Background: The aim of this systematic review was to examine the classification of calls for suicidal behavior in emergency medical services (EMS). Methods: A search strategy was carried out in four electronic databases on calls for suicidal behavior in EMS published between 2010 and 2020 in Spanish and English. The outcome variables analyzed were the moment of call classification, the professional assigning the classification, the type of classification, and the suicide codes. Results: Twenty-five studies were included in the systematic review. The EMS classified the calls at two moments during the service process. In 28% of the studies, classification was performed during the emergency telephone call and in 36% when the professional attended the patient at the scene. The calls were classified by physicians in 40% of the studies and by the telephone operator answering the call in 32% of the studies. In 52% of the studies, classifications were used to categorize the calls, while in 48%, this information was not provided. Eighteen studies (72%) described codes used to classify suicidal behavior calls: a) codes for suicidal behavior and self-injury, and b) codes related to intoxication, poisoning or drug abuse, psychiatric problems, or other methods of harm. Conclusion: Despite the existence of international disease classifications and standardized suicide identification systems and codes in EMS, there is no consensus on their use, making it difficult to correctly identify calls for suicidal behavior.

Objective: Purpose of this prospective study was to evaluate the skeletal and dentoalveolar effects of a fixed functional appliance, the Austro Repositioner, in dolicho- and brachyfacial skeletal Class II patients.Material and methods: In all, 20 dolicho- and 25 brachyfacial consecutive patients treated with the Austro Repositioner were compared with untreated controls (20 dolicho- and 20 brachyfacial patients) with the same initial dentoskeletal features. Lateral cephalograms were acquired before and 1.0±0.2 year after therapy.Results: Significant improvements in skeletal Class II relationships were observed in both groups. The ANB angle decreased (3.56° in dolicho- and 3.13° in brachyfacial patients, P < 0.001) due to changes localized exclusively in the mandible, the SNB angle increased to 3.20° in dolicho- and 3.02° in brachyfacial patients, and the total mandibular length (Co-Pg) increased to 6.47 mm in dolicho- and 5.78 mm in brachyfacial patients (P < 0.001). A favorable guidance of vertical pattern was also achieved in both groups, and no significant changes were observed in the upper and lower incisors in both groups.Conclusions: The Austro Repositioner was effective for short-term treatment of skeletal Class II malocclusion resulting from the retrusion of the mandible in both dolicho- and brachyfacial patients.

We prove that a topological space that admits a nontransitive totally bounded quasi-uniformity, admits at least $$2^{2^{N_0 } } $$ nontransitive totally bounded quasi-uniformities. Furthermore we show that each infinite T2-space admits at least $$2^{2^{N_0 } } $$ transitive totally bounded quasi-uniformities. In fact, each supersober space having a discrete subspace of infinite cardinality κ admits at least $$2^{2^k } $$ transitive totally bounded quasi-uniformities. [ABSTRACT FROM AUTHOR]

It is well-known that the notion of a Smyth complete quasi-uniform space provides an appropriate notion of completeness to study many interesting quasi-metric spaces which appear in theoretical computer science. We observe that several of these spaces actually possess a stronger form of completeness based on the use of weakly Cauchy filters in the sense of H. H. Corson and we develop a theory of completion and completeness for this kind of filters. In parallel, we also study a more general notion of completeness based on the use of certain stable filters. Thus our results extend and generalize important theorems of Á. Császár, J. R. Isbell and N. R. Howes on uniform completeness. [ABSTRACT FROM AUTHOR]

Objective This study aims to evaluate the relationship between the total antioxidant capacity of saliva and the presence of dental caries in deciduous and permanent teeth, in a group of Saharan children.Methods The dental examination was carried out in accordance with the recommendations of the World Health Organization (WHO). The total antioxidant capacity of the saliva was determined by colorimetry.Results The total antioxidant capacity (TAC) of the saliva of patients with caries in deciduous teeth was 2.89 1/IC50 greater than among those without. We observed a statistically significant linear regression between the number of deciduous teeth affected by caries and the total antioxidant capacity of the saliva: y = 0.24 + 0.53 × TAC saliva (t = 2.93; p = 0.004) (95% CI of b: 0.018-0.088).Conclusions Our results show that the amount of caries in deciduous teeth is in direct proportion to the observed TAC of saliva, and that the presence of caries in deciduous teeth is associated with caries in permanent teeth.
