Lipid profile of people with Diabetes mellitus type 2 and periodontal disease

The objective of this study was to evaluate improvement of lipids and periodontal disease in patients with type 2 Diabetes mellitus, by means of the relationship between blood levels of total cholesterol and its fractions, triglycerides and clinical periodontal parameters. Twenty patients, in age-range 18-70 years, were selected and divided into 2 groups: (1) conventional periodontal scaling and root planing + controlled mechanic; (2) conventional periodontal scaling and root planing + controlled mechanical + maintenance therapy. The analyses were performed on day 0, 180 and 720 days, including plaque index, gingival index, probing depth and clinical attachment level, and evaluation of total cholesterol and its fractions, and triglycerides. The 2 groups presented significant reduction in clinical periodontal parameters, however, probing depth did not diminish significantly only in Group 1. There was significant improvement in all blood parameters in both groups. It was concluded that after 720 days of the experiment, there were significant improvements in clinical and blood parameters, in general. The group that received maintenance therapy also showed a more expressive improvement in clinical periodontal parameters, in general, suggesting that this therapy is important and necessary in patients with type 2 Diabetes mellitus and periodontal disease.

The relationship between place BANA reactivity and clinical parameters in subjects with mental disabilities

The purpose of the present investigation was to determine whether subjects institutionalized with mental retardation have a relationship between periodontal clinical parameters and the presence of the BANA-positive periodontal pathogens Porphyromonas gingivalis, Treponema denticola, and Bacteroides forsythus in their subgingival plaques. Fifty institutionalized subjects (25 patients with Down syndrome and 25 subjects with mental retardation) were matched with respect to age and sex. Periodontal clinical parameters (Bleeding on Probing, BOP; Papillary Bleeding Score, PBS; and Probing Depth, PD) were obtained from 6 reference teeth (3, 8, 14, 19, 24, 30). In addition, subgingival plaque samples taken from the same 6 teeth were analyzed for the presence of the BANA-positive species, by means of the chairside BANA test. In both the patients with Down syndrome and the group with mental retardation, the presence of BANA-positive plaques was significantly associated with bleeding on probing (p < 0.05) and increased probing depth (p < 0.01, Chisquare). Analysis of these data indicated that the BANA test could be used in combination with clinical criteria to diagnose a periodontopathy anaerobic Infection in institutionalized subjects.

Effect of different exercise programs on the psychological and cognitive functions of people with Parkinson's disease

The purpose of this study was to analyze the effect of different exercise programs on the psychological and cognitive functions in patients with Parkinson's disease (PD). Forty-five patients with PD participated in the study. The participants were randomized in three intervention programs: Group-1 (n=15, cognitive-activities), Group-2 (n=15, multimodal exercise) and Group-3 (n=15, exercises for posture and gait). The clinical, psychological and cognitive functions were assessed before and after 4 months of intervention. Univariate analysis did not reveal significant interactions between groups and time (p>0.05). However, univariate analysis for time revealed differences in stress level and memory. Participants showed less physical stress (p<0.01) and overall stress (p < 0.04) and higher performance in episodic declarative memory (p < 0.001) after exercise. These findings suggest that group work with motor or non-motor activities can improve cognitive and psychological functions of patients with PD.

Do people with recurrent back pain constrain spinal motion during seated horizontal and downward reaching?

Background: Although the effect of symptomatic back pain on functional movement has been investigated, changes to spinal movement patterns in essentially pain-free people with a history of recurrent back pain are largely unreported. Reaching activities, important for everyday and occupational function, often present problems to such people, but have not been considered in this population. The purpose of this study was to compare the amplitude and timing of spinal and hip motions during two, seated reaching activities in people with and without a history of recurrent low back pain (RLBP).Methods: Spinal and hip motions during reaching downward and across the body, in both directions, were tracked using electromagnetic sensors. Analyses were conducted to explore the amplitudes, velocities and timings of 3D segmental movements and to compare controls with subjects with recurrent, but asymptomatic lumbar or lumbosacral pain.Findings: We detected significant differences in the amplitude and timing of movement in the lower thoracic region, with the RLBP group restricting movement and demonstrating compensatory increased motion at the hip. The lumbar region displayed no significant between-group differences. The order in which the spinal segments achieved peak velocity in cross-reaching was reversed in RLBP compared to controls, with lumbar motion leading in controls and lagging in RLBP.Interpretation: Subjects with a history of RLBP show a number of altered kinematic features during reaching activities which are not related to the presence or intensity of pain, but which suggest adaptive changes to movement control.

Positive effects of auditory cue in locomotor pattern of people with Parkinson's disease (off and on medication)

Gait disorders are identified in people with Parkinson’s disease. The aim of this study was to investigate the effect of auditory cues and medication on kinematic, kinetic and EMG parameters, during different gait phases of people with PD and healthy elderly. Thirty subjects distributed in two groups (Group 1, PD patients off and on medication; Group 2, healthy elderly) participated in this study and were instructed to walk in two experimental conditions: non-cued and cued. Therefore, kinematic, kinetic and electromyography analyses were utilized to investigate the locomotor pattern. Changes in locomotor pattern (greater muscular activity) with auditory cue were observed for PD patients. Regarding the medication, locomotor parameter improvement was observed after levodopa intake in association with the auditory cue. These results confirm the hypothesis about the external cues therapy that could be used as a complement to drug therapy to achieve improvement in the locomotor pattern of PD patients.

Auditory middle latency response and phonological awareness in students with learning disabilities

Introduction Behavioral tests of auditory processing have been applied in schools and highlight the association between phonological awareness abilities and auditory processing, confirming that low performance on phonological awareness tests may be due to low performance on auditory processing tests. Objective To characterize the auditory middle latency response and the phonological awareness tests and to investigate correlations between responses in a group of children with learning disorders. Methods The study included 25 students with learning disabilities. Phonological awareness and auditory middle latency response were tested with electrodes placed on the left and right hemispheres. The correlation between the measurements was performed using the Spearman rank correlation coefficient. Results There is some correlation between the tests, especially between the Pa component and syllabic awareness, where moderate negative correlation is observed. Conclusion In this study, when phonological awareness subtests were performed, specifically phonemic awareness, the students showed a low score for the age group, although for the objective examination, prolonged Pa latency in the contralateral via was observed. Negative weak to moderate correlation for Pa wave latency was observed, as was positive weak correlation for Na-Pa amplitude.

Comparison between common traffic lights and three types of traffic lights with visual cycle a safety and capacity analysis

The objective of this paper is compare the common traffic lights (CTL) to three different types of traffic lights with countdown displays (SCD) and assess their effects on road safety and capacity. This comparison is required because the results found in the literature are divergent among countries and cities, and one of the SCD analyzed in our study is different from the SCD used worldwide. An observational before-after study was conducted to evaluate the safety and capacity in a period of one year before and one year after the implementation of the SCD in three Brazilian cities. The results indicate that the SCD models 1 and 3 had around 35%±14% reduction in the total number of accidents; the model 2, does not have significant reduction. In order to perform the capacity analysis a framework for data collection and an adaptation for estimation of initial lost time in each phase were developed. Considering the capacity analysis there was a reduction around 11% in the lost time in SCD model 1, 7% in SCD model 2 and 3% in SCD model 3. However the implications of this on capacity are trifle due to a small increase in the average headways for all SCD models compare to CTL.

A equoterapia como auxiliar no processo de inclusão do aluno com deficiência visual: estudo de caso

This study examines the hippotherapy related to school inclusion. Inclusive education, given the diversity of human kind, seeks to understand and meet the educational needs of all students. Visual impairment is defined as a reduction or complete loss of ability to see with the better eye and after the best possible optical correction, and may be perceived by the focus when the individual educational needs of Braille for their learning. Hippotherapy is a therapeutic and educational method that uses the horse in an interdisciplinary approach in health, education and riding, searching for the biopsychosocial development of people with disabilities and/or special needs. The general objectives were: to follow a Hippotherapy program applied to a student with visual disabilities included in regular education from the practice sessions of hippotherapy and the student's school routine, and specific: to verify changes to a student with visual impairment during their participation in an equine therapy program, to check the commitment, involvement and interest in school activities the student practicing hippotherapy inserted into the regular school system. The methodology was a qualitative research, in the form of case study. The instruments of data collection were interviews, video recordings, photographs, school information and the subject of systematic observations of the sessions of hippotherapy. Interviews were conducted at three different times during the course of the program. First we used a strategy for succeeding in increasing the involvement of practicing with the school. Later, another strategy was established, consisting of the effective presence of the researcher in the school to carry out activities on the hippotherapy within the school environment. The analysis of the first interview showed no changes in school interest, however, occurred in the family environment. In analyzing the results of the second interview was seen as a...
