RESUMO

ABSTRACT Introduction: Acute cerebral infarction refers to the deficiency of the blood supply to the brain and the damage of tissue function. Objective: To study the effect of exercise training in early rehabilitation of patients with hemiplegia treated in the neurology department. Methods: Ninety-six patients with acute cerebral infarction hemiplegia were studied. According to the order of admission, 96 patients were divided into a control group and an early recovery group, with 48 patients in each group. Results: Before early rehabilitation, there was no statistical significance in NIHSS and FUGL-Meyer scores between the two groups (P > 0.05). After early rehabilitation,the NIHSS score of early rehabilitation group was lower than both its pre-early-rehab score and the control group score, while the FUGL-Meyer score was higher than both its pre-early-rehab and the control group score (P<0.05). Before early rehabilitation, there was no significant difference in the GQOLI-74 score between the two groups (P > 0.05). After early rehabilitation, the GQOLI-74 score was higher in the early rehabilitation group than both its pre-early-rehab score and the control group score (P<0.05). Conclusions: The clinical effect of early rehabilitation training in acute cerebral infarction patients with hemiplegia is significant and can further improve the clinical treatment of patients and their quality of life. Level of evidence II; Therapeutic studies - investigation of treatment results.

RESUMO

BACKGROUND: Automated peripheral mechanical stimulation (AMPS) has been proposed as a new complementary therapy with potential for improving motor and cardiovascular abnormalities in Parkinson's disease (PD). However, AMPS long-term effects and its combination with physical exercise are unknown. Thus, this study aims to compare the effects of a program of 12 weeks of physical exercise with a 12-week intervention program combining physical exercise and AMPS on the aerobic capacity, cardiac autonomic control, and gait parameters in patients with PD. METHODS: A randomized, controlled clinical trial will be conducted. Older volunteers with PD will be randomly assigned to one of the two groups studied: (1) exercise or (2) AMPS + exercise. Both groups will undergo an exercise program of 24 sessions, for 12 weeks, performed twice a week. Before exercise sessions, the group AMPS + exercise will receive a session of active AMPS, while the group exercise will receive an AMPS sham intervention. Shapiro-Wilk's and Levene's tests will be used to check for data normality and homogeneity, respectively. In case parametric assumptions are fulfilled, per-protocol and intention-to-treat analyses will be performed using a mixed model analysis of variance to check for group*time interaction. Significance level will be set at 5%. DISCUSSION: Several non-pharmacological treatment modalities have been proposed for PD, focusing primarily on the reduction of motor and musculoskeletal disorders. Regular exercise and motor training have been shown to be effective in improving quality of life. However, treatment options in general remain limited given the high prevalence and adverse impact of these disorders. So, developing new strategies that can potentiate the improvement of motor disabilities and also improve non-motor symptoms in PD is relevant. It is expected that the participants from both groups will improve their quality of life, gait parameters, and their cardiac autonomic control, with greater improvements being observed in the group combining active AMPS and physical exercise.

RESUMO

PURPOSE: To evaluate implant and prosthetic survival rates of full-arch rehabilitations retained by three implants in patients with edentulous mandibles. MATERIALS AND METHODS: This systematic review was developed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The focused question was: Are fixed mandibular 3-implant retained prostheses safe and predicable for full-arch mandibular prostheses? The Medline/PubMed and Cochrane Library databases were used to conduct the systematic search for clinical trials on fixed mandibular 3-implant retained prostheses published between 1999 and 2020. Only English-language studies that presented information on implant and prosthetic survival were included. RESULTS: A total of 302 studies were identified, of which 13 addressed the inclusion criteria. Additionally, 574 participants were included in these studies. As reported, 73 (4.57%) of 1596 implants failed, with a survival rate of 95.43%. In addition, the mean survival rate of the presented prostheses was 89.66%. The mean marginal bone loss was 1.09 mm. CONCLUSION: Within the limitations of the present review, implant and prosthetic survival rates of fixed mandibular 3-implant retained prostheses were similar to those of full-arch mandibular prostheses retained by four or more implants. Further research exploring the topic is necessary.

RESUMO

Se describe la evolución de una paciente con diagnóstico molecular de Epidermolisis Ampollar Distrófica Recesiva, quien a los 35 años de edad inicia una rehabilitación bucal mediante prótesis fija implanto-soportada, luego de haber realizado las exodoncias de las piezas remanentes en boca. Todos los implantes se mantuvieron oseointegrados a lo largo de cuatro años de seguimiento clínico y no se encontró flora periodontopática peri-implantar en los controles microbiológicos realizados. Este tipo de rehabilitación es un caso paradigmático para personas con este tipo de genodermatosis, constituyéndose en una posibilidad válida para una mejor calidad de vida frente a las circunstancias adversas que plantea la enfermedad.

Oral rehabilitation of a 35-years old female patient with Recessive Dystrophic Epidermolisis Bullosa is described. After removal of all remaining teeth, cemented implantasisted prosthesis with shortened arches were installed over three implants in the mandible and four implants in the upper jaw. At the four- year follow up, all the implants conserved osseointegration as well as absence of peri-implantar periodontopatic biofilm was observed. The success achieved in this case becomes a paradigmatic landmark for the oral rehabilitation of patients with such genodermatoses, providing a new resource to improve their quality of life. (AU)

RESUMO

RESUMEN Con miras a evaluar posibles efectos de la recomunicación del río Magdalena con su antiguo delta, se determinó la abundancia y composición de la rotiferofauna del Complejo de Pajarales (CP), durante el período de mayor abundancia anual de zooplancton. El phylum Rotifera fue seleccionado por sus altas tasas reproductivas y eficiencia en procesos de transformación energética. Las muestras se colectaron con botella van Dorn durante la segunda temporada lluviosa de 2006. En cada una de las cuatro estaciones analizadas se registraron la salinidad, temperatura, pH y oxígeno disuelto. La diversidad se calculó empleando el índice de Shannon-Wiener H’ (log10) comparando estaciones y fechas de muestreo para establecer variaciones en el período de estudio. Gráficamente se relacionaron variables fisicoquímicas con valores de diversidad que emplearon un α de 0.05 y 95% de intervalo de confianza. En total, fueron encontrados 20 morfotipos pertenecientes a las familias Brachionidae, Lecanidae, Filiniidae, Synchaetidae, Hexarthriidae y Testudinellidae, siendo Brachionidae y Lecanidae las más abundantes. La relación entre diversidad y variables fisicoquímicas, indica que la salinidad es la principal responsable de la diversidad de rotíferos. En conclusión, la rotiferofauna actual en el CP es más abundante y diversa que hace 16 años, antes de la recomunicación con el río Magdalena. Así mismo, la concentración de oxigeno disuelto, pH y salinidad son diferentes. Teniendo en cuenta que la salinidad es el factor que más influyó en la diversidad de rotíferos, la reapertura de canales probablemente favoreció el incremento en la diversidad de rotíferos en el CP.

ABSTRACT In order to assess the potential effects of the Magdalena River recommunication with its former delta, we studied the abundance and composition of the rotiferofauna of the Pajarales Complex (PC) during its highest annual zooplankton abundance. We selected the Rotifera phylum, due to its high reproductive rates and the efficiency in energetic transformation process. We sampled the rotifers with a van Dorn bottle, during the second rainy season in 2006. During each sampling we registered salinity, temperature, pH, and dissolved oxygen. We calculated the rotifer diversity using the Shannon-Wiener H’ (log10) index comparing among sampling sites and sampling dates to establish variations along the study period. The physico-chemical variables were graphically related with the diversity values calculated using 0,05 for α and 95% for the confidence interval. We found a total of 20 morphotypes belonged to Brachionidae, Lecanidae, Filiniidae, Synchaetidae, Hexarthriidae and Testudinellidae families, been Brachionidae and Lecanidae the most abundant. The relationships between diversity and physico-chemical variables, show salinity as the main responsible of the rotifer diversity. In conclusion, the current rotiferofauna in the PC is most abundant and diverse than 16 years ago, before the recommunication with the Magdalena River. Likewise, dissolved oxygen concentration, pH and salinity of the CP waters were different. Taking into account that salinity was the most influent factor in the rotiferofauna diversity, the river recomommunication probably favored the increment of rotiferofauna diversity in the PC.
