Dental caries in primary and permanent teeth in children's worldwide, 1995 to 2019: a systematic review and meta-analysis

Background: Early childhood caries (ECC) is a type of dental caries in the teeth of infants and children that is represented as one of the most prevalent dental problems in this period. Various studies have reported different types of prevalence of dental caries in primary and permanent teeth in children worldwide. However, there has been no comprehensive study to summarize the results of these studies in general, so this study aimed to determine the prevalence of dental caries in primary and permanent teeth in children in different continents of the world during a systematic review and meta-analysis. Methods: In this review study, articles were extracted by searching in the national and international databases of SID, MagIran, IranMedex, IranDoc, Cochrane, Embase, ScienceDirect, Scopus, PubMed, and Web of Science (ISI) between 1995 and December 2019. Random effects model was used for analysis and heterogeneity of studies was evaluated by using the I2 index. Data were analyzed by using the Comprehensive Meta-Analysis (Version 2) software. Findings: In this study, a total of 164 articles (81 articles on the prevalence of dental caries in primary teeth and 83 articles on the prevalence of dental caries in permanent teeth) were entered the meta-analysis. The prevalence of dental caries in primary teeth in children in the world with a sample size of 80,405 was 46.2% (95% CI: 41.6–50.8%), and the prevalence of dental caries in permanent teeth in children in the world with a sample size of 1,454,871 was 53.8% (95% CI: 50–57.5%). Regarding the heterogeneity on the basis of meta-regression analysis, there was a significant difference in the prevalence of dental caries in primary and permanent teeth in children in different continents of the world. With increasing the sample size and the year of study, dental caries in primary teeth increased and in permanent teeth decreased. Conclusion: The results of this study showed that the prevalence of primary and permanent dental caries in children in the world was found to be high. Therefore, appropriate strategies should be implemented to improve the aforementioned situation and to troubleshoot and monitor at all levels by providing feedback to hospitals

To access the final edited and published work see https://doi.org/ 10.29077/bol.116.ce02.gomezFirst faunistic results of a collaborative study about the terrestrial invertebrates present in three small islands near the coast of the province of Almeria (Spain) are presented. A total of 385 individuals were captured (373 arthropods and 12 mollusks). From these samplings 118 different species have been identified and three others are under study. Our results provide new insight into the invertebrate diversity of these small islands. Of special interest is the finding of several rare species which could represents new taxa for science, namely a chloropid in the genus Conioscinella and a braconid of the subfamily Microgastrinae. Several new reports are also relevant, specially the first European record of the phoretic mite Hypoaspis phyllognathi. With respect to Andalusia, we provide the first record of the encirtid Ericydnus aeneus. Referring to Almería province, we report for the first time the chilopod Algerophilus hispanicus, the springtails Hemisotoma pontica, Xenylla mediterranea and Anurida maritima, and the stafilinids Aleochara bipustulata and Atheta pallidicornis. Taxa with morphological differences have been found with respect to their counterparts in the continental zone, and other rare species in the peninsular area, such as Tetragnatha intermedia or Cryptocephalus espanoli. Other records of interest about the dipteran fauna of these small islands, already published previously, are included as a comprehensive summary of the invertebrate fauna of the studied area. By islands, San Andrés and Terreros have presented the greatest variety in taxa, 61 and 60 respectively, while on Isla Negra, only 22 have been recorded

The interest of the Spanish network of investigators in back pain for rehabilitation physician

Background: The Spanish Back Pain Research Network (REIDE) brings together teams of researchers and clinicians who are interested in nonspecific neck and back pain (BP). Its objective is to improve the efficacy, safety, effectiveness, and efficiency of the clinical management of BP. Method: The Network welcomes clinicians and researchers interested in BP. The only requirement to become a member of REIDE is to take part in one of its research projects, and any member can propose a new one. The Network supports those projects that are of interest to two or more groups by assuming their administration and management, which allows the researchers to focus on their task. Its working method ensures methodological quality, a multidisciplinary approach, and the clinical relevance of those projects that are carried out. Results: 179 researchers from 11 areas in Spain are involved in REIDE, including experts in all of the relevant fields of BP research. Most Spanish studies on BP that have been published in international scientific journals come from the teams involved in REIDE, and it currently has 13 ongoing research projects. Conclusions: The Network can help to enhance research among rehabilitation specialists who are interested in BP, and can contribute to the development of research projects which are of interest to the specialty. © 2005 Sociedad Española de Rehabilitación y Medicina Física (SERMEF) y Elsevier España, S.L
