Microstrain Around Dental Implants Supporting Fixed Partial Prostheses Under Axial and Non-Axial Loading Conditions, In Vitro Strain Gauge Analysis

The current study used strain gauge analysis to perform an in vitro evaluation of the effect of axial and non-axial loading on implant-supported fixed partial prostheses, varying the implant placement configurations and the loading points. Three internal hexagon implants were embedded in the center of each polyurethane block with in-line and offset placements. Microunit abutments were connected to the implants using a torque of 20 N.cm, and plastic prosthetic cylinders were screwed onto the abutments, which received standard patterns cast in Co-Cr alloy (n = 10). Four strain gauges (SGs) were bonded onto the surfaces of the blocks, tangentially to the implants: SG 01 mesially to implant 1, SG 02 and SG 03 mesially and distally to implant 2, respectively, and SG 04 distally to implant 3. Each metallic structure was screwed onto the abutments using a 10-N.cm torque, and axial and non-axial loads of 30 kg were applied at 5 predetermined points. The data obtained from the strain gauge analyses were analyzed statistically through the repeated measures analysis of variance and the Tukey test, with a conventional level of significance of P < 0.05. The results showed a statistically significant difference for the loading point (P = 0.0001), with point E (nonaxial) generating the highest microstrain (327.67 mu epsilon) and point A (axial) generating the smallest microstrain (208.93 mu epsilon). No statistically significant difference was found for implant placement configuration (P = 0.856). It was concluded that the offset implant placement did not reduce the magnitude of microstrain around the implants under axial and non-axial loading conditions, although loading location did influence this magnitude.

Indicadores de stress e sobrecarga em cuidadores formais e informais de pacientes oncológicos

The present study aimed to identify the presence of indicators of stress, levels of stress and overload with the formal and informal caregivers of cancer patients. Participated in the survey 33 caregivers of cancer patients in total, 16 formal and 17 informal. To collect data, we used: 1) Roadmap for characterization of participants; 2) Inventory of Stress Symptoms Lipp - ISSL and 3) Protocol Zarit Burden Interview - ZBT. The results revealed that 43 % of informal carers were in the resistance phase, 29 % in the burnout stage, 14 % at the stage of exhaustion and almost 14 % in the alert phase. Formal caregivers 25 % are in the exhaustion phase and 75 % in the resistance. The overload has also performed on a larger scale in informal than formal caregivers, 47 % to 18,7 % charge respectively. However, the results revealed no statistically significant difference between groups for the incidence of stress but indicated a difference against overloading pointing out that professional caregivers in the incidence is lower. The results suggest the need to implement support for informal and formal caregivers programs, develop coping strategies, handling the situations of overload and stress, aiming to better quality of life for the caregiver, and consequently for the patient who is receiving care.

Processos de leitura em escolares com transtorno do déficit de atenção/hiperatividade

This study aimed to characterize and compare the performance of students with Attention Deficit Hyperactivity Disorder and students with good academic performance on the readingassessment processes. Forty students ranging from 8 years and 2 months old to 10 years and 11 months old, from both genders, from 1st to 4th grades of elementary level, participated inthis study, distributed in two groups: GI, with 20 students with interdisciplinary diagnosis ofAttention Deficit Hyperactivity Disorder (ADHD), and GII, 20 students with good academic performance,paired with GI according to gender, age and school level. The students wereassessedthrough the Brazilian adaptation of the Assessment Process of Reading – PROLEC, composedof four blocks: identification of letters, lexical, syntactic and semantic processes. Statisticallysignificant difference occurred between GI and GII in the PROLEC tests, with the exception of thesame-different and lexical decision tests, indicating that the students from GI presented inferior performance when compared with students from GII. Regarding the classification of the resultsof PROLEC, there was a statistically significant difference in the lexical, syntactic and semanticprocesses and the letter and sound test, with the exception of same-different tests of identificationof letters process. The findings suggests that the group of students with ADHD showsinferior performance compared to the group without disabilities, highlighting that the attentionfactor affects the cognitive functions impairing the acquisition of skills necessary for reading.

Avaliação do controle postural e do tipo do pé de pessoas com deficiência visual

The balance changing in the visually impaired is target of investigations, as balance and vision are interrelated. Also, another important factor in the maintenance of postural control is the biomechanical aspect of the feet. This study aimed to evaluate postural control and feet type of individuals with visual impairments. For then 17 adults with visual impairment participated in this study and have been evaluated by the baropodometry system. The oscillation of the center of pressure data were analyzed using the software Conformat Research 5.8, and subjected to Mann-Whitney’s statistical test. The results showed no statistically significant difference in postural control when comparing individuals with and without visual residue and which normal and foot with biomechanical alterations, which demonstrates that the visual impairment was the main factor of changes in postural control for the participants of this study.

Aplicação do modelo de tutoria em tarefas de leitura e escrita para criança com dislexia do desenvolvimento

Developmental dyslexia is characterized by impairment in reading and writing as a result of changes in the cognitive-linguistic behavior. The goal of the research was to analyze and compare the performance on tasks of reading and writing in children with developmental dyslexia after a mentoring program. Participated in this study 15 children of both genders from 3rd to 7th grade public schools of a city in the State of São Paulo, with average age (M = 9.4) and (DP = 1.08) divided into GIexperimental group (7 children who received intervention) and GII – control group (8 children did not receive the intervention, they were matched according to sex and age group with GI). The children were subjected to the diagnostic survey of reading and writing and to the intervention program in Reading Recovery tutoring. The data regarding reading and writing tasks related to mentoring program were collected in CEES-Centro de Estudos de Educação e Saúde da UNESP. The results revealed statistically significant difference between the GI and GII, where children with dyslexia in the GI showed superior performance on the task of reading words and reading the book I in relation to children of the GII. It was concluded that the GI introduced significant advances compared to GII that did not receive mentoring intervention, demonstrating that due to variability of cognitive-linguistic profile of children with dyslexia, it is necessary to develop, mainly, in the school context programs with specific difficulties that focus on interventions of this population.

Phase II clinical study of an association for the treatment of interstitial cystitis (CYSTEX)

Painful bladder syndrome associated with interstitial cystitis (PBS/IC) is a clinical condition characterized pelvic pain, urinary urgency, and urinary frequency. In this study, 22 patients were assigned to make two visits over a three weeks period. The patients were randomly, double-blinded assigned in two groups. The first group received Cystex® capsules. The second group received placebo capsules. Two capsules were taken three times a day away from meals. The change from baseline in the O’Leary-Sant IC symptom and problem index was the primary outcome parameter. Changes in functional bladder capacity and intensity of pain and urgency have been chosen as secondary outcome parameters. Mood as well as physical and sexual activity were rated by 10 questions on a scale 0 to 6. The ratings were analyzed and the average for each patient in both groups Cystex® and placebo was determined as the quality of life index. For the primary outcome there was a statistically significant difference between the groups. Mean symptom score-sum decreased from 28.4 to 20.5 in the Cystex® group compared with 29.5 to 26.8 in the placebo group (p<0.05). For the secondary end points, pain and urgency intensity improved statistically significantly in the Cystex® group compared with the placebo group (p<0.05). The frequency and functional bladder capacity improved to greater degree in the Cystex® group. The differences were statistically significant for comparison of frequency (p<0.05) and not for functional bladder capacity (p>0.05). In our study, Cystex® enhanced quality of life over the placebo showing a statistically significant. This trial have shown that the efficacy and safety of therapy with Cystex® in the treatment of interstitial cystitis and is an alternative for patients suffering from this pathology. Therefore, it can be concluded that the composition of Cystex®, increased the quality of life in treated patients.
