-friendliness” is explored, with a focus on features that make a speech more user-friendly: fluency, intonation, coherence and cohesion. The Chapter also focuses on listeners’ quality expectations and evaluations. In Chapter II the methodology of the study is described. Chapter III contains a detailed analysis of the texts used for the study, focusing on those elements that may irritate listeners or impede comprehension, namely disfluencies, the wrong use of intonation and a lack of coherence or cohesion. Chapter IV outlines the results of the survey, while Chapter V presents our conclusions.

A novel marker for heart failure: Cross sectional area assessment in a large vein by conductance catheter.

The present study investigates the feasibility of a new application able to check the heart failure status in a patient through the estimation of the venous distension. In this way it would be possible to follow up patients, avoiding invasive or expensive exams such as cardiac catheterization and echocardiography. Moreover, the devices would also be able to diagnose the decline of the disease, in order to allow a new adaptation to therapy, and vice versa to check the improvement in the patient’s conditions after the CRT device implant. This thesis is essentially divided into three parts: an analytical model was used to obtain an estimation of the error committed for the calculation of the CSA and to understand how the accuracy and sensitivity depend on the different configurations of the electrodes and the catheter position inside the vein; secondly, an in-vitro experiment was carried out in order to verify the practical feasibility for these kinds of measurements, in a very simplified model; in the end, several animal experiments were done to test the in-vivo practicability of the proposed method. The obtained results showed the feasibility of this approach. In fact, the error committed in the estimation of CSA, during the animal experiments, can be considered acceptable (CSAerror_max ≈ -14%). Moreover, it has been demonstrated that the conductance catheter allows assessing, not only the vein CSA, but also the breathing of the animal.

Rarely selected distractors in high stakes medical multiple-choice examinations and their recognition by item authors: A simulation and survey

Background Many medical exams use 5 options for multiple choice questions (MCQs), although the literature suggests that 3 options are optimal. Previous studies on this topic have often been based on non-medical examinations, so we sought to analyse rarely selected, 'non-functional' distractors (NF-D) in high stakes medical examinations, and their detection by item authors as well as psychometric changes resulting from a reduction in the number of options. Methods Based on Swiss Federal MCQ examinations from 2005-2007, the frequency of NF-D (selected by <1% or <5% of the candidates) was calculated. Distractors that were chosen the least or second least were identified and candidates who chose them were allocated to the remaining options using two extreme assumptions about their hypothetical behaviour: In case rarely selected distractors were eliminated, candidates could randomly choose another option - or purposively choose the correct answer, from which they had originally been distracted. In a second step, 37 experts were asked to mark the least plausible options. The consequences of a reduction from 4 to 3 or 2 distractors - based on item statistics or on the experts' ratings - with respect to difficulty, discrimination and reliability were modelled. Results About 70% of the 5-option-items had at least 1 NF-D selected by <1% of the candidates (97% for NF-Ds selected by <5%). Only a reduction to 2 distractors and assuming that candidates would switch to the correct answer in the absence of a 'non-functional' distractor led to relevant differences in reliability and difficulty (and to a lesser degree discrimination). The experts' ratings resulted in slightly greater changes compared to the statistical approach. Conclusions Based on item statistics and/or an expert panel's recommendation, the choice of a varying number of 3-4 (or partly 2) plausible distractors could be performed without marked deteriorations in psychometric characteristics.

"Drug mules" as a radiological challenge: Sensitivity and specificity in identifying internal cocaine in body packers, body pushers and body stuffers by computed tomography, plain radiography and Lodox

PURPOSE: The purpose of our study was to retrospectively evaluate the specificity, sensitivity and accuracy of computed tomography (CT), digital radiography (DR) and low-dose linear slit digital radiography (LSDR, Lodox(®)) in the detection of internal cocaine containers. METHODS: Institutional review board approval was obtained. The study collectively consisted of 83 patients (76 males, 7 females, 16-45 years) suspected of having incorporated cocaine drug containers. All underwent radiological imaging; a total of 135 exams were performed: nCT=35, nDR=70, nLSDR=30. An overall calculation of all "drug mules" and a specific evaluation of body packers, pushers and stuffers were performed. The gold standard was stool examination in a dedicated holding cell equipped with a drug toilet. RESULTS: There were 54 drug mules identified in this study. CT of all drug carriers showed the highest diagnostic accuracy 97.1%, sensitivity 100% and specificity 94.1%. DR in all cases was 71.4% accurate, 58.3% sensitive and 85.3% specific. LSDR of all patients with internal cocaine was 60% accurate, 57.9% sensitive and 63.4% specific. CONCLUSIONS: CT was the most accurate test studied. Therefore, the detection of internal cocaine drug packs should be performed by CT, rather than by conventional X-ray, in order to apply the most sensitive exam in the medico-legal investigation of suspected drug carriers. Nevertheless, the higher radiation applied by CT than by DR or LSDR needs to be considered. Future studies should include evaluation of low dose CT protocols in order to address germane issues and to reduce dosage.

The Permanent Income Hypothesis: A Test on Czech Privatisation

Since the late eighties, economists have been regarding the transition from command to market economies in Central and Eastern Europe with intense interest. In addition to studying the transition per se, they have begun using the region as a testing ground on which to investigate the validity of certain classic economic propositions. In his research, comprising three articles written in English and totalling 40 pages, Mr. Hanousek uses the so-called "Czech national experiment" (voucher privatisation scheme) to test the permanent income hypothesis (PIH). He took as his inspiration Kreinin's recommendation: "Since data concerning the behaviour of windfall income recipients is relatively scanty, and since such data can constitute an important test of the permanent income hypothesis, it is of interest to bring to bear on the hypothesis whatever information is available". Mr. Hanousek argues that, since the transfer of property to Czech citizens from 1992 to 1994 through the voucher scheme was not anticipated, it can be regarded as windfall income. The average size of the windfall was more than three month's salary and over 60 percent of the Czech population received this unexpected income. Furthermore, there are other reasons for conducting such an analysis in the Czech Republic. Firstly, the privatisation process took place quickly. Secondly, both the economy and consumer behaviour have been very stable. Thirdly, out of a total population of 10 million Czech citizens, an astonishing 6 million, that is, virtually every household, participated in the scheme. Thus Czech voucher privatisation provides a sample for testing the PIH almost equivalent to a full population, thus avoiding problems with the distribution of windfalls. Compare this, for instance with the fact that only 4% of the Israeli urban population received personal restitution from Germany, while the number of veterans who received the National Service Life Insurance Dividends amounted to less than 9% of the US population and were concentrated in certain age groups. But to begin with, Mr. Hanousek considers the question of whether the public percieves the transfer from the state to individual as an increase in net wealth. It can be argued that the state is only divesting itself of assets that would otherwise provide a future source of transfers. According to this argument, assigning these assets to individuals creates an offsetting change in the present value of potential future transfers so that individuals are no better off after the transfer. Mr. Hanousek disagrees with this approach. He points out that a change in the ownership of inefficient state-owned enterprises should lead to higher efficiency, which alone increases the value of enterprises and creates a windfall increase in citizens' portfolios. More importantly, the state and individuals had very different preferences during the transition. Despite government propaganda, it is doubtful that citizens of former communist countries viewed government-owned enterprises as being operated in the citizens' best interest. Moreover, it is unlikely that the public fully comprehended the sophisticated links between the state budget, state-owned enterprises, and transfers to individuals. Finally, the transfers were not equal across the population. Mr. Hanousek conducted a survey on 1263 individuals, dividing them into four monthly earnings categories. After determining whether the respondent had participated in the voucher process, he asked those who had how much of what they received from voucher privatisation had been (a) spent on goods and services, (b) invested elsewhere, (c) transferred to newly emerging pension funds, (d) given to a family member, and (e) retained in their original form as an investment. Both the mean and the variance of the windfall rise with income. He obtained similar results with respect to education, where the mean (median) windfall for those with a basic school education was 13,600 Czech Crowns (CZK), a figure that increased to 15,000 CZK for those with a high school education without exams, 19,900 CZK for high school graduates with exams, and 24,600 CZK for university graduates. Mr. Hanousek concludes that it can be argued that higher income (and better educated) groups allocated their vouchers or timed the disposition of their shares better. He turns next to an analysis of how respondents reported using their windfalls. The key result is that only a relatively small number of individuals reported spending on goods. Overall, the results provide strong support for the permanent income hypothesis, the only apparent deviation being the fact that both men and women aged 26 to 35 apparently consume more than they should if the windfall were annuitised. This finding is still fully consistent with the PIH, however, if this group is at a stage in their life-cycle where, without the windfall, they would be borrowing to finance consumption associated with family formation etc. Indeed, the PIH predicts that individuals who would otherwise borrow to finance consumption would consume the windfall up to the level equal to the annuitised fraction of the increase in lifetime income plus the full amount of the previously planned borrowing for consumption. Greater consumption would then be financed, not from investing the windfall, but from avoidance of future repayment obligations for debts that would have been incurred without the windfall.

Effective Practice and Experiential Education

The central challenge to educators in the liberal arts as in all areas of study is transfer of learning i.e. how can we design learning environments and instruction to that students will be able to use what they learn in appropriate new contexts? Alfred North Whitehead described this as the problem of ‘inert knowledge’ nearly a century ago and Dewey noted that instruction which helps students reproduce what is studied on exams might not produce the depth of understanding that allows for recognizing the relevance of what is known to a particular situation and the ability to apply it. Knowledge that is not conditionalized (i.e. in which the learner does not know when where and why it is to be used) is inert.

Predictors of oral health quality of life in older adults

There is limited information regarding oral health status and other predictors of oral health-related quality of life. An association between oral health status and perceived oral health-related quality of life (OHQOL) might help clinicians motivate patients to prevent oral diseases and improve the outcome of some dental public health programs. This study evaluated the relationship between older persons' OHQOL and their functional dentition, caries, periodontal status, chronic diseases, and some demographic characteristics. A group of 733 low-income elders (mean age 72.7 [SD = 4.71, 55.6% women, 55.1% members of ethnic minority groups in the U.S. and Canada) enrolled in the TEETH clinical trial were interviewed and examined as part of their fifth annual visit for the trial. OHQOL was measured by the Geriatric Oral Health Assessment Index (GOHAI); oral health and occlusal status by clinical exams and the Eichner Index; and demographics via interviews. Elders who completed the four-year assessment had an average of 21.5 teeth (SD = 6.9), with 8.5 occluding pairs (SD = 4.6), and 32% with occlusal contacts in all four occluding zones. Stepwise multiple regressions were conducted to predict total GOHAI and its subscores (Physical, Social, and Worry). Functional dentition was a less significant predictor than ethnicity and being foreign-born. These variables, together with gender, years since immigrating, number of carious roots, and periodontal status, could predict 32% of the variance in total GOHAI, 24% in Physical, 27% in Social, and 21% in the Worry subscales. These findings suggest that functional dentition and caries influence older adults' OHQOL, but that ethnicity and immigrant status play a larger role.

Effects of instructional changes on student learning of electrochemistry in an IB chemistry course

This study investigated the effectiveness of incorporating several new instructional strategies into an International Baccalaureate (IB) chemistry course in terms of how they supported high school seniors’ understanding of electrochemistry. The three new methods used were (a) providing opportunities for visualization of particle movement by student manipulation of physical models and interactive computer simulations, (b) explicitly addressing common misconceptions identified in the literature, and (c) teaching an algorithmic, step-wise approach for determining the products of an aqueous solution electrolysis. Changes in student understanding were assessed through test scores on both internally and externally administered exams over a two-year period. It was found that visualization practice and explicit misconception instruction improved student understanding, but the effect was more apparent in the short-term. The data suggested that instruction time spent on algorithm practice was insufficient to cause significant test score improvement. There was, however, a substantial increase in the percentage of the experimental group students who chose to answer an optional electrochemistry-related external exam question, indicating an increase in student confidence. Implications for future instruction are discussed.

Reproducibility of dGEMRIC in assessment of hip joint cartilage: a prospective study

PURPOSE: To investigate the reproducibility of dGEMRIC in the assessment of cartilage health of the adult asymptomatic hip joint. MATERIALS AND METHODS: Fifteen asymptomatic volunteers (mean age, 26.3 years +/- 3.0) were preliminarily studied. Any volunteer that was incidentally diagnosed with damaged cartilage on MRI (n = 5) was excluded. Ten patients that had no evidence of prior cartilage damage (mean age, 26.2 years +/- 3.4) were evaluated further in this study. The reproducibility of dGEMRIC was assessed with two T1(Gd) exams performed 4 weeks apart in these volunteers. The protocol involved an initial standard MRI to confirm healthy cartilage, which was then followed by dGEMRIC. The second scan included only the repeat dGEMRIC. Region of interest (ROI) analyses for T1(Gd)-measurement was performed in seven radial reformats. Statistical analysis included the student's t-test and intra-class correlation (ICC) measurement to assess reproducibility. RESULTS: Overall 70 ROIs were studied. Mean cartilage T1(Gd) values at various loci ranged from 560.9 ms to 684.4 ms at the first set of readings and 551.5 ms to 662.2 ms in the second one. The mean difference per region of interest between the two T1(Gd)-measurements ranged from 21.4 ms (3.7%) to 45.0 ms (6.8%), which was not found to be statistically significant (P = 0.153). There was a high reproducibility detected (ICC range, 0.667-0.915). Intra- and Inter-observer analyses proved a high agreement for T1(Gd) assessment (0.973 and 0.932). CONCLUSION: We found dGEMRIC to be a reliable tool in the assessment of cartilage health status in adult hip joints.
