The effects of tooth loss on the anatomy of the maxilla]

OBJECTIVES: To compare prevalence rates of weight-control behaviors among adolescents with and without chronic illness and to explore the role of familial and other social factors on associations between disordered eating and chronic illness. DESIGN AND SETTING: Survey conducted in public schools in Connecticut. PARTICIPANTS: A representative statewide population-based sample of 9343 7th-, 9th-, and 11th-grade public school students, of whom 1021 reported a chronic illness. MAIN OUTCOME MEASURES: Disordered eating (vomiting, diet pills, and laxatives), dieting, and exercise for weight control; chronic illness status; family structure, family communication, parental caring, parental monitoring, parental expectations, peer support, and sexual and physical abuse. RESULTS: Adolescents with chronic illness were at greater risk for disordered eating than youth without chronic illness, after controlling for sociodemographic variables (girls: odds ratio, 1.59 [95% confidence interval, 1.19-2.14]; boys: odds ratio, 2.22 [95% confidence interval, 1.49-3.32]). Adolescents with chronic illness were less likely to come from 2-parent families; reported lower levels of family communication, parental caring, and parental expectations; and reported more sexual and physical abuse than youth without chronic illness. Male adolescents with chronic illness were more likely to report low peer support and low parental monitoring. Most of these familial-social factors were also associated with an increased prevalence of disordered eating. After familial-social factors were controlled for, however, associations between disordered eating and chronic illness remained statistically significant. CONCLUSIONS: Adolescents with chronic illness are at greater risk for disordered eating behaviors than youth without chronic illness. Factors other than the familial-social factors assessed in this study may be contributing to this increased risk. In the clinical setting, youth with chronic illness need to be screened for disordered eating and familial and other social concerns.     

The effects of BOTOX injections on emotional experience.

Although it was proposed over a century ago that feedback from facial expressions influence emotional experience, tests of this hypothesis have been equivocal. Here we directly tested this facial feedback hypothesis (FFH) by comparing the impact on self-reported emotional experience of BOTOX injections (which paralyze muscles of facial expression) and a control Restylane injection (which is a cosmetic filler that does not affect facial muscles). When examined alone, BOTOX participants showed no pre- to posttreatment changes in emotional responses to our most positive and negative video clips. Between-groups comparisons, however, showed that relative to controls, BOTOX participants exhibited an overall significant decrease in the strength of emotional experience. This result was attributable to (a) a pre- versus postdecrease in responses to mildly positive clips in the BOTOX group and (b) an unexpected increase in responses to negative clips in the Restylane control group. These data suggest that feedback from facial expressions is not necessary for emotional experience, but may influence emotional experience in some circumstances. These findings point to specific directions for future work clarifying the expression-experience relationship. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Dynamics of tooth loss In the adult population in Hungary

The authors examined the dental status of 9991 hungarian adult people and they drawn the conclusion of the tooth-loss dynamics of the '80-es. It has been found, that in comparison with international data the number of lost teeth was shaping unfavourable. Nevertheless the rate of completely edentate patients in all age-groups shows a favourable tendency.     

Contextualizing emotional exhaustion and positive emotional display: The signaling effects of supervisors’ emotional exhaustion and service climate.

In this study, we investigated how supervisors’ emotional exhaustion and service climate jointly influence the relationship between subordinates’ emotional exhaustion and their display of positive emotions at work. Using data from frontline sales employees and their immediate supervisors in a fashion retailer, we hypothesized and found that under the condition of a less positive service climate, subordinates’ emotional exhaustion was more negatively related to their positive emotional display when supervisors’ emotional exhaustion was higher rather than lower; this interaction effect of subordinates’ and supervisors’ emotional exhaustion was not significant in a more positive service climate. These results suggest that service climate and supervisors’ emotional exhaustion provide emotionally exhausted employees with important information cues about the possible availability of compensatory resources they need to uphold their efforts to display service-focused emotions.

The emotional impact of loss narratives: Event severity and narrative perspectives.

Out of the complex influences of event, narrative and listener characteristics on narrative emotions, this paper focuses on event severity, narrative perspectives, mood, and dispositions for emotion regulation and empathy. Event severity and perspective representation were systematically varied in sad autobiographical narratives to study their influence on quantity and quality of readers' emotional response. Each of three stories were manipulated to contain elaborated perspectives, only the past protagonists' perspective (dramatic narration), and very little perspectives at all (impersonal narration). We predicted that event severity influences the quantity of emotional response, while degree of perspective representation influences plausibility and whether emotional responses are sympathetic or interactional, that is, directed against the narrator. Hypotheses were confirmed except for plausibility, and perspective representation had an effect only on anger against and dislike of the narrator. In a second study, impersonal narration evoked anger at and negative evaluations of the narrator which were related to blaming the narrator for showing too little emotional involvement. The generalizability of findings across emotions and implications for sharing of emotions in everyday and clinical settings are discussed.

The predictability of periodontal treatment as measured by tooth loss: a retrospective study

OBJECTIVE: To analyse the validity of the Micraltest and Microbumintest semi-quantitative methods for microalbuminuria screening in type 2 diabetes mellitus in primary care clinics. DESIGN: Crossover study to validate diagnostic tests. SETTING: Three general practices at an urban health centre. PATIENTS: Consecutive sample of 64 diabetics not dependent on insulin. MEASUREMENTS AND MAIN RESULTS: Each patient's own doctor performed in the consultation the semi-quantitative determinations in a simple sample of the morning's first urine. As standard, a rate of albumin excretion above 20 micrograms/min, determined by immunonephelometry in a 2-hour controlled time sample, was used. The prevalence of Microalbuminuria was 25% (C.I. 95%, 14.4-35.6). The sensitivity of Micraltest was 69% (CI, 42-88), and its specificity 52% (CI, 37-67), corresponding to the cut-off point of 10 mg/L. The sensitivity of Microbumintest was 63% (CI, 36-84), and its specificity 67% (CI, 52-79). The combination of both tests in one sample had 75% sensitivity (CI, 47-92) and 44% specificity (CI, 30-59). Negative predictive values ranged between 84 and 85%. CONCLUSIONS: The semi-quantitative microalbuminuria detection tests are of limited use in the primary care clinic. Their sensitivity and the negative predictive value obtained in an isolated sample do not seem acceptable for a screening method.     

The effects of emotional behaviour on components of the respiratory cycle

Clinical guidelines can be viewed as generic skeletal-plan schemata that represent clinical procedural knowledge and that are instantiated and refined dynamically by care providers over significant time periods. In the Asgaard project, we are investigating a set of tasks that support the application of clinical guidelines by a care provider other than the guideline's designer. We are focusing on the application of the guideline, recognition of care providers' intentions from their actions, and critique of care providers' actions given the guideline and the patient's medical record. We are developing methods that perform these tasks in multiple clinical domains, given an instance of a properly represented clinical guideline and an electronic medical patient record. In this paper, we point out the precise domain-specific knowledge required by each method, such as the explicit intentions of the guideline designer (represented as temporal patterns to be achieved or avoided). We present a machine-readable language, called Asbru, to represent and to annotate guidelines based on the task-specific ontology. We also introduce an automated tool for the acquisition of clinical guidelines based on the same ontology, developed using the PROTEGE-II framework.

Longitudinal effects of emotional labour on emotional exhaustion and dedication of teachers.

A great number of teachers find teaching fulfilling and are dedicated to it, but others feel emotionally exhausted, indicating that the interaction with pupils can be emotionally demanding. Emotional labor was shown to play an important role for the health of teachers. In a full two-wave longitudinal study over the period of 1 year, the effect of emotional labor on emotional exhaustion and dedication of 102 teachers was investigated. Teachers who were able to influence their emotions to feel the emotion appropriate in a situation (so called deep acting) felt significantly less emotionally exhausted after 1 year. From this result, deep acting can, thus, be characterized as health-beneficial. Once teachers felt emotionally exhausted, they used more surface acting. More dedicated teachers, on the contrary, did neither engage more in deep acting nor in surface acting at Time 2. This indicates that those teachers who are dedicated to teaching seem less likely to act. To prevent emotional exhaustion of teachers, the development of interventions to promote health-beneficial emotional labor is necessary. This can be achieved by fostering deep acting, which reduces emotional exhaustion over longer periods of time. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Possible explanations for the tooth loss and cardiovascular disease relationship

Dynamics of proteins and membranes are usually investigated by red-edge excitation spectra and fluorescence anisotropy. In a viscous or rigid medium, the fluorescence maximum position changes with the excitation wavelength upon red-edge excitation. In addition to the shift in the emission maximum on red edge excitation, fluorescence anisotropy is also known to be dependent on the excitation and emission wavelengths in viscous media. However, this dependence has always been explained by the fact that the fluorophore is rigid, i.e. it does not display any residual motions. The aim of the present work was to check the validity of this latest assumption and to explain the possible origin of the dependence of the anisotropy on both the excitation and emission wavelengths. Therefore, we compared the results obtained from the fluorescence of the Trp residues of two alpha 1-acid glycoproteins (orosomucoid). One protein was purified by chromatographic methods (orosomucoid(c)) and the other was obtained with ammonium sulfate precipitation (orosomucoid(s)). Trp residues of orosomucoidc display free motions while those of orosomucoids are rigid. The general qualitative feature of the excitation anisotropy spectra recorded on both types of preparation is identical and resembles that obtained for other proteins containing tryptophan residue in protein. The fluorescence anisotropy measured across the emission spectra decreases for both preparations, indicating that this phenomenon is characteristic for fluorophores surrounded by a rigid microenvironment or by a microenvironment that displays motions. The fluorescence anisotropy variation across the emission and the excitation spectra is more important when the fluorophore possesses constrained motions than when it displays a high degree of freedom. Our results clearly demonstrate that the tertiary structure of the protein and the structure and dynamics of the microenvironments of the Trp residues are the origin of the dependence of anisotropy on the excitation and emission wavelengths.     

The effects of emotional content on reality-monitoring performance in young and older adults.

Reality monitoring refers to a person's ability to distinguish between perceived and imagined events. Prior research has demonstrated that young adults show a reality-monitoring advantage for negative arousing information as compared with neutral information. The present research examined whether this reality-monitoring benefit extends to positive information in young adults and whether older adults show a reality-monitoring advantage for emotional information of either valence. Two studies revealed no evidence for a reality-monitoring advantage for positive information; in both age groups, the reality-monitoring advantage existed only for negative information. Older adults were, however, more likely to remember that a positive item had been included on a study list than they were to remember that a nonemotional item had been studied. Young adults did not show this mnemonic enhancement for positive information. These results indicate that although older adults may show some mnemonic benefits for positive information (i.e., an enhanced ability to remember that a positive item was studied), they do not always show enhanced memory for source-specifying details of a positive item's presentation.

The effects of prior information on susceptibility to an emotional appeal.

"The hypothesis of this study was that persons who have received neutral information with respect to an object lower their evaluation of the object to a lesser extent after hearing an emotional appeal against it than persons who have not received such neutral information. The hypothesis was tested in an experiment done in high school classes, using an object with which the subjects had little or no prior acquaintance. The results confirmed the hypothesis."

Acute toxicological effects of ingested tooth whiteners in female rats

Tooth whiteners are considered as cosmetic agents to be used for bleaching teeth. Since tooth whitener may be swallowed during the whitening procedure, studies were conducted to determine whether ingestion of tooth whitener containing carbamide peroxide resulted in toxic effects. Adult female rats were used, and vaginal smears were examined daily to determine whether the animals were ovulating. Following an overnight fast, a single bolus of a commercial tooth whitener (5 g of tooth whitener/kg fasting body weight) was administered by gavage. Control rats received de-ionized water. After 2 h, mean respirations per min of animals receiving the tooth whitener Quik Start (contains 35% carbamide peroxide) decreased from 169 to 55, and body temperature decreased from 38.4 to 34 degrees C. Other distress signs included: labored breathing, loss of righting reflex, partial eye closure, bloody urine, and incontinence. Three of 22 animals (3/22) died within 48 h, of gastric hemorrhaging. Eight/10 rats stopped ovulating. At necropsy 2 weeks post-dosing, 10/19 animals had grossly bloated stomachs, and mucosal necrosis was observed histologically in 3. Animals receiving White & Brite or Nu-Smile (containing 10 or 15% carbamide peroxide, respectively) exhibited similar but milder symptoms. The data indicate that ingestion of large doses of commercial preparations of tooth whiteners may be acutely toxic, sometimes fatal, to female laboratory rats.     

Health effects of emotional disclosure in rheumatoid arthritis patients.

This study examined the effects of emotional disclosure of stressful events on the pain, physical and affective dysfunction, and joint condition of patients with rheumatoid arthritis (RA). Patients were randomly assigned to talk privately about stressful events (disclosure group, n?=?36) or about trivial topics (control group, n?=?36) for 4 consecutive days. Disclosure resulted in immediate increases in negative mood. At 2 weeks the 2 groups did not differ on any health measure, but at 3 months disclosure patients had less affective disturbance and better physical functioning in daily activities. There was no main effect of disclosure on pain or joint condition, but among the disclosure patients, those who experienced larger increases in negative mood after talking demonstrated improvements in the condition of their joints. This study concludes that, among RA patients, verbal disclosure and emotional processing of stressful life events induces an immediate negative mood followed by improved psychological functioning.

The effects of sleep loss on short-term recognition memory.

Compared the performance of 20 sleep-deprived undergraduates on a probe-recognition memory task with that of 20 nondeprived controls over periods up to 55 hrs. Recognition was either immediate or delayed by 20 sec. Results show that the sleep-deprived group made significantly more errors in the perception of the material, and under the delay condition retained less adequately those items correctly perceived. It is argued that these findings are consistent with the notion that sleep loss causes a deficit in attention, leading to misperception and a failure to rehearse adequately material presented for memorization.

A quantitative study of the emotional outcome of people caring for stroke survivors

BACKGROUND AND PURPOSE: Although the physical and, to a lesser extent, emotional outcome of stroke survivors has been well documented, there are far fewer data relating to the outcomes of those who care for them. We aimed to describe the outcome of those caring for stroke patients and to identify both patient and caregiver factors that are associated with poor caregiver outcomes. METHODS: As part of a randomized trial to evaluate a stroke family care worker, we identified 417 patients (67% of all referrals to our institution). We followed up 376 survivors of whom 246 identified a caregiver at a 6-month follow-up interview. The patients and caregivers were asked to complete 2 measures of emotional distress ( 30-item General Health Questionnaire [GHQ-30] and Hospital Anxiety and Depression [HAD] Scale). A regression analysis was used to identify factors that were independently associated with poor caregiver outcomes. RESULTS: Fifty-five percent of responding caregivers scored more than 4 on the GHQ-30, indicating that emotional distress is common in this group. Caregivers were more likely to be depressed if the patients were severely dependent (P<0.01) or emotionally distressed themselves (P<0.01). Female caregivers reported more anxiety (median HAD=8) than male caregivers (median HAD=5; P<0.01) but caregivers' levels of anxiety were not so clearly related to the patients' degree of physical disability as their levels of depression. Caregivers suffered more emotional distress if the patients had been dependent before their strokes. CONCLUSIONS: These data may help to identify those caregivers at greatest risk of poor emotional outcomes and thus help in the planning of trials and delivery of interventions aimed at preventing or treating distress among caregivers.     

The cracked tooth

Fractured molars and premolars are very common. Fractures usually result from cracks that develop and slowly extend until the tooth separates into buccal and lingual fragments. Sometimes, as these cracks expand, the patient exhibits symptoms of what is commonly referred to as "cracked tooth syndrome" (CTS). When CTS occurs, an opportunity exists to diagnose and treat these patients, to relieve their discomfort and prevent sequelae that would require more extensive treatment.     

The use of silicone dentures for edentulous patients

There are a number of occasions when a soft denture base will be of much more benefit to an edentulous patient than a conventional rigid prosthesis. This article discusses three such cases.     

The primacy of perceiving: Emotion recognition buffers negative effects of emotional labor.

There is ample empirical evidence for negative effects of emotional labor (surface acting and deep acting) on workers' well-being. This study analyzed to what extent workers' ability to recognize others' emotions may buffer these effects. In a 4-week study with 85 nurses and police officers, emotion recognition moderated the relationship between emotional labor and work engagement: Workers with high emotion recognition engaging in emotional labor did not report lower work engagement after 4 weeks, whereas those with low emotion recognition did. These effects pertained to both surface and deep acting. The results suggest that emotional labor be not necessarily detrimental to workers' engagement. Instead, the impact of emotional labor hinges upon workers' ability to correctly identify interaction partners' emotions. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
