RESUMEN
Objective@#To evaluate the clinical efficacy of invisible orthodontic appliances without brackets for the distal movement of maxillary molars to improve the ability of orthodontists to predict treatment outcomes.@*Methods@#Web of Science, Cochrane Library, Embase, PubMed, Wanfang Database, CNKI Database, and VIP Database were searched for studies investigating the efficacy of invisible orthodontic appliances for distal movement of maxillary molars in adult patients and published from database inception to August 1, 2023. A total of three researchers screened the studies and evaluated their quality and conducted a meta-analysis of those that met quality standards.@*Results@#This study included 13 pre- and postcontrol trials with a total sample size of 281 patients. The meta-analysis revealed no significant differences in the sagittal or vertical parameters of the jawbone after treatment when compared with those before treatment (P>0.05). The displacement of the first molar was MD=-2.34, 95% CI (-2.83, -1.85); the displacement was MD=-0.95, 95% CI (-1.34, -0.56); and the inclination was MD=-2.51, 95% CI (-3.56, -1.46). There was a statistically significant difference in the change in sagittal, vertical, and axial tilt of the first molar before and after treatment. After treatment, the average adduction distance of the incisors was MD=-0.82, 95% CI (-1.54, -0.09), and the decrease in lip inclination was MD=-1.61, 95% CI (-2.86, -0.36); these values were significantly different from those before treatment (P<0.05).@*Conclusion@#Invisible orthodontic appliances can effectively move the upper molars in a distal direction and control the vertical position of the molars. When the molars move further away, there is some degree of compression and distal tilt movement, which is beneficial for patients with high angles. The sagittal movement of incisors is beneficial for improving the patient's profile.
RESUMEN
Background: Stunting toddlers describe the existence of chronic nutritional problems, influenced by prospective maternal, fetal period, and toddler age, including illnesses during infancy. Children who stunted impact not only on intelligence, productivity and future performance after adulthood.Methods: The study in 10 villages in Purwojati Subdistric, Banyumas district, Central Java, Indonesia in 2017. The cross-sectional study design with population is households that have children aged 6-35 months. A sample of 348 children aged 6-35 months was taken by the cluster whit design effect of 2.Results: Respondents consisted of 52.3% boys, 45.4% aged 12-23 months. Most of the energy, protein, fat and carbohydrate intake is more than 80% of the recommended dietary allowance and a small proportion of children suffer from measles, Acute Respiratory Infection and diarrhoea. For sanitation 68.4% of the houses are in the poor, poor waste management is 92%, non-plumbing sources 68.9%, dirty latrine 19.3% and the latrine was not cleaned is 92.2%. There was no average difference in z-score H/A based on nutrient intake, house status, waste management and water sources, but there were significant differences (p=0.032) on average z-score H/A based on cleaning the latrine. There was no average difference in z-score H/A based on nutrient intake, house status, waste management, and water sources, but there were significant (p=0.032) on average z-score H/A based on cleaning the latrine.
RESUMEN
Objective To assess differences between the medicine treatment level of military inpatients in military hospi-tal in 2009 and 2011 ,provide references for reasonable adjustments of health policy in future .Methods Medicine treatment da-ta from acute simple appendicitis ,coronary heart disease ,chronic bronchitis and type 2 diabetes from 16 military hospitals were excavated and analyzed by statistical methods to provide a comparative study of the medicine treatment level in 2009 and 2011 . Results 3748 cases from 16 hospitals showed the significant difference in the level of the medicine treatment in 2009 and 2011 , such as medicine cost ,medicine varieties ,primary medicine costs ,hospital daily medication cost ,and the date in 2011 is higher than 2009 .Conclusion It was showed that the medicine treatment level in four common multiple diseases in the military in 2009 and 2011 was changed .A long-term stability mechanism should be established for the evaluation of military medicine sup-port level ,which could provide strong evidence for future medicine policy adjustment .
RESUMEN
Las plantas Quassia amara y Maytenus ilicifolia son conocidas por sus propiedades terapéuticas sobre el aparato digestivo. En el presente trabajo ambas plantas se investigaron unidas, mediante la mezcla de las tinturas obtenidas, con el objetivo de potenciar su acción como fitofármaco. Este estudio resumió las propiedades físico-químicas de las tinturas obtenidas por percolación, con el empleo de una solución hidroalcóholica al 60 % y un tiempo de extracción de 48 h en 2 variantes: 1) mezclas de las tinturas obtenidas de cada planta, al 20 % en una proporción de 10-90 % (QA-MI), la cual se denominó tintura C. 2) Mezcla del material vegetal de ambas plantas en las mismas proporciones anteriores, en el equipo, para obtener la tintura D. Los parámetros evaluados en ambas tinturas (pH, densidad relativa, índice de refracción, sólidos totales), se compararon estadísticamente. Se comprobó que solo los sólidos totales ofrecen diferencias significativas, con valores superiores en la tintura D, la cual fue seleccionada para el estudio de estabilidad. El extracto D se estudió durante 3 meses a 3 temperaturas diferentes: refrigeración, ambiente y 40 °C. Se comprobó que en refrigeración no ocurren cambios en los parámetros evaluados y en las otras temperaturas aparecen ligeros cambios en pH y contenido alcohólico.
The Quassia amara and Maytenus ilicifolia plants are known by its therapeutical properties on digestive tract. In present paper both plants were researched together by means of mixing of tinctures obtained to potentiate its phytopharmacologic action. Present study summarizes the physical-chemical properties of tinctures obtained by percolation using a 60 %-hydroalcoholic solution and a extraction time of 48 hrs in two variants: 1) mixtures of tinctures obtained from each plant to 20 % at a 10-90 % ratio (QA-MI), which was called C-tincture, the mixture of vegetal material in both plants in the same prior ratios in equipment, to obtain D-tincture. Parameters assessed in both tinctures (pH, relative density, refraction rate, total solids) were statistically compared. It was proved that total solids have significant differences with higher values present in D-tincture, which was selected for stability study. D-extract was studied during three months at different temperatures: refrigeration, room-temperature and at 40 ºC. In refrigeration temperature there are not changes in parameters assessed and in the other temperatures there appear slight changes in pH and alcoholic content.
